Water - and Cleang - Care System
Water can be connected at mains 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.
Cleaning and caring agents can be mixed with the water by a low pressure injector.
Environmental, refuse disposal and water protection
regulations must be observed !
Lance with trigger gun
The machine can only be operated when the safety trigger is squeezed.
When the lever ist 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 ist released, the trigger gun closes and any further spraying of
liquid from the lance ist stopped.
The increase in pressure when the trigger gun is closed causes the unloader valve-
safety valve to open. The pump remaines switched on and continues to pump liquid
through the pump at reducated pressure.
When the trigger gun ist opened, the unloader valve - safety valve closes and the
pump ressumes pressure spraying from the lance.
The trigger 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.
Unloader valve - safety valve
The unloader 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
operating. The limit nut on the handle is sealed with a spray coating.
The operating pressure and spray rate can be steplessly adjusted by tuning the
handle.
Replacements, repairs, new adjustments and sealing should only be
performed by qualified persons.
