General rules
Range of application
This machine may only be used for cleaning facades, vehicles, containers, pavement
slabs, stables, machines and smilar objects.
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 56 - 57.
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 according to these
instructions). Please read safety notes included in this manual carefully before using the
machine and act correspondingly. Operating staff has to be instructed according to this
manual. The “Guidelines for Liquid Spray Devices” must be complied with.
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.
During the combustion process air is needed and exhaust gas
emerges. If the machine is operated in a confined space, precautions
have to be taken to safely exhaust the fumes. Furthermore a sufficient
ventilation has to be provided for.
Never shut the exhaust gas outlet on top of the machine. Never stoop
over this aperture and never reach into it. Emerging gases are extremely hot!
Do not jam the trigger of the gun during operation!
When carrying through service and maitenance tasks the machine has to
be cut off the power supply system. Put main switch to „0“ and pull plug
out of socket
.
Never operate the machine if cables or other safety-relevant parts (e.g.
excess pressure valve, high-pressure hose, spraying devices, etc.) are
defective.
Safety notes
Page 8
Never operate the machine without supervision. The machine may only
be operated by persons who have been instructed accordingly.
Some parts inside the machine, all water conducting components and all
metal parts of gun and lance are hot during hot water operation. Keep all
hoods and protective covers closed during operation and never touch
any metal parts of gun or lance.
Persons operating the machine should wear the necessary protective
clothing, i.e. waterproof clothing, rubber boots, safety goggles, headwear
etc. It is prohibited to use the machine in close vicinity to people lacking
suitable protective clothing.
The high-pressure jet can generate a high level of noise. If noise exceeds
the maximum allowed levels, users and others in the vicinity must wear
suitable ear protection
.
Do not spray against matter containing asbestos or other hazardous substances.
For safety reasons always switch the main switch to „0“- postion after
having finished the cleaning task (disconnection from power supply).
8
Safety notes
Bear in mind that during cleaning tasks
with a high-pressure water jet a significant
recoil at the lance arises.
Additionally angled lances produce a
clearly perceivable amount of torque.
Apply the safety catch on the spray 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!
Page 9
9
Never allow children or untrained
persons 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 a power
socket!
Never direct the water jet at people or
animals!
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!
Page 10
Lack of water
Lack of water occurs more often than you
probably believe. The more powerful a highpressure cleaner is the greater is the danger
that a lack of water occurs. If there is only
an insufficient amount of water available,
cavitation 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).
Necessary minimum quantity of water: see technical data.
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 considered 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 oat valve. Direct connection to a non-drinking
water supply line is permissible.
10
Please note - important!

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-pressure 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.
Connected load:
Kränzle therm 895 ST: 400 V, 50 Hz (direction of rotation of no importance)
Kränzle therm 1165 ST: 400 V, 50 Hz (direction of rotation of no importance)
Electrical connection
The machine is supplied with an electrical power cable 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 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.
Check the line fusing and have the voltage and the available current
intensity checked by an expert in case of uncertainty.
Page 12

Water and Cleaning System
The water is fed to the high-pressure cleaner under pressure (2-8 bar pre-pressure). A
float valve regulates the water flow in the storage tank. Then the water is sucked directly
from the storage tank by the high-pressure pump and forced with the adusted pressure
through the heat exchanger to the safety spray lance. The high pressure jet is formed by
the nozzle at the end of the safety lance.
Environmental, refuse disposal and water protection regulations
must be observed!
Kränzle technology
Lance with trigger 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. When the trigger is released, the trigger gun closes and any further spraying of liquid from the lance is
stopped. The motor stops.
When actuating the gun once more the pressure control valve - safety valve closes
and the motor is started again. The pump resumes feeding water to the spraying lance
with the selected operating pressure. When the gun is closed, the water hammer opens
the pressure control valve - safety valve and the motor is switched off by the pressure
switch.
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.
Total stop system
The machine is fitted with a Total-Stop-System. If the gun is closed for longer than
approx. 20 seconds, the machine switches off automatically, after 20 minutes the machine moves to safety switch off and you must use the main switch to turn it back on.
The machine restarts automatically when the gun is operated, provided the master
switch is on.
Page 13
13
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. The hose may under no circumstances be pulled over sharp edges,
since otherwise the guarantee is automatically void.
Hoses are wearing parts. The guarantee only covers defects of fabrication no external damages whatsoever.
Defective high-pressure hoses and spraying devices may not be
repaired. They always have to be replaced.
Pressure control valve-safety valve
The pressure control valve allows full adjustment of the quantity and pressure of the
water. The safety valve protects the machine from excessive pressure and cannot be
adjusted beyond the admissible operating pressure. The setting nuts are sealed with
lacquer
.
Replacements, repairs, new adjustments and sealing operations may
only be performed by trained personnel.
Setting for pressure, quantity and temperature
The pressure control valve on the pump
head is used to control the operating
pressure plus the water flow and consequently the water temperature as well.
Turn right to increase the pressure,
turn left to reduce the pressure.

