Rotating the Machine Head (GWS 18V-... C)
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
The machine head can be
rotated with respect to
the machine housing in
90° steps. In this man-
ner, the On/Off switch
can be brought into a
more convenient position
for special working situa-
tions, e.g. for left-handed
persons.
Completely unscrew the
four screws. Rotate the
machine head carefully, without removing it from the hous-
ing, to the new position. Screw in and tighten the four screws
again.
Dust/Chip Extraction
 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dust can cause
1 609 92A 47F | (14.11.17)
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.
