Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Changing the Tool
Wear protective gloves when changing tools. The drill

turn the front sleeve (10) in the rotational direction ➊ until
the tool can be inserted. Insert the tool.
Hold the rear sleeve (11) of the keyless chuck (9) and firmly
tighten the front sleeve (10) by hand in the rotational direc-

Changing the drill chuck
If your power tool does not have a drill spindle locking mech-
anism, you must have the drill chuck changed by an author-
ised after-sales service centre for Bosch power tools.
The drill chuck must be tightened using a tight-
ening torque of approx. 25–30 Nm.
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
u
easily ignite.
