Dust bag (Fig. 5 & 6)
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 com-
ing 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 par-
ticles 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 per-
formed.
Carbon plate (Fig. 7)
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 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 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 inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes
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.
(Fig. 8)
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. (Fig. 9)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.

Noise
The typical A-weighted noise level determined according
to EN62841-2-4:
Sound pressure level (L
Sound power level (L
Uncertainty (K): 3 dB (A)
NOTE:
• The declared noise emission value(s) has been mea-
sured in accordance with a standard test method and
may be used for comparing one tool with another.
• The declared noise emission value(s) may also be
used in a preliminary assessment of exposure.
WARNING:
• Wear ear protection.
• The noise emission during actual use of the power
tool can differ from the declared value(s) depend-
ing on the ways in which the tool is used especially
what kind of workpiece is processed.
• Be sure to identify safety measures to protect the
operator that are based on an estimation of expo-
sure in the actual conditions of use (taking account
of all parts of the operating cycle such as the times
when the tool is switched off and when it is running
idle in addition to the trigger time).
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN62841-2-4:
Work mode: sanding metal plate
Vibration emission (a
Uncertainty (K): 1.5 m/s
NOTE:
• The declared vibration total value(s) has been mea-
sured in accordance with a standard test method and
may be used for comparing one tool with another.
• The declared vibration total value(s) may also be used
in a preliminary assessment of exposure.
