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 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
overheated. 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.
Setting for desired screw length
Fig.3
There are 3 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 plate) appear
to rest on the very top edge of the casing.
See the table below for the relation between the number
indicated on the plate and the respective screw length
ranges.

Adjusting the driving depth
Depress the stopper base as far as it will go. While
keeping it in this position, turn the adjusting knob until
the bit tip projects approx. 5 mm from the stopper base.
Drive a trial screw. If the screw head projects above the
driving surface, turn the adjusting knob in the A
direction; if the screw head is countersunk, turn the
adjusting knob in the B direction.

Switch action
Fig.5
CAUTION:
Before inserting the battery cartridge into the tool,
•
always check to see that the switch trigger
actuates properly and returns to the "OFF"
position when released.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
Reversing switch action
Fig.6
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the
A side for clockwise rotation or from the B side for
counterclockwise rotation.
When the reversing switch lever is in the neutral
position, the switch trigger cannot be pulled.
CAUTION:
Always check the direction of rotation before
•
operation.
Use the reversing switch only after the tool comes
•
to a complete stop. Changing the direction of
rotation before the tool stops may damage the tool.
When not operating the tool, always set the
•
reversing switch lever to the neutral position.
