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 allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
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 ma-
terials to be worked.

Avoid dust accumulation at the workplace.

Dust can

easily ignite.

lithium-ion batteries with the

voltage stated on the type plate of your power tool.

Using other batteries can lead to injuries and pose a fire
hazard.

(8)

to the middle posi-

tion to avoid unintentionally switching it on.

– Slide the battery

(10)

Adjusting the Speed/Impact Rate

– Adjust the speed/impact rate of the power tool when it is

on by pressing in the on/off switch

(9)

to varying extents.

Applying light pressure to the on/off switch

(9)

results in a

low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
