Dust/Chip Extraction

Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.

Position for chiselling
In the "chiselling" position, the impact rate

ity when chiselling.

and keep it pressed.
To switch off the machine, release the On/Off
switch 5.

To start the machine, press the On/Off switch 5
at the top (I) until it locks.
To switch off the machine, press the On/Off
switch 5 at the bottom (0) and release it.
For low temperatures, the power tool reaches
the full hammer/impact capacity only after a cer-
tain time.
Setting the Speed/Impact Rate

and impact preselection in accordance with the
material to be worked.
