3. Replace the warning labels if they become obscured or removed.  
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, 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 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. Steel toed shoes are recommended because heavy parts  
can fall off the conveyor table onto feet.  
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. 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.  
14. 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.  
15. 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  
function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting  
and any other conditions that may affect its operation. A guard or other part that is damaged should  
be properly repaired or replaced.  
16. Provide for adequate space surrounding work area and non-glare, overhead lighting.  
17. Keep the floor around the machine clean and free of scrap material, oil and grease.

3.0 Safety warnings  
19. Make your workshop child proof with padlocks, master switches or by removing starter keys.  
20. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are  
careless acts that can result in serious injury.  
21. Remove loose items and unnecessary work pieces from the area before starting the machine.  
22. Maintain a balanced stance at all times so that you do not fall or lean against the conveyor belt or  
other moving parts. Do not overreach or use excessive force to perform any machine operation.  
23. Keep hands clear while feeding workpieces onto the conveyor table. The workpiece will be forced  
down as it begins to feed into the machine, causing a pinching action between workpiece and  
conveyor table.  
24. Stand to one side of the conveyor table and do not let anyone else stand in line with the table while a  
workpiece is being fed through the machine.  
25. Do not attempt to sand stock shorter than 12 inches long without butting a board of equal thickness  
behind it to help it through the machine. Do not sand stock less than 1/8” thick.  
26. Never reach into a running machine. Turn off and disconnect from power source before attempting to  
retrieve parts from within the machine.  
27. 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.  
28. Use recommended accessories; improper accessories may be hazardous.  
29. 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.  
30. Do not stand on the machine. Serious injury could occur if the machine tips over.  
31. Never leave the machine running unattended. Turn the power off and do not leave the machine until  
all parts come to a complete stop.

7.0 Assembly  
The sander should be placed on a level, sturdy  
floor, preferably concrete, with plenty of space  
surrounding it for on- and off-loading of stock,  
and general maintenance work.  
Open the two lower side panels and use the  
leveling screws inside the cabinet (Figure 1) to  
level the sander. The machine can also be  
secured to the floor with high quality lag screws  
(not provided) through the four mounting holes  
inside the cabinet.  
Remove the protective coating from exposed  
metal surfaces with a soft cloth moistened with  
kerosene or a good commercial solvent. Do not  
use acetone, gasoline or lacquer thinner, as  
these have a low flash point and can be a fire  
hazard, as well as damage the paint finish. Do  
not get solvents on rubber or plastic areas of the  
machine.  
Figure 1  
7.1 Air Supply Connection  
The sander must be connected to an air supply  
unit. The recommended working pressure is 75  
to 80 PSI.  
The air connection is on the Filter/Regulator unit  
located at the back of the sander (Figure 2).  
Attach the incoming air supply to the connector  
with a flexible hose.  
The working pressure can be adjusted with the  
pressure regulator. Lift up on the adjustment  
knob and rotate it clockwise to increase air  
pressure, counterclockwise to decrease air  
pressure. When the desired pressure is shown  
on the pressure gauge, push down the  
adjustment knob to lock the setting.  
Figure 2  
7.2 Dust Collection  
Connect a dust collection system (not provided)  
to the dust ports atop the sander cabinet with 5”  
flexible hose and hose clamps. Make sure your  
dust collector has sufficient capacity for this  
machine.  
Always turn on the dust collector prior to  
operating the sander.

is damaged.  
Make sure the direction of  
the arrows on the inside of the sanding belt  
matches the rotation of the machine. See  
Figure 4.  
6. Install the new belt by placing it first over the  
upper roller, then over the free and contact  
rollers, and slide the belt all the way onto  
the rollers.  
Figure 3  
7. Center the belt while avoiding contact with  
the limit switch fingers that are located on  
each side of the belt.  
8. Re-install the spacer block (C, Figure 3) and  
lock screw (B, Figure 3) and tighten the lock  
screw by turning clockwise.  
