with pliers. Always use
the combination wrench.

Insert the combination
wrench as shown in the fig-
ure.

Approved abrasive

tools

You can use all the abrasive tools mentioned in these operat-
ing instructions.
The permissible speed [min

-1

] or the circumferential speed

[m/s] of the abrasive tools used must at least match the val-
ues given in the table.
It is therefore important to observe the permissible 

rota-

tional/circumferential speed

 on the label of the abrasive

tool.

Rotating the machine head

u

Pull the plug out of the socket before carrying out any
work on the power tool.

The machine head can be
rotated in 90° increments.
In this way, the on/off
switch can be brought into
a more favourable handling
position for particular ap-
plications, e.g. for left-
handed tool users.
Completely unscrew the
four screws. Rotate the ma-
chine head carefully,

without removing it from the housing

, into the new posi-

tion. Screw in and retighten the four screws.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity. 
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-

terial wherever possible.

– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.

u

Avoid dust accumulation at the workplace. 

Dust can

easily ignite.

Operation

Start-up

u

Pay attention to the mains voltage. The voltage of the
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.

When operating the power tool using a mobile generator that
does not have sufficient reserve capacity or an adequate
voltage control system with inrush current boost converter,
loss of performance or atypical behaviour may occur upon
switch-on.
Please check the suitability of the power generator you are
using, particularly with regard to the mains voltage and fre-
quency.

u

Products that are only sold in AUS and NZ:

 Use a resid-

ual current device (RCD) with a nominal residual current
of 30 mA or less.

u

Hold the tool by the insulated gripping surfaces and
auxiliary handle only.

The application tool could come

into contact with hidden wiring or its own cord.

 Con-

tact with live wires may make metal parts of the tool live,
posing a risk of electric shock.
