2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with

all of these warnings may cause serious injury.

3. Replace the warning labels if they become obscured or removed.

4. This band saw is designed and intended for use by properly trained and experienced personnel only.

If you are not familiar with the proper and safe operation of a band saw, do not use until proper

training and knowledge have been obtained.

5. Do not use this band saw for other than its intended use. If used for other purposes, Powermatic

disclaims any real or implied warranty and holds itself harmless from any injury that may result from

that use.

6. Always wear approved safety glasses/face shields while using this band saw. Everyday eyeglasses

only have impact resistant lenses; they are not safety glasses.

7. Before operating this band saw, remove tie, rings, watches and other jewelry, and roll sleeves up past

the elbows. Secure all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips

are recommended. Do not wear gloves when operating the machine.

8. Wear ear protectors (plugs or muffs) during extended periods of operation.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities

contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples

of these chemicals are:

•

Lead from lead based paint.

Crystalline silica from bricks, cement and other masonry products.

Arsenic and chromium from chemically treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your

exposure to these chemicals, work in a well-ventilated area and work with approved safety

equipment, such as face or dust masks that are specifically designed to filter out microscopic

particles.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. Make certain the switch is in the OFF position before connecting the machine to the power supply.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the machine unplugged from the power source.

14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting

wrenches are removed from the machine before turning it on.

15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance

purposes, use extreme caution and replace the guards immediately after maintenance is complete.

16. Make sure the band saw is firmly secured to the floor or bench before use.

17. Check damaged parts. Before further use of the machine, a guard or other part that is damaged

should be carefully checked to determine that it will operate properly and perform its intended

Exposed metal surfaces, such as the table

surface and blade guides, have been given a

protective coating at the factory. This coating

should be removed with a soft cloth moistened

with solvent. Do not get solvents near plastic or

rubber parts; and do not use an abrasive pad as

it may scratch the exposed surfaces.

Assembly

Rear Rail

Refer to Figures 4 and 5.

1. Install the rear rail to the rear edge of the

table, using three 5/16-18 x 3/4 hex cap

screws (AA), three 5/16 lock washers (BB),

and three 5/16 flat washers (CC) as shown.

Hand tighten only.

2. The exact distance from rear rail to table top

is not important, but the rear rail should be

made parallel to the table top. Place a

measuring device, such as a combination

square (Figure 5) at front and back of the

table as shown.

Download from Www.Somanuals.com. All Manuals Search And Download.

The measurement should be the same at

both ends of the rear rail. Adjust as needed.

3. Tighten the three screws with a 12mm

wrench.

Front Rail and Guide Tube

Refer to Figure 6.

4. Install the front rail to the front edge of the

table, using two 5/16-18 x 3/4 hex cap

screws (AA), two 5/16 lock washers (BB),

and two 5/16 flat washers (CC), through the

slotted holes in the rail. Place the screws

approximately center of the slots; this can

be adjusted later as needed. Tighten the

two screws with a 12mm wrench.

Figure 6

5. Install the guide tube to the bottom holes in

the front rail, using five 5/16-18 x 3/4 hex

cap screws (AA), five 5/16 lock washers

(BB), and five 5/16 flat washers (CC). Hand

tighten only. Pull the guide tube away from

the table as far as it will go, then tighten all

five screws in the guide tube with a 12mm

wrench. Do not overtighten.

Figure 7

Fence Assembly

Refer to Figures 7 and 8.

Place the fence body onto the guide tube (as

shown in Figure 8). Raise the fence lever all the

way up to install or remove the fence from the

guide tube. Midway lever position allows the

fence to slide along the guide tube. Lowest lever

position locks the fence in place.

Resaw Fence

Figure 8 (resaw fence vertical position)

Refer to Figures 8 and 9.

Loosen the lock bar using the knobs, until the

lock bar protrudes enough to slide the aluminum

resaw fence on from one end, as shown in

Figure 8. Re-tighten the knobs.

NOTE: The aluminum resaw fence can be

installed in one of two positions; vertically

(resaw position), as shown in Figure 8; or

horizontally as shown in Figure 9. Horizontal

position is useful for smaller workpieces. (The

zero setting of the cursor cannot be used with

the horizontal fence position.)

Figure 9 (horizontal fence position)

Fence to Table Clearance

1. Check the clearance between the table and

the bottom of the fence (Figure 10). The

fence should not rub against the table

surface but be slightly above it. This gap

should be the same at the front of the table

as it is at the back.

2. If the clearance is not the same, use a

Figure 10

combination

adjustments:

the

following

two

• With a 7/32” hex wrench, rotate the two

nylon adjustment screws (A, Figure 16) the

same amount to raise or lower the fence

body from the guide tube. Clockwise raises

the fence body, counterclockwise lowers.

• And/or....Adjust the back end of the fence

by loosening one hex nut and tightening the

other (A, Figure 11) in order to raise or

lower the sliding pad (B, Figure 11) as

needed. When the fence-to-table gap is

equal, make sure both hex nuts are

tightened against the fence body.

Figure 11

Setting Cursor (Zero) Position

Refer to Figure 12.

The fence must be set so that the cursor reads

zero at the line of the blade. The resaw fence

must be installed on the fence body in vertical

position, and the blade must be installed and

fully tensioned.

1. Slide the fence flush against the flat of the

blade, as shown. (Do not force the fence

into the blade so that the blade bends.)

2. If the cursor is not at zero, loosen the two

screws and slide it as needed. Then re-

tighten the screws.

