Tips for maintaining maximum
battery life
Charge the battery cartridge before completely dis-
1.
charged. Always stop tool operation and charge the
battery cartridge when you notice less tool power.
Never recharge a fully charged battery cartridge.
2.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tempera-
ture 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

CAUTION:
• Always be sure that the tool is switched off and
the battery cartridge is removed before adjust-
ing or checking function on the tool.
Installing or removing battery cartridge
► Fig.1: 1. Red indicator 2. Button 3. Battery cartridge
• 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 car-
tridge. 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: 1. Star marking
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 trigger switch on the tool
and stop the application that caused the tool to become
overloaded. Then pull the trigger switch again to restart.
If the tool does not start, the battery is over-
heated. In this situation, let the battery cool
before pulling the trigger switch 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 the indicator
► Fig.3: 1. Indicator lamps 2. Check button
Press the check button on the battery cartridge to indi-
cate the remaining battery capacity. The indicator lamps
light up for a few seconds.

NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
Setting for desired screw length
► Fig.4: 1. Lever 2. Stopper base 3. Label on feeder
box 4. Fenestella
There are 7 positive-lock screw length settings. To
obtain the desired setting, pull out the stopper base
while depressing the lever until you see the number
of the desired screw length (indicated on the label on
feeder box) appear to rest in the fenestella of stopper
base. See the table below for the relation between the
number indicated on the label on feeder box and the
