When the remaining battery capacity gets low,
the indicator lamp lights up during operation
signaling that it is time to change the battery.

Accidental re-start preventive function
−
Even if the battery cartridge is inserted on the
tool with the slide switch in the "I (ON)"
position, the tool does not start. At this time,
the lamp flickers slowly and this shows that
the accidental re-start preventive function is at
work.

To start the tool, first slide the slide switch
toward the "O (OFF)" position and then slide it
toward the "I (ON)" position.

Loosen the collet nut and insert the wheel point into the
collet nut. Use one wrench to hold the spindle and the
other 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
procedure in reverse.
8 mm (5/16") Max.

OPERATION
011478
Turn the tool on without the wheel point making any
contact with the workpiece and wait until the wheel point
reaches maximum 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 overloading of the motor.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may
result.
