To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Insert it all the way until it locks in place
with a little click. If you can see the red indicator as
shown in the figure, it is not locked completely.
CAUTION:
Always install the battery cartridge
fully until the red indicator cannot be seen. If not,
it may accidentally fall out of the tool, causing injury to
you or someone around you.
CAUTION:
Do not install the battery cartridge
forcibly. If the cartridge does not slide in easily, it is
not being inserted correctly.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life.
The tool will automatically stop during operation if the tool
or battery are placed under one of the following condi-
tions. In some conditions, the indication lamp lights up.

Overload protection
When the tool is operated in a manner that causes it to draw
an abnormally high current, the tool stops automatically and
the indicator lights up for about 60 seconds. 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.
Overheat protection
When the tool/battery is overheated, the tool stops automati-
cally and the battery indicator lights up for about 60 seconds.
The tool does not start even if you turn the tool on. In this
situation, let the battery cool before turning the tool on again.
Overdischarge protection
When the remaining battery capacity gets low, the
indicator blinks. By further use, the tool stops and the
indicator lights up for about 60 seconds. If you turn the
tool on, the motor runs again but stops soon. In this
situation, charge the battery cartridge.
NOTE: The timing, at which the lamp lights up,
depends on the temperature at work place and the
battery cartridge conditions.
