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
•
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
cartridge. 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 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 respective
screw length.

Adjusting the driving depth
Fig.4
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 surface
of the workpiece, turn the adjusting knob in the "A"
direction; if the screw head is counter-sunk, turn the
adjusting knob in the "B" direction.