Kränzle technology
The thermostat controls the spray water
temperature.
After you switch on the device, “888” appears in both displays for approx. 1 second
as a test of the functioning of the displays.
The thermostat also monitors the mini-
mum fuel level in the tank with a oating
switch. If the level is below the minimum
amount, the thermostat switches the oil
burner off and the “OIL” sign ashes in
the set temperature display (Pos. 1). If the
unit displays “FLA” in the upper display, a
malfunction in burning exists.
Thermostat
12 3 4 5 6
The thermostat has two operating modes:
1. Temperature mode
This mode is always activated when the unit is switched on or can be selected using the
“°C°” button (Pos. 3). The red LED above the “°C” button and next to the set temperature
display lights up. The desired “Set” temperature is set using the two buttons (+/-, Pos.
5+6) and can be read in the upper display (Pos. 1). If you press the button for a longer
time, the set temperature is quickly adjusted in 5°C increments.
The last set value set is also stored after the unit is switched off and is available again
immediately after switching back on. The current spray temperature can be read from the
bottom display (Pos. 2).
2. Percentage mode
This mode is activated by pressing the “%” button (Pos. 4). The yellow LED above the “%”
button and next to the set temperature display ashes.
In the temperature control system in conventional high-pressure cleaners, and in
temperature mode for this unit, the water temperature is measured at the outlet of the
heater, and the heater is switched On an Off according to the temperature desired by the
user. Due to the large amount of water in the heating coil, it takes a long time until the
temperature sensor registers that the burner has switched on and the desired temperature
has been reached. This means that the temperature increases far above the desired value
or falls far below the desired value
.
Page 15
15
Thermostat - percentage mode
The innovative new percent mode now lets the user specify the switching duration of
the heater in percent using the “+” and “-” buttons (Pos. 5+6) (100% being the max.
temperature) rather than setting the desired temperature. Now the result of the setting
must be checked by using the “Actual” temperature display. If the desired temperature has
not yet been reached, the percentage must be increased. By setting percentages of the
heating duration, the temperature of the high pressure jet is kept constant in a very narrow
range. The last value set is also saved after the unit is switched off in percent mode.
Operating hour meter
The cleaner is equipped with an operating hour meter. If during normal operation the
momentary operating mode button ( “°C” or “%” ) is actuated for more then 2 seconds,
the operating time of the pump is displayed for 5 seconds and afterwards the combustion
time for 5 seconds as well. Thereafter the display shows the original values again. As
long as the operating hours are displayed no further inputs on the monitor are possible.
The operating time is displayed in hours [ h ] either in the “TARGET” or in the „ACTUAL“
window. The 1000 and 100 hours are displayed in the „TARGET“ window and the 10, 1
and 1/10 hours in the “ACTUAL” window:
Pump operating time: Target-Display: P 9 9 Actual-Display: 9 9. 9 for 9 999.9h
Combustion time: Target-Display: F 9 9 Actual-Display: 9 9. 9 for 9 999.9h
e.g.: F00 27.3 = Cumbustion time 27 hours and 18 minutes

Kränzle technology
Heat exchanger
The water is forced through a heating coil by the high pressure pump. Heating coil: 38 m
long - Content: 5 l of water - Heating capacity: max. 90 kW
The fuel pump draws the oil from the tank through a filter and pumps it to the injector
nozzle. The oil pressure is shown on the fuel manometer.
The heat exchanger is heated by a high pressure fan heater.
A ventilator draws in the cold, fresh air from the bottom end of the machine and forces it
upwards between the outer cladding and the inner cladding. In the process, the fresh air
is pre-heated and the outer cladding of the heat exchanger is cooled.
The pre-heated air is pressed through a mixing unit. Here finely atomized fuel is injected
via a nozzle and mixed with the air. The electrodes located below then ignite the fuel-air
mixture.
The flame burns from top to bottom, turns round and the hot gas flows past the heating
coil on its way back up. The burned gases collect in the exhaust chamber and are emit-
ted from the chimney.

