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
