NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
NOTE: The first (far left) indicator lamp will blink when
the battery protection system works.
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 battery is operated in a manner that causes
it to draw an abnormally high current, the tool automat-
ically stops without any indication. 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 or battery is overheated, the tool stops
automatically. In this case, let the tool and battery cool
before turning the tool on again.
NOTE: When the tool is overheated, the lamp blinks.

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.
Protections against other causes
Protection system is also designed for other causes
that could damage the tool and allows the tool to stop
automatically. Take all the following steps to clear the
causes, when the tool has been brought to a temporary
halt or stop in operation.
1. Turn the tool off, and then turn it on again to
restart.
