Installing or removing battery cartridge
CAUTION:
Hold the tool and the battery cartridge firmly
•

•
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 part on the upper side of the button, it
is not locked completely. Insert it fully until the red
part 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 inserting the battery
•
cartridge. If the cartridge does not slide in easily, it
is not being inserted correctly.
Battery protection system
The battery cartridge is equipped with the protection
system, which automatically cuts off the output power for
its long service life.
The tool may stop during operation when the tool and/or
battery are placed under the following situation. This is
caused by the activation of protection system and does
not show the tool trouble.

At this time, release the switch trigger and
remove causes of overload and then pull the
switch trigger again to restart. When the tool
does not work even after pulling the switch
trigger, the battery power auto-stop is still at
work. Charge the battery cartridge before
use.
When the remaining battery capacity becomes low:
•
Recharge the battery cartridge.
