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 manufacturer 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
The pressure control valve allows full adjustment of water quantity and pressure. The
safety valve protects the machine from excessive pressure and cannot be adjusted
beyond the admissible operating pressure. The setting nuts are sealed with lacquer.
Replacements, repairs, new adjustments and sealing operations may
only be performed by trained personnel.
Adjustment of pressure, quantity and temperature
The operating pressure, the water flow
and correspondingly the water
temperature ist controlled by the pressure
control valve.
A right-hand turn increases the pressure, a
left-hand turn decreases the pressure.
