low and high pressure. The pressure selection is car-
ried out by rotating the adjusting head. To increase
the pressure, rotate the adjusting head clockwise,
to reduce the pressure rotate it anti-clockwise. The
detergent suction is automatic when the adjusting
head of the lance is rotate for low pressure operation
(anti-clockwise).
• 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

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 oil is recommended . 0,5 Kg.
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 perio-
dically with specific products. The interval depends
on the hardness of the water. Pour one litre of pro-
duct for every 15 litres of water into a drum contai-
ning 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 circuit, 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 returned 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 descaling product may cause wear
of components. Comply with the regulations in for-
20
ce 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.
Fault When switch "ON" the machine will
not start working
Cause • Plug not properly inserted in socket.
• Electric socket is faulty.
• The main voltage is insufficient.
• The pump is stuck.
• Gauge of extension lead not sufficient.
Repair • Fit plug in power socket correctly.
• Have electrical socket checked.
• Have a check made on the suitability of
the mains system.
• Turn switch to ON while keeping nozzle
trigger pressed; if problem persists, con-
tact an authorised service centre.
Fault The motor stops suddenly
Cause • Thermic safety switch has tripped due to
the overheating.
• Cable extension seems to be inade-
quate.
Repair • Leave motor to cool for a few minutes. If
the problem persists, contact an author-
ised service centre..
Fault The pump doesn't reach the neces-
sary pressure
