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 car-
tridge 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 on the upper side of the button, 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.
NOTE: The tool does not work with only one battery cartridge.
NOTE: Pay attention to the position of your fingers when install-
ing the battery. The button will be depressed unintentionally.
Tool / battery protection system
The tool is equipped with a tool/battery protection system. 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 is placed under one of the following conditions.

Overload protection

When the tool is operated in a manner that causes it to
draw an abnormally high current, the tool automatically
stops and the main power lamp will blink. 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 is overheated, the tool automatically stops and
the capacity indicator lamp will blink as illustrated. In this situ-
ation, let the tool cool down before turning the tool on again.
