Adjusting belt tracking
► Fig.4: 1. Adjusting knob
While the belt is running, use the adjusting knob to cen-
ter the belt tracking. Failure to do so can result in frayed
belt edges and wear on the sander frame.
Dust bag
► Fig.5: 1. Dust bag 2. Dust spout
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.

OPERATION

Sanding operation
CAUTION:
• The tool should not be in contact with the work-
piece 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 ade-
quate pressure. Excessive pressure may cause stalling,
overheating of the motor, burning of the workpiece and
possible kickback.
