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 over-
heated. 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 mark.

• Depending on the conditions of use and the
ambient temperature, the indication may differ
slightly from the actual capacity.
Indication lamp with multi function
► 1. Indication lamp
Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with
the slide switch positioned in the "O (OFF)" position, the
indication lamp flickers quickly for approximately one
second. If it does not flicker so, the battery cartridge or
indication lamp has broken.
— Overload protection
— When the tool is overloaded, the indication
lamp lights up. When the load on the tool is
reduced, the lamp goes out.
— If the tool continues to be overloaded and the indi-
cation lamp continues to light up for approximately
two seconds, the tool stops. This prevents the
motor and its related parts from being damaged.
— In this case, to start the tool again, move the
slide switch to the "O (OFF)" position once
and then to the "I (ON)" position.
— Battery cartridge replacing signal
— When the remaining battery capacity gets
small, the indicator lamp lights up during
operation earlier than enough capacity bat-
tery use.
