Grounding Instructions  
This machine must be  
grounded while in use to protect the operator  
from electric shock.  
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. This machine is equipped with an electric  
cord having an equipment-grounding conductor  
and a grounding plug. The plug must be plugged  
into a matching outlet that is properly installed  
and grounded in accordance with all local codes  
and ordinances.  
Figure 1  
230 Volt Operation  
To convert the JWBS-18QT from 115V to 230V,  
single phase operation, the following is strongly  
recommended:  
Do not modify the plug provided. If it will not fit  
the outlet, have the proper outlet installed by a  
qualified electrician.  
Contact your local Authorized JET Service  
Center or qualified electrician for proper  
procedures to install the plug. The band saw  
must comply with all local and national codes  
after the 230V plug is installed.  
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. If repair or replacement of  
the electric cord or plug is necessary, do not  
connect the equipment-grounding conductor to a  
live terminal.  
Change the lead wires at the motor junction box  
as shown in B, Figure 2.  
The 115V attachment plug supplied with the  
band saw (C, Fig. 2) must be replaced with a  
UL/CSA listed plug suitable for 230V operation  
(D, Fig. 2).  
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. Use only  
three wire extension cords that have three-prong  
grounding plugs and three-pole receptacles that  
accept the tool’s plug.  
The band saw with a 230V plug should only be  
connected to an outlet having the same  
configuration (D, Fig. 2). No adapter is available  
or should be used with the 230V plug.  
Important: In all cases (115 or 230 volts), make  
certain the receptacle in question is properly  
grounded. If you are not sure, have a registered  
electrician check the receptacle.  
Repair or replace a damaged or worn cord  
immediately.  
Model JWBS-18QT  
Model JWBS-18QT Band Saw has a 1-3/4 HP 1  
phase motor and is wired from the factory for  
115 volt operation, but can be rewired for 220  
volts.  
115 Volt Operation  
The JWBS-18QT Band Saw comes equipped  
with a plug that looks like A, Fig. 1. and is used  
in an outlet that looks like B, Fig. 1. A temporary  
adapter with a grounding ear secured with a  
screw (C, Fig. 1) may be used to connect this  
plug to a two-pole receptacle if a properly  
grounded outlet is not available. The temporary  
adapter should only be used until a properly  
grounded outlet can be installed by a qualified  
electrician. This adapter is not applicable in  
Canada. The green colored grounding ear, lug,  
or tab, extending from the adapter, must be  
connected to a permanent ground such as a

* Local codes take precedence over recom-  
mendations.  
If the band saw is to be hard-wired to a panel,  
make sure a disconnect is available for the  
operator. During hard-wiring of the band saw,  
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.

Extension cords  
NR: Not Recommended.  
The use of an extension cord is not  
recommended for this band saw. Try to position  
your machine within reach of the power supply.  
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.  
Table 2  
Use the chart in Table 2 as a general guide in  
choosing the correct size cord. If in doubt, use  
the next heavier gauge. The smaller the gauge  
number, the heavier the cord.

Unpacking  
Remove the crate and packing material from the  
band saw except for the transport skid on the  
bottom. Inspect the machine for damage. Report  
any damage to your distributor and shipping agent.  
Move the saw to its permanent working location.  
The site should be dry, well lit, and have enough  
room to handle long stock and the service and/or  
adjustment of the machine from any side.  
Move the band saw off the skid. Clean all rust  
protected surfaces with a mild solvent or diesel fuel  
and a soft cloth. Do not use lacquer thinner, paint  
thinner, or gasoline. These will damage painted  
surfaces.