Detergent and dirty fuel must be disposed of responsibly.
Adjusting ignition electrodes:
For a smooth ignition, the setting of the ignition electrode must be controlled regularly
(after 500 operating hours at the latest).
Fuel System:
Your fuel may contain particles of dirt, or impurities or water may get into the tank during
refuelling. To protect the fuel pump the machine is equipped with a fuel filter. Check this
filter regularly for impurities and clean if necessary.
Check the tank for impurities on a regular basis. Clean the tank when necessary. Empty
the fuel tank using the drainage screw at the bottom of the tank. Clean tank and fuel
pipes thoroughly. Screw drainage screw back in.

Suction of detergents
With detergent supply from the suction side:
Detergent injectiors on the pressur side, as you probably know from other HP cleaners,
consume approx. 30 % of the cleaning energy, no matter if they are used or not. Due to the
water tank fitted to the Kränzle therm cleaners it is now possible to directly suck the detergent into the pump thus reducing output loss and increasing the efficency considerably.
The detergents are applied without having to reduce the working pressure.
Only open the dosing valve, if the detergent sieve is placed in a liquid.
Sucked air leads to destruction of the pump seals! No guarantee!
Keep detergent-ph-value neutral 7 - 9!
Observe specifications of detergent manufacturer!
e.g.: protective equipment, rules for waste water treatment etc.
Never suck in liquids containing solvents like varnish solvents, 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.

Place detergent filter into detergent
container.
2.
Dosing of detergent is done by
turning the detergent valve switch into

Decommissioning - frost protection
01. Switch off the machine - main switch to „0“- position
02. Cut off the water supply
03. Open the spray gun briefly until the pressure is released
04. Apply the gun
05. Remove the water hose and spray gun
06. Drain the pump: switch on the motor for approx. 20 seconds
07. Pull the plug from the socket
08. Clean HP hose and wind up; fix drum
09. Clean water filter
Frost protection
The machine is normally still partially filled with water after work has been completed.
In case the cleaner is stored at temperatures below zero:
To protect the appliance from frost, completely empty it of water:
Disconnect the machine from the water supply and switch off the ignition. Switch on the
master switch and open the gun. The pump now presses the remaining water out of the
water tank, the pump and the continuous-flow heater.
Do not allow the machine to run for longer than a minute without water.
If the machine is not in use for lengthy frosty periods of time, it is advisable to pump
anti-freeze into the machine: For this purpose, fill the antifreeze agent into the water
tank and switch on the machine without heating. Wait with opened gun, until the agent
comes from the nozzle.
However, the best protection against frost is to keep the machine in a place that is
safe from frost.
Page 22

Care and Maintenance
Changing the oil:
First oil change after approximately 50
operating hours. Thereafter the oil should
be changed every 500 operating hours or
yearly.
Take the oil drainage hose, which is connected to the oil drainage screw from the inside
of the appliance.
Open the red oil ller plug at the top side of
the black oil housing.
Open the cap at the end of the hose. Drain
off the oil into an oil pan and dispose of it
responsibly. Close the end of the hose. Rell
with new oil
.
Weekly, or after approx. 40 hours of operation:
- Check the oil level of the high pressure pump. If the oil level is too low, add oil until
the oil level is between the two markings on the oil sight glass.
Change the oil if it has a grey or whitish appearance. The oil should be
disposed of responsibly.
- Check the water filter at the water inlet and in front of the float valve in the water
tank. Clean the filters if necessary.
Yearly, or after approx. 500 hours of operation:
- Check and decalcify continous flow heater, if necessary.
- Change the oil
Oil leakage: If oil leaks out, go to the nearest customer service (dealer) immediately. (Environmental damages, transmission damages)
In case of increased humidity or fluctuations in temperature
development of condensed water is possible; if the oil turns grey,
you must change it at once.
The machine must be disconnected from the power supply when servicing work is being carried out. The main switch should be in position „0“ and the plug out of the socket.
Page 23
23
Decalcifying the heating coil:
Calcified machines use an unnecessary amount of energy because the water can only
be heated slowly and the excess pressure valve feeds a part of the water back into the
pump circuit.
Calcified machines can be recognised by increased pipeline resistance.
Check pipeline resistance by disconnecting the high pressure lance from the gun and
switching the machine on. A full jet of water emerges from the gun. The machine must be
decalcified if the pressure shown on the manometer is above 25 bars.
Proceed as follows to decalcify the machine:
1.
Unscrew the high pressure hose from the machine and decalcify it separately.
2.
Put the detergent suction hose into a container of decalcifying solution.
3.
Turn detergent switch on.
4.
Switch on the machine.
5.
Aim the gun into a separate container and press the trigger.
6.
Wait for about a minute until the decalcifier comes out of the gun
(recognisable by its whitish colour)
7.
Switch off the machine and allow the solution to act for about 15-20 minutes.
8.
Switch the machine back on and rinse it through with clear water for about 2 minutes.
9.
Now check whether pipeline resistance is back to an acceptable level.
Repeat the decalcifying process if the pressure without the high pressure lance is
still above 25 bars.
Decalcifiers are caustic! Observe the instructions for usage and accident prevention. Wear protective clothing to prevent the decalcifying
agent from contacting your skin, eyes and clothing (e.g. gloves, safety mask etc.)

