High pressure hose and spraying device
Thehighpressurehoseandsprayingdevicesuppliedwiththemachinearemadeofhigh
gradematerial,theyarealsooptimizedforthemachineandmarkedasrequiredbythe
appropriateregulations.
If replacement parts are required, only such parts that are authorized by the manufactu-
rer and which bear the markings required by the appropriate regulations may be used.
The high pressure hose and spray device must be connected in a pressure-tight
manner.
The high pressure hose may not be driven over, pulled excessively, or twisted. The
hose may under no circumstances be pulled over sharp edges, since otherwise the
guarantee is automatically void.
Hoses are wearing parts. The guarantee only covers defects of fabrication no
external damages whatsoever.
Defective high-pressure hoses and spraying devices may not be repaired. They
always have to be replaced.
Pressure control valve-safety valve

Replacements, repairs, new adjustments and sealing operations may
only be performed by trained personnel.

Replacements and inspection work should only be performed by
qualified persons when the machine is disconnected from the power
supply, i.e. with plug pulled out from the electrical socket.
