Water And Cleaning System; Lance With Trigger Gun; Unloader Valve - Safety Valve - Kranzle 1120 Operating Manual

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.
Detergent and caring agents can be added through a high
pressure injector.Up to max 20m HD 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
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 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.
*(see page 22:"Stopping leaks from the hose or gun".)
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.
