Battery protection system
(Lithium-ion battery with star marking)
Fig.2
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.

Power switch action
WARNING:
•
Before inserting the battery cartridge in the
tool, always check to see that the switch
trigger actuates properly and returns to the
"OFF" position when released. Do not pull the
switch trigger hard without pressing in the
lock-off button. This can cause switch
breakage.
Operating a tool with a switch that does
not actuate properly can lead to loss of control and
serious personal injury.
Fig.4
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, move the lock-off button forward and
pull the switch trigger. Release the switch trigger to stop.
