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 / GFCI 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!
7.1 Fitting the additional handle (2)
B
For safety reasons, always use the additional
handle supplied.
Tighten the additional handle firmly by turning it.
8. Use

Impact drilling and normal drilling only in a
clockwise direction.
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).

The ratchet sound which can possibly be heard
after opening the drill chuck is functional and is
switched off by a reverse rotation of the sleeve.
If the chuck is very tightly closed: Firmly grip the
chuck with an open-end spanner at the chuck head
and firmly turn the sleeve in the direction of the
arrow -1.
Clamping the tool
- Insert the tool -2- as far as possible.
- Using one hand, hold the retainer ring securely
(depending on fittings).
- Turn sleeve in direction -3- until the noticeable
mechanical resistance has been overcome.
- Caution! The tool is not yet fully tightened!
Keep turning the sleeve (it must "click" when
turning) until it cannot be turned any further - only
now is the tool safely clamped.
With a soft tool shank, retightening may be required
after a short period of operation.
