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 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.
Lance with trigger gun
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 per-
formed by qualified persons.
Unloader valve - safety valve
Environmental, refuse disposal and water
protection regulations must be observed !
Water and Cleaning 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 high
pressure injector.
