HOW TO USE THE BELT SANDER
1. How to adjust sanding position.
Push switch and turn sanding belt te check position.
Adjust sanding belt so that both edges protrude
1.6mm – 3mm past edges of pulleys.
lf sanding belt is operated too far on the inside,
it may ceuse abrasion and damage machine.
Adjust sanding belt position by turning adjust screw.
(Fig. 3)
Turn adjust screw clockwise to move belt in.
Turn adjust screw counterclockwise to move belt
out.
CAUTION:
If sanding belt moves during operation, adjustment
can be made while in operation.
2. To turn on switch
Turn on switch while holding machine away from
surface to be worked on. If machine is placed on
surface when switch is pushed, surface may be
badly scratched.
The same applies when stopping the machine.
3. How to hold machine
Grasp handle and handle knob and hold machine
against surface to be worked on so that it contacts
surface lightly.
Weight of machine itself is sufficient for sanding
and polishing at highest efficiency.
Do not apply any additional pressure, for this would
place unnecessary load on motor, shorten life of
sanding belt and lower work efficiency.(Fig. 4)
4. How to move machine
Move mechine forward first and then backward,
repeating this motion.(Fig. 4)
5. How to select proper sanding belt
Choose sanding belt of proper grain size and grain
type for your specific purpose, by referring to Table
1 below.

CAUTION:
Sanding belt grain should be coarser than sandpaper
used for manual work.
Use sanding belt of same grain size until uniform
surface is obtained. Changing grain sizes may result
in poor finish.
6. How to operate switch
The power switch is turned ON when the trigger
is pulled, and if the stopper is once depressed, the
power switch becomes locked, allowing continuous
operation.
The stopper can be released pulling the trigger.

MAINTENANCE AND INSPECTION

1. Inspecting the sanding belt
Since continued use of a worn-out sanding belt will
degrade efficiency, replace the sanding belt as soon
as excessive abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
