Battery protection system
The tool and battery are equipped with a protection
system. This system automatically cuts off power to the
tool 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:

it to draw an abnormally high current.
In this situation, release the switch trigger on
the tool and stop the application that caused
the tool to become overloaded. Then pull the
switch trigger again to restart.
If the tool does not start, the battery is
overheated. In this situation, let the battery
cool before pulling the switch trigger again.
Low battery voltage:
•
The remaining battery capacity is too low and
the tool will not operate. In this situation,
remove and recharge the battery.
