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 insertion or
•
removal of the battery cartridge.
To remove the battery cartridge, withdraw it from
•
the tool while sliding the button on the front of the
cartridge.
To insert 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 part on the upper side of the button, it is not
locked completely. Insert it fully until the red part
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 inserting the battery
•
cartridge. If the cartridge does not slide in easily, it
is not being inserted correctly.
Setting for desired screw length

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.

rotation before the tool stops may damage the tool.
When not operating the tool, always set the
•
reversing switch lever to the neutral position.