9. Turn the air valve switch (A, Figure 3) to ON  
to tension the sanding belt.  
10. Make sure there is clearance between  
sanding belt edges and the limit switch  
fingers on either side. If there is not, make  
the appropriate corrections (with the air  
valve turned OFF).  
NOTE: The sander will not start if a limit  
switch is engaged.  
11. Before doing any sanding, the sanding belt  
should be tested for proper tracking and  
oscillation. See the appropriate sections in  
this manual.  
8.0 Electrical  
Figure 4  
8.1 Grounding Instructions  
Electrical connections must  
be made by  
a
qualified electrician in  
compliance with all relevant codes. This  
machine must be properly grounded while in  
use to help protect the operator from  
electrical shock and possible fatal injury.  
In the event of a malfunction or breakdown,  
grounding provides a path of least resistance for  
10  
Download from Www.Somanuals.com. All Manuals Search And Download.  
electric current to reduce the risk of electric  
shock to the operator.  
Improper connection of the equipment-  
grounding conductor can result in 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.  
The sander should be connected to a dedicated  
circuit with a minimum 100 Amp service. The  
sander has been factory wired to run at 230 volt  
operation. It can be converted to 460 volt if  
desired. See the appropriate sections below.  
8.2 230 Volt Operation  
The sander may be fitted with a 230 volt plug, or  
may be “hard-wired” directly to an electrical  
control panel. If hard-wired to a panel, make  
sure a disconnect is available for the  
operator.  
Refer to the diagram inside the sander’s  
electrical box for clarification of electrical  
connections. These diagrams are also shown in  
sections 17.0 and 18.0 of this manual.  
1. Make sure the machine’s plug is  
disconnected from the power source. If it will  
be hard-wired, make sure the fuses have  
been removed or the breakers have been  
tripped in the circuit to which the sander 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. Always follow proper Lock  
Out/Tag Out procedures when performing  
any wiring on this machine.  
2. Make sure the power source corresponds to  
the specifications of the sander as recorded  
on the sander’s motor plate.  
3. Open the sander’s electrical box and  
connect the three incoming power leads to  
the terminals marked R,S,T. See Figure 5.  
Connect the green ground wire to grounding  
terminal E.  
Figure 5  
(Model WB-25 shown)  
4. Connect the machine to power (or install the  
fuses or reset the breaker at the power  
source). The power light (see Figure 19)  
should now be lit.  
11

5. Press the Up S or Down T button on the  
keypad (see page 18 for detailed keypad  
instructions). Make sure the conveyor table  
moves in the same direction as indicated on  
the button.  
6. If the conveyor table moves in the wrong  
direction, turn off the machine and  
disconnect from power. Switch any two of  
the three incoming power leads at R,S,T.  
7. Re-connect power to the sander.  
8.3 460 Volt Conversion  
To convert the sander to 460V:  
1. Disconnect sander from power source.  
2. In the electrical cabinet, switch the “R” wire  
on the transformer from the 220V to the  
440V terminal. See Figure 6. (Refer to the  
wiring diagram on the inside cover of the  
electrical box for clarification.)  
3. Replace two 230V overload relays with two  
460V overload relays (not included; see  
parts list for stock numbers).  
Figure 6  
4. Change the wiring at the main motor, the  
conveyor table motor, and the table  
elevating motor, according to the wiring  
diagrams inside their respective junction  
boxes.  
5. If using a plug, install a UL/CSA-listed plug  
appropriate for 460V operation.  
8.4 Extension cords  
The use of an extension cord for this sander is  
discouraged, because of the machine’s high  
amperage draw. 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.  
9.0 Adjustments  
9.1 Sanding Belt Tracking and  
Oscillation  
The sanding belt should oscillate left and right  
without a tendency to slide off the rollers. If the  
sanding belt runs outside of the normal track, it  
will contact a limit switch and the machine will  
stop automatically.  
