General rules
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 42-43.
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 8 and 9).
Oil change:
The first oil change should be carried out after approximately 50 operating hours. After
that no further oil change will be necessary for the life cycle of the high-pressure
cleaner. If it becomes necessary during repairs, or because the oil has a greyish colour
to perform an oil change, 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 manner. New oil: 0.25 l - Motor oil: W 15/40.
Oil leakage: If oil leaks contact your nearest after-sales
service (dealer) at once. (Ecological 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, you must change it.
Safety precautions
7
Bear in mind that during cleaning tasks
with a high-pressure water jet a significant
recoil at the lance arises. Please stand
firmly. (see technical data on page 4).
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!
8
Safety precautions – This is prohibited!
Never direct the water jet at people
or animals!
Only use pow er cables which are
in perfect w orking order! Do not
damage the p ower cable or repair it
incorrectly!
Never pull t he high pressure hose
if it has for med kinks or “ nooses”!
Never pull t he hose over s harp
edges!
Never allow children to use the high
pressure cleaner!
Never direct the water jet at the
machine itself!
9
The machine may not be placed within
reach of the water jet spray mist!
Never direct the water jet at a power
socket!

Please note - important:
Lack of water
If the metered quantity of water is too small, you have to use a
different water connection, guaranteeing the necessary output.
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
.
A minimum water quantity of 10 litres
per minute must be available to
guarantee a trouble-free operation of the
Kränzle 1151 T/1151.
Lack of water leads to an accelerated wear of the joints
(no guarantee)
Connection to 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 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.
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.
Kränzle 1151 T/1151:
230 V ~, 12,0 A, 50 Hz
Check the line fusing and have the voltage and the available current
intensity checked by an expert in case of uncertainty.
11
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 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
Kränzle technology
Wasser and cleaning system
Water can be connected at mains pressure (1-8 bar pre-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.
Environmental, refuse disposal and water protection
regulations must be observed!
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. 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.
The increase in pressure when the trigger gun is closed 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 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.
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.
.
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 11).
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 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 (without leakage).
The high pressure hose may not be driven over, pulled
excessively, or twisted.
The hose may under no circumstances be pulled over
sharp edges.
Defective high-pressure hoses must not be repaired (acc. to
DIN 20022) but have to be replaced by new hoses appoved by
the manufacturer.
Total stop system
Kränzle 1151 and 1151 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
gun is operated. If the trigger is released the motor is switched off at once.
