Water and cleaning system
Water can be connected at mains pressure (1-10 bar pre-pressure) to the high pressure
pump or it can be sucked directly from a storage tank. The water is then forced under
pressure by the high pressure pump to the lance. The high pressure jet is formed by the
nozzle at the end of the lance.
Environmental, refuse disposal and water protection
regulations must be observed!
Lance with spray gun
The machine can only be operated when the safety trigger is squeezed. When the
lever is squeezed, the spray gun opens. The liquid is then pumped to the nozzle. The
spray pressure increases and quickly reaches the selected operating pressure. When
the trigger is released, the trigger gun closes and any further spraying of liquid from the
lance is stopped. The pressure gauge must show 0 bar.
The increase in pressure when the trigger gun is closed causes the pressure control
valve-safety valve to open. The motor is switched off by the pressure switch. When
the trigger gun is opened, the pressure control valve - safety valve closes, the motor
is started and the pump resumes pressure spraying from the lance with the selected
operating pressure.
The spray gun is a safety device. Repairs should only
be performed by qualified persons. Should replacement
parts be required, use only components authorized by the
manufacturer.
Pressure control valve - safety valve
The pressure control valve - safety valve protects the machine from a build up of
excess pressure, and is designed not to permit an excess pressure to be selected for
operation. The limit nut on the handle is sealed with a spray coating. The operating
pressure and spray rate can be steplessly adjusted by turning the handle.
Replacements, repairs, new adjustments and sealing
should only be performed by qualified persons.
