Working Advice

Changing the Chiselling Position (Vario-Lock)
The chisel can be turned to 36 positions. In this
manner, the optimum working position can be
selected for each application.
– Insert the chisel into the tool holder.
– Set the mode selector switch 12 to the
"Vario-Lock" position. (see Setting the Oper-
ating Mode, pag 24)
– Turn the tool holder to the desired chiselling
position.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
Clean the tool holder 5 each time after using.
Keep the drill chuck mounting free from dust.
Lubrication is not necessary.
WARNING! Important instructions for con-
necting a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to
the following code:
Do not connect the blue or brown wire to the
earth terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it
must be disposed of safely.
