tween the tip of the drill bit and the tip of the

Changing the Tool

tightening torque of approx. 35–40 Nm.
Observe correct mains voltage! The voltage
of the power 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.
Actuate the rotational direction switch 7 on-
ly when the machine is at a standstill.
