10 – 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) above the
operating switch.
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.
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!
HI/LO switching (11)
With the HI/LO switch, two different
speed ranges can be selected.
• Switch position
LO
: 0–380 rpm for
turning screws in and out
• Switch position
HI
: 0–1260 rpm for
screw-driving and drilling
The speed range to be selected is
determined by the respective material
and the planned activity, and is to be
determined through work on a
specimen.
CAUTION! Carry out changeover
with motor stopped only.
11 – Maintenance and
environmental
protection
Clean the case only with a damp cloth –
Do not use solvents! Then dry well. To
maintain capacity, we recommend
completely discharging and recharging
the battery every two months. Store
only fully charged batteries. They should
therefore be recharged from time to
time. The place of storage must be dry;
the ambient temperature must not fall
below 0 °C or rise above 50 °C.
