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 49 - 51.
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:
Oil leakage: If oil leaks out, contact nearest customer service (dealer) immediately. (Environmental damages, transmission damages, loss of guarantee). In case of increased
humidity or fluctuations in temperature the formation of
condensed water is possible; if the oil turns grey, it has to
be changed immediately.
Oil drain screw
(View of appliance from below)
The first oil change should be carried out
after approximately 50 operating hours,
then every year or after 1000 operating
hours. Open the oil drain screw at the bottom of the device over a collection resevoir. The oil is to be caught in the reservoir
and disposed of in an approved manner.
New oil: 1,0 l - Motor oil
10/W-60 SAE semi-synthetic oil

Safety precautions
Always bear in mind that during cleaning
tasks with a high-pressure water jet a
significant recoil at the lance arises (see
technical data on page 4 and 5).
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!
9
Safety precautions – This is prohibited!
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!
10
Never allow children 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!
Safety precautions – This is prohibited!
11
That's what you have to observe
!
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 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
half a minute
.
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.
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
(no guarantee).
The following minimum quantity of water
is necessary for a safe and problem-free
operation of the high-pressure cleaner
:
Kränzle quadro 1500 TS T 25 l/min = 12.5 l/1/2 min
Insufficient current intensity
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. Consequent ly 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 malfunct ions or start-up difficulties.
Connected load: 400 V, 12 A, 50 Hz
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.
Kränzle
quadros: 400 Volt, 50 Hz
. 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 sprayproof 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.

Kränzle technology
Water and Cleaning System
The water must be lead to the high pressure cleaner under pressure (2 – 8 bar admission pressure). A float 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.
Bypassing the water tank enables the cleaner to suck in water directly from a pressureless container. (see page 20)
Environmental, refuse disposal and water protection
regulations must be observed!
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 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 spray gun is closed causes the pressure control
valve-safety valve to open. The motor is switched off by the pressure switch. When the
spray 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.
14
Delayed motor cut-out
Frequent, work-necessitated switching on and off of motors on machines of this size puts
a heavy load on the power network and causes increased wear on internal electrical
parts. Therefore the motor of the Kränzle quadro device only switches off 30 seconds
after closing the gun and then goes to stand still. By opening the gun, the device is
started again.
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.
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. The high pressure
hose may not be driven over, pulled excessively, or
twisted. The hose may under no circumstances be pulled
over sharp edges.
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.
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 cuts off from the power supply system (safety state). By
operating the main switch once more, the device is activated again.
15
