4. This sander 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 sander, do not use until proper training

and knowledge have been obtained.

5. Do not use this sander for other than its intended use. If used for other purposes, WMH Tool Group

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 sander. Everyday eyeglasses only

have impact resistant lenses; they are not safety glasses.

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

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

are recommended. Do not wear gloves.

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

contain 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.

16. Make sure the sander is firmly secured to the stand or work table 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

blahblahblah

21. Make your workshop child proof with padlocks, master switches or by removing starter keys.

22. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are

careless acts that can result in serious injury.

23. Maintain a balanced stance at all times so that you do not fall or lean against moving parts. Do not

over-reach or use excessive force to perform any machine operation.

24. Stand to one side of the conveyor and make sure no one else is standing in line with the conveyor

while feeding stock into the machine. Should a part slip while being fed, it may exit the machine at a

high rate of speed and can cause injuries to anyone standing directly in front of the infeed.

25. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for

which it was not designed. The right tool will do the job better and safer.

26. Use recommended accessories; improper accessories may be hazardous.

27. Maintain tools with care. Keep abrasives clean for the best and safest performance. Follow

instructions for lubricating the machine and changing accessories.

28. Always feed stock against the rotation of the drum.

29. Keep your hands clear when feeding parts onto the conveyor. The part will be forced down as it

begins to feed, causing a pinching action between the part and the conveyor bed. Never reach into a

running machine. Turn off sander and disconnect from power before attempting to retrieve parts from

within the machine.

30. Turn off the machine and disconnect from power before cleaning. Use a brush or compressed air to

remove chips or debris — do not use your hands.

31. Do not stand on the machine. Serious injury could occur if the machine tips over.

32. Never leave the machine running unattended. Turn the power off and do not leave the machine until it

comes to a complete stop.

33. Remove loose items and unnecessary work pieces from the area before starting the machine.

Assembling the Sander

Tools Required for Assembly (not provided):

Ratchet wrench with extension

7/16”, 9/16” and 1/2” sockets

9/16” open-end wrench

Flat blade screwdriver

Installing Drum Head

1. Lift the drum head assembly out of the box,

and temporarily rest it crosswise on top of

the stand. (If your stand has casters, make

sure they are locked.)

Figure 5

The drum head is heavy; use

an assistant to help lift if needed.

2. Mount the knob to the height adjustment

handle. See Figure 5. Tighten the hex nut

against the handle base with a 9/16”

wrench.

3. Rotate the height adjustment handle

clockwise to raise the drum and free the

wood support blocks.

4. Use a 9/16” socket wrench to remove the

hex cap screws and flat washers which

secure the plywood boards to the bottom of

the sander base. Retain these screws and

washers for step 6.

5. Position the drum head assembly on top of

the stand so that the four threaded holes of

the base align with the holes in the long rails

of the stand (Figure 6).

[NOTE:The four holes at the center of the

long rails are not used with the 16-32 Plus.]

Figure 6

6. Fasten base to stand (from beneath) with

the four screws and flat washers that you

removed from the plywood boards. See

Figure 6. Tighten the screws securely.

Installing Conveyor

1. Raise the sanding drum to its highest

elevation by rotating the height adjustment

handle (Figure 5) in a clockwise direction.

2. Install the conveyor bed to the base so that

the conveyor mounting holes align with the

holes in the base. Install four 5/16” hex

washer head screws (A, Figure 7).

3. Insert plug of motor cord (B, Figure 7) into

the control box receptacle.

Figure 7

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

IMPORTANT: The conveyor belt has been over-

tensioned for shipping purposes. It must be re-

tensioned before operating the sander! See

“Conveyor Belt Tension/Tracking” on page 16.

Infeed/Outfeed Tables (Optional

Accessory)

The sander should be bolted to the stand or a

work table when using these table extensions.

Maximum working load of a table is 35 pounds.

