Battery protection system (Lithium-ion
battery with star marking)
1
012128
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, 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.
Switch action
CAUTION:
Before inserting the battery cartridge into the tool,
•
always check to see that the switch trigger
actuates properly and returns to the "OFF"
position when released.