The oscillation settings have been made at the  
factory, but should be checked by the operator.  
NOTE: When a new sanding belt is installed,  
there may be a slight length tolerance between  
the right and left sides of the sanding belt which  
12  
Download from Www.Somanuals.com. All Manuals Search And Download.  
may result in incorrect tracking. If this occurs,  
the oscillation timing can be set to compensate.  
1. Adjust oscillation while the machine is  
running. Turn on the air valve switch and  
press the sanding belt start button (see  
Figure 19).  
2. The upper roller will pivot left and right. The  
duration of the sanding belt’s oscillation to  
the right side and to the left should be equal.  
For example, if the oscillation time to the  
right is one second, then the oscillation time  
to the left should also be one second.  
3. If the oscillation time to the right side is one  
second, but the oscillation time to the left  
side is longer, then loosen the tracking  
adjustment lever (rotate it counterclockwise)  
and move it to the left until proper timing is  
achieved. See Figure 7.  
Figure 7  
4. When finished, tighten the tracking  
adjustment lever.  
5. If the oscillation time to the left side is one  
second, but the oscillation time to the right  
side is longer, then loosen the tracking  
adjustment lever and move it to the right  
until proper timing is achieved. Tighten the  
tracking adjustment lever.  
9.2 Oscillation Air Flow  
For correct sanding belt oscillation, there must  
be adequate air flow through the holes of the  
oscillation bracket (Figure 8). When the sanding  
belt is operating, its edge will pass over the  
holes in the oscillation bracket. The blocked air  
flow will cause a sensor to activate the tracking  
cylinder, which pivots the upper roller and shifts  
the belt back out, causing it to leave the air flow.  
This process will continually repeat itself.  
Figure 8  
If there is inadequate air flow, the sanding belt  
will track too far and contact a limit switch.  
Adjust the air flow using the air flow control knob  
(Figure 9). Loosen the jam nut and rotate the  
knob clockwise to decrease air flow,  
counterclockwise to increase air flow. Tighten  
the jam nut to lock the setting.  
Frequently inspect the holes in the oscillation  
bracket – make sure they are clean and clear of  
obstructions.  
Figure 9  
9.3 Oscillation Speed  
To adjust the speed of the oscillation, loosen the  
jam nut on the speed control knob (Figure 9),  
then turn knob clockwise to decrease oscillation  
speed or counterclockwise to increase  
oscillation speed. When finished, tighten jam  
nut.

9.4 Platen Position  
The sander has a removable platen with a  
graphite strip and a felt pad to reduce friction  
against the sanding belt. Positioning of the  
platen depends upon the type of wood being  
used.  
The height of the platen is set at the factory, but  
can be re-adjusted by rotating the platen  
adjustment knob (Figure 10). Each mark on the  
scale indicates  
a
raising or lowering  
measurement of 0.005mm. One complete  
rotation of the scale moves the platen 0.2mm or  
approximately 8/1000 of an inch.  
Figure 10  
Theoretically, optimum finish sanding results are  
obtained when the bottom of the platen extends  
slightly below the bottom of the conveyor rollers.  
The main consideration in adjusting the platen is  
to make sure that both ends are symmetrical  
and level.  
NOTE: The platen must be kept clean. After  
sanding, if the workpiece has straight notches  
across it, the graphite and felt pad have worn  
out and should be replaced immediately.  
9.5 Replacing Graphite and Felt Pad  
To replace the graphite strip and felt pad,  
proceed as follows:  
1. Remove the lock screw (B, Figure 3) and  
the spacer block (C, Figure 3).  
2. Place the platen pull hook into the hole on  
the end of the platen and pull out the lower  
portion of the platen assembly, as shown in  
Figure 10. NOTE: The platen is tightly fitted  
and will require a firm pull with the pull hook.  
3. Note carefully how the current graphite and  
felt strip are mounted. Replace them with  
the new ones.  
