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. 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

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)
CAUTION:
• Always switch off the tool before installing or removing
of the battery cartridge.
• 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.
Battery protection system (Lithium-ion
battery with star marking) (Fig. 2)
Lithium-ion batteries with a star marking are equipped
with a protection system. This system automatically cuts
off power to the tool to extend battery life.
The tool will automatically stop during operation if the tool
and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes it to
draw an abnormally high current.
In this situation, release the switch lever/trigger on
the tool and stop the application that caused the tool
8
to become overloaded. Then pull the switch lever/
trigger again to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
switch lever/trigger again.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. In this situation, remove and
recharge the battery.
Indicating the remaining battery capacity
(Only for battery cartridges with "B" at the end of the
model number.) (Fig. 3)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for few seconds.

NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
Switch action
CAUTION:
• Before installing the battery cartridge into the tool,
always check to see that the switch lever/trigger
actuates properly and returns to the "OFF" position
when released. (Fig. 4)
To prevent the switch lever/trigger from accidentally
pulled, the lock-off lever/button are provided.
To start the tool, pull either switch lever or trigger.
• For the switch lever, pull the lock-off lever and then pull
the switch lever to start the tool.
• For the switch trigger, depress the lock-off button and
then pull the switch trigger to start to the tool. The lock-
off button can be pressed from either right or left.
The tool speed is increased by increasing pressure on the
switch lever/trigger. Release the switch lever/trigger to
stop.
