The main handle (31) can be rotated 90° to the left or right
relative to the motor housing. This enables the on/off switch
to be brought into a more convenient position for particular
working situations, such as cutting operations using the ex-
traction guard for cutting with a guide block (21) or for left-
handed persons.
Pull back the handle release (32) in the direction of the ar-
row while simultaneously turning the main handle (31) until
it clicks into the required position.

Pull the plug out of the socket before carrying out any
u
work on the power tool.
The machine head can be ro-
tated in 90° increments. This
enables the on/off switch to
be brought into a more con-
venient position for particular
working situations, such as
cutting operations using the
extraction guard for cutting
with a guide block (21) or for
left-handed persons.
Completely unscrew the four screws. Rotate the machine
head carefully, without removing it from the housing, into
the new position. 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.
