Installing or removing abrasive belt
Fig.3

Adjusting belt tracking
Fig.5
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
Fig.6
The use of the dust bag makes sanding operations clean
and dust collection easy. To attach the dust bag, fit it
onto the dust spout.
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.

OPERATION

Sanding operation
Fig.7
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.

Use a screwdriver to remove the brush holder caps.
Take out the worn carbon brushes, insert the new ones
and secure the brush holder caps.
