While the belt is running, use the adjusting knob to
center the belt tracking. Failure to do so can result in
frayed belt edges and wear on the sander frame.
Dust bag

Attach the dust bag onto the dust spout. The dust spout
is tapered. When attaching the dust bag, push it onto the
dust spout firmly as far as it will go to prevent it from
coming off during operation.
When the dust bag is about half full, remove the dust
bag from the tool and pull the fastener out. Empty the
dust bag of its contents, tapping it lightly so as to remove
particles adhering to the insides which might hamper
further collection.

For greater sanding efficiency and to help the belt run
cooler, install an optional carbon plate on the steel plate
when sanding hardwood or steel.
OPERATION
Sanding operation
CAUTION:
The tool should not be in contact with the
workpiece surface when you turn the tool on or off.
Otherwise a poor sanding finish or damage of the
belt may result.
Hold the tool firmly with both hands. Turn the tool on and
wait until it attains full speed. Then gently place the tool
on the workpiece surface. Keep the belt flush with the
workpiece at all times and move the tool back and forth.
Never force the tool. The weight of the tool applies
adequate pressure. Excessive pressure may cause
stalling, overheating of the motor, burning of the
workpiece and possible kickback.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
