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.
CAUTION:
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)
► Fig.3: 1. Star marking
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 bat-
tery 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.
OPERATING

the tool, ensure that the Switch is at the "O" posi-
tion and the Switch is off.
CAUTION:
Push the Lock Button and ensure
that the Button comes up when it is released.
If the Lock Button will not come up when it is
released, the Tipped Saw will be prevented from
rotating when the tool is operated resulting in
damage to parts and the motor to burn out.

tion and ensure it stays there and does not move.
Then push down on the rear of the Switch to