Fence Adjustment  
2. Place the fence assembly onto the guide  
rail (D, Fig. 9) and against the edge of the miter  
slot (C, Fig. 9). The hook at the rear of the  
fence should fit under the rear rail (see Figure  
12).  
The fence must align parallel to the miter slot along  
the entire length of the fence.  
If adjustment is necessary:  
3. Lock the fence by pushing down the lock  
handle (A, Fig. 9). Because the screws are only  
hand-tight, you can shift the fence slightly as  
needed until the fence is parallel the miter slot.  
4. When the fence has been properly aligned to  
the miter slot, tighten the four socket head cap  
screws (B, Fig. 9) with a 6mm hex wrench.  
Make sure the fence remains parallel to the  
miter slot as you tighten the screws.  
Note: This alignment will again be checked  
once the guide rail has been tightened.  
Figure 9  
5. Move the fence assembly to the other side of  
the blade as shown in Figure 10 so that the  
pointer (B, Fig. 10) on the fence body points to  
zero on the scale. Lock the fence by pushing  
the handle (A, Fig. 10) down.  
6. Move the guide rail (D, Fig. 10) with the locked  
fence until the fence is flush against the blade  
(C, Fig. 10). Do not unlock the fence to perform  
this. Move the fence and guide rail together  
when establishing the zero point.  
Important: Do not force the fence into the  
blade so that the blade bends.  
7. With a 10mm wrench, tighten the five hex cap  
screws located on the bottom of the front rail  
that hold the guide rail to the front rail.  
Note: After tightening the guide rail, double  
check that the fence is still parallel to the miter  
slot. Make additional adjustments if needed.

Adjusting Clearance between Fence and Table  
Referring to Figures 11 and 12:  
Check the clearance between the table and the  
fence. 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 rear.  
Figure 11  
If the gap between fence and table is not  
consistent, loosen either of the hex nuts on the  
hook (Figure 12) and rotate the sliding pad until the  
fence/table gap is consistent across the full length  
of the table. When this is achieved, tighten both  
hex nuts.  
Check the adjustment of the hook at the rear of the  
fence. The hook should be positioned so that it  
overlaps the rear rail by approximately 1/8”  
(Fig. 12). To adjust the hook, loosen the upper hex  
nut and slide the hook in or out as needed. Re-  
tighten upper hex nut.  
Figure 12  
Resaw Guide  
For resawing attach the post (A, Fig. 13) to the  
fence with the lock knob (B, Fig. 13). There is a  
slotted hole in the fence that will accommodate the  
resaw kit. Position the post so that it is centered  
with the front edge of the blade. The resaw guide  
will give you a taller, single point contact surface  
during resawing.  
Miter Gauge  
1. Place the miter gauge in the table slot.  
2. With a square verify the miter gauge face is  
square to the blade.  
Figure 13  
3. If the miter gauge is not square to the blade  
loosen the lock knob (C, Fig. 13) and adjust to  
the proper setting. Tighten the lock knob.  
4. If the pointer is not at 90 degrees, loosen the  
screw (D, Fig. 13) holding the pointer and move  
the pointer to 90 degrees.  
5. Re-tighten the screw.

Installing/Changing Blades  
Disconnect machine from  
power source. Blade teeth are sharp, use care  
when handling the blade. Failure to comply may  
cause serious injury.  
1. Disconnect machine from power source.  
2. Place the mode selection lever (J, Fig. 18) in  
the Full Release (Blade Change) position.  
Note 1: When changing the position of the  
mode selection lever, the machine must be  
turned off.  
Note 2: The blade tension handwheel  
(A, Fig. 17) is primarily used for initial blade  
tension adjustments (described on following  
page).  
3. Remove the table insert (B, Fig. 17).  
4. Remove the tapered pin (C, Fig. 17) by using  
the wrench attached together with the pin.  
5. Lower the upper blade guide assembly  
(F, fig. 17) by loosening the knob (H, Fig. 18)  
and rotating the handwheel (G, Fig. 18) clock-  
wise.  
6. Open upper and lower front doors (D, Fig. 17).  
7. Carefully remove the blade from between  
upper and lower blade guides and upper and  
lower wheels; then remove blade through the  
table slot (E, Fig. 17).  
8. Guide new blade through table slot (E, Fig. 17).  
Place blade in upper and lower blade guides.  
Figure 17  
Note: Make sure blade teeth point down  
toward table (see inset, Fig. 17), and toward  
the front of the saw.  
Hint: If the teeth cannot be made to point  
down, try turning the blade inside out first, then  
reattempt.  
9. Position blade on the middle of the upper and  
lower wheels.  
10. Replace the table insert (B, Fig. 17) and  
tapered pin (C, Fig. 17).  
11. Place the lever (J, Fig. 18) to the Full Tension  
or Partial Tension (Idle/Tracking) position.  
Before operating the band saw, the new blade must  
be adjusted and blade guides re-adjusted. The  
required adjustments are contained in the sections  
listed below and which follow immediately:

Blade Tension  
Blade tension is set with the blade tension  
handwheel (A, Fig. 19) and is performed following  
blade replacement and periodically as the blade  
stretches from use.  
Disconnect machine from  
power source before making any adjustments.  
Referring to Figure 19:  
1. Place the mode selection lever (F) in the Full  
Tension position (see Figure 18).  
2. Set the blade tension by rotating the  
handwheel (A) according to the arrow  
directions shown in Figure 19.  
The gauge (B) indicates the approximate  
tension according to the width of the blade in  
inches. Initially, set the blade tension to  
correspond to the width of your blade.  
The JWBS-18QT comes with a 3/4" blade so  
the tension should be set at 3/4" when using  
this blade.  
Figure 19  
The JWBS-20QT comes with a 1" blade so the  
tension should be set at 1" when using this  
blade.  
1. Open upper front door to expose the wheel.  
Rotate the wheel clockwise by hand and  
observe the position of the blade on the wheel  
through the window (E, Fig. 19). The blade  
should ride upon the center of the wheel as  
shown in Figure 20.  
Note: For the JWBS-18QT the tension gauge  
can also be seen from the front of the saw  
through the wheel when the upper door is open.  
As you become familiar with the saw, you may find  
it necessary to change the blade tension from the  
initial setting.  
2. If the blade tends to move toward the edge of  
the wheel, loosen the wing nut (D, Fig. 19) and  
slightly rotate the knob (C, Fig. 19). Rotating  
the knob clockwise will cause the blade to  
move toward the rear edge of the wheel.  
Rotating the knob counterclockwise will cause  
the blade to move toward the front edge of the  
wheel.  
Keep in mind that too little or too much blade  
tension can cause blade breakage and/or poor  
cutting performance.  
Tip: When the band saw is not being used, place  
the mode selection lever (J, Fig. 18) to the Partial  
Tension position – this will prolong the blade’s life.  
Note: This adjustment is sensitive; perform it in  
small increments and give the blade time to  
react to the changes as you continue to rotate  
the wheel.  
Blade Tracking  
Tracking refers to the position of the saw blade on  
the wheels while the machine is in operation.  
Tracking has been factory-adjusted. However, it  
should be checked occasionally, including after  
every blade change.  
3. When the blade is tracking properly in the  
center of the wheel, re-tighten the wing nut  
(D, Fig. 19).  
4. Close the upper front door.  
Disconnect machine from  
power source before making any adjustments.  
Important: The blade must be in Full or Partial  
Tension positions before adjusting blade tracking  
(see previous section). Make sure the blade guides  
and other parts of the machine will not interfere  
with the movement of the blade.  
Figure 20  
To inspect and adjust tracking, proceed as follows:

Overview – Bearing Adjustments  
Thrust (back support) bearing are located behind  
the saw blade and provide support to the back of  
the blade when the saw is in operation.  
Guide bearings are located on either side of the  
saw blade and provide stability for the blade when  
the saw is in operation. These bearings rotate on  
an eccentric shaft so the distance from the blade  
can be adjusted for optimal performance.  
Upper Bearing Adjustments  
Unplug the machine from power  
source before making any adjustments! Blade  
teeth are sharp - use care when working near  
the saw blade. Failure to comply may cause  
serious injury.  
Note: Blade tension and tracking must be properly  
adjusted prior to bearing guide setup. Refer to the  
Blade Tension section (previous page).  
To adjust the thrust bearing:  
1. Place the mode selection lever (J, Fig. 18) in  
the Full Tension position.  
Referring to Figure 21:  
2. Loosen the wing nut (E) and slide the bearing  
and bearing post until the space between the  
thrust bearing (H) and the back edge of the  
blade (G) is approximately 1/64”.  
Figure 21  
A convenient way to achieve this spacing is by  
placing  
a
dollar bill folded twice (four  
thicknesses) between the blade and support  
bearing – four thicknesses of a dollar bill is  
approximately 1/64”.  
3. Tighten wing nut (E).  
To adjust the guide bearings (refer to Figure 22):  
4. Loosen the locking handle (L) and slide the  
assembly until the front of the guide bearings  
rest just behind the gullet of the blade teeth  
(see inset).  
5. Loosen two wing nuts (J1, J2). Rotate the  
adjustment handles (M) until the guide bearings  
(K) rest lightly against the blade (N). Do not  
force the guide bearings against the side of the  
blade.  
6. Tighten wing nuts (J1, J2 Fig. 22).  
Check to make sure the adjustments have not  
changed and the bearing guides do not pinch the  
blade.  
Place the mode selection lever (J, Fig. 18) in the  
Partial Tension position when the machine is not in  
use.