Figure 12

Setting Table Parallel to Blade

Refer to Figures 13 and 14.

The table has been aligned by the manufacturer

so that the miter slot is parallel to the flat of the

blade; it should not require adjustment.

However, in the future you may wish to confirm

this setting is still accurate. A wide blade is

recommended for the procedure.

1. Disconnect band saw from power source.

2. The blade should be fully tensioned and

properly tracked (see pages 17 and 18).

3. Place a long straightedge flush against the

blade making sure it contacts both front and

back of the blade. (Do not deflect the blade

by pushing into it.) See Figure 13.

Figure 13

Download from Www.Somanuals.com. All Manuals Search And Download.

4. Use a gauge to carefully measure the

distance from miter slot to straight edge.

Take measurements at both front and back

of table – these should be the same.

5. If the miter slot is not parallel to the blade,

loosen the four hex cap screws that secure

the table to the trunnion (Figure 14 shows

three of them), and shift the table as needed

until the miter slot is parallel to the blade.

6. Tighten the four hex cap screws.

Setting Fence Parallel to Blade

Refer to Figures 15 and 16.

Figure 14

The fence should be parallel to the flat of the

blade for accurate cutting. Since the miter slot

has been set parallel to the blade from the

manufacturer (and confirmed by the user, as

described above), you can use the table miter

slot to set the fence parallelism.

1. Remove the aluminum resaw fence and the

mounting bar from the fence body, and slide

the fence body to the edge of the miter slot,

as shown in Figure 15. The fence should

align with the miter slot along the entire

length of the fence.

2. If adjustment is needed, use one of the back

adjustment screws (B, Figure 16) to turn the

fence in line with the miter slot.

Figure 15

The fence must also be parallel to the blade

vertically. Refer to Figure 17.

3. Make sure the table has been set 90° to the

blade (see “90° Table Stop”).

4. Mount the resaw fence, and slide the fence

up against the blade; do not push into the

blade. Turn either of the nylon adjustment

screws until fence is parallel to blade along

the vertical length of fence.

Figure 16

Fence Locking Tightness

The tightness of the fence against the guide

tube can be adjusted by rotating the two back

screws (B, Figure 16). Rotate the two screws

equally (clockwise to tighten) with a 5mm hex

wrench.

Because these screws are also used to align the

fence to the blade, after adjusting fence locking

tightness, you should double check fence-to-

blade relationship, as explained under “Setting

Fence Parallel to Blade.”

Dust Collection

The use of a dust collection system is strongly

recommended for this band saw. It will help

keep the shop clean, as well as reduce potential

health hazards caused by inhalation of wood

dust. The collector should have a capacity

sufficient for this size machine – 400 CFM is

recommended. Walter Meier has a line of dust

collection systems available; see your dealer or

visit our website listed on the back cover.

Connect the hoses of your dust collection

system to the 4” dust ports at the rear of the

band saw. Secure tightly with hose clamps (not

provided). See Figure 18.

Figure 18

Electrical Connections

Electrical connections must

be made by

qualified electrician in

compliance with all relevant codes. This

machine must be properly grounded to help

prevent electrical shock and possible fatal

injury.

If the single phase or three phase Band Saw is

to be “hard-wired” to a service panel, make sure

a disconnect is available for the operator. During

hard-wiring of the machine, make sure the fuses

have been removed or the breakers have been

tripped in the circuit to which the Band Saw will

be connected. Place a warning placard on the

fuse holder or circuit breaker to prevent it being

turned on while the machine is being wired.

Single Phase Connections

The single phase Band Saw is factory wired for

230 volts. It is not supplied with a plug. You may

either install a UL/CSA-listed plug suitable for

230 volt operation, or “hard-wire” the Band Saw

directly to a service panel.

It is recommended that the single phase Band

Saw be connected to a grounded and dedicated,

minimum 50 amp circuit with a 50 amp circuit

breaker or time delay fuse. Local codes take

precedence over recommendations.

Grounding Instructions

This machine must be grounded. In the event of

a malfunction or breakdown, grounding provides

a path of least resistance for electric current to

reduce the risk of electric shock.

Three Phase Connections

Improper connection of the equipment-

grounding conductor can result in a risk of

electric shock. The conductor with insulation

having an outer surface that is green with or

without yellow stripes, is the equipment-

grounding conductor.

The three phase Band Saw is factory wired for

230 volts. It is not supplied with a plug. You may

either install a UL/CSA-listed plug suitable for

230 volt operation, or “hard-wire” the Band Saw

directly to a service panel.

The three phase Band Saw may be converted to

460V operation. The current contactor must be

replaced with the 460V magnetic contactor (part

no. PM2000-293C, purchased separately). In

addition, re-connect the motor leads according

to the diagrams inside the motor junction box.

(Similar diagrams may be found at the back of

this manual.)

If repair or replacement of the electric cord or

plug is necessary, do not connect the

equipment-grounding conductor to

terminal.

live

Check with a qualified electrician or service

personnel if the grounding instructions are not

completely understood, or if in doubt as to

whether the tool is properly grounded. Repair or

replace a damaged or worn cord immediately.

It is recommended that the three phase Band

Saw be connected to a grounded and dedicated,

minimum 30 amp circuit with a 30 amp circuit

breaker or time delay fuse. Local codes take

precedence over recommendations.

Make sure the voltage of your power supply

matches the specifications on the motor plate of

the Band Saw.

Extension Cords

The use of extension cords is discouraged; try to

position the machine within reach of the power

source. If an extension cord becomes

necessary, make sure the cord rating is suitable

for the amperage listed on the machine’s motor

plate. An undersized cord will cause a drop in

line voltage resulting in loss of power and

overheating.

