Installing or removing wheel (Fig. 3 & 4)
To remove the wheel, insert one hex wrench into the end
of the spindle and another hex wrench into the end of the
output shaft. Turn the hex wrench in the output shaft
clockwise while securely holding the hex wrench in the
spindle so that the wheel cannot revolve. Pull the output
shaft out from the wheel. Move the wheel slightly away
from the spindle and remove the wheel from the tool.
NOTE:
• The output shaft has a left hand thread.
To install the wheel, follow the removal procedures in
reverse. When installing it, be sure to align the notches in
the wheel with the pins on the spindle.
Connecting to dust collector (Fig. 5)
The use of a dust collector makes sanding operations
clean and dust collection easy. To connect a dust collec-
tor, open the dust port by sliding the cover plate up and in
a clockwise direction. Attach the joint onto the dust port.
Now a dust collector can be connected to this tool.
CAUTION:
• When not using a dust collector, close the dust port
opening with the cover plate.
OPERATION ( 6)
Fig.
Hold the tool firmly with both hands on the handle and
the grip in front. Place the tool on the workpiece surface
and move the tool gently forward and backward while
applying slight downward pressure.
CAUTION:
• The tool should not be in contact with the workpiece
surface when you turn the tool on or off. Damage to the
tool or the workpiece surface and injury to the operator
may result.
• Apply slight downward pressure only. Excessive pres-
sure may decrease tool efficiency, shorten wheel ser-
vice life and possibly gouge the workpiece surface.

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. 7)
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. 8)
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:
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).
