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 car-
tridge. Overcharging shortens the battery
service life.
3.
Charge the battery cartridge with room tem-
perature at 10 °C - 40 °C (50 °F - 104 °F). Let
a hot battery cartridge cool down before
charging it.
4.
When not using the battery cartridge, remove
it from the tool or the charger.
5.
Charge the battery cartridge if you do not use
it for a long period (more than six months).

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 as
shown in the figure, 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.
Indicating the remaining battery
capacity

ambient temperature, the indication may differ slightly
from the actual capacity.
NOTE: The first (far left) indicator lamp will blink when
the battery protection system works.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life. The tool will auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:
Overload protection
When the tool/battery is operated in a manner that
causes it to draw an abnormally high current, the tool
automatically stops. In this situation, turn the tool off
and stop the application that caused the tool to become
overloaded. Then turn the tool on to restart.
Overheat protection
When the tool/battery is overheated, the tool stops
automatically. Let the tool cool down before turning the
tool on again.
Overdischarge protection
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
