Battery protection system
The tool is equipped with a battery protection system.
This system automatically cuts off power to the motor to
extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes it to
draw an abnormally high current.
In this situation, turn the tool off and stop the
application that caused the tool to become
overloaded. Then turn the tool on to restart.
If the tool does not start, the battery is overheated.
In this situation, let the battery cool before turning
the tool on again.
• Low battery voltage:
The remaining battery capacity is too low and the
tool will not operate. In this situation, remove and
recharge the battery.
NOTE:
• The overheat protection works only with a battery
cartridge with a star marking. (Fig. 2)

always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
Reversing switch action (Fig. 5)
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.
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
counterclockwise rotation.
When the reversing switch lever is in the neutral
position, the switch trigger cannot be pulled.
Lighting up the lamp(s) (Fig. 6)
CAUTION:
• Do not look in the light or see the source of light directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp automatically goes out 10 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.