4. Tighten the lock lever (A, Figure 20) to

secure the setting.

NOTE: The circular plate (D) can be tightened or

loosened as desired by using a 5/32” (4mm) hex

wrench on the screw.

Also, the lever (A, Figure 20) can be pivoted to a

more convenient position. Simply lift straight out

on the lever and rotate it on the pin, then release

the lever making sure it seats itself on the pin.

90° Table Stop

Refer to Figures 20 through 22.

Figure 21

The 90° positive stop ensures that the table will

always be perpendicular to the blade after the

table is returned to horizontal position. Check

and adjust this 90° stop as follows:

1. Disconnect machine from power source.

2. Make sure blade is under full tension.

with the handwheel (B), until the stop bolt

4. Make sure the table insert is level with

surface of table by rotating one or more of

its set screws with a 5/164” (2mm) hex

wrench. Then place a square on the table

and against the blade to check that the table

is 90° to the blade. See Figure 22. NOTE:

Do not push square into blade.

5. If table and blade are not square, use a

9/16” (14mm) wrench to loosen the lock nut

(E) then rotate the stop bolt. Turn the stop

bolt as needed until there is no longer light

showing between the square and the blade.

Figure 22

6. Tighten lock nut (E) to secure the table stop

in position.

8. Check that the scale pointer (F, Figure 20)

is at zero. If necessary, loosen the screw on

the pointer and shift the pointer to zero.

Then re-tighten the screw.

Installing/Changing Blades

Always wear gloves when

handling blades. New blades are usually

packaged in a coiled position; to prevent

injury uncoil them slowly and carefully, while

wearing work gloves and safety glasses.

The PM1800 Band Saw is designed for blades

from 1/16” to 1-1/2” wide. The Band Saw is

provided with

blade of the following

specifications: 0.03” thick, 3/4” wide, 4 TPI.

1. Disconnect machine from power source.

2. Remove the table insert (A, Figure 23).

3. Pull out table pin (B) at the end of the slot.

4. Adjust upper and lower blade guides away

from the blade.

5. Move the quick tension lever to “Full

Release (Blade Change)” position.

6. Open upper and lower doors by rotating the

door catches. Open the lower blade guard

and slide out the insert block (Figure 24).

7. Carefully remove the blade from the top

wheel, then from between upper and lower

blade guides and lower wheel. Slide the old

blade out through the slot in the table.

Figure 24

8. Guide new blade through table slot. Place

blade loosely in the upper and lower blade

guides. Make sure blade teeth point down

toward table, and toward the front of the

saw. (If the teeth will not point down, no

matter how you orient the blade, then the

blade is twisted inside-out. Twist it into

correct position and re-install it.)

9. Position blade at the center of the upper and

lower wheels.

10. Re-install table insert (A) and table pin (B).

11. Before operating the band saw, the new

blade must be tensioned and tracked, in that

order. Find instructions for tensioning and

tracking the blade under “Blade Tension”

and “Blade Tracking.” The blade guides

must also be set properly according to the

instructions on pages 19 and 20.

Blade Tension

Refer to Figure 25.

1. Disconnect machine from power source.

2. Back off upper and lower guide bearings to

eliminate any contact with the blade.

3. With the blade centered on the wheels,

move the quick tension lever to “Full

Tension” position, as shown in Figure 25.

NOTE: You will be able to feel the lever fall

into each position.

4. Rotate the tension handwheel (C) until the

scale pointer (D) reaches the appropriate

measurement for the width of the blade.

Figure 25

TIP: Use the band saw’s gauge setting initially.

As you become familiar with the machine and

with the different properties of band saw blades,

you may find it necessary to change the blade

tension from the initial setting. Keep in mind that

not only changes in blade width, but also the

type of material being cut will have an effect on

blade tension. Too little or too much blade

tension can cause blade breakage and/or poor

cutting performance.

Make a note of the specific tension setting for a

particular blade. The tension can then be re-set

quickly when band saw operations are resumed.

IMPORTANT: When the band saw is not being

used, move the quick tension lever to “Partial

Tension-Idle/Tracking” position. This will prolong

the life of the blade and tires, and reduce load

on wheels, bearings and other components.

Blade Tracking

Refer to Figure 26.

After being properly tensioned, the blade must

be tracked. “Tracking” refers to the position of

the blade on the wheels while the machine is in

operation. Tracking should be checked

periodically, and is mandatory after every blade

change. Blade tracking is done by hand with the

machine disconnected from power.

1. Disconnect machine from power source.

2. The blade should be correctly tensioned.

Figure 26

3. Make sure the blade guides and other parts

of the machine will not interfere with the

movement of the blade. Lower the guide

post until you can see the blade through the

tracking window.

4. Set the quick tension lever intially to “Partial

Tension-Idle/Tracking” position, as shown in

Figure 26.

5. Open upper door to expose the upper

wheel. Rotate the wheel by hand, and

observe the position of the blade on the

wheel through the tracking window. As you

rotate the wheel, move the lever to “Full

Tension” position. The blade should

continue to ride upon the center of the

wheel (Figure 27).

Figure 27

IMPORTANT: Make tracking adjustments with

knob (F, Figure 26) while the blade is at full

tension. DO NOT use screws (G, Figure 26);

these were used by the manufacturer for wheel

alignment and should NOT be used for tracking.

