Caution - Danger! Do not tamper with or adjust the safety valve set- ting.- Safety valve and 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.

Caution - Danger! All installation and assembly operations must be performed with the appliance disconnected from the mains power supply.The assembly sequence is illustrated in fig.2.

3.2 Assembling the rotating nozzle

(For models with this feature)The rotating nozzle kit delivers greater washing power.

3.3 Electrical connection

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

3.3.1 Use of extension cables

Use cables featuring “IPX5” protection level.The cross-section of the extension cable should be pro- portionate to its length; the longer it is, the greater its cross-section should be. See table I.

3.4 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.

3.4.1 Connection points

Water outlet (OUTLET) Water inlet with filter (INLET)

3.4.2 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 Ø 13 mm and that it is reinforced.11English

ADJUSTMENT INFORMATION FIG.3

4.1 Adjusting the spray nozzle (for models with this feature)

Water flow is adjusted by regulating the nozzle (E).

4.2 Adjusting the detergent (on models with this feature)

Detergent flow is adjusted using the regulator (F).

4.3 Adjusting the detergent pressure

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

4.4 Adjusting the pressure (on models with this feature)

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

- Starter device (H).Set the starter switch on (ON/1) 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.If the “low/high” settings are available, use them as follows:Low : low pressure washingHigh : high pressure washingSet the starter device switch on (OFF/0) to shut down the applian- ce. If there is a pilot light on the starter device, it should go out. - Water jet control lever (I). Caution - Danger! During operation the appliance must be positioned as shown in fig. 4 on a sturdy, stable surface.

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.On three-phase models for professional use, at first use start the appliance for a very short time to check that the motor is running in the correct direction. If the motor fan is turning anti-clockwise, exchange two of the three phase wires (L1, L2, L3) in the electrical plug.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 appli ance using the starter device (ON/1). TSS models - In TSS models with automatic delivery flow cut-off system:- when the gun trigger is released the dynamic pressure automati-cally cuts out the motor (see fig.4);- when the gun trigger is depressed the automatic drop in pres- sure starts the motor and the pressure is restored after a very slight delay;- if the TSS is to function correctly all gun releasing and depress-ing operations must be performed at intervals of less than 4-5 seconds.To prevent damage to the appliance, when running do not stop the water jet for more than 10 minutes at a time.

5.3 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).

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).

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 the detergent tank.6) Engage the gun safety catch (D).

5.6 Refilling and using detergent

When using detergent, the adjustable nozzle must be set on " " (on models with this feature).Fill the tank with highly degradable detergent.

5.7 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.

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 before carrying out any work on the appliance.

6.1 Cleaning the nozzle

1) Disconnect the lance from the nozzle.

2) Remove any dirt deposits from the nozzle hole using the tool

6.2 Cleaning the filter

Clean the suction filter (L) and the detergent filter after every 50 hours of operation.

6.3 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).

6.4 End-of-season storage

Treat the appliance with non-corrosive, non-toxic antifreeze before storing it away for winter.12 English
