Sanding operation
004232
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.
Clamps (optional accessory)
This machine can be operated in the inverted position. To do so, secure the
004140
machine to a stable workbench with two clamps.
CAUTION:
• Always be sure that the tool is switched off and unplugged before
attempting to perform inspection or maintenance.