4. Re-install the platen by aligning the end of it  
with the dovetail track on the fixed portion of  
the platen assembly, and push it all the way  
in using the pull hook.  
Figure 11  
5. Replace the spacer block and lock screw.  
9.6 V-Belt Tension and Replacement  
For the first few days of operation a new belt  
should be checked occasionally and adjusted for  
tension as necessary until the belt is properly  
“worn in.”  
The v-belts on the main motor and table  
elevating motor should be checked for proper  
tension.  
Tighten any of the v-belts as follows:  
Figure 12  
14  
Download from Www.Somanuals.com. All Manuals Search And Download.  
1. Disconnect sander from power source.  
2. Loosen the lower hex nut (A, Figure 11/12)  
on the motor base.  
3. Tighten the top hex nut (B, Figure 11/12) to  
lower the motor plate until proper tension is  
achieved.  
4. When the belt is properly tensioned, you  
should be able to push in the belt  
approximately 3/4” at a point midway  
between the pulleys using moderate finger  
pressure.  
5. Re-tighten the bottom hex nut (B, Figure  
11/12) against the bottom of the motor plate.  
If installing a new v-belt, use the hex nuts to  
raise the motor plate enough to remove the old  
belt and mount the new one.  
NOTE: When replacing v-belts on the main  
motor, replace the entire set of three  
simultaneously.  
9.7 Conveyor Belt Tension  
Check the tension of the conveyor belt on the  
infeed and outfeed rollers – the conveyor belt  
should be tight enough that you cannot shift it  
with your hands. If the conveyor belt needs  
tightening, proceed as follows.  
1. Disconnect sander from power source.  
2. Rotate the adjustment screws (the left one  
is shown in Figure 13) as needed with a  
19mm wrench. Rotate clockwise to increase  
tension, counter-clockwise to decrease  
tension. (NOTE: Removal of the emergency  
stop cover is not necessary for tensioning.)  
Figure 13  
NOTE: Do not over-tighten the screws as this  
will hasten wear of the conveyor belt.  
9.8 Conveyor Belt Tracking  
The conveyor belt should remain centered upon  
the rollers during operation. If it approaches to  
either the left or right side, adjustment is  
necessary.  
First check that the conveyor belt tension is  
correct. If the tension needs adjustment, do this  
first before you adjust the tracking (see  
“Conveyor Belt Tension”). Then proceed as  
follows.  
Conveyor belt tracking should be adjusted while  
the conveyor belt is running. Make adjustments  
in increments and allow the conveyor belt time  
to respond to each change.  
Keep hands away from the  
moving conveyor belt.  
15  
Download from Www.Somanuals.com. All Manuals Search And Download.  
1. Remove the four screws securing the  
emergency stop cover and remove the  
cover. See Figure 13. This will allow better  
inspection of the belt’s movement on the  
roller.  
2. Turn on the conveyor belt.  
3. Adjust tracking using the same adjustment  
screws that were used for tensioning in  
Figure 13.  
4. If the conveyor belt is moving to the right  
side, turn the right screw clockwise. This will  
return the tracking toward the left.  
5. If the conveyor belt is moving to the left  
side, turn the left screw clockwise. This will  
return the tracking toward the right.  
Figure 14  
6. A positioning wheel (Figure 14) has been  
provided on the right and left sides of the  
conveyor belt to limit the belt tracking. When  
adjusting the tracking, the conveyor belt  
should be moved until its edge just touches  
the positioning wheels.  
7. Allow the sander to run for several minutes  
while observing the conveyor belt tracking  
and readjust if necessary.  
8. Turn off the conveyor belt and re-install  
emergency stop cover.  
9.9 Feed Rate  
The feed rate is infinitely variable within the  
provided range, in order to meet the sanding  
requirements of a wide variety of materials.  
Selecting a proper feed rate is largely a matter  
of experience. In general, soft woods require a  
higher feed rate, while hard woods require a  
lower feed rate.  
