OPERATING INSTRUCTIONS
Installing or removing wheel point (Fig.1&2)
Important:
•
Always be sure that the tool is switched off and
unplugged before installing or removing the 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 from the collet nut. Exceeding this distance
could cause vibration or a broken shaft.
To remove the wheel point, follow the installation
procedure in reverse.
CAUTION:
Use the correct size collet cone for the wheel point
which you intend to use.
Switch action (Fig. 3)
CAUTION:
Before plugging in the tool, always check to see that
the switch actuates properly and returns to the ‘‘OFF’’
position when the side of the switch lever is
depressed.
To start the tool, slide the switch lever toward the ‘‘I’’
position. For continuous operation, press the front of
the switch lever to lock it. To stop the tool, press the
rear of the switch lever, then slide it toward the ‘‘O’’
position.
Speed adjusting dial (Fig. 4)
The tool speed can be infinitely adjusted by turning
the speed adjusting dial, which is marked 1 to 5.
Higher speed is obtained when the dial is turned in the
direction of number 5; lower speed is obtained when
it is turned in the direction of number 1.
Refer to the table below for the relationship between
the number settings on the adjusting dial and the
approx. tool speed.

3 – 4 17,000 – 24,000 4,100 – 5,800
4 – 5 24,000 – 28,000 5,800 – 7,000
CAUTION:
•
If the tool is operated continuously at low speeds for
a long time, the motor will get overloaded and
heated up.
•
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.
Operation (Fig. 5)
Turn the tool on without the wheel point making any
contact 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 pressure
on the tool will only cause a poor finish and overload-
ing of the motor.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
