7. Initial Operation

Before plugging in the device, check to see
that the rated mains voltage and mains
frequency, as specified on the rating label, match
your power supply.
Always install an RCD with a maximum trip
current of 30 mA upstream.
To guarantee secure purchase of the chuck:
After initial drilling (clockwise), use a screw-
driver to firmly tighten the safety screw inside the
drill chuck (if available/depending on the model).
THE SAFETY SCREW HAS A LEFT-HANDED
THREAD!

8.4 Selecting gear
Change thumbwheel (1) only when the
machine is in the process of running down
(briefly switch it on and off).
8.5 Setting impulse function
= impulse function switched on constantly (to
facilitate tightening and releasing of screws
that are tight even when the screw heads are
damaged. To enable clean drilling without
centre punching in tiles, aluminium or other
materials).
8.6 Preselecting rotational speed
See the table for recommended rotational speeds
for drilling.