6. If the blade tends to move toward the edge

of the wheel, loosen locking lever (E, Figure

26) and slightly rotate tracking knob (F) with

your right hand while continuing to rotate the

wheel with your left. Observe the blade

through the tracking window. Rotating the

tracking knob clockwise will cause the blade

to move toward the rear edge of the wheel.

Rotating the tracking knob counterclockwise

will cause the blade to move toward the

front edge of the wheel.

IMPORTANT: This adjustment is sensitive;

perform it in small increments and give the

blade time to react to the changes.

7. When the blade is tracking in the center of

the wheel, re-tighten locking lever (E), and

close upper door.

8. Move tension lever to “Full Tension”

position, and connect the band saw to

power. Turn it on for a brief time to observe

the blade in action through the tracking

window.

Download from Www.Somanuals.com. All Manuals Search And Download.

9. Make further adjustments as needed, with

the saw disconnected from power.

Upper Blade Guides

The bearing guides should be set so that

contact between blade and guides will occur

only when the blade is under pressure from a

workpiece. To adjust the upper bearing guides

for proper blade control, proceed as follows.

Refer to Figures 28 through 31.

1. Disconnect machine from power source.

2. Blade must already be tensioned and

tracking correctly. Place quick tension lever

in “Full Tension” position.

Figure 28

3. Lower the guide post until the upper guide

bearings are a few inches off the table. (The

reason for this will be shown later under

“Guide Post Parallelism.”)

4. Loosen the locking screw (A, Figure 28).

5. Move the entire guide bracket by rotating

the knurled knob (B) until the front of the

guide bearings are about 0.015” (1/64”)

behind the blade’s gullet (curved area at the

base of the tooth). See Figure 30.

6. Tighten the locking screw (A) to secure this

position.

Figure 29

7. Loosen the locking screw (C) for one of the

guide bearings.

8. The guide bearing rotates on an eccentric

shaft. Adjust the guide bearing by rotating

the knurled knob (D) until the guide bearing

is approximately 0.004” from the blade. A

quick way to achieve this spacing is by

placing a single thickness of a crisp dollar

bill (a dollar bill is approximately 0.004”

thick) between blade and guide bearing.

See Figure 31. Adjust the guide bearing

until it just lightly grips the dollar bill.

Figure 30

NOTE: Do not force the guide bearing

against the side of the blade. It should only

make contact with the blade when there is

pressure from the cutting operation.

9. Tighten locking screw (C) and remove dollar

bill.

10. Repeat process for opposite guide bearing.

Upper Thrust Bearing

Refer to Figures 29 and 32:

The thrust bearing prevents backward deflection

of the blade during cutting. The thrust bearing

has three options for stabilizing the back of the

blade (see Figure 32).

Figure 31

Download from Www.Somanuals.com. All Manuals Search And Download.

The v-shaped groove is for blades 1/8” wide or

smaller. The flat bottomed groove supports

blades over 1/8” to 3/16” wide. The non-grooved

standard bearing surface at the left is for blades

over 3/16” wide. (The blade provided with your

band saw is 3/4” wide, thus must ride along the

flat non-grooved surface of the bearing, as

shown in Figure 32.)

1. Loosen the socket head cap screw (E,

Figure 29) and push the thrust bearing

bracket laterally to desired position.

2. Re-tighten the socket head cap screw (E).

Figure 32

3. Loosen the locking screw (F) and push the

thrust bearing up to the back of the blade.

4. Adjust the thrust bearing until the space

between the thrust bearing surface (or

groove bottom) and the back edge of the

blade is approximately 0.015” (1/64”). On

the non-grooved surface, a convenient way

to achieve this spacing is by placing a dollar

bill folded twice (four thicknesses of a dollar

bill is approximately 1/64”) between blade

and thrust bearing. If using a groove, set

this distance by eye.

5. Tighten locking screw (F).

6. Make sure all locking screws on the upper

guide bearing assembly are tightened when

adjustments are finished.

Lower Blade Guides

Refer to Figure 33.

1. Disconnect band saw from power source.

2. Open lower door and lower blade guard.

3. Adjust the lower guide bearings and lower

thrust bearing below the table, using the

same procedure and measurements as for

the upper guide bearings and upper thrust

bearing described above.

Movement summary: Loosen locking lever

(G) to move guide bracket using dial (H).

Loosen knob (J) to rotate side bearings,

using (K) and (L). Loosen locking screw (M)

to slide thrust bearing toward blade.

4. Make sure all screws, knobs and lever are

tightened when adjustments are complete.

Figure 33

NOTE: The locking lever (G, Figure 33) can be

re-positioned if needed. Simply pull out on the

lever, rotate it on the hub, and release it. Make

sure it re-seats itself on the hub.

Guide Post

Refer to Figure 34.

1. Disconnect band saw from power source.

2. Loosen lock handle (A) and raise or lower

guide post by rotating the handwheel (B).

3. Position the blade guide assembly so that

the bottom of the guide bearings are about

3/16” above the material to be cut. Or,

simply lower the guide post until the scale

pointer (C) indicates the height of your

workpiece. This provides minimal clearance

between the workpiece and the bottom of

the guide bearings, which will minimize

blade deflection as well as enhance

operator safety.

Figure 34

4. Tighten lock handle (A).

Guide Post Parallelism

The guide post should be parallel to the blade

throughout the vertical travel of the guide post;

thus the guide bearings will maintain their

relationship to the blade at any height from the

table and they won’t have to be re-set each time

the guide post is moved. This setting has been

accurately made by the manufacturer and

should not require immediate attention, but it

may be checked in the future as follows:

1. Disconnect band saw from power source.

2. Move blade tension lever to “Full Tension”

position.

