The machine can only be operated when the safety trigger is squeezed.
The machine can only be operated when the safety trigger is squeezed. When the
lever is squeezed, the spray 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 to open. The pump remains switched on and continues to pump liquid
through the pump at reduced pressure. When the trigger gun is opened, 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.
Lance with trigger gun
The unloader valve - safety valve protects the machine from a build p 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 per-
formed by qualified persons.
Unloader valve - safety valve
Environmental, refuse disposal and water
protection regulations must be observed !
Water and Cleaning System
Water can be connected at mains pressure to the high pressure pump or it can be
sucked directly 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.
Cleaning and caring agents can be mixed with the water by a high
pressure injector.

The motor is protected from overload by a motor protection switch, which automati-
cally 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 by qualified
persons when the machine is disconnected from the power
supply, i.e. pull out the plug from the electrical socket.
Motor protection switch
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.
Never use liquid containing solvents such as paint thinners, petrol, oil or
similar liquid matter. Pay attention to the instructions of the
manufacturers of the cleaning agents. The seals in the ma-
chine are not resistant to solvents. The spray of solvents is inflammable,
explosive and poisonous.
CAUTION !
CAUTION !
When running your high pressure cleaner with hot water of 60 °C raised
temperatures occur. Do not touch the machine without safety
gloves!

The machine is supplied with an electrical power cord with plug.
The mains plug must be fitted to a standard grounded socket with a
30mA residual current operated device. The socket must be protected
with a 16A delay action fuse on the mains side.
KRÄNZLE 145 T - 230 Volt 50 Hz
KRÄNZLE 175 T - 400 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 mm². Plug connections must
be of a spray-proof design, and may not be located on a wet floor.
(with extension cables of more than 10 m - 2.5 mm2)
Electrical connection
The use of extension 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.
CAUTION !

Brief operating instructions
are fitted to the machine. Numbers 1-6.
When operating your high pressure cleaner pay attention
that it is in a horizontal position.
1. Connect the high pressure hose with spray gun and machine.
2. Connect to suitable water supply.
3. Flush the air from the pump (open and close the spray gun several times)
4. Make the electrical connection - (KRÄNZLE 145 T 230 Volt A.C.,
KRÄNZLE 175 T 400 Volt three-phase current).
5. Switch on the machine with opened spray gun and commence cleaning.
6. After completing the work, completely empty the pump (switch the motor on for
approximately 20 seconds without the suction and pressure hoses).
Only use clean water ! Protect from frost !
Please pay attention to the regulations of your waterworks company. In accord-
ance with EN 61 770, 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 Affairs) if a tube ventilator with check 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 EN 61 770; e.g. by using a reservoir with a
float valve.
Direct connection to a non-drinking water supply line is permissible.
CAUTION !
High pressure hose and spray device
The high pressure hose and spraying device supplied with the machine are made of
high grade material, they are also optimized for the machine and marked as required
by the appropriate regulations.
If replacement parts are required, only such parts that are authorized by
the manufacturer and which bear the markings required by the 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
circumstances be pulled over sharp edges, since otherwise the guarantee
is automatically void.

As to the recoil -
see notice on page 2!
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 in the recoil.
