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.

Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.

the like. Discoloration, deformation or cracks may
result.
