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°C - 40°C (50°F - 104°F). Let a hot
battery cartridge cool down before charging it.
4. Charge the battery cartridge if you do not use it for
a long period (more than six months).

FUNCTIONAL DESCRIPTION

WARNING:
• Always be sure that the tool is switched off and the
battery cartridge is removed before adjusting or
checking function on the tool. Failure to switch off
and remove the battery cartridge may result in serious
personal injury from accidental start-up.
Installing or removing battery cartridge
(Fig. 5)
CAUTION:
• Always switch off the tool before installing or removing
of the battery cartridge.
14
• Hold the tool and the battery cartridge 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.
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.
• Do not install the battery cartridge forcibly. If the
cartridge does not slide in easily, it is not being inserted
correctly.
NOTE:
• The tool does not work with only one battery cartridge.
Tool/battery protection system
The tool is equipped with a tool/battery protection system.
This system automatically cuts off power to the motor to
extend tool and battery life.
The tool will automatically stop during operation if the tool
or battery are placed under one of the following
conditions. In some conditions, the indicators light up.
Overload protection
When the tool is operated in a manner that causes it to
draw an abnormally high current, the tool automatically
stops and battery indicators blink. 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 for tool (Fig. 6)
When the tool is overheated, the tool stops automatically
and the power indicator blinks about 60 seconds. In this
situation, let the tool cool before turning the tool on again.
Overheat protection for battery
When the battery is overheated, the tool stops
automatically and the battery indicators light up. The tool
does not start even if pulling the switch trigger. In this
situation, let the battery cool before turning the tool on
again.
NOTE:
The battery overheat protection works only with a battery
cartridge with a star marking. (Fig. 7)
Overdischarge protection
When the battery capacity becomes low, the tool stops
automatically. If the product does not operate even when
the switches are operated, remove the batteries from the
tool and charge the batteries.
Indicating the remaining battery capacity
(Only for battery cartridges with "B" at the end of the
model number.) (Fig. 8)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for few seconds.
