the jet is even; otherwise, clean the nozzle to
remove any dirt. Wait a few seconds for the op-
erating pressure to be reached, then operate
the gun for two or three short bursts.
> LANCE ASSEMBLY
(pict. 10A-10B)
To fit the lance to the gun, it is sufficient to in-
sert the threaded end of the lance into the hole
on the gun ; then screw the lance as shown by
the arrow (A) until the connection is tight.
> DETERGENT SUCTION
Fill up the detergent tank with the suggested
products, suitable for the kind of washing to be
carried out (pict. 1, pos. 8).
•
CAUTION: Make use only of liquid de-
tergent, 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.
•
CAUTION: For proper use of the tank, do
not introduce flammable or chemically
harsh substances.
The adjusting head allow you to select water
jet at low and high pressure. Pressure can be
adjusted by acting on nozzle knob (pict. 17):
pict. "B" means low pressure, "A" means high
pressure. The selection of low or high pressure
shall be carried out with gun in closed posi-
tion. The detergent suction is automatic when
the adjusting head of the lance is positioned
for low pressure operation. When you start the
machine, the mixing of the detergent with the
water is automatic at the water passage.
> APPLIANCES PROVIDED WITH THERMAL
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.
•
CAUTION: appliances that are not pro-
vided with this disposal must not oper-
ate for more than 2 minutes with released
gun. Recycled water raises its temperature
remarkably causing great damages to the
pump.
> GUN SAFETY DEVICE
Whenever the machine has to be stopped, it is
important to engage the safety catch (pict. 14,
pos. S) on the gun so that it cannot be operated
accidentally.

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 - Oil ca-
pacity 0,5 Kg
CHECKING THE WATER INTAKE FILTER
Inspect and clean the water intake filter (pict.21)
on the intake union periodically. This is impor-
tant to prevent fouling which may impair op-
eration of the pump.
REPLACING THE SPRAY ROD NOZZLE
Replace the nozzle when the pressure drops
below the normal values.
ELECTRIC MOTOR
If the motor malfunctions, it cuts out. Wait 5-10
minutes before restarting. If the problem per-
sists, refer to the "TROUBLESHOOTING" section.
If you are still unable to eliminate the problem,
stop using the machine and contact an Author-
ized Service Centre.