Lower Bearing Adjustments  
Unplug the machine from power  
source before making any adjustments! Blade  
teeth are sharp - use care when working near  
the saw blade. Failure to comply may cause  
serious injury.  
Note: Blade tension and tracking must be properly  
adjusted prior to bearing guide setup. Refer to the  
Blade Tension section (page 16).  
1. Place the mode selection lever (J, Fig. 18) in  
the Full Tension position.  
Referring to Figure 23:  
2. Loosen the thumb screw (B).  
This will allow the thrust bearing (A) to move  
freely and prevent interference with the saw  
blade (C) during the following steps.  
Guide Gearings Adjustment  
3. Loosen the locking handle (D) then turn the  
adjustment screw (E) to adjust the assembly  
forward or backward until the front of the guide  
bearings (F) rest just behind the gullet of the  
blade teeth (C and inset).  
4. Tighten the locking handle (D).  
Thrust Bearing Adjustment  
5. With the thumb screw still loose (from Step 1),  
slide the thrust bearing and bearing post until  
the space between the bearing (A) and the  
back edge of the blade (C) is approximately  
1/64”.  
Figure 23  
A convenient way to achieve this spacing is by  
placing  
a
dollar bill folded twice (four  
thicknesses) between the blade and support  
bearing – four thicknesses of a dollar bill is  
approximately 1/64”.  
6. Tighten the thumb screw (B).  
7. Loosen the lock knob (G). Rotate the  
adjustment handles (H) until the guide bearings  
(F) rest lightly against the blade (C). Do not  
force the guide bearings against the side of the  
blade.  
8. Tighten the lock knob (G).  
Check to make sure the adjustments have not  
changed and the bearing guides do not pinch the  
blade.

Blade Lead  
Blade drift (also known as lead or fence drift) is a  
problem that may occur when the blade begins to  
wander off the cutting line even when the band saw  
fence is being used. Figure 24 shows an example  
of blade lead.  
Blade lead can be caused by a number of factors,  
and these should all be checked and corrected if  
necessary:  
ˆ Fence is not parallel to miter slot and  
blade.  
ˆ Blade is not tensioned correctly.  
ˆ Blade is dull.  
ˆ Teeth have too much “set” on one side of  
the blade.  
If replacement of the blade is not currently an  
option, the blade lead can be compensated for by  
skewing the fence. Proceed as follows:  
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 24  
2. Draw a line on the board parallel with the  
jointed, or straight edge of 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.  
4. Clamp the board to the table.  
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.  
6. Loosen the four hex cap screws at the top of  
the fence (see Figure 9) and shift the fence  
until it is parallel to the board along its length.  
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 probably need re-  
adjustment.

Changing the Blade Speed  
Disconnect machine from  
power source before making any adjustments.  
The JWBS-18QT and -20QT band saw has two  
blade-speed options which is determined by the  
position of the pulley drive belt. Refer to the  
Specifications section (page 6) for speed specs.  
To change the blade speed (while referring to  
Figure 25):  
1. Loosen the lock handle (A) that secures the  
motor (C).  
2. Release belt tension by pulling handle (B) up  
which raises the motor, then tighten lock  
handle (A).  
Figure 25  
3. Open the lower wheel door (C, Fig. 27).  
4. Referring to Figure 26:  
For higher blade-speed – place the poly V-belt  
in the A position on the spindle and motor  
pulleys as shown in Figure 26.  
For lower blade-speed – place the poly V-belt  
in the B position on the spindle and motor  
pulleys.  
After repositioning the belt:  
5. Unlock lock handle (A, Fig. 25). Apply belt  
tension by slightly pushing handle (B, Fig. 25)  
down.  
6. Tighten the lock handle (A, Fig, 25) to secure  
the motor (C, Fig. 25).  
Belt Tension  
The drive belt and pulleys are properly adjusted at  
the factory. However, belt tension should be  
occasionally checked. The belt will need to be re-  
tensioned after belt replacement.

