Water and cleaning system
Water can be connected at mains pressure (1-8 bar pre-pressure) to the high-pressure
pump. 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 with safety catch
The machine can only be operated when the trigger of the trigger gun with safety catch is
pulled. When the trigger is pulled, the trigger gun opens.
The liquid is then pumped to the
nozzle. The spray pressure increases and quickly reaches the selected operating pressu-
re. When the trigger is released, the trigger gun closes and any further spraying of liquid
from the lance is stopped. The pressure gauge must show 0 bar. When the trigger gun
with safety catch is closed the increase in pressure causes the pressure control valve/
safety valve to open. The motor is switched off by the pressure switch. When the trigger
gun is opened, the pressure control valve/safety valve closes, the motor is started and
the pump resumes pressure spraying from the lance with the selected operating pressu-
re.
The trigger gun with safety catch is a safety device.
Repairs should only be performed by qualified persons.
Should replacement parts be required, use only compon-
ents authorized by the manufacturer.
Pressure control valve - safety valve
The pressure control 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 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.
Total stop system
Kränzle 1122 TS T high-pressure cleaners are equipped with a total stop system. If the
main switch is switched on the motor is started by a pressure switch, as soon as the trig-
ger gun with safety catch is operated. If the trigger gun is released the motor is switched
off at once.
