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 auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:

Overload protection

When the tool or battery is operated in a manner that
causes it to draw an abnormally high current, the tool
automatically stops without any indication. In this sit-
uation, 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 or battery is overheated, the tool stops
automatically. In this case, let the tool and battery cool
before turning the tool on again.

Overdischarge protection

When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