3. The guide bearings in low position should

already be set in relation to the blade (see

“Upper Blade Guides”). Also, the table

should be square with the blade (See “90°

Table Stop”).

4. Loosen the lock handle (A, Figure 34) and

raise the guide post to a high position.

5. Confirm that the guide post travels straight

up and down, and the guide bearings

maintain their relationship to the blade.

6. If the guide post does not go straight up and

down (the blade begins deflecting when the

guide post is raised), slightly loosen the four

hex cap screws (D, Figure 34).

7. Left and right adjustment is accomplished

using a combination of the four hex cap

screws (D); forward/back adjustment is

accomplished using the two set screws (E).

8. When finished adjusting, securely tighten

the four hex cap screws (D).

9. Re-check the setting by raising and lowering

the guide post.

Resaw Pin

Refer to Figure 35.

A resaw pin is provided with the band saw. It

provides a single contact point while ripping a

workpiece into thinner boards.

Remove the aluminum resaw fence and mount

the resaw pin to the slot in the fence body,

securing it with the knob, as shown. The resaw

pin is usually positioned so that its center is

approximately even with the front edge of the

blade.

See under “Operation” for further information on

using the resaw pin.

Figure 35

Miter Gauge

Refer to Figures 36 and 37.

A miter gauge is provided for crosscutting

operations. Install the miter gauge by sliding the

end of the miter gauge bar into the table’s T-slot.

The miter gauge should fit snugly within the

miter slot while still sliding easily. The bar of the

miter gauge has two slots, each with a set screw

(Figure 36). Rotate one or both of these set

screws with a 5/32” (4mm) hex wrench as

needed to eliminate any play between the miter

gauge bar and miter slot.

If the table/miter slot is square to the blade (see

“Setting Table Parallel to Blade”), the miter

gauge will also be square to the blade. Before

operating, however, the 90° setting of the miter

gauge should be checked in relation to the

blade, as follows.

Figure 36

1. Place a square against the miter gauge

face, and against the flat of the blade, as

shown. (Place the square against the flat of

the blade, not the teeth which are set wider

than the blade body). A wide blade is

preferred for this procedure.

2. Flip the 90° stop plate (C) out of the way,

and loosen the handle (A). Shift the miter

gauge body until it is flush with the square,

then re-tighten the handle (A).

Figure 37

3. Flip the stop plate (C) back down, and

loosen the 90° stop hex nut and adjust the

screw until it contacts the 90° stop plate.

4. Re-tighten hex nut.

5. Loosen the set screw at the base of the

pointer, and shift the pointer so that it lines

up with the 90° mark on the scale.

6. Re-tighten set screw.

Download from Www.Somanuals.com. All Manuals Search And Download.

The 45° stops can be checked in similar fashion,

using an angle gauge similar to that shown in

Figure 37.

To adjust the miter gauge angle for operations:

1. Loosen the handle (A).

2. Rotate the gauge body until the pointer (B)

lines up with the desired angle on the scale.

You may have to pivot the 90° stop plate (C)

out of the way to allow the body to rotate.

3. Tighten the handle (A).

4. There are three stops – at 90°, and 45° left

and right. Each of these can be adjusted by

loosening the hex nut (D) and turning the

screw (E) as needed. Re-tighten the hex nut

(D) when adjustment is finished.

Blade Speed Adjustment

Refer to Figures 38 through 40.

The band saw will operate at 1800 and 4200

SFPM (surface feet per minute). Figure 39

shows the appropriate belt position to achieve

each speed.

Figure 38

To change the speed:

1. Disconnect machine from power source.

2. Loosen the motor lock handle and raise the

motor lift handle to release tension on the

belt.

3. Tighten the motor lock handle to keep motor

in raised position.

4. Slide the belt onto the appropriate set of

pulleys.

5. Loosen motor lock handle and allow motor

to lower. The weight of the motor itself

should produce the proper tension for the

belt. Check the tension by pushing with

moderate pressure against the center of the

belt (Figure 40). An adequately tensioned

belt will deflect about 1/2”. If tension isn’t

strong enough, push down on the motor.

Figure 39

6. Tighten the motor lock handle.

Drive Belt Tension and Replacement

The drive belt and pulleys are properly adjusted

at the factory. However, belt tension should be

occasionally checked when the band saw is

new, as a new belt may stretch slightly during

the breaking-in process.

If the belt becomes worn, cracked, frayed or

glazed, it should be replaced as follows:

Refer to Figures 38 and 40.

1. Disconnect machine from power source.

Figure 40

Download from Www.Somanuals.com. All Manuals Search And Download.

2. Open the upper and lower doors and

remove the blade.

3. Unscrew the hex nut from the lower wheel

shaft and remove the lower wheel.

4. Loosen the motor lock handle.

5. Raise the motor lift handle and re-tighten

motor lock handle to hold motor in raised

position.

6. Remove old belt and install new one,

making sure it seats properly in the pulley

grooves.

7. Loosen motor lock handle and allow motor

to lower.

8. The weight of the motor itself should

generally produce the proper tension for the

belt. Check the tension by pushing with

moderate pressure against the center of the

belt (Figure 40). An adequately tensioned

belt will deflect about 1/2”. If tension isn’t

strong enough, push down on the motor.

9. Tighten motor lock handle, reinstall lower

wheel, and install hex nut securely on shaft.

10. Re-check blade tension and tracking before

operating the saw.

Wheel Brush

Refer to Figure 41.

