can loosen it by hand by
turning the knurled ring an-
ticlockwise. 

Never loosen a

tight quick-clamping nut
with pliers. Always use
the combination wrench.

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

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.
