Description
Water and Cleaning System
Water can be connected at mains pressure to the high pressure pump or it
can be sucked dirctly 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 !
Unloader valve - safety valve
The unloder 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 of the unloader valve is sealed with a
spray coating.
The operating pressure and spray rate can be steplessly adjusted by
adjusting the turn handle.
Replacements, repairs, new adjustments and sealing
should only be performed by qualified persons !
Lance with trigger gun
The machine can be operated when the safety trigger is squeezed.
When the lever is squeezed, the spry 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 increase in pressure when the trigger gun is closed causes 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.
