Battery protection system
The tool is equipped with a battery protection system.
This system automatically cuts off power to the motor to
extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are 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.
