General rules
Intended use
This high pressure cleaner is to be used solely for high pressure water jet cleaning
applications without detergents or low-pressure cleaning work with detergents
(e.g. with a foam injector or washing brush).
Environmental, refuse disposal and water protection regulations
must be observed!
Inspections
The high pressure cleaner must be inspected according to the “Guidelines for
Liquid Spray Devices” at least once every 12 months by a qualified person, to
ensure that continued safe operation is guaranteed. The results of the inspection
are to be recorded in writing (see Inspection reports).
High pressure cleaners used for commercial purposes have to be
checked by a qualified person at least every 12 months!
Accident prevention
The high pressure cleaner is designed for accidents to be impossible if used
correctly. The user is to be notified of the risk of injury from hot machine parts
and the high pressure jet. The “Guidelines for Liquid Spray Devices” must be
complied with.

13
General rules
Oil change
The first oil change should be carried out
after approximately 50 operating hours,
then every year or after 250 operating
hours. If the oil turns grey or white,
you must change the oil. In case of
exchanging oil being required, the oil
drain screw must be opened above a
container and the high pressure cleaner
be emptied. The oil is to be caught in the
reservoir and disposed of in an approved
manner.
New oil: 1.l
Kränzle Gear Oil (Item no.: 400932)
or 10/W60 SAE Semisynthetic oil.

Oil leakage
If oil leaks contact your nearest after-sales service (dealer) at once.
(environmental damage, damage to the transmission).
In case of increased humidity or fluctuations in temperature
development of condensed water is possible. If the oil turns grey
or white, you must change it.

Functional details
Please note: Lack of water
Lack of water occurs more often than you
probably believe. The more powerful a high
pressure cleaner is the greater is the danger
that a lack of water occurs. If there is only
an insufficient amount of water available,
cavitation (water-gas mixture) arises inside
the high pressure pump, which is normally
noticed too late or even not at all. The high
pressure pump will be destroyed. Please
check the available quantity of water by fil-
ling a bucket with liter scale for one minute.
Required minimum quantity of water (see technical data).
If the metered quantity of water is too small, you have to use a
different water connection, guaranteeing the necessary output.
Lack of water leads to an accelerated wear of the joints (no warranty).
Never let the high pressure pump run dry for more than 60 seconds.
Water supply
Please pay attention to the regulations of your waterworks company!
In accordance with DIN EN 61770, the high pressure cleaner 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 Affairs) if a non-return
valve with tube ventilator (Kränzle item no.: 410164) 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.

15
Functional details
Insufficient 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 insufficient if the power supply
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 difficulties.
Check the line fusing and have the voltage and the available current
intensity checked by an expert in case of uncertainty (see technical data).
Electrical connection
The high pressure cleaner is supplied with a 5 meters long power supply cable.
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. For extension
cables of more than 10 m in length, the minimum cross-section must be 2.5 mm²!
When using a cable drum, the power supply cable always must be unwound all
the way.

16
Water and cleaning system
Water must be supplied to the high pressure pump under pressure or 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 perfor-
med by qualified persons. Should replacement parts be required, use
only components authorized by the manufacturer.
Functional details

17
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.
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.
Total stop system with delayed motor cut-off
After startup and switching on the high pressure cleaner a green light is displayed.
When opening the safety trigger gun the motor is started via a total-stop system.
When closing the safety trigger gun the motor is switched off only after 30 seconds.
The delayed switch-off is necessary because switching on and off motors frequently
on high pressure cleaners of this size may involve heavy load on the power network
and cause increased wear of internal electrical parts.
Functional details

18
Safety shutdown
If the high-pressure cleaner is accidentally not turned o after use or the safety
trigger gun is not used for 20 minutes, the high-pressure cleaner automatically
changes into safety state by deactivation. By operating the main switch once
more, the high-pressure cleaner is activated again.
High pressure hose and spray device
The high-pressure hose and spray device which are part of the WS series
equipment, are made of high-quality material and engineered to conform
with the operating conditions of the high-pressure cleaner and are duly labelled.
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.