1. Install a bracket (A, Figure 8) to the two

holes in the sander base with a 9/16”

wrench, using two hex cap screws (B), two

flat washers (C) and two flanged lock nuts

(D). The bracket should be flush against the

base. Make sure the slotted holes for

mounting the table are facing up, as shown

in Figure 8. Tighten the flanged lock nuts

(D) against the inside of the sander base.

Figure 8

2. Place the table (E, Figure 8) over the

bracket and insert four carriage bolts, (F) flat

washers (G) and hex nuts (H), as shown.

Finger tighten only.

3. Position the table slightly below the

conveyor belt surface for proper support of

stock. To check position, place a straight-

edge on one side of the conveyor bed under

the sanding drum and extending out over

the table. Lower the sanding drum to

securely hold the straight-edge in place.

See Figure 9. Raise the infeed/outfeed table

until the table surface is slightly below the

conveyor belt surface. Tighten hex nuts (H,

Figure 8) with a 7/16” wrench. Repeat this

procedure for other side of table.

Figure 9

4. Install the other bracket and table to the

opposite side of the base in the same

manner.

NOTE: If after adjusting the infeed/outfeed

tables, they are still too high for proper

operation, the bracket may not be “set.” To set

the bracket, slightly loosen the flanged hex nuts

(D, Figure 8) and firmly push down on the

bracket. Securely re-tighten the flanged hex

nuts.

If the stock being sanded is bowed, warped or

otherwise inconsistent, be sure the tables are

lower than the top of the conveyor bed.

If stock slips on the conveyor, the tables may be

positioned too high. Lower tables to allow stock

to remain in contact with the conveyor.

Dust Collection

Dust collection is mandatory for a safe work

environment and extended abrasive life. The 16-

32 Plus is equipped with a 4” dust collection port

at the top of the dust cover. It is designed to be

used with standard 4” dust collection hose

connected to a high volume dust collector

(minimum 400 to 600 cfm).

A standard shop type canister (16 gal. or larger)

can be used for short periods of sanding time

but requires converting the hose size down to 2-

1/2”. An adapter is available for converting to the

2-1/2” hose (see “Optional Accessories” on page

26).

Installing Abrasives

An 80-grit abrasive strip is already installed on

the drum of your sander, and one box of

assorted grit Ready to Wrap^TMabrasives is also

supplied. Page 25 offers information on the

types of abrasive and their recommended uses.

Proper attachment of the abrasive strip to the

drum is critical to achieving top performance

from your drum sander. Abrasive strips do not

have to be pre-measured. The end of the roll is

first tapered and attached to the left (outboard)

side of the drum. Then the strip is wrapped

around the drum, and the second taper is made

for attachment to the right (inboard) side of the

drum.

Figure 10

(not applicable to “Ready To Wrap” strips)

NOTE: When using Ready To Wrap^TM

abrasives, not all of the steps below are

necessary. You can use the original abrasive

strip mounted to the drum as a template for

cutting your own strips.

1. Mark and cut a taper at one end of the roll

as shown in Figure 10. Because the tapered

end should use all of the left (outboard) slot

width, its end must be trimmed back as

shown.

Figure 11

2. Squeeze the fastener lever (Figure 11) on

the outboard end of drum, and insert the

tapered end of the abrasive so that it uses

most of the width of the slot. Release the

fastener lever to securely hold the strip end

to the fastener.

3. Begin wrapping the strip around the drum.

The tapered edge of the strip end should

follow the edge of the drum.

4. Continue to wrap the abrasive in a spiral

fashion by rotating the drum with one hand

and guiding the strip with the other (Figure

12). Successive windings of the strip should

be flush with previous windings without any

overlap.

Figure 12

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

5. Mark the trailing end of the strip where it

crosses the right (inboard) end of the drum

(Figure 13).

6. Remove the abrasive strip from the drum,

and cut a taper as was done with the

starting edge (see Figure 10). Note: The

taper on the remaining roll can be used as

the taper for the starting edge of the next

strip to be cut.