The brush located next to the lower wheel must

contact the tire to clear the tire of dust and

debris before it touches the blade. Use the two

phillips head screws to make any adjustments to

the brush position.

Insert Block

Refer to Figure 41.

The insert block should remain in position to

prevent dust and chips from falling onto the

lower wheel. If it should ever become damaged,

it should be replaced. Some band saw users

make their own out of scrap wood.

Figure 41

Operating Controls

Start/Stop

Power Indicator Light – The start switch has a

power indicator lamp which is on whenever

there is power connected to the Band Saw,

not just when the Band Saw is running. Do not

assume that no light means there is no power to

the machine. If the bulb is bad, there will be no

indication. Always check before use.

Download from Www.Somanuals.com. All Manuals Search And Download.

Do not rely that no light

means no power to the machine. Always

check for power first. Failure to comply may

cause serious injury!

Refer to Figure 42:

Start – Press the green start switch.

When power is connected to the machine, the

green light is always on regardless of whether

the Band Saw is running or not.

Stop – Press the red switch to stop.

Reset – In the event that the Band Saw stops

without pressing the stop button, as the result of

a tripped fuse or circuit breaker, etc.:

Figure 42

1. Press red button to re-set main switch.

2. Press the green button to restart the

machine.

Safety Key

The start/stop switch on the Band Saw comes

equipped with a magnetic safety key. When in

place on the switch as shown in Figure 42, the

magnetic safety key trips a relay which will allow

the machine to start and stop when the

respective switches are pressed. Being

magnetic, the lock can be removed to make the

machine inoperable and can be hidden for safe

storage by attaching it to another magnetic

surface.

When using the Band Saw, place the key on the

switch cover lining up the arrow on the key with

the REMOVE arrow on the cover. Then rotate

the key so that the arrow lines up with the LOCK

arrow on the cover. This will prevent the safety

key from coming loose from vibration when the

machine is in use.

Brake Pedal

When the stop button is used to shut off the

Band Saw, the blade will coast slowly to a stop

(approximately 12 to 15 seconds). An alternate

method of stopping the machine is to press the

brake pedal, shown in Figure 43. The blade will

stop moving approximately four seconds after

the brake pedal is pressed. Re-start the saw by

pressing the start button on the column.

NOTE: Unnecessary and excessive use of the

brake pedal may shorten the life of the brake

band and brake belt.

Figure 43

After the machine is shut off,

allow the wheels and blade to come to a

complete stop before opening the doors,

making adjustments, or leaving the area.

Ripping

Operation

Ripping is cutting lengthwise down the

workpiece, and with the grain (of wood stock).

See Figure 44. Always use a push stick or

similar device when ripping narrow pieces.

The following section contains basic information,

and is not intended to cover all possible

applications or techniques using the Band Saw.

Consult published sources of information,

acquire formal training, and/or talk to

experienced Band Saw users to gain proficiency

and knowledge of band saw operations.

Crosscutting

Crosscutting is cutting across the grain of the

workpiece, while using the miter gauge to feed

the workpiece into the blade.

General Procedure

The right hand should hold the workpiece steady

against the miter gauge, while the left hand

pushes the miter gauge past the blade, as

shown in Figure 45.

1. Make sure the blade is adjusted correctly for

tension and tracking, and that upper and

lower guide bearings and thrust bearings

are set in proper relation to the blade.

Do not use the fence in conjunction with the

miter gauge. The offcut of the workpiece must

not be constrained during or after the cutting

process.

2. Adjust guide post so that the guide bearings

are just above the workpiece (about 3/16”)

allowing minimum exposure to the blade.

3. If using the fence, move it into position and

lock it to the guide rail. If you are using the

miter gauge for a crosscut, the fence should

be moved safely out of the way.

Using

the

fence

conjunction with the miter gauge can cause

binding and possible damage to the blade.

4. Turn on the band saw and allow a few

seconds for the machine to reach full speed.

Whenever possible, use a

push stick, hold-down, power feeder, jig, or

similar device while feeding stock, to prevent

your hands getting too close to the blade.

5. Place the straightest edge of the workpiece

against the fence for a rip cut; or against the

miter gauge for a crosscut. Push the

workpiece slowly into the blade, while also

keeping it pressed against the fence or held

against the miter gauge. Do not force the

workpiece into the blade.

Some further operating tips:

Figure 44

Make relief cuts whenever possible. A relief cut

is an extra cut made through the waste portion

of a workpiece up to the layout line. When that

intersection is reached by the blade while

following the layout line, the waste portion

comes free. This helps prevent pinching of the

back edge of the blade in the cut.

When cutting, do not

overfeed the blade; overfeeding will reduce

blade life, and may cause the blade to break.

When cutting long stock, the operator should

use roller stands, support tables, or an assistant

to help stabilize the workpiece.

Figure 45

Resawing

Resawing is the process of slicing stock to

reduce its thickness, or to produce boards that

are thinner than the original workpiece, such as

veneers.

The ideal blade for resawing is the widest one

the machine can handle, as the wider the blade

the better it can hold a straight line.

Resawing can be performed using the aluminum

resaw fence or the resaw pin. When using the

resaw fence, use a push block, push stick, or

similar device to keep your hands away from the

blade. The resaw pin offers a pivot point by

which you can carefully follow your layout line; it

is especially useful for sawing curves, when the

fence can’t be used and it’s difficult to control

the cut freehand.

Figure 46

Figure 46 demonstrates resawing with the

aluminum resaw fence; Figure 47, with the

resaw pin.

