Battery protection system
Lithium-ion battery with star marking
► Fig.2: 1. Star marking
Lithium-ion batteries with a star marking 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:
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. In this situation, remove and recharge
the battery.