Change the feed rate only  
while the conveyor belt is running. Failure to  
comply may cause damage to the gearbox.  
Figure 15  
Adjust the feed rate with the selector knob on  
the worm gear reducer (Figure 15). Turn the  
selector knob clockwise to decrease the  
conveyor belt speed, counterclockwise to  
increase it.  
9.10 Pressure Bar Adjustment  
The front and rear sets of pressure bars have  
been factory adjusted. This setting should,  
however, be checked before operating the  
sander.  
The pressure bars should be parallel to the  
conveyor table with equal pressure on each end,  
and are set slightly below the level of the  
sanding belt.  
16  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If the ends of the workpiece are sniped, the front  
pressure bars are too low. The pressure should  
be enough to firmly hold the workpiece against  
the conveyor, but not so hard that the ends of  
the workpiece spring up after clearing the bar.  
Also, if the ends of the bars are not exerting  
equal pressure, the workpiece will tend to move  
sideways on the conveyor during sanding.  
To raise or lower each set of pressure bars:  
1. Disconnect sander from power source.  
2. The sanding belt should be installed, and  
the air valve turned ON.  
3. Place a sanded panel with even thickness  
on the conveyor table and under the  
pressure bars. The panel should be long  
enough to contact both front and back sets  
of pressure bars.  
Figure 16  
4. Raise the table manually using the  
handwheel (Figure 16) until the panel  
contacts the pressure bars.  
5. Make sure the pressure at the right and left  
side of pressure bars is even.  
6. If adjustment is needed, release the lock nut  
(A, Figure 17) with a 14mm wrench.  
7. Insert the adjusting tool (B, Figure 17) into a  
hole in the adjusting knob. Rotate the  
adjusting knob clockwise to raise that side  
of the pressure bar, counterclockwise to  
lower it.  
Figure 17  
8. When finished, re-tighten lock nut (A, Figure  
17).  
9.11 Table Parallelism  
Parallelism of the conveyor table to the contact  
roller has been factory-set and should not  
require further adjustment. However, as the  
machine receives extended use, this setting  
should be checked.  
Inspect parallelism by one of two methods:  
1. Use a sanded board of equal thickness.  
Pass the board several times through the  
machine  
at  
a
sanding  
depth  
of  
approximately 1/64”, then measure the  
thickness of the board at different points  
along the edges with calipers. If excessive  
variation occurs, the table needs adjusting.  
OR, remove the sanding belt and place a  
gauge of some kind at one side of the  
conveyor table and below the contact roller.  
Raise the table manually using the  
handwheel until the gauge just touches the  
contact roller. Repeat at the other side of  
the table and compare the gauge readings.  
17  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If the readings are different, the table needs  
adjusting.  
2. Disconnect sander from power source.  
3. At the area of the table that needs  
adjustment, loosen the two screws (A,  
Figure 18) on the bracket of the elevation  
screw, and rotate the bracket as needed.  
(The elevation screw is protected by the  
dust guard bellow.) Turn the elevating screw  
clockwise to lower the table in that area,  
counterclockwise to raise the table (see  
Figure 18).  
IMPORTANT: Turn both elevating screws at  
one side of the table an equal amount, in  
order to maintain front-to-back parallelism  
with the rollers.  
Figure 18  
4. Tighten screws (A, Figure 18).  
5. Re-connect sander to power, and make  
further  
test  
runs.  
Make  
additional  
adjustments as needed, with the machine  
disconnected from power.  
10.0 Operating Controls  
Figure 19 shows the control panel functions.  
The emergency stop button shuts down all  
machine operations. The button remains  
engaged after being pushed. To disengage,  
rotate the ring until the emergency stop button  
pops back out.  
The emergency stop cover has a plate (shown  
in Figure 16) which shuts down all machine  
operations when it is pushed.  
