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 particles adhering to the insides which might
hamper further collection.

For greater sanding efficiency and to help the belt run
cooler, install an optional carbon plate on the steel plate
when sanding hardwood or steel.
Connecting to Makita vacuum
cleaner
Cleaner sanding operations can be performed by con-
necting the belt sander to Makita vacuum cleaner.
When connecting to Makita vacuum cleaner, an optional
hose 28 mm in inner diameter is necessary.
OPERATION

Sanding operation

CAUTION:
• The tool should not be in contact with the work-
piece 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 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.
