Water- and cleaning/detergent system
Water can be connected at mains pressure to the high pressure pump or it can
be sucked directly from a storage tank. The water is then forced under pressu-
re by the high pressure pump to the lance. The high pressure jet is formed by
the nozzle at the end of the lance.
Lance with trigger gun
The machine can only be operated when the safety trigger is squeezed. 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 opera-
ting pressure.
When the trigger is released, the trigger gun closes and any further spraying of
liquid from the lance is stopped.
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 trigger gun is
opened, the unloader valve - safety valve closes and the pump ressumes pres-
sure spraying from the lance.
The trigger 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 manufactu-
rer.
Unloader valve - safety valve
The unloader valve - safety valve protects the machine from a build p of ex-
cess pressure, and is designed not to permit an excess pressure to be selec-
ted for operation. The limit nut on the handle is sealed with a spray coating.
*(see page 22:“Stopping leaks from the hose or gun“.)
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.

Description
The motor is protected from overload by a motor protection switch, which
automatically cuts out the motor in the event of overload. However should the
switch trip frequently, the cause of the malfunction should be located and recti-
ed (see page 6).
Motor protection switch
Setting up
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.
Never use 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ammable, explosive and poisonous.
CAUTION !
CAUTION !
When running your high pressure cleaner with hot water of 60° C
raised temperatures occur. Do not touch the machine with-
out safety gloves!
Replacements and inspection work should only be performed
by qualied persons when the machine is disconnected
from the power supply, i.e. pull out the plug from the
electrical socket.
Location

Electrical connection
The machine is supplied with an electrical power cable with plug.
The mains plug must be tted 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 HD 7/122 230 Volt / 50 Hz
KRÄNZLE HD 10/122 230 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 spray-proof design, and may not be
located on a wet oor.
(with extension cables of more than 10 m - 2.5 mm2 )
CAUTION !
The use of extension cables which are too long may lead to malfunctions and
start up difculty.
When using a cable drum, always keep the cable wound as far as possible.

Please check that the high pressure cleaner has available the quantity of
water specied on page 2 (techn. specications) (Litres per minute).
Water connection:
Test:
Allow the water to run through the supply hose into a bucket for 1 minute.
The received quantity of water must be at least the quantity given on page 2 !!!
Lack of water causes fast wear on seals (no warranty)

Brief operating instructions
When operating your high pressure cleaner
pay attention that it is in a horizontal position.
1.Connectthehighpressurehosewiththespraygun.
2.Connecttosuitablewatersupply.
3.Flushtheairfromthepump(openandclosethespraygunseveraltimes)
4.Maketheelectricalconnection
5.Switchonthemachinewithopenedspraygunandcommencecleaning.
6.Aftercompletingthework,completelyemptythepump(switchthemotor
onforapproximately20secondswithoutthesuctionandspraygun).
 -Onlyusecleanwater!Protectfromfrost!
CAUTION !
Please pay attention to the regulations of your waterworks company. In accord-
ance with EN 61 770, the machine may not be directly connected to the public
drinking water supply lines.
A brief connection however is permissible according to DVGW (German Associa-
tion 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 oat valve.
Direct connection to a non-drinking water supply line is permissible.
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.
- Hose length max. 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 regula-
tions may be used. The high pressure hose and spray device must be connected
in a pressure-tight manner (no leak). The high pressure hose may
not be driven over, pulled excessively, or twisted. The hose may un-
der no circumstances be pulled over sharp edges, since otherwise
the guarantee is automatically void.