10.1 Amperage Meter  
The amperage meter (Figure 19) continually  
monitors the load upon the sander. To avoid  
tripping of the circuit breaker and the overload  
relays, reduce the load immediately when the  
amperage meter indicates excessive amperage  
pull.  
Figure 19  
10.2 LED Controller and Keypad  
The controller is used for precise positioning of  
the conveyor table based upon the workpiece  
thickness and your desired sanding depth.  
Figure 20 shows the key features of the unit.  
The LED control unit comes  
pre-programmed from the factory. Do NOT  
alter the specifications of your control unit  
without authorization from WMH Tool Group.  
Incorrect programming of the device could  
cause unit failure as well as risk of injury to  
people and damage to the sander.

10.2.1 Calibration  
To establish the distance between conveyor  
table and sanding belt, proceed as follows:  
1. Connect power and air to the sander, and  
turn the air valve switch on to tighten the  
sanding belt. NOTE: The controller will not  
move the table if the air valve switch is off.  
2. Press and hold the UP S button on the  
keypad to raise the conveyor table until the  
thicknesser knob (Figure 21) contacts the  
limit switch. The table will automatically stop  
while making slight contact with the sanding  
belt.  
Figure 21  
3. Press “0” (zero) on the keypad (the display  
will begin flashing and the input light will be  
lit). Then press SET for 2 to 3 seconds. The  
display will now read zero. This is the  
distance between sanding belt and conveyor  
table, upon which further movement of the  
table can be based.  
4. Press the sanding belt START button and  
the conveyor table START button on the  
control panel, and feed the workpiece  
through the machine.  
5. Make further passes as needed, raising the  
table each time using the UPS button.  
4. Input a number using the keypad (display  
will begin flashing and the input light will be  
illuminated).  
11.0 Operation  
Before operating the sander, make sure that:  
5. While the display is still flashing, press the  
START button on the keypad (run light will  
now be illuminated). The conveyor table will  
move to the desired distance from the  
sanding belt.  
1. The dust collection system is turned on.  
2. Sanding belt tracking and oscillation are  
working properly.  
3. Conveyor belt tracking is correct.  
4. All screws and handles are tightened  
securely.

automatically sets the table at the thickness of  
your workpiece:  
1. Place your workpiece upon the conveyor  
table and move it below the thicknesser, as  
shown in Figure 21. Keep the workpiece flat  
upon the table. Press and hold the UP S  
button on the keypad to raise the conveyor  
table. When the workpiece contacts the limit  
switch the conveyor table will stop. The table  
is now positioned at the thickness of your  
workpiece.  
6. Thickness is correctly input into the LED  
unit.  
7. Feed rate is correctly set.  
8. Workpiece is free of nails, knots and other  
obstructions.

If the sanding belt breaks, all movement will be  
stopped, though the conveyor table can still be  
raised or lowered.  
The water should be removed daily from inside  
the filter cups. On the filter/regulator at the back  
of the cabinet, press the drain cock (see Figure  
2). On the filter inside the cabinet, unscrew the  
cup to empty it.  
Once the machine has stopped, the operator  
should find where the braking system was  
tripped, and make the necessary adjustments.  
The machine can then be re-set and started.  
The oil inside the gear reducer should be  
replaced after the first 100 work hours and every  
2500 work hours thereafter. Recommended oil is  
#90 gear oil. Pour oil into the filler hole until the  
level is above the dot on the sight glass. See  
Figure 22.  
12.0 Maintenance  
Before  
doing  
any  
maintenance on the sander, disconnect it  
from the electrical supply by pulling out the  
plug or switching off the main switch.  
Failure to comply may cause serious injury.  
The interior of the machine should be thoroughly  
cleaned each day after using the sander.  
Remove the sanding belt before cleaning and  
re-install it when finished.  
Keep the sanding belt clean using cleaning  
sticks or pads (not provided).  
Blow dust off the conveyor belt with compressed  
air or use a dust collector vacuum attachment.  
The bearings should be greased after every 150  
work hours.
