Water and Cleaning / Pegemittel 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 pressu
-
re by the high pressure pump to the lance. The high pressure jet is formed by
the nozzle at the end of the lance.
Detergent and caring agents can be added through a high pressure injector
(special accessory). Up to max 20m HP hose length.
The rules concerning the environment, refuse and ground water
protection must be complied with!
(Information to be obtained from environmental dept, town
works, etc.)
Lance with trigger gun
The machine can only be operated when the safety trigger is squeezed. 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 increase in pressure when the trigger gun is closed causes the unloader
valve-safety valve to open. The pump remains switched on and continues to
pump liquid through the pump at reduced pressure. When the trigger gun is
opened, the unloader valve - safety valve closes and the pump ressumes pres

The trigger gun is a safety device. Repairs should only be performed by qua
-
lied 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 p 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 qualied persons.