Replacing the Poly V-Belt  
Disconnect machine from  
power source before making any adjustments.  
1. Place the mode selection lever (J, Fig. 18) in  
the Full Release position.  
Referring to Figure 25:  
2. Loosen the lock handle (A) that secures the  
motor (C).  
3. Release belt tension by pulling handle (B) up  
which raises the motor, then tighten lock  
handle (A).  
4. Open the lower wheel door (C, Fig. 27) and  
remove the hex nut and washer (D, Fig. 27).  
5. Remove the wheel (E, Fig. 28). If the lower  
wheel does not come off easily you may need  
to use a pulley puller to remove it.  
Figure 27  
Note: If you are doing a pulley alignment only, skip  
Step 6.  
6. Remove the old belt (F, Fig. 28) and install the  
new belt.  
Note: For higher blade-speed, place the belt on  
the pulleys closest to the motor (A, Fig. 26). For  
lower blade-speed, place the belt on the  
pulleys away from the motor (B, Fig. 26).  
Since the wheel is still off, this is the most  
convenient time to check the wheel and motor  
pulley alignment. Jump to the Pulley Alignment  
procedure (following page) at this time. At the  
conclusion you will be redirected back here.  
After the pulley alignment (if performed) is  
complete:  
7. Reinstall the lower wheel, hex nut and washer  
and tighten the hex nut.  
8. Unlock lock handle (A, Fig. 25). Apply belt  
tension by slightly pushing handle (B, Fig. 25)  
down.

Pulley Alignment  
The pulley alignment is done in conjunction with the  
poly V-belt replacement.  
If you are just beginning the alignment, start with  
the Replacing the Poly V-Belt section (previous  
page.  
If you were directed here, proceed as follows:  
1. Uses a straight edge placed against the wheel  
pulley and motor pulley and refer to Figure 29  
to determine if alignment is necessary.  
If alignment is necessary:  
2. With a 4mm hex wrench, loosen two set screws  
on the motor (lower) pulley.  
3. Adjust the motor pulley by sliding in or out.  
4. Confirm the alignment of the poly V-belt by  
placing a straight edge against the faces of  
both pulleys, (Figure 29). If the straight edge  
lies flush against both pulleys, then the pulleys  
and belt are aligned.  
5. Re-tighten the two set screws on the motor  
pulley.

The switch shown in Figure 31 is a magnetic  
switch used on the JBWS-18QT-3 and all  
JBWS-20QT model band saws.  
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 no  
indication. Always check before use.  
Figure 31 – Magnetic Start/Stop Switch

Ripping  
Operation  
Note: The following Figures may or may not  
show your particular band saw model, but the  
procedures are identical.  
Ripping is cutting lengthwise down the  
workpiece, and with the grain (of wood stock).  
See Figure 34.  
General Procedure  
1. Make sure the blade and upper and lower  
bearings are properly adjusted for tension  
and tracking.  
2. Adjust blade guide assembly so that the  
guide bearings are just above the workpiece  
(about 3/16”) allowing minimum exposure to  
the blade. See Figure 33.  
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.  
Figure 34  
4. Turn on the band saw and allow a few  
seconds for the machine to reach full speed.  
Crosscutting  
Crosscutting is cutting across the grain of the  
workpiece, while using the miter gauge to feed  
the workpiece into the blade.  
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.  
Slide the bar of the miter gauge into the end of  
the slot on the table.  
5. Place the straightest edge of the workpiece  
against the fence, and push the workpiece  
slowly into the blade. Do not force the  
workpiece into the blade.  
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 35.  
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.  
When cutting, do not  
overfeed the blade; overfeeding will reduce  
blade life and may cause the blade to break.  
6. When cutting long stock, the operator should  
use roller stands, support tables, or an  
assistant to help stabilize the workpiece.  
Using  
the  
fence  
in  
conjunction with the miter gauge can cause  
binding and possible damage to the blade.  
Figure 33

