Safety Clutch

If the tool insert becomes caught or
jammed, the drive to the drill spindle is in-
terrupted.
Because of the forces that occur, always hold
the power tool firmly with both hands and
provide for a secure stance.
If the drilling tool jams, switch the machine off and
loosen the drilling tool. When switching the ma-
chine on with the drilling tool jammed, high reac-
tion torques can occur!
Changing the Chiselling Position
(Vario-lock)
The chisel can be locked in 12 positions. In this
manner, the optimum working position can be set
for each application.
Insert the chisel in the tool holder.
Turn the mode selector switch 3 to "Changing
the chiselling position" (Vario-lock).
Turn the tool holder to the desired chiselling posi-
tion.
Allow the mode selector switch 3 to latch in the
"Chiselling" position. The tool holder is locked in
this position.
The mode selector switch 3 must always be
locked in the "Chiselling" position when chis-
elling.
