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.
