3.2. Technicians or maintenance technicians are obliged to notify any possible defects or
deteriorations that are able, in any way, to compromise the original safety of the plant.
3.3. The serial high pressure cleaner is not equipped for working in environments characterized by
particular conditions of inflammability or explosiveness; flameproof equipment is supplied only
and exclusively on specific request. It is forbidden to install the high pressure cleaner in
environments where inflammable materials are present or with particles it suspended in the air:
acids, inks, varnishes, resins, solvents, plastic subjects, etc.; follow the norms imposed by the
fire department.
3.4. During the filling of the fuel tank, the high pressure cleaner must be disconnected from the
electric net. At the same time it is absolutely forbidden to smoke or approaching the machine
with free flames during the filling of the fuel tank.
3.5. The hot water high pressure cleaners are projected for an economic combustion, clean and
respectful towards the environment and deprived of the residual exhaust gases. Despite this,
inhaling high quantity or percentages of gases, such CO, is harmful and lethal particularly.
3.6. If the high pressure cleaner is installed or used in places and closed (like garages or
establishments) environments, it is necessary to predispose a device of evacuation of the gases
together with a recycling of the air supply and for the restoration of the air in the place or in the
closed environment.
3.7. Never obstruct the terminal of the chimney; with objects, lance or gun, in proximity of the outlet
of the smokes. It’s also considered highly dangerous, both for the smokes and also for the
elevated temperatures reached. To avoid possible burns, inform technicians and operators
about it.
3.8. The high pressure cleaner and its plant as the place and the environment, are forcedly exposed
to the water and the damp that injure the natural conditions of isolation of the plant. Don't use
therefore unsafe electric cables, thorns or plugs, and sockets; to check the integrity and the
isolation of the electric cable, together with the equipment of the operators. Don't absolutely
touch the thorn or the plugs with wet hands or feet. To avoid accidental switching on, turn the
interrupter on OFF before inserting or disconnecting the power supply. Don't pull the high
pressure cleaner using the electrical or to extract its thorn from the socket.
3.9. Use with extreme care the chemical detergents not to deteriorate the environment (degradability
90%), parts or components of the machine, according to the updating of the legislative decree.
Besides, always check the degradability and the aggressiveness of the used detergents. Never
use acids, inks, solvents, liquid oily, varnishes, resins, etc…
3.10. The "cold" starting of the high pressure cleaner can cause some serious damages to the pump
and the circuits; the standstill prolonged at temperatures under 0°C could cause breakups and
damages to the pump and the pipes; therefore the emptying of the machine is advisable.
3.11. Always protect the high pressure cleaner from the atmospheric agents, from the cold and from
the frost.
3.12. Never direct the jet of water towards people (not even to clean their clothes or their shoes) or
animals, nor the machine itself or any objects under electrical tension.
3.13. Lance and gun, although equipped with proper hilts, they have a modest counterblow to the
departure of the jet; to maintain them with strength with both the hands. Do never touch the jet
of water during the operation of the idropulitrice.

6. Transport and unpacking
6.1. Submit lifting and transport to
specialized personnel. To protect the
machine, especially during the
transport on road, from bumps, damps
or from vibrations, etc…; the high
pressure cleaners are climbed on
wheels and therefore they must firmly
be anchored before the beginning of
the transport. To underline the
dangerousness in the moving of the
suspended loads, operators must be
warned about risks to collisions.
6.2. To unpack the high pressure cleaner,
verify the one is not damaged and has
got all the parts and components. In
the case in which the machine is
damaged, please call the supplier and
do not use the machine. We remember

that the elements used in the high pressure packing could to hurt the operator if not handled
with care. These packings must be digested therefore and not left to the course of children or of
irresponsible persons. The same is worth for the objects used in the removal of the unpacking
pack (knives, scissors.). For tied up demands to unpacking and to the transport, some
components are supplied not installed; proceed therefore to the installation according to the
instructions of the manual.
7. Installation
7.1. Control carefully that the environment for the installation of the high pressure cleaner
considering all the foreseen and unforeseen possibilities. The machine is equipped with insane
wheels, therefore it is unadvisable to position, without precautions, on tilted surfaces. Do never
tilt the high pressure cleaner to more than 20° when the tanks are full.
8. Connection to the electricity supply
8.1. The high pressure cleaner can be connected to alternating single phase (230V) or three phase
(400 V) with frequency 50hz. For the three phase models, the high pressure cleaner is normally
supplied connected to 400 V, although can be in demand connected to other connections (for
instance 230v).
8.2. For the maximum absorption of the electricity, compare the underlying chart.
8.3. Verify that the electric net, to which the machine is connected with the electric cable, has the
appropriate characteristics.
8.4. The high pressure cleaner is endowed with a magnetothermic switch that interrupts the power
supply in the case the absorption of the supply overcomes the value of the setting; for the
location of the switch, take a look to the electric plan attached to the machine.
8.5. The client buyer is kept to subsequently protect the line of the power supply by installing a
lifesaver with a load not exceeding 30A.
8.6. The cable is supplied without plug for the connection to the net: this must be installed by the
buyer, which will verify that:
8.1.1. The plug is proper for the data of the voltage and the tension above described;
8.1.2. The plug is conforming to the norms in force in the nation of installation and use and that
in any event it is earthed.
8.1.3. The connection cable and plug connection is waterproof.
8.1.4. If a cable with extension is used, this must have a minimum section of 2,5 mmqs if the
cable is long up to 20 mt, or of 4,0 mmqs if the cable has a superior length than 20 mt.
The flying thorns and plugs are forbidden: to use some cablereels.
8.1.5. If the cable of the connection is damaged, this must be immediately replaced with a
proper cable: such operation must be performed by specific and authorized personnel.

