Starting and stopping
Caution! Risk of over winding
caused by screwing screws in
too deep. Watch the screwing
process carefully and, if necessary,
stop early and finish the process with
an ordinary screwdriver. Always
practise first!
• Starting:
Press the ON/OFF switch (3): The
screwing process will start. Press and
keep the switch during the screwing
process.
• Stopping:
As soon as the screw has been
screwed in or removed fully, release the
On/Off switch.
9 – Mode of operation
Electronic rotation speed regulation
Using the electronic rotation speed
regulation (3), you can adapt the
rotation speed continuously to the
respective job.
• Light pressure on the switch (3) =
low rotation speed, in order to loosen
stuck bolts.
• Switch pressed hard = highest
possible rotation speed, for boring.
CAUTION! Avoid the motor
coming to a standstill under
loading when boring or screw-
driving!

Clockwise/anti-clockwise run
You determine the rotation direction
with the aid of the slide switch (4)

PLEASE NOTE! Change rotation
direction only with motor
stopped!
• Screw-driving in bolts: Slide switch
to Position R.
• Turning off bolts: Slide switch to
Position L.
• Safety position: Switch middle
position; in this position of the slide
switch the device cannot be put into
operation, e.g. in case of work
breaks, bit or drill change.
Torque setting
The drill screwdriver has a 16-stage
torque setting (2) in order to avoid
damage to the bolt or drilling heads.
By rotating the head on your drill
screwdriver, you can adjust the stage
necessary in each case, from 1 (easily
turned screw) to max. (stiff screw-
driving/drilling
). Always select the
torque most favourable for the
respective work.
