Range of application
Use machines for cleaning tasks with high-pressure water jet and detergents or with
high-pressure water jet without detergents only.
Inspections
The machine must be inspected according to the “Guidelines for Liquid Spray Devices”
at least once every 12 months by a qualified person, to ensure that continued safe
operation is guaranteed. The results of the inspection are to be recorded in writing. This
may be done in any form. For inspection reports see pages 58-59.
High-pressure cleaners used for commercial purposes
have to be checked by a qualified person at least every 12
months!
Accident prevention
The machine is designed for accidents to be impossible if used correctly. The operator is
to be notified of the risk of injury from hot machine parts and the high pressure water jet.
The “Guidelines for Liquid Spray Devices” must be complied with (see pages 36-38).
Oil change:
The first oil change should be carried out after approximately 50 operating hours. After
that no further oil change will be necessary to perform an oil change for the life cycle of
the high-pressure cleaner. If it becomes necessary during repairs, or because the oil has
a greyish colour then the oil draining screw should be opened and the oil emptied into a
container. The oil is to be caught in the reservoir and disposed of in an approved man-
ner. New oil: 0.25 l - Motor oil: W 15/40.
Oil leakage: If oil leaks contact your nearest after-sales
service (dealer) at once. (Enviroumental damage, damage
to the transmission)
In case of increased humidity or fluctuations in
temperature development of condensed water is possible;
if the oil turns grey, it must bee changed.
General rules

Safety precautions
Bear in mind that during cleaning tasks
with a high-pressure water jet a significant
recoil at the lance arises. Please stand
firmly.
Apply safety catch on the trigger gun after
each use, in order to prevent
unintentional spraying!
Always aim the underbody lance! Bear
in mind when using a curved or angled
spraying lance that there is a significant
amount of torque in the recoil (the under-
body lance is available as optional acces-
sory)

8
Never direct the water jet at
people or animals!
Never direct the high-pressure jet at
yourself or other persons, not even to
clean clothing or shoes.
Safety precautions – This is prohibited!
Only use power cables which are in
perfect working order!
Do not damage the power cable or
repair it incorrectly!
Never pull the high pressure hose if
it has formed kinks or “nooses”!
Never pull the hose over sharp
edges!

9
Never allow children or untrained per-
sons to use the high pressure cleaner!
Never direct the water jet at the
machine itself!
The machine may not be placed within
reach of the water jet spray mist!
Never direct the water jet at power
sockets or any other electrical installa-
tions!

Please note - important:
Lack of water
Lack of water occurs more often than you
probably believe. The more powerful a
high-cleaner is the greater is the danger
that a lack of water occurs. If there is only
an insufficient amount of water available,
cavitation (water-gas mixture) arises inside
the pump, which is normally noticed too
late or even not at all. The pump will be
destroyed!
Please check the available quantity of water
by filling a bucket with litre scale for one
minute .
If the metered quantity of water is too small, you have to use a
different water connection, guaranteeing the necessary output.
Lack of water leads to an accelerated wear of the joints
(guarantee void).
A minimum water quantity of 10 litres per minute must be available to
guarantee a trouble-free operation of the Kränzle 1152 TS T.
Water supply
Please pay attention to the regulations of your waterworks company!
In accordance with DIN EN 61770, 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 non-return valve with tube ventilator
(Kränzle order no. 41.016 4) is built into the water supply
. Once the
water has passed through the non-return valve it is no longer con-
sidered as drinking water.
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.

11
Insufficient quantity of electricity
If there are too many collectors in your
proximity connected to the network at the
same time, the available voltage and the
current intensity may decline.
Consequently the motor of the high-pres-
sure cleaner does not start or even blows.
The power supply may also be insufficient
if the power cable is too long or too thin.
If extension cables are too long, this may lead to a voltage drop causing malfunctions or
start-up difficulties.
Check the line fusing and have the voltage and the available current
intensity checked by an expert in case of uncertainty.
Kränzle 1152 TST:
230 V ~, 12,0 A, 50 Hz
Electrical connection
The machine is supplied with a 5 meter electrical power cable 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.
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 the minimum cross section must be
2.5 mm! When using a cable drum, always keep the cable wound as far as possible.