9. Connection to the water supply
9.1. The pressure of the water supply must be at least 2 bar. If the pressure is insufficient, the pump
will inhale air and will be subject to overheating and vibrations with serious damages to the
pump and the car.
9.2. The water supply must provide a flow of water of at least of the 10% of the course of the high
pressure cleaner (compare the chart with technical characteristics).
9.3. First of all, connect the water supply tap to the machine input pipefitting IN, using a hose with
proper diameter, whether to connect the lance to the link of exit OUT.
9.4. For a long duration of the pump, and to avoid the use of water containing sand or other particles
that jeopardize the efficiency of the valves and of the pistons or of the gaskets. To such purpose
it is advisable to apply a filter to the pipe of suction to great surface and low loss of load,
handling periodic substitution.
9.5. When the machine is equipped with a special tank, it is convenient to install a filter upstream of
the tank: the pipe of water feeding must have a diameter not smaller than the link of the
connection to the machine and must be prepared in such way to avoid that possible airlocks are
formed.
9.6. The water supply can have a maximum temperature of 60°C and a maximum pressure equal to
8 bar. The gaskets and other parts and components of the pump could be irremediably
damaged when the machine is made to work without of water, even if for short periods. Verify
that the tap of the water supply is completely open before the high pressure cleaner is switched
on.
OPERATION
10. Switching on
10.1. To bring the interrupter in position 1 and to maintain the thermostat to the least (rotated
counterclockwise in sense) one.
10.2. To act on the trigger of the gun (hilt) on the lance, maintaining her/it with strength to
compensate its counterblow and making to work the car for 2 or 3 minutes: this allows to bait
the pomp and to eliminate possible residues that could clog the nozzle; The trigger of the gun
has a sure that prevents the accidental activation of the throw. To insert the sure one when the
lance is not used. In this condition the car works to cold water.
10.3. In the case in which a detergent is used, to insert him/it in the reservoir on purpose predisposed
to the purpose and to open the faucet.
10.4. For the water operation warm, to rotate the thermostat to regulate its temperature.
10.5. To press the interrupter.
11. Switching off

however turned on and available to the use: to stop therefore the safety catch on the trigger.
11.2. To switch definitely off the machine, turn the switch on O; if the machine has worked with hot
water it is opportune, before switching off the switch, to lower the temperature, that is to rotate
on 0 (in sense counterclockwise) the thermostat and letting work the high pressure cleaner with
cold water for about 2 minutes, to cool the coil.
11.3. For prolonged stand-by, before turning off the machine, it’s necessary to cool the coil as
previously clarified: close therefore the tap of the water supply, operating on the trigger, so that
to unload completely the water from the circuit. This procedure is advisable especially in places
with temperatures go under zero.
11.4. As soon as the water flow stops, switch the machine off by acting on the switch.
11.5. ATTENTION: the operation of the pump in absence of water could irreparably damage the seals
of the pomp.

12. Maintenance
12.1. It is absolutely forbidden to effect controls or operations of maintenance with the machine
operating or under tension: always remove the electricity supply!!! Don't even effect reparations
of fortune or precarious, and never use non-original spare parts.
12.2. The operations of extraordinary maintenance and the control of the combustion must regularly
been realized by specialized personnel.
13. Pump
13.1. The pump is equipped with three pistons in ceramics with automatic recovery of possible
leakages.
13.2. If a persistent dripping is noticed under the body of the pump, replace the piston waterproofing
seals. Nevertheless, in the first hours of exercise, a small loss points out only and exclusively an
arrangement of the seals and not a breakdown.
13.3. If there are some losses of oil between the body of the pump and the head of the pump, it is
necessary to remove the oil, to get off the head and to handle the substitution of the seals of
the head. For this operation it is necessary to contact a specialized and authorized assistance
center.
13.4. Restarting the pump after the maintenance to verify that this is supplied of oil. The oil must be
replaced after the first 50 hours of operation and subsequently every 200 hours of operation;
the ability of the reservoir of the oil is equal to 0,55 liters. Use only and exclusively oil with brand
Esso Plus Motor Oil 20W30 or Shell Oil X100 20W40.