7. Rewrap the drum beginning at the left, as

described in steps 2-4 .

8. You can use your fingers to work the infeed

take-up fastener, but it will be more

convenient to use the TUFTool supplied

with your sander. Hold the TUFTool with the

red end pointing away from you (Figure 14)

and insert its hook into the outside hole of

the fastener lever (see Figure 16).

Figure 13

9. Lift the lever with the TUFTool, pulling the

lever up until it touches the inside of the

drum.

10. Turn the TUFTool counterclockwise and

lower it onto the abrasive strip, making sure

it is holding the paper tight (Figure 15).

11. Insert the tapered end of the abrasive strip

into the slot and fastener. It may be

necessary to trim the tapered end of the

abrasive strip so that it does not “bottom

out” against the inside of the drum.

Figure 14

IMPORTANT: Leave a gap – at least 1/8” –

between the tapered strip and the closed

end of the slot (Figure 15) to allow strip to

be pulled into the fastener as needed. If

necessary, trim the outside edge of the

abrasive strip.

12. Hold the abrasive in place with your left

hand, lift up the TUFTool and turn it

clockwise

while

maintaining

upward

pressure. Slowly move the TUFTool away

from you slightly, then down, while easing it

out of the hole. This releases the lever in its

proper position (Figure 16).

Figure 15

All abrasive strips will stretch in use and may

stretch enough to allow the take-up lever to

reach its lowest position so that it can not

maintain tension on the strip. If this occurs,

follow the above procedures to re-set the take-

up lever.

Always remove TUFTool from machine before

operating.

Grounding Instructions

Electrical connections must

qualified electrician in

be made by

compliance with all relevant codes. This

machine must be properly grounded to help

prevent electrical shock and possible fatal

injury.

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 tool is equipped with an electric cord

having an equipment-grounding conductor and a

grounding plug. The plug must be inserted into a

matching outlet that is properly installed and

grounded in accordance with all local codes and

ordinances.

Do not modify the plug provided. If it will not fit

the outlet, have the proper outlet installed by a

qualified electrician.

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.

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.

Repair or replace a damaged or worn cord

immediately.

As received from the factory, your drum sander

is intended for use on a 20 amp, 110V dedicated

circuit, which has an outlet and a plug that look

like the ones illustrated in Figure 17. A

temporary adapter, which looks like the adapter

illustrated in Figure 18, may be used to connect

this plug to a two-pole receptacle, as shown in

Figure 18, if a properly grounded outlet is not

available.

Figure 17

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 rigid

ear, lug, or tab, extending from the adapter,

must be connected to a permanent ground such

as a properly grounded outlet box, as shown in

Figure 18.

Adjustments

Drum Height Control

Figure 19

The drum height and depth of cut are controlled

by the height adjustment handle (see Figure 5).

Rotating the handle counterclockwise lowers the

drum, clockwise raises it. One revolution of the

handle will move the drum approximately 1/16”

(or 1/4 turn = approx. 1/64”).

Switch Lock

Unauthorized use of the sander can be

prevented by pulling out the key (Figure 20).

Press switch to OFF position before removing

the key. When the key is removed, the machine

can not be started.

To replace the key, slide it back into the switch

until it snaps.

Depth Gauge

The depth gauge indicates the distance between

the bottom of the sanding drum and the top of

the conveyor surface. Adjustment is performed

by “zeroing” the gauge.

Figure 20

1. Loosen screw (A, Figure 21) with a 9/16”

wrench sufficiently to allow indicator needle

(B) to be turned to depth gauge scale (C).

2. With an abrasive strip on the drum, lower

sanding drum to where it touches top of

conveyor belt.

3. At this drum position, the depth gauge

indicator needle (B) should align with the

zero mark of the scale. If it does not, loosen

screw (A) and raise or lower indicator

needle to align with zero on the scale.

