CAUTION:
• When installing the belt, make sure that the direction of the arrow on the
back of the belt corresponds to the one on the tool itself.

Adjusting belt tracking

003381
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
003386
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
2
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 collec-
tion.
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. Exces-
sive pressure may cause stalling, overheating of the motor, burning of the
workpiece and possible kickback.
