The operator must meet specific physical and mental requirements to be suitable for the job in hand; the cleaner must therefore only be used by the appointed person. 2.3 Improper use Use by unskilled persons or those who have not read and understood the instructions in the manual is forbidden. The introduction of inflammable, explosive and toxic liquids into the cleaner is prohibited. Use of the cleaner in a potentially inflammable or explosive atmosphere is forbidden. The use of non-original accessories and any other accessories not specifically intended for the model in question is prohibited. All modifications to the cleaner are prohibited. Any modifications made to the appliance shall render the Declaration of Conformity null and void and relieve the manufacturer of all liability under civil and criminal law. 2.4 Main components B1 -Engine B2 -Reduction gearbox (where fitted) B3 -Pump B4 -Gun with safety catch B5 -Lance B6 -High pressure hose B7 -Oil caps 2.4.1 Accessories C1 Nozzle cleaning tool C2 Rotopower (where fitted) 2.5 Technical data The technical data are specified in the enclosure. 2.6 Safety devices Caution -Danger! Never tamper with the safety devices. -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. -Thermostat valve (D1) If the water temperature exceeds the temperature set by the manufacturer, the thermostat valve discharges the hot water and draws in an amount of cold water equal to the amount of water discharged. -Safety catch (D): prevents accidental spraying of water. 2.7 Noise levels At even short exposure times, noise may cause hearing impairment in the long term. Users must wear ear defenders to protect their hearing. 3 INSTALLATION (FIG. 2) 3.1. Assembly Caution -Danger! All installation and assembly operations must be performed with the engine off. The assembly sequence is illustrated in fig. 2. 3.2 Fitting the pressure release caps To prevent oil leaks, the appliance is delivered with the oil intakes sealed with red caps which must be replaced with the pressure release caps supplied. 3.3 Assembling the rotating nozzle (where fitted) The rotating nozzle kit delivers greater washing power. 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. Do not use container and tanks to supply the appli ance. Place the cleaner as close to the water supply system as possible. 3.4.1 Connection points l Water outlet (OUTLET) n Water inlet with filter (INLET) 3.4.2 Connection 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 O 13 mm and that it is reinforced. 4 ADJUSTMENTS (FIG. 3) 4.1 Adjusting the pressure The regulator (G) is used to adjust the working pressure. The pressure is shown on the pressure gauge. 4.2 Adjusting the nozzle Water flow is adjusted by regulating the nozzle (E). 5 INFORMATION 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. 5.1 Preliminary 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 characteristics (see the “Oil characteristics” table). 5.2 Controls 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. 5.3 Starting 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. 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. 5.4 Stopping 1) Stop the engine. 2) Depress the gun trigger and discharge the residual pressure inside the hoses. 3) Engage the gun safety catch (D). 5.5 Refilling and using detergent IPlace the hose straight in the detergent container. 5.6 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 ...
