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 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.

Operation

Starting Operation



Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the 
nameplate of the machine. Power tools marked with 
230 V can also be operated with 220 V.

Reversing the rotational direction (see figures H – I)

The rotational direction switch 

3

 is used to reverse the rota-

tional direction of the machine. However, this is not possible 
with the On/Off switch 

5

 actuated.

Right rotation:

 For drilling and screwing in screws, push the 

rotational direction switch 

3

 toward the left.

Left rotation:

 For loosening and unscrewing screws and 

nuts, push the rotational direction switch 

3

 toward the right.

Setting the operating mode

Drilling and Screwdriving

Set the selector switch 

2

 to the “Drilling” symbol.

Gear selection, mechanical



The gear selector 8 can be actuated at standstill or 
when the machine is running. However, this should not 
be done while operating at full load or maximum speed.

Two speed ranges can be preselected with the gear selector 

8

.

Gear 1:

Low speed range; for working with a large drilling diameter or 
for screwdriving.

Gear 2:

High speed range; for working with a small drilling diameter.
