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 pressure
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
operating 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
pressure spraying from the lance.
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.
Unloader valve - safety valve
The unloader valve - safety valve protects the machine from a build p 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.
*(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 qualified 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
rectified (see page 6).
Motor protection switch
Setting up
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.
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 inflammable, 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
without safety gloves!
Replacements and inspection work should only be performed by
qualified 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 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 HD 7/120 230 Volt / 50 Hz
KRÄNZLE HD 10/120 230 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 floor.
(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 difficulty.
When using a cable drum, always keep the cable wound as far as possible.

Description
Please check that the high pressure cleaner has available the quantity
of water specified on page 2 (techn. specifications) (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 accordance
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 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.
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
under no circumstances be pulled over sharp edges,
since otherwise the guarantee is automatically void.

Safety notes
As to the recoil -
see notice on page 2!
Always aim the
underbody lance. Note
when using an angled
underbody lance, like
forexamplelanceno.
41.075 1, that there is a
certain amount of
torque in the recoil.
(Amount of torque 26
Nm)
Apply the safety catch on the
spray gun after each use, in
order to prevent uninten-
tional spraying!

Ensure that the water supply is
clean when sucking from external
sources.The hose cross section
must be at least 1/2" = 12.7 mm (free
passage). Filter 1 must always be

Small repairs -
18
Nozzle dirty or sticky!
Pressure gauge does not show full pressure.
Water comes out in spurts.
If you do not use the high-pressure cleaner
for some time the valves can stick
The high-pressure
hose vibrates.
Straighten a
paper clip...
When a valve is blocked, the gauge
shows little
pressure or
no pressure
at all,
or the high
pressure
hose vibrates!
Open the valve
with a socket
wrench...
and remove the
valve screw, the
valve and the
o-ring.
Replace the rubber o-ring.
and remove the dirt
from the valve - the
valve inside must
be closed.
Retighten the
valve screw
...and repeat
on all 6
valves.
Now it works
as well as
before!

19
The nozzle is blocked!
No water but the gauge shows full pressure !
- Do it yourself!
Rinse the hose through
first. You should now have a
powerful stream of
water,
but if you
only get a few
drops from
the lance
remove the lance and clean
the nozzle.
Using the flat spray lance you
only have to clean the
front nozzle.
Straighten a paper
clip and clean the
nozzle.
Insert pointed object
into the hole and pull
the cap back!
Check visually whether the
nozzle is clean. Now it works as well
as before.

20
Small repairs - Do it yourself!
Stopping leaks from hose or gun
After closing the gun the manometer shows full pressure !
The pressure regulator switches on and off continuously!
If the
manometer
shows full
pressure,
Press the
trigger to
release the
pressure!!!
First
disconnect
the hose!
Then unscrew the
pump outlet with an
open-jew wrench.
Clean the return
element or replace
the O-Ring !
The pressure
regulator
switches on
and off from
pressure
loss!
Water can emerge at
these 3 points.
Check the seals and
replace the O-Ringe if necessary
or ave the gun checked by the dealer.
Replace the O-Ring
at the lance or at the
HP hose respectively!
Reconnect
the hose, gun
and lance!
Problem
solved already!
Pull out the
power plug!
