Functional details
Water and cleaning system
Water must be supplied to the high pressure pump under pressure or (only for high-
pressure cleaner X 8/150 TST) directly sucked in out of a pressureless container.
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!
Safety jet pipe with safety trigger gun
The high-pressure cleaner can only be operated when the trigger of the safety
deactivation trigger gun's trigger is actuated. When the trigger is pulled, the
safety trigger gun opens. The liquid is then transported to the nozzle. The spray
pressure increases and quickly reaches the operating pressure. When the trigger is
released, the safety trigger gun closes and any further spraying of liquid from the
safety jet pipe is prevented. The stainless steel pressure gauge must show 0 bar.
The increase in pressure when the safety trigger gun is closed causes the pressure
control valve/safety valve to open. The motor is switched off by the pressure
switch. When thesafety trigger gun is opened, the pressure control valve/safety
valve closes, the motor is started and the high-pressure pump resumes pressure
spraying from the safety jet pipe with the selected operating pressure.
The safety 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.
Pressure control valve/safety valve
The pressure control valve/safety valve protects the high pressure cleaner 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.

Functional details
Motor protection switch
Motor is protected against overload by means of a motor protection switch.
In case of motor overload or blocking, the motor of the high pressure cleaner
switches off automatically. If motor tends to switch off repeatedly, make sure
to detect appears. Make sure to detect and remedy the cause of the failure.
Replacements and inspection work should only be performed by
qualified persons when the high pressure cleaner is disconnected from
the power supply, i.e. with plug pulled out from the electrical socket.
Totalstop system
The X-series features a totalstop system. If the main switch is switched on, the
motor is started via a pressure switch when opening the safety trigger gun. When
closing the safety trigger gun the motor is switched off immediately.
High pressure hose and spray device
The high pressure hose and spray device which are part of the X-series
equipment, are made of high quality material and engineered to conform with
the operating conditions of the high pressure cleaner and are duly labeled.
If replacement parts are required, only such parts that are authorized
by the manufacturer may be used. The warranty is automatically void if
spare parts of third-party providers are used! The high pressure hose and
spray device must be connected in a pressure-tight manner
(without leakage).
The high pressure hose may not be driven over, pulled excessively, or
twisted. The high pressure hose may under no circumstances be pulled
over sharp edges. Defective high pressure hoses must not be repaired
(acc. to DIN 20022) but have to be replaced by new hoses approved by
the manufacturer.
Prior to putting the high pressure cleaner into operation make sure
that all safety instructions be observed.
