Switch on the tool and make sure that the belt is aligned
properly. If the edge of the belt extends beyond the
edge of the steel plate or the edge of the belt retracts
more than 8 mm away from the edge of the steel plate,
use the adjusting screw to adjust the belt tracking.
Dust bag
► Fig.5: 1. Dust spout 2. Dust bag
Attach the dust bag onto the dust spout. The dust spout
is tapered. When attaching the dust bag, push it onto
the dust spout firmly as far as it will go to prevent it from
coming off during operation.
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.
NOTE:
• If you connect a Makita vacuum cleaner to this
tool, more efficient and cleaner operations can
be performed.

OPERATION

Sanding operation

► Fig.7
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.
Clamps (optional accessory)
This machine can be operated in the inverted position.
To do so, secure the machine to a stable workbench
with two clamps.

unplugged before attempting to perform inspec-
tion or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized or Factory Service Centers, always