4. Re-tighten screw (A).

Dust Cover Latch

The dust cover latch prevents the dust cover

from accidentally opening. To release the latch,

press inward on the dust cover knob (D, Figure

21). This will cause the dust cover center to flex

and release the latch. Note that the dust cover

latch can be adjusted in or out by loosening the

screw (E, Figure 21).

Conveyor Belt Tension/Tracking

Conveyor belt tension and tracking adjustments

may occasionally be necessary during break-in

and normal operation to compensate for belt

stretching.

Figure 21 (repeated)

IMPORTANT: The conveyor belt has been over-

tensioned for shipping purposes. It must be re-

tensioned before operating the sander.

Belt Tension: To adjust the tension of the

conveyor belt, first adjust the take-up screw nut

(Figure 22) on both sides of the conveyor to

obtain approximately equal tension on both

sides of the belt when taut.

Insufficient belt tension will cause slippage of

conveyor belt on the drive roller during sanding

operation. The conveyor belt is too loose if it can

be stopped by hand pressure applied directly to

the top of the conveyor belt.

Figure 22

Excessive belt tension can cause tracking

problems and result in bent rollers, bent take-up

brackets, and premature wearing of the bronze

roller bearings or conveyor belt.

Belt Tracking: Adjustments to tracking are

made while the conveyor belt is running. After

the proper belt tension has been achieved, turn

on the conveyor unit and set it at the fastest

speed setting. Watch for a tendency of the

conveyor belt to drift to one side of the

conveyor. If there is drifting, tighten the take-up

screw nut (Figure 22) on the side toward which

the belt is drifting, and loosen the take-up screw

nut on the opposite side. NOTE: Adjust the take-

up screw nuts only 1/4 turn at a time. Then allow

time for the belt to react to the adjustments

before proceeding further. Try to avoid over-

adjustments.

Conveyor Belt Replacement

1. To replace a worn conveyor belt, raise drum

to highest position. Unplug machine from

power source and unplug motor cord from

control box receptacle.

2. Adjust conveyor take-up screw nuts (Figure

22) to relieve belt tension.

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

3. Remove the four bolts attaching conveyor

assembly to base. Lift up and slide conveyor

out to the side of the machine.

4. Set conveyor on motor side and slide

conveyor belt off the end of the conveyor

bed.

5. Reverse process for installation of new belt.

Sanding Drum Alignment

The sanding drum must be aligned parallel to

the conveyor bed for proper machine operation.

The sanding drum comes preset from the

factory. If a problem with the drum alignment

occurs, follow the instructions below.

Figure 23

First inspect the alignment with a gauge of some

kind. The following procedure uses a steel

straight edge as a gauge.

1. Unplug sander from power source.

2. Open the dust cover and remove the

abrasive strip from the drum.

3. Insert the gauge between the drum and

conveyor bed at the outer end of the drum

(Figure 23). With the dust cover open, lower

sanding drum while slowly rotating drum by

hand until the drum lightly contacts the

thickness gauge.

Figure 24

4. Remove thickness gauge and place under

drum at the other end (Figure 24). If the

drum does not contact the thickness gauge

to the same degree as the opposite end of

the drum, alignment is necessary.

To align the drum:

1. Loosen the four 3/8” hex cap screws – two

front, two rear (A, Figure 25). This allows the

entire drum carriage and shroud to be

pivoted on two screws – one screw in front,

one in back.

2. Lay the thickness gauge under the drum

lengthwise (Figure 26). Rotate the fine tune

adjustment knob (B, Figure 25) until the

drum contacts the gauge equally along its

entire surface. Rotate the knob clockwise to

raise the outboard end of the drum,

counterclockwise to lower the outboard end

of the drum. Use the height adjustment

handle to raise or lower the entire drum.

3. When drum is parallel to conveyor, tighten

the four screws (A, Figure 25).

Fine-Tuning Drum Alignment

(for sanding boards wider than the drum)

NOTE: Perform this alignment after you are

familiar with sander operation. This is an

operational test.

