Safety precautions
When using high pressure water for
cleaning, make sure that there is a clearly
noticeable recoil effect on the lance.
Therefore ensure a firm footing
(see chapter „Technical data“)
Apply the safety catch on the spray gun
after each use in order to prevent
unintentional spraying!
Persons operating the machine should wear the necessary protective clothing,
i.e. waterproof clothing, rubber boots, safety goggles, headwear etc. It is prohibited
to use the machine in close vicinity to people lacking suitable protective clothing !
Do not spray against matter containing asbestos or other hazardous substances !
Never spray liquids containing solvents like varnish solvents, petrol, oil or
similar liquid!
Due to the high pressure jet, damage may occur on the objects to be cleaned,
e.g. car tires; therefore, a minimum distance of 30 cm is to be kept.
Prior to putting the high pressure cleaners into operation, check its components
(HP hose, power supply cables, safety trigger gun) for any damage. Replace defect
or damaged components!
The high pressure cleaner is to be properly used. The user is required to adhere
to local requirements and to watch out for any persons in the danger zone!

9
Safety notes - This is prohibited!
Never allow children or untrained persons
to use the high pressure cleaner!
Never direct the water jet at the machine
itself!
The machine may not be placed within
reach of the water jet spray mist!
Never direct the water jet at power sockets
or any other electrical installations!

Functional details
Please note - important: Lack of water
Lack of water occurs more often than you
probably believe. The more powerful a
high-cleaner is the greater is the danger
that a lack of water occurs. If there is only
an insucient amount of water available,
cavitation (water-gas mixture) arises inside
the pump, which is normally noticed too
late or even not at all. The pump will be
destroyed. Please check the available
quantity of water by filling a bucket with
liter scale for one minute .
A minimum water quantity of 7.5 l/min is needed for the high pressure cleaner
to operate.
I f the metered quantity of water is too small, you have to use a dierent
water connection, guaranteeing the necessary output.
Lack of water leads to an accelerated wear of the joints (guarantee void).
Never let the pump run dry for more than 20 seconds.
Water supply
Please pay attention to the regulations of your waterworks company!
In accordance with DIN EN 61770, the machine may not be directly
connected to the public drinking water supply lines. A brief connection
however is permissible according to DVGW (German Association
for Gas and Water Aairs) if a non-return valve with tube ventilator
(Kränzle order no. 41.016 4) is built into the water supply. Once the
water has passed through the non-return valve it is no longer
considered as drinking water. Also indirect connection to the
public drinking water supply lines is permissible by way of free
emission in accordance with EN 61 770; e.g. by using a reservoir
with a float valve. Direct connection to a non-drinking water
supply line is permissible.

12
Functional details
Insucient quantity of electricity
If there are too many collectors in your
proximity connected to the network at the
same time, the available voltage and the
current intensity may decline. Consequently
the motor of the high pressure cleaner does
not start or even blows. The power supply
may also be insucient if the power cable is
too long or too thin.
If extension cables are too long, this may
lead to a voltage drop causing malfunctions
or start-up diculties.
Kränzle 1050 P: 230 Volt / 50 Hz
Check the line fusing and have the voltage and the available current
intensity checked by an expert in case of uncertainty.
Electrical connection
The machine is supplied with a 5 meter electrical power cable with plug. The mains
plug must be fitted to a standard grounded socket with a 30 mA residual current
operated device. The socket must be protected with a 16 A fuse on the mains side.
When using an extension cable, this must have an earthed lead which is properly
connected to the socket. The conductors in the extension cable must have a
minimum cross section of 1.5 mm². Plug connections must be of a spray-proof design,
and may not be located on a wet floor. When using a cable drum, always keep the
cable wound as far as possible.

13
Functional details
Water and cleaning / care products 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!
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 pressure. When the trigger is released, the trigger gun closes and any
further spraying of liquid from the lance is stopped. The pressure thrust serves to close
the start/stop system, thus causing interruption of the energy supply to the motor.
Owing to this innovative system the high pressure hose is relieved and enables higher
durability of the hose. Opening the gun causes the start/stop system to open, the
electric motor is automatically restarted and the pump starts to transfer the water
on to the high pressure jet where the cleaning jet is generated .
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 components authorized by the manufacturer.
Replacements, repairs, new adjustments and sealing should only be
performed by qualified persons.
Prior to putting the machine into operation make sure that all safety
instructions be observed.

14
Functional details
Motor overload protection
The motor is protected against overloading by means of an overload protection de-
vice included in the motor coil. In the event of overloading or jamming, the excess
temperature cut-out serves to switch othe motor. In case of repeated switching
o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 qualified
persons when the machine 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 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.

15
Putting into operation
Do not place high pressure cleaner on rough surface because unit tends to
vibrate during operation.
When carrying the high pressure cleaner, make sure to bear in mind the
weight of the machine, see technical data.
Neither set up or operate the K 1050 P in rooms where there is a risk of fire
or explosion nor put it into puddles. Do not use the machine under water.
If, none the less, the machine is operated in a hazardous area,
the applicable safety regulations are to be observed.