the tip of the tooth. Generally, wider blades are  
used for ripping or making straight cuts;  
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 wander, causing  
blade lead. (refer to the Blade Lead section in  
Adjustments).  
Resawing  
Resawing is the process of slicing stock to  
reduce its thickness, or to produce boards that  
are thinner than the original workpiece.  
Figure 36 demonstrates resawing.  
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.  
Pitch  
When resawing thin stock, use a push block,  
push stick, or similar device to keep your hands  
away from the blade.  
Pitch is measured in "teeth per inch" (TPI).  
Figure 37 shows blades with different pitches. A  
fine pitch (more teeth per inch) will cut slower  
but smoother. A coarse pitch (fewer teeth per  
inch) will cut rougher but faster. 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  
good clean cuts.  
General rule: Use a blade that will have no  
fewer than 6 and no more than 12 teeth in the  
workpiece at any given time.  
Figure 36  
Saw 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.  
Figure 37  
Here are factors to consider when selecting a  
blade:  
Shape  
ˆ The type of material you will be cutting.  
ˆ The thickness of the workpiece or part.  
Figure 38 shows common types of tooth shape.  
Tooth shape has an effect on cutting rate, and  
with few exceptions, the Skip and Hook types  
are used to obtain higher feed rates when  
cutting thick workpieces. Variable-tooth blades  
are also available, which combine features of  
the other styles.  
ˆ The features of the workpiece or part,  
such as bends or curves with small radii.  
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:  
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.  
Width  
Band saw blades come in different standard  
widths, measured from the back of the blade to  
Figure 38  
25

1. Misalignment of the blade guides  
2. Feeding work too fast  
Set  
The term "set" refers to the way in which the  
saw teeth are bent or positioned. Set patterns  
are usually selected depending on the type of  
material that needs to be cut. Three common set  
patterns are shown in Figure 39.  
3. Using a wide blade to cut a short radius  
curve  
4. Excessive tension  
5. Teeth are dull or improperly set  
Generally, the Raker set is used for cutting  
metal workpieces; the Wave set, when the  
thickness of the workpiece changes, such as  
cutting hollow tubing or structurals. The Straight  
set is most often preferred when cutting wood or  
plastics.  
6. Upper guides are set too high off the  
workpiece  
7. Faulty weld on blade  
Maintenance  
Before any intervention on  
the machine, disconnect it from the electrical  
supply by pulling out the plug. Failure to  
comply may cause serious injury.  
Keep bearing guides clean and free of build-up.  
Check that the cleaning brush over the band  
wheel is working properly, and remove any  
deposits from the band wheels to avoid vibration  
and blade breakage.  
The table surface should be kept clean and free  
of rust for best results. Some users prefer a  
paste wax coating. Another option is talcum  
powder applied with a blackboard eraser rubbed  
in vigorously once a week; this will fill casting  
pores and form a moisture barrier. This method  
provides a table top that is slick and allows rust  
rings to be easily wiped from the surface.  
Important also is the fact that talcum powder will  
not stain wood or mar finishes as wax pickup  
does.  
Figure 39  
Material  
Band saw blades can be made from different  
types of materials. Some of the most common  
include spring steel, carbon steel, carbon steel  
equipped with a high speed or welded edge (bi-  
metal), or carbide tips. A special type of saw  
blade is made from "high speed steel"; these  
should not be used on band saws with low rates  
of speed.  
Do not let saw dust build up in the upper and  
lower wheel housings. Vacuum out frequently.  
Because of the importance of blade selection, it  
is recommended that you use the Blade  
Selection Guide on page 27.  
Connect the band saw to a JET dust collection  
system.  
Clean and grease the raising/lowering rack for  
the upper bearing guides if it becomes difficult to  
raise or lower.  
When cutting, do not  
overfeed the blade; overfeeding will reduce  
blade life, and may cause the blade to break.  
Clean and oil the tensioning mechanism if it  
becomes difficult to adjust.  
Blade Breakage  
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:  
Vacuum out the motor fan cover.

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.
