ASSEMBLY AND OPERATING

SANDING

Clamp or otherwise secure your workpiece to 

prevent it from moving under the sander while 

being sanded. Secure the workpiece in a vice 

if possible.

WARNING: 

Any unsecured workpiece could 

be thrown toward the operator causing injury.
Place the sander on the workpiece so the 

complete sanding disc surface is in contact 

with the workpiece. Turn the sander ON by 

pressing on the left-hand side of the ON/

OFF switch. Move the sander slowly over the 

workpiece making successive passes in parallel 

lines, circles or crosswise movements. Because 

the random orbital motion of the sanding disc 

moves in tiny circles, it is not necessary to move 

the sander with the grain or in the same direction 

for successive passes (Fig. 6).
Upon completion of the sanding operation, turn 

sander OFF by pressing on the right-hand side 

of the ON/OFF switch. Wait until the sanding 

disc comes to a complete stop before removing 

it from the workpiece.

WARNING:

 Your sander should only be turned 

ON when the entire surface of the sanding disc

is in contact with the workpiece.  Failure to follow 

this sanding procedure could result in a loose 

sanding disc, which could result in possible injury.

CLEAN THE DUST BAG OFTEN

Clean the dust bag often. It will be more efficient 

when it is not clogged with sanding dust. To 

clean the dust bag, see Fig. 5 on Page 12.

NOTE:

Hold the sander with one 

hand on the hand grip (1) on top of 

the sander (Fig. 7). Be careful NOT to 

cover the cooling vents (2) with your 

hand. Covering the cooling vents could 

cause the motor to be damaged by 

overheating.

DO NOT FORCE THE SANDER. 

The weight of the sander usually provides adequate pressure. Let the sander and the sanding 

disc do the work. Applying added pressure will slow the motor, increase the wear on the 

sandpaper and greatly reduce the sander speed. Excessive pressure will overload the motor 

causing possible damage from the motor overheating. It will also create an inferior finish on 

sanded work. Any finish or resin on wood will soften from the frictional heat, causing sandpaper 

to become clogged quickly. Do not sand in one spot too long as the sander’s rapid action may 

remove too much material, making the surface uneven.
Extended periods of sanding may tend to overheat the motor. If this occurs, turn the sander

 OFF, wait until the sanding disc comes to a complete stop and remove it from the workpiece. 

Check to make sure your hands have not been covering the cooling vents. Let the motor cool 

before continuing the sanding operation.
