Battery protection system (Battery cartridge with
a star mark) (Fig. 2)
The battery cartridge with a star mark is equipped with
the protection system, which automatically cuts off the
output power for its long service life.
The tool stops during operation when the tool and/or bat-
tery are placed under the following situation. This is
caused by the activation of protection system and does
not show the tool trouble.
• When the tool is overloaded:
At this time, release the switch trigger, remove the bat-
tery cartridge and remove causes of overload and then
pull the switch trigger again to restart.
• When battery cells get hot:
If any operation of the switch trigger, the motor will
remain stopped.
At this time, stop use of the tool and cool or charge the
battery cartridge after removing it from the tool.
• When the remaining battery capacity gets low:
If any operation of the switch trigger, the motor will
remain stopped.
At this time, remove the battery cartridge from the tool
and charge it.

Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The light automatically goes out 10 – 15 seconds after
the switch trigger is released.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
Reversing switch action (Fig. 6)
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for counter-
clockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• When not operating the tool, always set the reversing
switch lever to the neutral position.