Blade Lead

Blade lead, or drift, is when the blade begins to

wander off the cutting line even when the band

saw fence is being used. Figure 48 shows an

example of blade lead. It is more common with

small, narrow blades, and is almost always

attributable to poor blade quality, or lack of

proper adjustments. Inspect the band saw for

the following:

Figure 47

•

Fence is not parallel to miter slot and blade.

Blade is not tensioned correctly.

Blade is dull.

Teeth have too much “set” on one side of

the blade.

•

Workpiece is being fed too quickly.

If the blade is suspect, but replacing it is not

currently an option, the blade lead can be

temporarily compensated for by skewing the

fence:

1. Cut a scrap piece of wood about the same

length as the band saw table, and joint one

edge along its length, or rip it on a table saw

to give it a straight edge.

Figure 48

5. Slide the band saw fence over against the

board until it contacts the straight edge of

the board at some point. Lock the fence

down.

2. Draw a line on the board parallel with the

jointed, or straight edge of the board.

6. Use the back adjustment screws (B, Figure

16) to line up the fence against the board.

3. Move the band saw fence out of the way,

and carefully make a freehand cut along

your drawn line on the board. Stop about

midway on the board, and shut off the band

saw (allow the blade to come to a complete

stop) but do not allow the board to move.

7. Re-tighten the four hex cap screws.

NOTE: Skewing the fence to correct blade lead

is effective for that particular blade; when a new

blade is installed, the fence will need re-

adjustment and re-squaring to miter slot. See

appropriate section in this manual.

4. Clamp the board to the table.

Maintenance

Before doing maintenance

on the machine, disconnect it from the

electrical supply by pulling out the plug or

switching off the main switch! Failure to

comply may cause serious injury.

Clean the band saw regularly to remove any

resinous deposits and sawdust.

Keep the miter slot, and the guide bearings,

clean and free of resin.

Keep the blade clean and sharp. Check it

periodically for cracks or other signs of wear.

Figure 49

The drive belt should be checked periodically. If

it looks worn, frayed, glazed or otherwise

damaged, replace it.

Remove any deposits from the band wheels to

avoid vibration and potential blade breakage.

Vacuum or blow out dust from inside the

cabinet. (Use proper dust mask equipment).

The table surface must be kept clean and free of

rust for best results. If rust appears, you can use

mixture of household ammonia, good

Figure 50

commercial detergent and #000 steel wool.

Alternatively, commercial rust removers can be

found at many hardware stores.

Apply a light coat of paste wax to the table.

There are also products in aerosol form

available in major hardware stores and supply

catalogs. Whatever method is chosen, the

coating should protect the metal and provide a

smooth surface, without staining workpieces.

If the power cord is worn, cut, or damaged in

any way, have it replaced immediately.

Lubrication Points:

Periodically apply a light, non-hardening grease

to the rack and pinion system of the guide post

(Figure 49).

Figure 51

Grease the sliding surfaces of the table

trunnions (Figure 50). Also grease the contact

area of the trunnion scale and handwheel gear

(Figure 50) and the other gears connected to the

handwheel (Figure 51).

Grease the blade tension screw (Figure 52).

Oil any pins, shafts, and joints. Do not get oil on

the pulleys or belts.

Note: Bearings on the band saw are sealed for

life and do not require lubrication.

Blade Selection

Using the proper blade for the job will increase

the operating efficiency of your band saw, help

reduce necessary saw maintenance, and

improve your productivity. Thus, it is important to

follow certain guidelines when selecting a saw

blade.

Here are factors to consider when selecting a

blade:

•

The type of material you will be cutting.

The thickness of the workpiece.

The features of the workpiece, such as

bends or curves with small radii.

Figure 53 – Blade Pitch

Shape

These factors are important because they

involve basic concepts of saw blade design.

There are five (5) blade features that are

normally changed to meet certain kinds of

sawing requirements. They are:

Figure 54 shows common types of tooth shape,

or form. Tooth shape has an effect on cutting

rate.

The Regular, or standard blade, has evenly

spaced teeth that are the same size as the

gullets, and a zero-degree rake (i.e. cutting

angle). These offer precise, clean cuts at slower

rates. It is usually a good choice for cutting

curves and making crosscuts.

1. width

2. pitch (number of teeth per inch)

3. tooth form (or shape)

4. the “set” of the teeth

5. the blade material itself

The Skip type has fewer teeth and larger gullets

with a zero rake. It allows faster cutting rates

than the Regular type, with a slightly coarser

finish. It is useful for re-sawing and ripping thick

stock, as well as cutting softwoods.

Width

Band saw blades come in different standard

widths, measured from the back edge of the

blade to the tip of the tooth. Generally, wider

blades are used for ripping or making straight

cuts, such as resawing. Narrower blades are

often used when the part being cut has curves

with small radii. When cutting straight lines with

a narrow blade, the blade may have a tendency

to drift (see “Blade Lead”).

The Hook type blade has larger teeth and gullets

and a positive rake angle for more aggressive,

faster cutting when re-sawing or ripping thick

stock, especially hardwoods.

Variable-tooth blades combine features of the

other shapes, with tooth style and spacing

varying on the same blade. This produces

smooth cuts while dampening vibration.

Pitch

Pitch is measured in “teeth per inch” (T.P.I.) and

can be constant or variable. Figure 53 shows

blades with different pitches.

A fine pitch (more teeth per inch) will cut slowly

but more smoothly. A coarse pitch (fewer teeth

per inch) will cut faster but more roughly.

