4.5 Safety devices

Caution - Danger!

Do not tamper with or adjust the safety valve setting.

Safety valve and/or pressure limiting valve.

The safety valve is also a pressure limiting valve.

When the gun trigger is released, the valve opens and the water recirculates through the pump inlet.

- Safety catch (D): prevents accidental spraying of water.

5 INSTALLATION (FIG.2)

5.1 Assembly

Caution - Danger!

All installation and assembly operations must be formed with the appliance disconnected from the mains supply.

The assembly sequence is illustrated in fig.2.

5.2 Assembling the rotating nozzle

(For models with this feature)

The rotating nozzle kit delivers greater washing power.

Use of the rotating nozzle may cause of reduction in pressure of 25% compared to the pressure obtained with the adjustable nozzle. However, the rotating nozzle kit delivers greater washing power due to the rotation of the water jet.

5.3 Electrical connection

Caution - Danger!

Check that the electrical supply voltage and frequen-Hz) correspond to those specified on the appliance plate (fig.2). The appliance should only be connected mains power supply equipped with an adequate earth section and a differential security breaker (30 mA) to cut the electricity supply in the instance of a short circuit.

5.3.1 Use of extension cables

Use cables and plugs featuring "IPX5" protection level.

The cross-section of the extension cable should be proportionate to its length; the longer it is, the greater its cross-section should be. See table I.

5.4 Water supply connection

Caution - Danger!

Only clean or filtered water should be used for intake.

The delivery of the water intake tap should be equal to that of pump capacity.

Place the appliance as close to the water supply system as possible.

5.4.1 Connection points

● Water outlet (OUTLET)

■ Water inlet with filter (INLET)

5.4.2 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 13 mm and that it is reinforced.

6 ADJUSTMENT INFORMATION (FIG.3)

6.1 Adjusting the spray nozzle (for models with this feature) Water flow is adjusted by regulating the nozzle (E).
6.2 Adjusting the detergent (on models with this feature) Detergent flow is adjusted using the regulator (F).

6.3 Adjusting the detergent pressure

Set the adjustable nozzle (E) on "—" to deliver detergent at the correct pressure (on models with this feature).

6.4 Adjusting the pressure (on models with this feature)

The regulator (G) is used to adjust the working pressure. The pressure is shown on the pressure gauge (where fitted).

7 INFORMATION ON USE OF THE APPLIANCE (FIG.4)

7.1 Controls

- Starter device (H).

Set the starter switch on (ON/1) to set the motor ready to start.

Set the starter device switch on (OFF/0) to shut down the appliance.

- Water jet control lever (I).

Caution - Danger!

During operation the appliance must be positioned down in fig. 4 on a sturdy, stable surface.

7.2 Start-up

1) Turn on the water supply tap fully.

2) Release the safety catch (D).
3) Depress the gun trigger for a few seconds and start up the appliance using the starter device (ON/1).

Caution - Danger!

Before starting up the appliance check that the water supply hose is connected properly; 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:

• when the gun trigger is released the dynamic pressure automatically cuts out the motor (see fig.4);
• when the gun trigger is depressed the automatic drop in pressure starts the motor and the pressure is restored after a very slight delay;
• if the TSS is to function correctly all gun releasing and depressing operations must be performed at intervals of less than 4-5 seconds.

To prevent damage to the appliance, do not allow it to operate dry.

7.3 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 (D).

7.4 Restarting

1) Release the safety catch (D).
2) Depress the gun trigger and discharge the residual air inside the hoses.
3) Set the starter device on (ON/1).

7.5 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 (D).

7.6 Refilling and using detergent

When using detergent, the adjustable nozzle must be set on

" (on models with this feature).

Use of a high pressure hose longer than the one originally supplied with the cleaner, or the use of an additional hose extension, may reduce or completely halt the intake of detergent.

Fill the tank with highly degradable detergent.

7.7 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 minutes 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 washing 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 washing depends on both the pressure and volume of the water used, to the same degree.

8 MAINTENANCE (FIG.5)

Any maintenance operations not covered by this chapter should be carried out by an Authorized Sales and Service Centre.

Caution - Danger!

Always disconnect the plug from the power socket to be carrying out any work on the appliance.

8.1 Cleaning the nozzle

1) Disconnect the lance from the nozzle.
2) Remove any dirt deposits from the nozzle hole using the tool (C1).

8.2 Cleaning the filter

Inspect the intake filter (L) and detergent filter (if fitted) before each use, and clean in accordance with the instructions if necessary.

8.3 Unjamming the motor (on models with this feature)

In case of lengthy stoppages, limescale sediments may cause the motor to seize. To unjam the motor, turn the drive shaft with a tool (M).

8.4 End-of-season storage

Treat the appliance with non-corrosive, non-toxic antifreeze before storing it away for winter.

Put the appliance in a dry place, protected from frost.
