ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.

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.
Operation
Starting Operation
u
Wear protective gloves when changing tools. The drill
chuck may heat up significantly when it is used for long
periods.
Avoid dust accumulation at the workplace. Dust can
easily ignite.
The drill chuck must be tightened using a tight-
ening torque of approx. 30–35 Nm.
Pay attention to the mains voltage. The voltage of the
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
