Tips for maintaining maximum battery life
1. Charge the battery cartridge before
completely discharged.
Always stop tool operation and charge the
battery cartridge when you notice less tool
power.
2. Never recharge a fully charged battery
cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room
temperature at 10 ﾟC - 40 ﾟC (50 ﾟF - 104 ﾟF).
Let a hot battery cartridge cool down before
charging it.
4. Charge the battery cartridge once in every six
months if you do not use it for a long period of
time.

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
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 (Battery cartridge
with a star mark)
Fig.2
The battery cartridge with a star mark is equipped with
the protection system, which automatically cuts off the
output power for its long service life.
The tool stops 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.
• When the tool is overloaded:
At this time, release the switch trigger,
remove the battery cartridge and remove
causes of overload and then pull the switch
trigger again to restart.
• When battery cells get hot:
If any operation of the switch trigger, the
motor will remain stopped. At this time, stop
use of the tool and cool or charge the battery
cartridge after removing it from the tool.
• When the remaining battery capacity gets low:
If any operation of the switch trigger, the
motor will remain stopped. At this time,
remove the battery cartridge from the tool
and charge it .