When sanding boards wider than the drum,

drum alignment is critical and must be exactly

level to slightly high on the outboard end to

prevent ridges from forming on the board.

Always check this on a piece of scrap wood, as

follows, before sanding the work piece.

1. Test alignment with scrap wood roughly 6

inches wide and 20 to 30 inches long. Install

abrasive, turn on sander, and pass the

board through the sander sideways so that

the end of the board extends beyond the

end of the drum.

Figure 27

2. Without changing drum height, rotate the

board 180° and sand the same side.

3. If a ridge is visible where the drum overlaps,

loosen the four screws (A, Figure 27) and

raise the outboard end of drum by turning

the fine tune adjustment knob (B, Figure 27)

slightly clockwise. Re-tighten the four

screws.

4. Repeat process until the ridge is eliminated,

and the entire board is sanded.

NOTE: Keep track of how many revolutions of

the fine tune knob are needed to change drum

alignment for wider (over 16”) sanding. When

sanding narrow stock (less than 16”) loosen the

four screws (A, Figure 27) and turn fine tune

adjustment knob counterclockwise same

amount as initial wide sanding until drum is

again parallel.

Important: Only turn fine tune adjustment knob

when all four screws (A, Figure 27) are loose.

Drum Height Control Adjustment

If the height control mechanism does not

operate easily or smoothly, or there is excessive

vertical movement or deflection of the drum

carriage, perform the following adjustments:

1. With a 1/8” wrench, adjust all four studs by

tightening the lock nuts (Figure 28), then

loosening them 1/8 to 1/4 turn. If the lock

nuts are set too tight, height control will not

operate easily. If the lock nuts are too loose,

excessive deflection of the outboard end of

the drum carriage will result.

2. Apply lubricant to front and rear areas of

motor mount slide.

3. Push height adjustment handle (Figure 28)

downward to set firmly on housing.

Figure 28

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

4. Loosen set screws on collar (Figure 28).

5. Slide collar upward against housing so that

all vertical free-play of height adjustment

screw is eliminated. An easy method of

doing this is to use a block of wood on top of

the motor mount slide and under the collar,

while lowering the drum with the height

adjustment handle. Lubricate around

washers beneath handle and above collar.

Tension Roller Alignment

The infeed and outfeed rollers are tensioned to

provide downward pressure on the workpiece to

prevent slippage on the feed conveyor. Tension

rollers are set at the factory, but should be

inspected and may require adjustment as the

sander receives use.

Improperly adjusted tension

rollers (i.e. those set too high, rendering

them non-functional) could allow kick-back

of pieces being sanded.

1. Unplug sander from power source and

remove abrasive from drum.

2. Loosen all four hex nuts on the bearing bolts

(A, Figure 29). This will allow both tension

rollers to drop to their lowest position.

(NOTE: Figure 29 only shows outboard end

of drum. Adjustments must be made on both

ends of drum.)

3. Lower sanding drum to where it contacts the

conveyor bed. Then raise the sanding drum

by making 3/4 turn of the height adjustment

handle.

4. Tighten the four hex nuts (A, Figure 29).

Both tension rollers are now positioned

about 1/16” below the bottom of the sanding

drum.

Figure 29

Tension Roller Pressure Adjustment

You can increase or decrease tension roller

pressure by turning the screws on the tension

roller brackets (B, Figures 29 & 30).

Too much tension roller pressure can result in a

“snipe” mark, which is identified as a visible line

running across the width of the board and

located approximately 2-1/4” from the end of the

board.

If the snipe occurs on the leading end of the

board, adjust the outfeed tension roller. If the

snipe occurs on the trailing end of the board,

adjust the infeed tension roller.

Figure 30

Tension roller pressure can also be adjusted by

raising the height of the rollers, as follows:

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

lower the drum slightly more. However, a

combination of several variables will determine

the proper depth of cut to use, including the

following:

1. Repeat “Tension Roller Alignment” except

raise the sanding drum only 1/4 turn of the

height adjustment handle.

