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).

FUNCTIONAL DESCRIPTION
The battery
may have
malfunctioned.
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before adjusting or checking function on the tool.

from the actual capacity.
Installing or removing battery
cartridge
Tool / battery protection system
CAUTION: Always switch off the tool before
installing or removing of the battery cartridge.
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
CAUTION: Hold the tool and the battery car-
tridge 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.

To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
When the tool/battery is operated in a manner that
causes it to draw an abnormally high current, the tool
automatically stops without any indication. In this sit-
uation, turn the tool off and stop the application that
caused the tool to become overloaded. Then turn the
tool on to restart.
Overheat protection
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.
When the tool/battery is overheated, the tool stops automati-
cally. Let the tool cool down before turning the tool on again.
Overdischarge protection
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.
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
CAUTION: Do not install the battery cartridge
forcibly. If the cartridge does not slide in easily, it is
not being inserted correctly.
Releasing protection lock
When the protection system works repeatedly, the tool is locked.
In this situation, the tool does not start even if turning
the tool off and on. To release the protection lock,
remove the battery, set it to the battery charger and wait
until the charging finishes.
