in the figure and press down to retract the front pulley so
that you can slip the other end of the belt over the rear
pulley. When pressing down the tool, be careful not to
allow the front pulley to turn unexpectedly, causing you to
lose control of the tool.
NOTE:
• The arrow on the inside of the belt and that marked
on the rear pulley must point in the same direction.

OPERATION
CAUTION:
• Secure the workpiece with clamps, etc. if there is
any possibility of it moving during the work opera-
tions.
• The tool should not already be in contact with the
workpiece surface when you turn the tool on or off.
Otherwise a poor sanding finish, damage to the belt
of loss of control of the tool may result.
• When working with the tool, be very careful to avoid
any contact of the tool and belt with any part of your
body or anyone or anything near you.
Hold the tool firmly with both hands. Turn the tool on and
wait until it attains full speed. Gently apply the tool to the
workpiece surface and move the tool forward and back.
Press the belt only lightly on the workpiece. Excessive
pressure may damage the belt and shorten tool life.

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