OPERATION

CAUTION:
• Secure the workpiece with clamps, etc. if there
is any possibility of it moving during the work
operations.
• 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, dam-
age to the belt or 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.
Always use the side grip (auxiliary handle) and firmly
hold the tool by both side grip and switch handle during
operations. 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 dam-
age the belt and shorten tool life.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
Replacing carbon brushes
► Fig.8: 1. Limit mark
Remove and check the carbon brushes regularly.
Replace them when they are worn 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.
