3.3Assembling the rotating nozzle (where fitted) The rotating nozzle kit delivers greater washing power.
3.4Water 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.
Do not use container and tanks to supply the appli- ance.
Place the cleaner as close to the water supply system as possible.
3.4.1Connection points
• Water outlet (OUTLET)
n Water inlet with filter (INLET)
3.4.2Connection to the mains water supply
The cleaner 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.
4ADJUSTMENTS (fig. 3)
4.1Adjusting the pressure
The regulator (G) is used to adjust the working pressure. The pressure is shown on the pressure gauge.
4.2Adjusting the nozzle
Water flow is adjusted by regulating the nozzle (E).
5INFORMATION FOR USE (fig. 4)
Caution - Danger!
Never use the cleaner when malfunctioning.
In the event of damage, the high pressure hose must be replaced immediately to prevent bursts.
5.1Preliminary checks
Before using the cleaner, check the oil level:
-in the engine (see engine constructor’s manual);
-in the reduction gearbox (where fitted);
-in the pump.
Check the reduction gearbox and pump oil gauges to check the oil level. It should be halfway up the gauge. If necessary, top up with oil having the same characteris-
tics (see the “Oil characteristics” table).
5.2Controls
For information about the engine controls, refer to the engine constructor’s manual.
- Water jet control lever (I).
Caution - Danger!
During operation the cleaner must be positioned on a flat surface firm enough to support it securely.
5.3Starting the appliance
Caution - Danger!
Before starting up the cleaner check that the water supply hose is connected properly; use of the cleaner without water will damage the appliance.
1)Turn the water supply tap fully on.
2)Release the safety catch (D).
English 11
3)Keep the gun trigger depressed and start the engine.
4)Keep the gun trigger depressed for a few seconds to vent the air from the pump.
To prevent damage to the appliance, when running do not stop the water jet for more than 5 minutes at a time.
5.4Stopping
1)Stop the engine.
2)Depress the gun trigger and discharge the residual pressure inside the hoses.
3)Engage the gun safety catch (D).
5.5Refilling and using detergent
IPlace the hose straight in the detergent container.
5.6Recommended 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 bot- tom upwards.
Leave the detergent to act for
5.7Ending the working session
1)Stop the engine.
2)Turn off the water supply tap.
3)Discharge the residual pressure from the gun until all the water has come out of the nozzle.
4)Engage the gun safety catch (D).
5)Remove the water intake hose.
6)Remove the detergent hose from the container.
6MAINTENANCE (fig. 5)
Any maintenance operations not covered by this chapter should be carried out by an Authorised Sales and Service Centre.
Caution - Danger!
Stop the engine before doing any work on the cleaner.
6.1Cleaning the filter
Clean the suction filter (L) after every 50 hours of operation.
6.2Topping up the oil level
The oil level must be topped up with the cleaner on a flat surface.
Remove the casing (where fitted) to top up the oil level. Replace the casing (where fitted) when done.
6.2.1Topping up the pump oil
Add oil through the intake hole to restore the correct level.
For oil characteristics, refer to the “Oil characteris- tics” table.
6.2.2Topping up the reduction gearbox oil (where fitted) Add oil through the intake hole to restore the correct level.
For oil characteristics, refer to the “Oil characteris- tics” table.
