7. USING THE HIGH PRESSURE CLEANER
START-UP
After checking that the operations described in paragraph "6" have
been carried out, relative to start-up, it is necessary to proceed as follows:
• open the tap for the hydric system;
• start-up the high pressure cleaner, pressing the switch button to
the
position;
• press the spray gunl lever, gripping it firmly, and direct the water
jet towards the surface to be cleaned.
HOT WATER START-UP
• Carry out the operations described in the previous paragraph;
• also check that the temperature adjustment handle is in the posi-
tion corresponding to minimum temperature;
• turn the burner switch to position
• adjust the temperature knob to the position desired.
INTERRUPTION
The machine is equipped with a delayed total stop device; hence, if
the pistol lever is released, the exit of water is immediately interrupted,
while the pump-motor continues to rotate for approx. 40 seconds, after
which the group stops. The high pressure cleaner automatically restarts
normal functioning when the spray gun lever is pressed. During the 40
seconds, of stand-by the water is allowed to recycle, with supply pres-
sure, in the by-pass circuit, but it is possible to easily and quickly
restart washing without overloading the motor with frequent start and
stop cycles. In addition, the timing of the "machine stop device" pro-
tects the pump since it prevents the seal gaskets from being damaged
by water that overheats due to excessively long recycling.
STOP
To stop the high pressure cleaner from functioning, it is necessary to:
• rotate the temperature adjuster to the minimum value (after hot wa-
ter use);
Attention
Operate the pump for at least 2 minutes with cold water,
keeping the handle lever pressed, in order to allow the
coil and combustion chamber to cool down.
• press the switch button to the "OFF" position;
• shut off the water supply;
• discharge the residual pressure in the circuit, keeping the water
jet lever pressed until the water jet finishes;
• lock the spray gun, to avoid any involuntary water action;
• disconnect the plug from the electricity socket.
WASHING WITH DETERGENT
The injection of detergent product is carried out at low pressure: ro-
tate, in a clockwise direction, the adjustable nozzle head (position ON);
The quantity of detergent can be pre-adjusted by opening or closing the
detergent batcher located on the hydraulic circuit immediately after the
By-pass valve. When completed, rotate, in an anticlockwise direction, the
adjustable nozzle head (position OFF) and close the detergent batcher
(see Fig. 5).
To obtain effective washing, carefully spray the detergent, allow it
to act for a few minutes and, afterwards, thoroughly rinse with a high
pressure jet of water.
WASHING WITH DEVICE FOR HYDROSANDING (Optional Accessory)
By applying the device for hydrosanding to the high pressure
cleaner, it is possible to wash and clean surfaces covered by rust, paint
or hard incrustations.

The device for hydrosanding is easy to apply (see Fig. 6): simply
replace the standard lance with the lance for hydrosanding (1) and
place the sand intake pipe (2) in a suitable container (not supplied) (3),
taking care to use dry sand of a quality appropriate for this pupose
(quartz or silicon sand; contact your retailer) and allowing 30 mm of
pipe to protrude from the sand.

3. Sand container (not supplied)
When starting up the high pressure cleaner, the sand (a) is aspirat-
ed, mixed with the water (b) and projected towards the surface to be
treated, freeing it from residues and incrustations.
HANDLING AND RECOVERY
Attention
Before moving the equipment it is necessary to:
• stop the machine in accordance with the indications
set out in the "STOP" paragraph;
• disconnect the electricity supply, removing the plug;
• shut off the water supply tap and unscrew the water in-
let pipe.
After coiling the electric cable and high pressure pipe on the ap-
propriate devices, take hold of the machine using the handle and make
it move on its wheels. By pressing on the handle it is possible to raise
the front wheels, thereby overcoming small obstacles; with the front
wheels raised, and by rotating the unit on its rear ones, it is possible to
orient the machine in the desired direction.
Attention
Never try to manually lift the high pressure cleaner: its
excessive weight could cause serious physical injury.
The machine must be stored in a protected location. Where it is
stored for a long period of time, it is necessary to completely empty the
water circuit (operrating the machine for a few seconds with the water
suppin off and with the spray gun on) and protect the machine from
dust. When functional once again, it is necessary to check that there
are no cracks or cuts in the hydraulic pipes.
PRECAUTIONS AGAINST FREEZING
During the winter season, the high pressure cleaner must not be
exposed to freezing, unless during normal functioning. We therefore
recommend, when operational activity has ceased, and before com-
pletely stopping the machine, closing the water supply tap and allowing
the high pressure cleaner to function until the hydraulic circuit is com-
pletely empty.
Where there are extended pauses at low temperature, we recom-
mend using an antifreeze product. After emptying the hydraulic circuit,
operate the high pressure cleaner, directly taking up the antifreeze liq-
uid through the water intake pipe and through the detergent intake pipe
until completely filling the hydraulic circuit.
Antifreeze liquid is a harmful product for the environ-
ment, and as a result it is important to follow the in-
structions set out on the product packaging.