2. If both tension rollers are causing snipe then

tighten all four hex nuts (A, Figure 29) at this

position.

1. Abrasive type and grit size.

2. Width of the piece being processed.

3. Hardness of the piece.

3. If only outfeed tension roller causes snipe,

only tighten rear (outfeed) hex nuts on each

end of drum at this position, then raise

sanding drum another 3/4 turn of the handle.

4. Feed rate of the conveyor belt.

Establishing Proper Drum Height

1. To establish drum height, position the stock

to be sanded under the drum. Do NOT start

drum.

4. Press infeed tension roller down to rest on

conveyor bed and tighten front (infeed) hex

nuts at this position.

2. Lower the drum to the stock thickness,

making sure drum can be rotated by hand

while contacting stock.

This process sets the tension roller assembly at

an angle providing less tension pressure on the

outfeed roller.

Do not start drum while in

contact with stock!

Operation

Before using your drum sander, review the

previous pages in this manual on initial set-up

and adjustment. In this section, you will learn

how to operate the machine.

3. Without changing drum height, turn on

conveyor and run the stock out from under

the drum. Start sanding drum and sand

stock at that same position.

4. With the drum operating, feed stock under

the drum from the infeed side and against

the rotation of the drum. Always maintain

control of the stock to avoid kick-back and/or

slippage.

Circuit Breaker

The sander is equipped with a motor protective

device (circuit breaker). The breaker will

automatically shut the sander off when

excessive current is consumed.

NOTE: If motor heats up during operation, depth

of cut may be too great for size of grit and/or

feed rate may be too fast.

If the breaker is tripped, turn the sander off and

press the circuit breaker button on the motor to

re-set.

Tips for Maximum Performance

Basic Operating Procedure

The versatility designed into the 16-32 Plus

drum sander allows it to be used for a wide

variety of tasks that will boost the return on your

investment. For example, its capabilities range

from taking the place of a planer to thickness

rough stock, to speeding up fine sanding work

often done with slower, dust-generating hand

sanders.

1. Set depth of cut.

2. Start drum.

3. Start conveyor and select feed rate.

4. Start dust collection system.

5. Feed stock through machine.

Setting Depth of Cut

Learning how to use its adjustments and

controls will allow you to fine-tune the machine

for maximum results. The best results come

from experimenting with different abrasive grits

and machine adjustments to fit the job at hand.

Following is a list of useful tips which can help

you improve performance of your sander.

Adjusting the drum sander for the proper contact

between the abrasive and the stock determines

the mechanical depth of cut.

It may take some experimentation to determine

the proper depth of cut, given the variables of

abrasive grit, type of wood, and feed rate. For

best results, use scrap wood to practice sanding

and to develop skill and familiarity with the

machine before doing finish work.

Dust Collection

When connecting dust collectors, remember that

straight pipe will not restrict airflow as much as

flexible tubing. Y’s and elbows will restrict airflow

less than T’s. Also, a hose smaller than 2-1/2”

diameter should not be used.

A good rule of thumb when sanding with grits

finer than 80 is to lower the drum so it contacts

the workpiece but drum can still be rotated by

hand. When using grits coarser than 80, you can

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

there is room, angling the stock on the conveyor

belt can also help. Slowing the conveyor feed

when coming to a rail in the stock can help

prevent a dip or gouge. This allows the abrasive

to work the wider width with less effort, and to

achieve better consistency of the finished

surface.

Multiple-Piece Sanding Runs

When abrasive planing (or thickness sanding) a

run of similar pieces that you want to have the

same thickness, it is best to determine the

thickness of the thinnest piece and process all

pieces to that same thickness in one session. Be

aware that the sander will remove cups and

crowns in the workpiece; consider this when

measuring and processing stock to the same

thickness.

Stock Feeding Angle

Some pieces, because of their dimensions, will

need to be fed into the machine at a 90° angle

(perpendicular to the drums). However, even a

slight offset angle of the stock will provide for

more effective stock removal. The optimum

feeding angle for stock removal is about 60°

(see Figure 31).

