Switch on the tool and make sure that the belt is aligned
properly. If the edge of the belt extends beyond the edge
of the steel plate or the edge of the belt retracts more
than 8 mm (5/16") away from the edge of the steel plate,
use the adjusting screw to adjust the belt tracking.
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 com-
ing 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 par-
ticles adhering to the insides which might hamper further
collection.

more efficient and cleaner operations can be
performed.
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 ade-
quate 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.
Replacing carbon brushes
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
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.
