seals. Always turn the water on before
starting the machine;
� To prevent accidental discharge of
high pressure water, the trigger safety
lock must be engaged whenever the
machine is not in use;
� When the machine is under pressure
and the trigger is pressed, the release
of pressure may cause gun recoil.
Adopt a stable and firm posture. Hold
the gun firmly with both hands to
prevent accidents.
� Do not use the machine with other
people nearby without protective
equipment;
� Never point the water jet towards
people, animals, other machines and
electrical systems;
� Do not put you hand, fingers or body
in front of the sprinkler nozzle. The jet
may hurt you;
� Keep the pressure hoses connected
to the machine and gun while the
system is under pressure. Make sure
the machine is off and with no pressure
before connecting the hoses;
� Do not use the machine to pump fuel
or other flammable liquids;
� Use the pressure hoses, fixations
and fittings according to the technical
features and manufacturer’s
recommendations. These accessories
are important to guarantee safety;
� Do not use excessive pressure.
Make sure every accessory bear the
maximum limit;
� Tyres and tyres’ valves may be
damaged by the high pressure jet and
cause bursts;
� Before starting to operate the machine
in cold climates, make sure that there
is no ice on any component of the
machine;
� It is not allowed to clean surfaces
containing asbestos;
4.1 - START (FIG. J)
The machine is equipped with
an automatic START/STOP
system, based on water pressure. The
machine motor does not run
continuously. It operates only when the
gun trigger is pressed. Each time it is
released, the machine stops
automatically.
1. Check if the machine is in a vertical
position;
2. Open the tap where the hose is
connected;
3. Remove the trigger safety lock (27)
to enable the start-up;
4. Press the gun trigger (6) until the
pump and supply hose is air free;
5. Connect the power cable (15);
6. Set the “ON/OFF” switch (10) into
position (ON);
7. Press the gun trigger start operating
the machine;
Always turn on the water supply
tap before turning the machine
on. Operating with the machine with no
water will cause serious damages.
4.2 - STOP (FIG. K)
1. Release the gun trigger (6);
2. Set the “ON/OFF” switch (10) into
position “OFF”;
3. Close the tap where the water supply
hose is connected;
4. Press the gun trigger to relieve the
pressure;
5. Move the safety lock (27) to lock the
trigger;
6. Wind the high pressure hose (20)
and place it in the support (13);
7. Detach the quick connector from the
supply hose;
8. Wind up the supply hose;
9. Unplug the power cable (15);
10. Wind up the power cable and place
it in the support;
Never close the water supply
tape before turning off the
machine.
4.3 - WATER OUTLET PATTERN
REGULATION (FIG. L)
The water outlet pattern regulation is
carried out through the sprinkler nozzle
(2).
1. Rotate counter clockwise for a
thinner pattern;
2. Rotate clockwise for a wider pattern;
Always release the gun trigger
(6) while regulating the water
outlet pattern.
A thinner jet produces a stronger
impact that results in a deeper cleaning
in a specific area. This type of jet must
be used carefully once it might cause
damages in some surfaces.
A wider jet distributes the water impact
over a larger surface, cleaning a bigger
area and being less likely to cause
damages.
The water outlet angle can be adjusted,
allowing an outlet pattern between
0° and 60°. Using an outlet pattern
equal to 45° allows an efficient debris
removal, due to the combination:
impact force and jet action area;
Another factor that determines the
water impact force is the distance
between the sprinkler nozzle and the
surface to be cleaned. The impact force
increases as the nozzle approaches the
surface.
