CAUTION:
• Always switch off the tool before installing or
removing of the battery cartridge.
• Hold the tool and the battery cartridge firmly
when installing or removing battery cartridge.
Failure to hold the tool and the battery cartridge
firmly may cause them to slip off your hands and
result in damage to the tool and battery cartridge
and a personal injury.
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Insert it all the way until it locks in place with
a little click. If you can see the red indicator on the upper
side of the button, it is not locked completely.
CAUTION:
• Always install the battery cartridge fully until the
red indicator cannot be seen. If not, it may
accidentally fall out of the tool, causing injury to
you or someone around you.
• Do not install the battery cartridge forcibly. If the
cartridge does not slide in easily, it is not being
inserted correctly.
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.