Sanding Multiple Pieces At Once

When sanding multiple pieces simultaneously,

make sure to stagger (step) the pieces across

the width of the conveyor belt. This provides

better contact with the tension rollers. Try to

process only multiple pieces of similar thickness.

If there is a significant thickness difference, the

thinner pieces can slip on the conveyor belt if

they do not contact the tension rollers. Also note

that pieces thicker than 3/4” should be longer

than the minimum normally recommended to

prevent tipping of the stock.

Edge Sanding

When edge sanding, the sander will mimic the

opposite edge of the stock which is lying on the

conveyor belt. Because of this, it is important for

the stock edge to have been ripped at the proper

angle to the face before the sanding process.

When edge sanding stock that is less than 3/4”

wide or more than 2” high, it is good procedure

to stack and clamp several pieces together to

prevent them from slipping or tipping on the

conveyor belt.

Figure 31

Angling the workpiece for stock removal

provides other advantages, such as less loading

of certain areas of the drums due to glue lines or

mineral streaks in the stock, more even wear of

abrasive strips, potentially faster feed rates, and

lighter loads on the motor. Note that to get the

best final finish, however, the stock should be

fed through the machine so it will be sanded in

line with the grain of the wood on the final one or

two passes.

Sanding Imperfect Stock

When sanding stock with a cup or crown, place

the crown up. This will stabilize the stock to help

prevent tipping or rocking during sanding. (After

the crown has been removed and the top is flat,

turn the stock over and sand the opposite side.)

To avoid personal injury, take special care when

sanding stock that is twisted, bowed, or

otherwise varies in thickness from end to end. If

possible, support such stock as it is being

sanded to keep it from slipping or tipping. Use

extra roller stands, help from another person, or

hand pressure on the stock, to minimize

potentially hazardous situations.

Keeping the Machine Clean

For best results, make cleaning the machine a

regular shop procedure. Allowing excess build-

up of dust and debris can adversely affect

performance through the loading of the

abrasives, slippage on the conveyor table,

and/or the accumulation of material inside the

drums which can throw off the center of balance.

Leave the dust collector on when cleaning dust

from the drums. Also brush the conveyor belt

after cleaning operations. If not cleaned, the

conveyor belt could allow stock to slip during

sanding operations.

Face Frames and Raised Panel Doors

It is very important to have the proper abrasive

contact when doing this type of sanding. If the

machine is set to take an excessive depth of cut,

the result can be a gouge or dip as the drum

goes from sanding the rails at full width to

sanding just a few inches of width on the stiles.

To prevent this, make sure that when using

abrasives finer than 80 grit the drum is in contact

with the wood but can still be spun by hand. If

8. Install second Tracker opposite the first. Use

both Trackers unless the second one does

not fit in conveyor or if conveyor belt is

damaged.

Tracker Kit (98-0080)

Trackers dramatically reduce tracking adjust-

ments of conveyor belts. They are already

installed on your sander. The following

information is for re-setting or replacing your

trackers, should that become necessary. Refer

to Figure 32.

9. Turn conveyor bed right side up and re-

position the bed onto the base. Re-attach

the four mounting bolts and tighten.

Caution: Be careful not to knock Tracker(s)

out of conveyor bed when turning conveyor

over.

1. Disconnect power to sander, and disconnect

motor cord from control box receptacle.

10. Make sure all switches are off. Connect

power to sander and plug in motor.

2. Raise drum as far as it will go.

11. Tension conveyor belt using take-up screw

nuts. If both Trackers are installed, it is very

important to have equal tension on both

sides of the conveyor belt. Tighten both

sides of take-up screw nuts until equal

tension is obtained.

3. Loosen the conveyor take-up screw nuts to

relieve conveyor belt tension and slide

driven roller fully inward. Slide conveyor belt

to one side of bed.

