Dust/Chip Extraction

The dust from materials such as lead paint, minerals and
metal can be harmful to human health. Touching or breath-
ing in this dust can trigger allergic reactions and/or cause
respiratory illnesses in the user or in people in the near vicin-
ity.
Certain kinds of metal dust are hazardous, especially in com-
bination with alloys such as zinc, aluminium or chrome. Ma-
terials containing asbestos may only be machined by special-
ists.
– 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

u

Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
