Connection to the mains water supply
The appliance can be connected directly to the mains
drinking water supply only if the supply hose is fitted with a
backflow preventer valve as per current regulations in force.
Make sure that the hose is at least Ø 13mm and that it is
reinforced.
ADJUSTMENT INFORMATION (Fig. C)
f Adjusting the spray nozzle: Water flow is adjusted
by regulating the nozzle (4).
f Adjusting the detergent: To deliver detergent at the
correct pressure, set the nozzle (4) (where fitted) on
" " or fit the detergent kit (9) as shown.
f Adjusting the pressur: The regulator is used
to adjust the working pressure. The pressure is shown
on the pressure gauge (where fitted).
USE OF THE APPLIANCE (Fig. D)
CONTROLS
Starter device (21)
Set the starter switch on (ON/I) to:
a) start the motor (in models without TSS device);
b) set the motor ready to start (in models with TSS
device). If there is a pilot light on the starter device, it
should light up. Set the starter device switch on
(OFF/0) to stop the appliance. If there is a pilot light
on the starter device, it should go out.
f Water jet control lever (19).
Warning! - Danger!
During operation the appliance must be positioned as
shown in Fig. D. on a firm, stable surface.
Start-up (Fig D)
1. Turn on the water supply tap fully.
2. Release the safety catch (20).
3. Depress the gun trigger for a few seconds and start up
the appliance using the starter device (ON/I).
Warning! - Danger!
Before starting up the appliance check that it is receiving water
correctly; use of the appliance without water will damage it. Do
not cover the ventilation grilles when the appliance is in use.
TSS models
- In TSS models
(with automatic delivery flow cut-off system):
f when the gun trigger is released the dynamic
pressure automatically cuts out the motor;
f when the gun trigger is depressed the automatic
drop in pressure starts the motor and the pressure is
restored after a very slight delay;
f if the TSS is to function correctly, all gun trigger
releasing and depressing operations must be at
least 4-5 seconds apart.
To prevent damage to the appliance, do not allow it to
operate dry and check that it is properly supplied with
water. For models without TSS, to prevent damage to
the appliance due to an increase in water temperature,
do not cut off the jet of water for more than 5 minutes
with the appliance running. Beware of kickback force
when opening the trigger gun.
Stopping the appliance
1. Set the starter device switch on (OFF/0).
2. Depress the gun trigger and discharge the residual
pressure inside the hoses.
3. Engage the gun safety catch (20).
Restarting
1. Release the safety catch (20).
2. Depress the gun trigger and discharge the residual
air inside the hoses.
3. Set the starter device on (ON/I).
Storage
1. Switch the appliance off (OFF/0).
2. Remove the plug from the socket.
3. Turn off the water supply tap.
4. Discharge the residual pressure from the gun until
all the water has come out of the nozzle.
5. Drain and wash out the detergent tank at the end of
the working session. To wash out the tank, use clean
water instead of the detergent.
6. Engage the gun safety catch (20).
Recommended cleaning procedure
Dissolve dirt by applying the detergent mixed with water to
the surface while still dry. When dealing with vertical surfaces
work from the bottom upwards. Leave the detergent to act for
1-2 minute but do not allow the surface to dry. Starting from
the bottom, use the high pressure jet at a minimum distance
of 30 cm. Do not allow the rinse water to run onto unwashed
surfaces. In some cases, scrubbing with brushes is needed to
remove dirt. High pressure is not always the best solution for
good cleaning results, since it may damage some surfaces.
The finest adjustable nozzle jet setting or the rotating nozzle
should not be used on delicate or painted parts, or on
pressurised components (e.g. tyres, inflation valves, etc.).
Effective cleaning depends on both the pressure and volume of
the water used, to the same degree.
MAINTENANCE (Fig. E)
Any maintenance operations not covered by this chapter should
be carried out by an Authorized Sales and Service Centre.
¡Important! To ensure product SAFETY and
RELIABILITY, repairs, maintenance and adjustment
(other than those listed in this manual) should be performed
by authorized service centers or other qualified organizations,
always using identical replacement parts. Unit contains no
user service able parts inside.
