1MAIN COMPONENTS (Fig. 1)
We wish to thank you for choosing our machine. We are confident that the high quality of our machine will meet with your
satisfaction and appreciation and that your pressure washer will give you long-lasting service. Before starting to use your
machine, make sure to read with care this manual, which has been purposely drawn up to provide you with all the necessary
information for proper use of the machine, in compliance with basic safety requirements

2SAFETY PRECAUTIONS
The high pressure of the water
generated and connection to the
electricity supply constitute
particularly serious danger risks.
Carefully read the user
instructions before starting
the machine for the first time.
Follow the safety warnings.
The appliance must be used solely by personnel trained
in its use and specifically authorized to use it.
The user manual must be made available to all users.
Do not subject the machines to any modifications
which may jeopardize personal safety.
Using extensions, check the minimum section of the
individual cables (see paragraph entitled “Connection
to the mains appliances”).
Install the extensions in such a way as not to alter the
protection class of the appliance.
In the event of the use of extensions, the plug and
socket must be of waterproof type.
The use of unsuitable extension leads may constitute a
danger risk.
Your electrician can give you the necessary
information on the protection classification.
The electrical system to which the appliance is
connected must be realized in compliance with the
laws of the country of installation. The presence of a
differential magnetothermal switch is necessary with
a sensitivity of equivalent to 30 mA, above the power
socket or the system.
Only put the appliance into operation providing that
all components are free of defects.
Firstly check the mains attachment wire, the high
pressure pipe, the spraying device and the body.
Do not tread on the high pressure pipe; do not pull,
bend or twist it.
Do not shift the appliance by pulling it by the high
pressure pipe.
Never operate with a defective high pressure pipe,
but always replace with original spare.
The high pressure pipe must be homologated for the
permitted working overpressure of the appliance.

Do not use the device in the
vicinity of persons, unless they
are wearing the necessary
protective garments.
High pressure jets may be
dangerous if used incorrectly, the
jet must never be directed on
persons, live electrical appliances,
including the appliance itself.
Never use the jet to clean your
own garments or footwear.

printed on the high pressure pipe covering.
Use only slightly alkaline detergents (Ph 9.1, 1%
solution), that are over 90% biodegradable.

CLOTHING AND EQUIPMENT
Always wear anti-slip sole
footwear.
Wear protective goggles or
visor and safety wear.
It is advisable to wear work overalls in order to redu-
ce the risk of injury in the event of accidental contact
with a high pressure jet.
FIELDS OF APPLICATION
The high pressure water cleaner has been developed for
washing vehicles, machines, containers, façades, stables
and for removing rust without generating dust or sparks.
During cleaning, ensure that no dangerous substances
of the object to be cleaned are dispersed into the
environment (such as asbestos, oil for example).
Carefully follow disposal instructions.
Do not treat concrete-asbestos surfaces with high
pressure jets. As it may cause the detachment of
dangerous asbestos fibres as well as dirt, detrimental
to the lungs.
The risk exists particularly after the drying of a surface
treated with a water jet or steam.
Do not clean delicate components made of rubber,
fabric or similar materials with a multi-directional jet.
When cleaning with a high pressure, flat jet, keep the
nozzle at a minimum distance of 15 cm.
STARTING UP, OPERATIONAL ADVICE
The trigger of the spray gun must
function smoothly and return to
initial position, after release.
Check the functional conditions of the appliance
before the start of each operation.
The mains cable and the plug, the high pressure pipe
with spraying device and the safety devices are
particularly important.
Keep children and animals clear when the appliance
is operating.
WARNING : with gun closed, on
machine not fitted with TOTAL
STOP system, avoid operating the
water cleaner for more than 30
minutes at a time to reduce the risk
of damage to the sealing system
of the water cleaner itself.
Before undertaking any
work on the appliance
always detachthe plug from
the power socket.
Do not ever wash the appliance or other
electrical appliances with a water jet.
Short circuit danger !
Check that there is sufficient air circulation in the
motor ventilation zone.
Do not cover the appliance, ensure
that there is sufficient motor
ventilation.
Position the high pressure cleaner as far away as
possible from the object to be sprayed.
Do not damage the mains attachment cable by
treading on it, squashing or pulling it, etc.Do not
detach the plug from the socket by pulling the
connection wire, but pull out the plug.
Make sure hands are dry before touching the plug
and the connection cable.
Hold the spraying device with both hands in order to
properly absorb the reaction force and the additional
torque in the case of spraying device with an inclined
spraying pipe. Always assume a safe and secure position.

3WALL INSTALLATION
As concerns water connection, refer to the regulations
of the individual countries.
The constructor will not accept liability for any damage
to people, animals or things as the result of improper,
incorrect or unreasonable use, or use which does not
comply with the above indications.
The water cleaner must not be used by children or
untrained persons.
Use only flexible hosing, accessories and fittings
recommended by the manufacturer. Do not use the
appliance in the event of any damage to the power
cable or other parts such as piping and fitting.
IMPORTANT : Use only original Spare Parts
Fix the supporting bracket to the wall, by making
holes having a diameter of 12 mm at a height from
ground of approx. 180-190 cm (fig. 2). Make sure
that the wall and the fixing screws (included in the
supply) are suitable to support the weight of the
machine (Kg 40).
Release the gun from the high pressure pipe after
unlocking the safety device (fig. 7-B).
Connect the machine to the previously fixed bracket
and make sure that hook (1) is properly placed in the
eyelet on the upper part of the machine (fig 3). Then
fix the machine on the bracket by screwing the two
screws included in the supply.
Make two additional holes (Ø 12 mm) near the bracket
placed under the pipe winding device and fix the
machine to the wall using fixing screws included in
the supply (Fig. 4).

It is advisable to point out the correspondence of the
holes: remove the machine from the bracket and
make the holes in such a way as to conveniently
work with the drill.
After definitely fixing the machine to the wall, intro-
duce the high pressure pipe into the loop under the
pipe winding device (Fig. 5); then fix the holder
bracket for accessoiries as shown in fig. 6.

10 MAINTENANCE , REPAIRS AND STORAGE
Before undertaking any work on the appliance always detachthe plug
from the power socket
Undertake only the maintenance operations described in the user instructions.
Contact the Technical Assistance service for all other interventions.
Use only original spares.
Should the power cable be damaged, it must be replaced by a cable or a set of special cables available from
the manufacturer or its assistance service.
The pins and joints of the connection cables of the electrical system must be protected against accidental water sprays.
STORAGE
Store the appliance in premises protected against freezing conditions.
If freeze protection is not guaranteed, suction a glycol based anti-freeze into the pump, as for cars
- Immerse the water pipe into the container of anti-freeze
- Immerse the gun without the sprayer nozzle into the same container
- Insert the appliance with open gun
- Activate the gun until an even jet is obtained.
Store the rest of the anti-freeze in a closed container.