4. Remove the four bolts holding the conveyor

table to the sander base.

12. To check tension, turn on conveyor full

speed and place both hands on conveyor. If

conveyor belt can be stopped, continue

tensioning until conveyor belt cannot be

stopped by both hands on the belt while the

conveyor is operating at full speed.

5. Lift conveyor bed and slide it out of the

sander. Turn conveyor bed upside down. Be

careful not to damage the conveyor belt.

6. On the underside of the conveyor bed, there

are U-channels welded to the bed. The

Tracker is positioned on the inside of the

first U-channel on the infeed side of sander

(the U-channel closest to the rubber covered

drive roller and gear motor). The back of the

Tracker is magnetized and will stick to the

side wall of the conveyor bed. Do not install

Tracker if the edge of the conveyor belt is

damaged or torn.

13. Make sure conveyor belt runs smoothly

inside Tracker slot and that magnet is

holding the Tracker in position.

14. Continue to watch tracking of conveyor and

adjust only if necessary, making sure to

keep equal tension on conveyor belt at all

times and not allowing conveyor belt to

buckle under conveyor bed.

7. With the first Tracker installed, slide the

conveyor belt into the bottom slot of the

Tracker. Note: When installed properly, only

the bottom lip of the Tracker will be visible.

The top slot is to be used if the bottom slot

wears out.

For fine work, such as furniture, try not to skip

any grit grades during the sanding process. In

general, premium quality abrasives will produce

a better finish with a less noticeable scratch

pattern.

Abrasives

The abrasive material you choose will have a

substantial effect on the performance of your

sander. Variations in paper type, weight, coating

and durability all contribute to achieving your

desired finish.

NOTE: Grits that are too fine can sometimes

burnish the wood and leave a glossy surface

which will not accept stains evenly. This will vary

by type of wood. Oak, for example, is

susceptible to burnishing because of its open

pores.

JET Abrasives are available in Ready-To-

Wrap^TMpre-cut lengths or in the convenient

Ready-To-Cut pre-marked box. Your JET dealer

can recommend the best choice for your

application.

Cleaning Abrasive Strips

Regularly clean the abrasive strips on the drums

with commercially available cleaning sticks,

following the manufacturer’s directions. Cleaning

sticks are available from your JET dealer. When

cleaning, also brush the stick crumbs from the

drum while it is still rotating.

Selecting Drum Abrasives

It is important to select the proper grit of

abrasives for the type of sanding being

performed to achieve maximum sanding results.

As with any sanding operation, first begin

sanding with a coarser grit, depending upon the

roughness of the stock or the amount of stock to

be removed. Then progressively work toward

finer grits. The chart (Figure 33) shows the

general uses for the various grits. JET offers

abrasives in the ten different grits shown –

consult the stock numbers on page 26 to order.

Always wear eye protection

while performing sandpaper cleaning, and

take all precautions to avoid any contact of

hands or clothing with uncovered rotating

drums.

Cloth-backed abrasives can be cleaned by

soaking in paint thinner or mineral spirits for 20

minutes to 1 hour, then using a brush to remove

any build-up or burns. Dry the abrasive strips

completely before using.

The amount of stock to be removed is a major

consideration when choosing the grit grade to

start with. Grits 24, 36, 50 and 60 are primarily

designed for stock removal. Grits 24 and 36 will

remove the most material in one pass, whether

you are doing abrasive planing, cleaning up

glued panels, or flattening stock. Grits from 100

through 220 are primarily finishing grits designed

to remove the scratch pattern from the previous

grit used. For best results, never skip more than

one grit grade when progressing through a

sanding sequence.

Increasing Abrasive Life

Abrasive life can be increased not only by

cleaning, but by removing the abrasive strip from

the drum and reversing it. To do this, remove the

strip and use what was the trailing end as the

starting end on the left (outboard) side of the

drum. Reversing the strip will provide a fresh set

of cutting edges on the abrasive.
