HIGH PRESSURE WASHER
> START-UP
(
fig. )
• Whenever using the high-pressure cleaner, users are
urged to hold the gun in the correct position, with one
hand on the grip and the other on the spray rod.
• To start the machine, press the gun trigger
and at the same time turn the master switch to
“ON”
> APPLIANCES PROVIDED WITH THER-
MAL VALVE (OPTIONAL)
This device enables the machine’s by-pass op-
eration through automatic water discharge
whenever it reaches a temperature of nearly
60°C and cooling working components.
WARNING:
appliances that are not provided with
this disposal must not operate for more than 2 minutes
with released gun. Recycled water raises its temperature
remarkably causing great damages to the pump.
> DETERGENT SUCTION
(see fig.
NOZZLE at low pressure
(if included)
(see fig. )
Insert the CHEMICAL nozzle into the lance. Plunge
suction hose with filter into detergent tank. When
you start the machine, the mixing of the detergent
with the water is automatic at the water passage.
CAUTION: Make use only of liquid detergent, do not
absolutely use acid or too much alkaline products.
We suggest you to make use of our products, which
have been studied for the use with washer machines.
CARE AND MAINTENANCE
(vedi fig. )
IMPORTANT: Before doing any work
on the cleaner, discharge the pressure
and disconnect the electricity and water
supplies.
CHECKING THE PUMP OIL LEVEL
Check the oil level periodically. The oil must be
changed for the first time after 50 working hours,
with subsequent changes every 500 hours. SAE
20/30 , 15W-40, 20W-40 (600 gr) oil is recommended
.
CHECKING THE WATER INTAKE FILTER
Inspect and clean the water intake filter on the inta-
ke union periodically. This is important to prevent
fouling which may impair operation of the pump.
CHECKING THE SPRAY ROD NOZZLE
Replace the nozzle when the pressure drops
below the normal values.
DESCALING
The descaling procedure must be carried out periodically
with specific products. The interval depends on the hard-
ness of the water. Pour one litre of product for every 15
litres of water into a drum containing at least 30 litres of
water. Disconnect the gun from the high pressure line and
place its free end in the drum, in order to form a closed cir-
cuit, and draw the solution into the machine for at least 10
minutes. The delivery end of the line should discharge into
a canvas or mesh bag so that the scale removed is not re-
turned to the circuit. Then restore the normal connection
and rinse with plenty of cold water. This operation should
be carried out by our after-sales service, since the descal-
ing product may cause wear of components. Comply with
the regulations in force when disposing of the descaling
agent.

TROUBLESHOOTING
Before doing any work on the machine, disconnect
the electricity and water supplies and discharge the
pressure. Proceed systematically to identify Faults
following the chart below; if you are still unable to
eliminate the problem, call in the Authorized After-
Sales Service .
