Water And Cleaning System - Kranzle W 11/135 Operating Manual

Water and Cleaning System

The water is fed to the high pressure pump under pressure.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 !
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
leve r 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.(Not with W 11/135).
When the trigger is released, the trigger gun closes and any further spraying of
liquid from the lance is stopped and the manometer must show 0 bar.
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-
sure 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.
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.
