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 trigger switch on
the tool and stop the application that caused
the tool to become overloaded. Then pull the
trigger switch again to restart.
If the tool does not start, the battery is
overheated. In this situation, let the battery
cool before pulling the trigger switch 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.

NOTE:
When the LED display goes off, the tool is turned
•
off to save the battery power. To check the
remaining battery capacity, slightly pull the switch
trigger.
The LED display goes off approximately one
•
minute after releasing the switch trigger.
When the tool is overheated, the light flashes for
•
one minute, and then the LED display goes off. In
this case, cool down the tool before operating
again.
When the LED display lights up and the tool stops
•
even with a recharged battery cartridge, cool down
the tool fully. If the status will not change, stop
using and have the tool repaired by a Makita local
service center.
