Water supply system
The water must be lead to the high pressure cleaner under pressure (2 – 8 bar
ad-mission pressure). A oat valve regulates the water inlet. Then, the water is
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.
Detergent and caring system
The high pressure pump can also suck a detergent/caring
agent and mix it with the high pressure jet. The additive
is sucked through the pump and brought in with the set
pressure.
Insert the detergent hose into the detergent container and
open the detergent valve (6). The detergent must have
the ph-value 7-9 neutral.
The detergent discharges with the water at the high pres-
sure nozzle.
Only open the dosing valve, if the chemistry sieve is placed in
a liquid. Sucked air leads to destruction of the pump seals !!!
The rules concerning the environment, refuse and
ground water protection must be complied with!
Description

Lance with spray gun
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. For the deairing of the system open and close the gun quickly
a few times. 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-safety valve to open. The pump remains switched on and continues to pump
liquid through the pump at reduced pressure. When the spray gun is opened, the
unloader valve - safety 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 qualied persons. Should replacement
parts be required, use only components authorized by
the manufacturer.

High pressure hose and spraying 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
spraying device must be connected in a pressure-tight manner.
The high pressure hose may not be driven over, pulled excessively or
twisted. Hose lines are wear parts. Guarantee is accepted only for ma-
nufacturing errors, not for external damages.
High pressure hose lines and spraying equipment must not be repai-
red, but replaced by a new hose or spraying equipment.
Unloader valve - safety valve
The unloader 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 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 qualied persons.
Take care that all screw connections are pressure-tight.
A leakage of gun, high-pressure hose or hose drum has to
be repaired at once. Leakages lead to an increased wear
and to a possible malfunction of the delayed motor cut-out.
Operator’s task:
Prior to each usage of this liquid spraying device, the ope-
rator is obliged to check if all safety relevant parts are in
perfect working condition. (e.g. safty valves, high-pressure
hose, cables and connections, spraying devices, etc. )

With Total-Stop-System
The Kränzle quadro 9/170 TS, 11/140 TS und 12/150 TS - high
pressure cleaners are equipped with a Total-Stop-System.
If the main switch is switched on, the motor is started by means
of a pressure switch as soon as the gun is operated. The pump quickly reaches
the set operating pressure. When the gun is closed the motor is cut off immediate-
ly.
Replacements and inspection work should only be performed by qua-
lied 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 re or explosion nor put it into puddles. Do not use the machine under
water. The device must not stand in the spray area of the high pressure 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
machine are not resistant to solvents! The spray of solvents is inam-
mable, 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 supplied with an electrical power cord with plug.
The mains plug must be tted to a standard grounded socket with a 30mA re-
sidual current operated device. The socket must be protected with a 16A delay
action fuse on the mains side.
KRÄNZLE quadro 9/170 TST, 11/140 TST = 230 Volt / 50 Hz
KRÄNZLE quadro 12/150 TST = 400 Volt / 50 Hz
(phase-sequence not signicant)
When using an extension cable, this must have a grounded lead which is properly
connected to the socket. The conductors in the extension cable must have a mini-
mum cross section of 1.5 mm². Plug connections must be of a spray-proof design
and may not be located on a wet oor.
CAUTION !
The use of extension cables which are too long may lead to malfunctions and start
up difculty. If the extension cable is longer than 10 m it must have a minimum cross
section of 2.5mm².
When using a cable drum, always keep the cable unwound as far as possible.

External suction
If water is to be sucked
from an external contai-
ner for the high pressure
cleaner, the connection
hose between the high
pressure pump and the
water tank must be scre-
wed off and the suction
hose must be connected
via a double nipple 3/4“ (Order no.: 46.004) to the con-
nection hose.
Make sure that the water is clean. Use the Kränzle suction hose with suction lter.
(Order no. 15.038 3)
Maximum suction height 2.5 m, maximum water temperature for direct suc-
tion: 60°C
(see technical data on page 2)

To shut down the pump
1. Switch off the machine. Switch to „0“ position.
2. Cut off the water supply.
3. Open the spray gun briey 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 lter.
To shut down the pump:
Frost protection
Normally after operation, there is still some water in the device. Thus, you must take
special measures to protect the device from frost.
- Completely drain the device
For this purpose, separate the device from the water supply. Then, turn on the
main switch and open the gun. Now, the pump presses the remaining water out of
the water tank and the pump. However, do not allow the device to operate without
water for longer than one minute.
- Fill the device with antifreeze agent
If the device is not operated for longer periods, especially over the winter, you
should pump an antifreeze agent through the device. For this purpose, ll the anti-
freeze agent into the water box and turn on the device. Wait with opened gun,
until the agent spurts out of the nozzle.
However, the best way to protect the device from frost is
to store it at a frost-free location.
Suction of detergents
Put chemistry sieve number 5 into the deter-
gent container. Open the detergent valve (6),
then the detergent is sucked in. When closing
the detergent valve, the chemistry supply is
automatically closed. Allow detergent to act and
then wash off. (see page 5).
Note that you must always comply with the
instructions provided by the manuf-
acturer of the detergent (e.g. safety
clothing) and the water protection regu-
lations!
Only open the valve, if the chemistry sieve
is in a liquid. Sucked in air leads to the
destruction of the pump seals !!!
Damages to the pump caused by sucked in air
are not covered by the guarantee.
