Caution
Dry running of more than 2 min-
utes leads to damage of the

몇 Danger
The water jet that is emitted from
the high-pressure nozzle results
in a repulsion power acting on
the hand spray gun. Make sure
that you have a firm footing and
are also holding the hand spray
gun and spray lance/ extension
firmly.
High-pressure jets can be dan-
gerous if improperly used. The
jet may not be directed at per-
sons, animals, live electrical
equipment or at the appliance it-
self.
