Light pressure on the On/Off switch 6 results in low speed/im-
pact rate. Further pressure on the switch increases the
speed/impact rate.
Safety Clutch
If the tool insert becomes caught or jammed, the drive
to the drill spindle is interrupted. Because of the forces
that occur, always hold the power tool firmly with both
hands and provide for a secure stance.
If the power tool jams, switch the machine off and loos-
en the tool insert. When switching the machine on with
the drilling tool jammed, high reaction torques can oc-
cur.
Working Advice
Before any work on the machine itself, pull the mains
plug.
Changing the Chiselling Position (Vario-Lock)
The chisel can be locked in 36 positions. In this manner, the
optimum working position can be set for each application.
–Insert the chisel into the tool holder.
–Turn the mode selector switch
8
to the “Vario-Lock” posi-
tion (see “Setting the Operating Mode”).
–Turn the tool holder to the desired chiselling position.
–Turn the mode selector switch
8
to the “chiselling” posi-
tion. The tool holder is now locked.
–For chiselling, set the rotation direction to right rotation.
