Description
Water and Cleaning System
Water can be connected at mains pressure to the high pressure pump or it can
be sucked dirctly from a storage tank. 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 !
Unloader valve - safety valve
The unloder 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 of the unloader valve is sealed with a spray
coating.
Replacements, repairs, new adjustments and sealing
should only be performed by qualified persons !
Lance with trigger gun
The machine can be operated when the safety trigger is squeezed.
When the lever is squeezed, the spry 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 increase in pressure when the trigger gun is closed causes the unloader
valve - safety valve closes and the pump ressumes pressure spraying from the
lance.
The 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.

Description
Motor protection switch
The motor is protected from overload by a motor protection switch, which
automatically cuts out the motor in the event of overload.
However, should the switch trip frequently, the cause of the malfunction should
be located and rectified (see page 6).
Replacements and inspection work should only be performed ba
qualified persons when the machine is disconnected from the
power supply, i.e. pull the plug from the electrical socket before
such work is carried out.
Setting up
Location
Neither set up and operate the machine in rooms where there is a risk
of fire or explosion nor put it into puddles.
Do not use the machine under water.
CAUTION !
Never use liquid containing solvents such as paint thinners, patrol, oil
or similar liquid matter.
Pay attention to the instructions of the manufacturer of the
cleaning agents. The seals in the machine are not resistant to
solvents. The spray of solvents is inflammable, explosive and
poisonous.
CAUTION !
When running your high pressure cleaner with hot water of 60 °C raised

pressure hoses).
- Only use clean water ! Protect from frost !
CAUTION !
Please pay attention to the regulations of your waterworks company.
In accordance with DIN 1988, the machine may not be directly connected to
the public drinking water supply lines.
A brief connection however is permissible according to DVGW (German
Associatin for Gas and Water Affairs) if a tube ventilator with reflux valve
(Kränzle Order-No. 41.016 4) is built into the water supply.
Also indirect connection to the public drinking water supply lines is
permissible by way of free emission in accordance with DIN 1988, part 4;
e.g. by using a reservoir with a float valve.
Direct connection to a non-drinking water supply line is permissible.
High pressure hose and spray device
The high pressure hose and spraying device suplied with the machine are
made of high grade material, they are also optimized for the machine and
marked as required by appropriate regulations.
If replacement parts are required, only such parts that are
authorized by the manufacturer and which bear the markings
required by appropriate regulations may be used. The high
pressure hose and spray device must be connected in a pressure-
tight manner. The high pressure hose may not be driven over,
pulled excessively, or twisted. The hose may under no
cicumstances be pulled over sharp edges, since otherwise the
guarantee is automatically void.

The recoil is less
than 20 Nm.
Always aim the
underbody lance.
Note, when using an
angled underbody lance,
like for example lance
No. 41.075, that there is a
certain amount of torque
(twisting motion) in the
recoil. (See also notice
on page 2).
