ambient temperature, the indication may differ slightly

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:
Overloaded:
The tool is operated in a manner that causes it to draw
an abnormally high current. 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.
If the tool does not start, the battery is overheated. In this
situation, let the battery cool before turning the tool on again.
Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. If you turn the tool on, the motor runs
again but stops soon. In this situation, remove and
recharge the battery.
