6. BELT CENTERING CONTROL
WARNING! Wear eye protection before
carrying out a belt centering adjustment.
Turn the machine upside down, hold it firmly
with one hand, start the motor and release the
switch immediately after observing tracking of
sanding belt. If abrasive belt runs outward, turn
tracking adjustment knob counter-clockwise
and clockwise if belt runs inward (See Fig. F).
Adjust the belt until the outer edge of the belt is
even with the outer edge of the base-plate (11).
Belt life will be greatly increased by keeping the
tracking adjustment set properly.

WORKING HINTS FOR
YOUR BELT SANDER
If your power tool becomes too hot, especially
when used at low speed, set the speed to
maximum and run with no load for 2-3 minutes
to cool the motor. Avoid prolonged usage at very
low speed. Always use a sanding belt suited to
the material you wish to sand. Always ensure the
work-piece is firmly held or clamped to prevent
movement. Support large panels close to the
sanding area. Any movement of the material may
affect the quality of the sanding finish. Start your
sander before sanding and turn off only after
stopping sanding. For best results sand wood in
the direction of the grain. Do not start sanding
without the sanding belt fitted. Empty the dust
bag every 5 minutes or sooner to ensure efficient
dust collection.
