Functional details
Water and cleaning system
Water can be connected at mains 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!
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 pressure thrust serves to close the start/stop
system, thus interrupting the energy supply to the motor. Owing to this innova-
tive system, the high pressure hose is relieved, which ensures higher durability.
Operating the safety trigger gun causes the start/stop system to open, the motor
is automatically activated and the high pressure pump starts to transport the
water to the nozzle, where the high pressure jet is produced.
The safety trigger gun is a safety device. Repairs should only be perfor-
med by qualified persons. Should replacement parts be required, use
only components authorized by the manufacturer.
Replacements, repairs, new adjustments and sealing should only be
performed by qualified persons.
Prior to putting the high pressure cleaner into operation make sure
that all safety instructions be observed.

Functional details
Motor overload protection
The motor is protected against overloading by means of an overload protection
device included in the motor coil. In the event of overloading or jamming, the
excess temperature cut-out serves to switch off the motor. In case of repeated
switching off the motor by means of the excess temperature cut-out, make sure
to eliminate the cause of the failure.
Replacements and inspection work should only be performed by quali-
fied persons when the high pressure cleaner is disconnected from the
power supply, i.e. with plug pulled out from the electrical socket.
High pressure hose and spray device
The high pressure hose and spray device which are part of the K 1050 P
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.