Excess temperature release
As an additional safety device the appliance is equipped
with an excess temperature sensor inside the chimney. Should
the safety devices as e.g. the float monitoring device be defectice and the burner continues to heat although the heating coil
does not conduct away heat a destruction of the heating coil
would be inevitable. As soon as the temperature inside the
chimney exceeds 260 °C the excess temperature release triggers and cuts out the appliance.
The display of the excess temperature release is located on the
back of the switchbox inside the appliance.
RED:
Excess temperature released, let appliance cool down, no hot water operation possible
YELLOW: Appliance cooled down, activation of hot water opertion possible by pressing
the RESET-button.
ATTENTION !!!
Immediately contact service in case of recurrence!

Troubleshooting
Hot water mode
The fuel manometer shows the fuel pressure.
If no pressure is shown, check if
- there is heating oil in the tank.
- the fuse in the electric box (below the operating panel) for the motor has blown.
- the fuel sieve or the fuel sieve in the pump is dirty.
- the fuel pump does no operate smoothly or is blocked.
- the ventilator jams.
The thermostat grants permission to open the solenoid valve. The burner starts and
heats the water to the temperature preset by you. As soon as the temperature is reached the burner switches off.
If the temperature drops again, the burner switches on automatically, so that the desired
temperature is constantly kept.
The thermostat is controlled by a thermosensor, mounted to the outlet of the heating coil.
In the electro distributor box (below the operating panel), there is a fuse (circuit diagram
F1) on the PCB which protects the motor for fuel pump and ventilator. If the motor is
overloaded, the fuse blows. This can happen when the fuel pump is blocked or does not
work freely, when the ventilator is blocked or does not operate freely or when there is an
electrical problem.
A second fuse (circuit diagram F2) on the PCB triggers, if the ignition transformer is faulty.
The transformer on the PCB is protected by two fuses (32 mA, 630 mA).
To avoid an overheating of the combustion chamber, a flow monitoring device is installed
between high-pressure pump and combustion chamber, which only permits fuel injection
if water is running through the heating coil at the same time.

Small repairs
do it yourself!
No water from the nozzle but the gauge
shows full pressure: Most likely the nozzle
is blocked. (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 gun seveal times to decrease
the pressure. First unscrew gun and lance, then rinse
hose from any residues. Check water inlet filter for
soiling. If the problem still exists, take wire (paper
clip) and push cautiously through nozzle opening. If
this procedure is not successful, the nozzle has to be
dismantled and cleaned (from the backside) or even
replaced, if necessary.
Pressure gauge shows little pressure, the
water from the nozzle comes in squirts.
The high-pressure hose vibrates.
Most likely the valves are soiled.
(Inside the pressure gauge is no water but a filling
with glycol to damp the vibration of the pointer).
Proceeding:
Unscrew all 6 valves, one after the other
(hexagonal brass screws, 3 in a row,
vertically and horizontally)
Take out valve body (with green or red plastic
coating) and O-ring by means of needle nose
pliers. Check O-ring for damage. In case of a
damage the O-ring has to be replaced.
Take a wire (paper clip) and clean valves under
running water. Also clean valve seating inside the
pump.
Do not forget the O-ring during reassembly!
Page 33
33
The pressure gauge shows full
pressure although the gun has been
closed. The pressure switch valve
switches constantly.
Possible cause no.1: Leakage
Having closed th gun, the HP cleaner must shut
down and the pressure gauge must show „0“
bar. If the pressure gauge still shows full pressure and the motor constantly switches on and off,
the possible reason for this can be a leakage of
the pump, the HP hose or the lance.
Proceeding:
Check the connections from the HP cleaner to
the the HP hose, from the hose to the gun and
also the connection between lance and gun for
tightness. Switch off the cleaner. Shortly press
the trigger of the gun to decrease the pressure.
Unscrew HP hose, gun and lance and check the
O-rings. If the O-rings are damaged they have to
be replaced.
In case of a leakage there is no guarantee for
possible consequential damages.
Possible cause no. 2:
The non-return valve is soiled or defective
Proceeding:
Unscrew pump outlet.
Take out non-return valve body and check for
soiling or damage of the O-ring.
Replace non-return valve if necessary.
There is no guarantee if the pump is
damaged by defective O-rings due to air
induction or lack of water (cavitation).