As a rule of thumb, the thicker the workpiece,

the coarser will be the blade pitch. If you have to

cut a hard or very brittle material, you will

probably want to use a blade with a finer pitch in

order to get clean cuts.

Using a blade with too few teeth may cause

vibration and a rough cut, while too many teeth

may cause the gullets to fill with sawdust and

overheat the blade.

Figure 54 – Blade Tooth Shape

As a general rule, use a blade that will have

from 6 to 12 teeth in the workpiece at any given

time.

Material

Band saw blades can be made from different

types of metals. The most common include

spring steel, carbon steel, bimetal (alloy steel

equipped with a high speed cobalt steel edge

welded to it), or carbide tips.

Because of the importance of blade selection, it

is recommended that you use the blade

selection guide on page 31. Also, listening to

experienced band saw users will produce

valuable information as to the types of blades

currently on the market along with their pros and

cons.

Blade Breakage

Figure 55 – Blade Set

Band saw blades are subject to high stresses

and breakage may sometimes be unavoidable.

However, many factors can be controlled to help

prevent most blade breakage. Here are some

common causes for breakage:

Set

The term “set” refers to the way in which the saw

teeth are bent or positioned. Bending the teeth

creates a kerf that is wider than the back of the

blade. This helps the operator more easily pivot

a workpiece through curve cuts, and decreases

friction between blade and workpiece on straight

cuts.

1. Misalignment of the blade guides.

2. Feeding workpiece too quickly.

3. Using a wide blade to cut a tight radius

curve.

4. Excessive tension.

5. Teeth are dull or improperly set.

6. Upper guides are set too high off the

workpiece.

Set patterns are usually selected depending

upon the type of material that needs to be cut.

Three common set patterns are shown in Figure

55.

7. Faulty weld on blade.

Generally, the Raker set is used for cutting

metal workpieces; the Wavy set, when the

thickness of the workpiece changes, such as

cutting hollow tubing or structurals. The Straight,

or Alternate, set is the one most used for

woodworking blades, and is also used to cut

plastics.

Although not essential, some users round or

“stone” the back edge of their blade. This is

done by placing a sharpening stone on the table

and in light contact with the back corners of the

blade as the blade is running. Rounding can

help the back blade edge move more smoothly

through the kerf, smooths the weld, and helps

prevent cracks from starting at the back corners.

Blade Selection Guide

Identify the material and thickness of your workpiece. The chart will show the recommended PITCH,

blade TYPE, and FEED RATE.

Key:

H – Hook

S – Skip

L – Low

M – Medium

H – High

R – Regular

Example: 10/H/M means 10 teeth per inch / Hook Type Blade / Medium Feed

For Radius Cutting

Study the part drawing or prototype, or actually

measure the smallest cutting radius required, and

locate this radius (in inches) on the chart at the

right. Follow the curve to where the approximate

blade width is specified. If a radius falls between

two of the curves, select the widest blade that will

saw this radius.

This procedure should be used for making initial

blade selections. These recommendations can, of

course, be adjusted to meet specific requirements

of a cutting job. Compromises may be necessary if

you cannot find all needed specifications in a

single blade.

Troubleshooting – Mechanical and Electrical Problems

Trouble

Probable Cause

No incoming power.

Cord damaged.

Remedy

Machine will not

start/restart or

repeatedly trips

circuit breaker or

blows fuses.

Verify machine is connected to power

source, and that the safety key is

installed on the switch.

Replace cord.

Re-set the overload by pushing in

completely the OFF (red) button on

the magnetic switch. Allow a few

minutes for the machine to cool. If

problem persists, check amp setting

on the motor starter.

Overload automatic reset has not

been reset.

One cause of overloading trips which

are not electrical in nature is too

heavy a cut. The solution is to reduce

feed pressure into the blade. If too

heavy a cut is not the problem, then

check the amp setting on the overload

relay. Match the full load amps on the

motor as noted on the motor plate. If

amp setting is correct then there is

probably a loose electrical lead.

Band Saw frequently trips.

Check amp setting on motor starter.

Verify that band saw is on a circuit of

correct size. If circuit size is correct,

there is probably a loose electrical

lead. Check amp setting on motor

starter.

Building circuit breaker trips or fuse

blows.

If you have access to a voltmeter, you

can separate a starter failure from a

motor failure by first, verifying

incoming voltage at 220+/-20 and

second, checking the voltage

between starter and motor at 220+/-

20. If incoming voltage is incorrect,

you have a power supply problem. If

voltage between starter and motor is

incorrect, you have a starter problem.

If voltage between starter and motor

is correct, you have a motor problem.

Switch or motor failure (how to

distinguish).

Clean motor of dust or debris to allow

proper air circulation. Allow motor to

cool down before restarting.

Motor overheated.

Motor failure.

If electric motor is suspect, you have

two options: Have a qualified

electrician test the motor for function

or remove the motor and take it to a

qualified electric motor repair shop

and have it tested.

Trouble

Probable Cause

Remedy

Double check to confirm all electrical

connections are correct. Refer to

wiring diagram on page 47 to make

any needed corrections.

Machine will not

start/restart or

repeatedly trips

circuit breaker or

blows fuses.

Miswiring of the unit.

If the start/stop switch is suspect, you

have two options: Have a qualified

electrician test the switch for function,

or purchase a new start/stop switch

and establish if that was the problem

on change-out.

(continued)

Switch failure.

Band Saw does not

come up to speed.

Replace with adequate size and

length cord.

Extension cord too light or too long.

Low current.

Contact a qualified electrician.