12
Water and cleaning system
Water can be connected at mains pressure (1-8 bar pre-pressure) to the high-pressure
pump. 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!
Lance with trigger gun with safety catch
The machine can only be operated when the trigger of the trigger gun with safety catch is
pulled. When the trigger is pulled, the trigger gun opens.
The liquid is then pumped to the
nozzle. The spray pressure increases and quickly reaches the selected operating pressu-
re. When the trigger is released, the trigger gun closes and any further spraying of liquid
from the lance is stopped. The pressure gauge must show 0 bar. When the trigger gun
with safety catch is closed the increase in pressure causes the pressure control valve/
safety valve to open. The motor is switched off by the pressure switch. When the trigger
gun is opened, the pressure control valve/safety valve closes, the motor is started and
the pump resumes pressure spraying from the lance with the selected operating pressu-
re.
The trigger gun with safety catch is a safety device.
Repairs should only be performed by qualified persons.
Should replacement parts be required, use only compon-
ents authorized by the manufacturer.
Pressure control valve - safety valve
The pressure control 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 qualified persons.
Total stop system
Kränzle 1152 TS T high-pressure cleaners are equipped with a total stop system. If the
main switch is switched on the motor is started by a pressure switch, as soon as the trig-
ger gun with safety catch is operated. If the trigger gun is released the motor is switched
off at once.
Kränzle technology

13
Motor protection switch
The motor is protected from overload by a motor protection switch, which 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 40).
Replacements and inspection work should only be
performed by qualified persons when the machine is
disconnected from the power supply, i.e. with plug pulled
out from the electrical socket.
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. (max. hose length 20 m)
If replacement parts are required, only such parts that are
authorized by the manufacturer may be used. The warran-
ty is automatically void if spare parts of third-party provi-
ders are used! The high pressure hose and spray device
must be connected in a pressure-tight manner (without
leakage).
The high pressure hose may not be driven over, pulled
excessively, or twisted. The hose may under no circum-
stances be pulled over sharp edges. Defective high-pres-
sure hoses must not be repaired (acc. to DIN 20022) but
have to be replaced by new hoses appoved by the
manufacturer.
Operate high-pressure cleaner in horizontal position only.
Never direct the high-pressure jet at people or animals.
Never direct the water jet at power sockets or any other electri-
cal installations!
Explanatory symbols afxed to the high-pressure cleaner
The high-pressure cleaner may only be operated in horizon-
tal position!

When using cleansing agents
Suction of cleansing agents by means of the detergent injector is only possible if the
Vario Jet lance is fitted. The lance mus be set to low pressure.
Observe specifications of detergent manufacturer!
e.g. protective equipment, rules for waste water treatment etc.
Caution: Solvents!
Never suck in liquids containing solvents like varnish sol-
vents, petrol, oil or similar liquid! Observe specifications
of detergent manufacturers! Seals inside the appliance
are not resistant against solvents! The spray mist of
solvents is highly inflammable, explosive and poisonous .
Suction of detergents
1. Please chemicals filter into container
with cleansing agent.
2. To reach the low pressure push Vario
nozzle to the front so that the injector can
suck in the cleansing agent.
3. The chemicals supply is automatically
stopped when closing the Vario nozzle by
pushing it backwards.
Let cleansing agent take effect and then
spray off with a high-pressure jet.

design the Kränzle 1152 TS T cleaners can
be stored practically anywhere.
Store in a place-saving manner

20
The pressure gauge shows full pressure,
but emerges from the nozzle only little
water or no water at all.
(Inside the pressure gauge there is no
water but a filling with glycol to damp the
vibration of the pointer.)
Proceeding:
Switch off the cleaner. Pull plug from the
socket. Operate trigger gun with safety
catch seveal times to decrease the
pressure.
Unscrew trigger gun and lance first,
then rinse high-pressure gun to remove
possible soiling.
Check water inlet filter for soiling.
If the problem still exists, take wire (paper
clip) and push through nozzle opening.
If this procedure is not successful, the
nozzle has to be dismantled and cleaned
or even replaced, if necessary.
Small repairs - do it yourself!
No water from the nozzle but the gauge shows full pressure:
Most likely the nozzle is blocked.
CAUTION! Pull plug from socket prior to starting
any repair work!
