FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before adjusting or
checking function on the tool.
Installing or removing battery cartridge
CAUTION:
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.
Fig.1
Always switch off the tool before installing or
•
removing of the battery cartridge.
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. Always 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. Install it 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 use force when installing the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
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 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.
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.
Fig.3
For your safety, this tool is equipped with a dual
switching system. To turn on the tool, press the lock-off
button and triggers A and B. Release either one of the
two pressed triggers to turn off. The sequence of
switching is unimportant as the tool only starts when
both switches are activated.
Indication lamp
Fig.4
Running the tool allows the indication lamp to show the
battery cartridge capacity status.
When the tool is also overloaded and has stopped
during operation, the lamp lights up in red.
Refer to the following table for the status and action to
be taken for the indication lamp.
