Water system
The water must be lead to the high pressure cleaner under pressure (2 – 8 bar ad-
mission pressure).Two floatvalvesregulate the water inlet.Then, the wateris
sucked by the high pressure pump from the water tank and supplied to the lance
under the set pressure. The high pressure jet is formed by the nozzle at the end of
the lance.
Lance with spray gun
Themachine can only be operated whenthe safety trigger is squeezed.
When the lever is squeezed, the spray gun opens. The liquid is then pumped to the
nozzle.Thespraypressureincreasesand 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 and the pressure gauge must show 0
bar.
The increase in pressure when the trigger gun is closed causes the unloader valve
to open. The pumps remain switched on and continue to pump liquid through the
depressurized circuit. When the spray gun is opened, the unloader valve closes
and the pump ressumes spraying from the lance with the selected operating
pressure.
The spray 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.
High pressure hose and spraying device
Thehigh pressure hoseandspraying device suppliedwiththe machine aremadeof
highgrade material. They are alsooptimizedfor the machine and markedasre-
quiredby theappropriateregulations.
If replacement parts are required, only such parts that are authorized
by the manufacturer and which bear the markings required by the ap-
propriate regulations may be used. The high pressure hose and
spraying device must be connected in a pressure-tight manner.
Thehigh pressure hose maynotbe driven over,pulled excessively or
twisted.Hose lines are wear parts.Guaranteeis accepted only for
manufacturingerrors, not forexternal damages.
High pressure hose lines and spraying equipment must not
be repaired, but replaced by a new hose or spraying
equipment.

Unloader valve
The unloader valve protects the machine from a build up of excess pressure and is
set to the maximum operating pressure. The limit nut on the handle is sealed with a
spray coating.
Replacements, repairs, new adjustments and sealing
should only be performed by qualified persons.
Safety valve
In addition to the unloader valve the machine is equipped with a safety valve. This
valve is set to a value approx. 15% higher than that of the unloader valve and it
switches in case of unacceptable excess pressure, thus allowing the water to be
pumped back into the float box .
Replacements, repairs, new adjustments and sealing
should only be performed by qualified persons.
Automatic starter
Thehigh-pressure cleaner is equipped withan automatic starter controlling thestart-
upof both motors.Having switched onthe machine thefirst motor startsand after two
seconds the second motor. Thus current peaks in the electric circuit are avoided.
When working with the high-pressure gun be sure to stand
firmly because there is an additional recoil at the lance as
soon as the second pump is switched on.

Description
Delayed motor cut-out
Frequent, work-necessitated switching on and off of motors on
machines of this size puts a heavy load on the electric circuit and
causes increased wear on internal electrical parts. Therefore the
motor of the new KRANZLE devices only switches off 30 seconds after closing the
gun and then goes to stand still. By opening the gun, the device is started again.
Safety cut-out
If the device is accidentally not turned off after use or the pistol is not used for 20
minutes, the device automatically goes into the safety mode. By operating the main
switch, the device is activated again.
Replacementsandinspection workshouldonly beperformedbyqualified
persons when the machine is disconnected from the power
supply, i.e. the plug pulled out from the electrical socket.
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.Thedevice mustnot standin thespray areaof thehighpressure jet.
CAUTION !
Never suck in 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
machineare not resistant to solvents! The sprayofsolvents is inflamma-
ble,explosive andpoisonous.
CAUTION !
Whenrunning your high pressurecleanerwith hot water of60°C raised
temperatures occur. Do not touch the machine without safety
gloves!

400 V / 50 Hz
Electrical connection
The machine is supplied with an electrical power cord with plug.
The mains plug must be fitted to a standard grounded socket with a 30mAresidual
current operated device. The socket must be protected with a 32A delay action
fuse on the mains side.
KRÄNZLE quadro = 400 Volt / 50 Hz (phase-sequence not significant)
When using an extension cable, this must have a grounded lead which is properly

Brief operating instructions:
1. Connect high pressure hose with spray gun.
2. Connect to suitable water supply.
3. Connect current - (400 Volt three-phase current).
4. Switch on machine and start cleaning.
5. After having completed the cleaning process, put main switch in zero
position and by opening the gun, reduce the pressure in the high
pressurehose.
Then, the high pressure hose can be rolled up.
- Only use clean water ! Protect from frost !
CAUTION !
Please pay attention to the regulations of your waterworks company.
In accordance 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.

Preparation for use
To controlthehigh pressure cleaner
put
1. the foot against the tilt bases and
2. then pull the device towards you.
13
When tilting the machine residual water inside the water box might float
out of the water inlet at the back.
6. When operating the machine for the first time
or after an extended stand still it may happen
that an air pocket is formed in the second
pump.
Release screw (a) of the check valve and take
out screw and check valve. Place a container
in front of the opening and briefly switch on the
machine (approx. 5 seconds) thus allowing the
pump to press out the air.
Now you can screw down the check valve again and your high-pressure
cleaner works with the desired quantity of water.

3. Open the spray gun briefly until the pressure is released.
4. Apply the safety catch on the spray gun.
5. Remove the water hose and spray gun.
6. Pull the plug from the socket.
7. Winter: store the pump in rooms above 0°C.
8. Clean the water filter.
To shut down the pump:
Frost protection
Normallyafter operation, there is stillsome waterin the machine.Therefore youmust
take special measures to protect the HP cleaner from frost.
-Completely drain the appliance
Forthis purpose, separatetheappliance from the water supply.Then, turnon the
mainswitch andopen thegun. Now, thepump pressesthe remainingwater from
thewater tank and the pump. However, do not allow the deviceto operatewithout
waterfor longer thanoneminute.
- Fill the appliance with antifreeze agent
Ifthe applianceis notoperated forlonger periods,especially overthe winter,you
shouldpump an antifreeze agent throughthe device.For this purpose,fill theanti-
freezeagent intothe water box and turn on thedevice. Wait withopened gun,
untiltheagent comes fromthe nozzle.
However, the best way to protect the device from frost is
to store it at a frost-free location.
