CAUTION:
•If the tool is operated continuously at low speeds for
a long time, the motor will get overloaded, resulting
in tool malfunction.
•The speed adjusting dial can be turned only as far
as 5 and back to 1. Do not force it past 5 or 1, or the
speed adjusting function may no longer work.

ASSEMBLY

CAUTION:
•Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.

Installing the side handle

Always use the side handle to ensure operating safety.
Install the side handle on the tool barrel, then tighten the
handle by turning clockwise at the desired position.

Installing or removing wheel point

Loosen the collet nut and insert the wheel point into the
collet nut. Use the smaller wrench to hold the spindle and
the larger one to tighten the collet nut securely.
The wheel point should not be mounted more than 8 mm
(5/16”) from the collet nut. Exceeding this distance could
cause vibration or a broken shaft.
To remove the wheel point, follow the installation proce-
dure in reverse.
CAUTION:
•A 1/4” collet cone is provided as standard equip-
ment. Use an optional collet cone 1/8” to install a 1/
8” shank wheel point.

OPERATION

Turn the tool on without the wheel point making any con-
tact with the workpiece and wait until the wheel point
attains full speed. Then apply the wheel point to the
workpiece gently. To obtain a good finish, move the tool
in the leftward direction slowly.
CAUTION:
•Apply light pressure on the tool. Excessive pres-
sure on the tool will only cause a poor finish and
overloading of the motor.

MAINTENANCE

CAUTION:
•Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by Mak-
ita Authorized or Factory Service Centers, always using
Makita replacement parts.
