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.
The operating pressure and spray rate can be steplessly adjusted by
adjusting the turn handle.
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 temperatures occur.
Do not touch the machine without safety gloves.

Description
Electrical connection
The machine is suplied with an electrical power cord 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 slow fuse on the mains inside.
KRÄNZLE 105 - 230 Volt 50 Hz
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 mm 2.
Plug connections must be of a spray proof design, and may not
be located an a wet floor.
(With extension cables of more than 10 m the conductor must
have cross section of at least 2,5 mm2.)
CAUTION !
The use of extention cables which are too long may lead to malfunctions and
start-up difficulty.
When using a cable drum, always keep the cable wound as far as possible.

Description
Brief operating instrucions
are fittet to the machine (numbers 1 - 6)
1. Connect the hogh pressure hose with spray gun and machine.
2. Connect the suitable water supply.
3. Flush the air from the pump (open and close the spray gun
several times).
4. Make the electrical connection ( 230 Volt AC).
5. Switch on the machine while the spray gun is open and
commence cleaning.
6. After completing the work, completely empty the pump. (switch
the motor on for approx. 20 sec. without the suction and
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.
Savety notes
Apply the safety catch
on the spray gun
after each use,
in order to prevent
unintentional spraying.
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
