High Pressure Washer 380V 7.5kW

A 7.5kW high-pressure washer.Specifications:Power: 7.5kWVoltage: 380V Three phaseRevolutions: 1450RPMMax. Pressure: 240 barFlow: 20.7 L/minUsage:The machine must be switched off when not in use. If the gun is released and the pump enters its unloading state, the machine can only facilitate this for 30 seconds before the water starts overheating and ultimately damaging the pump. If any damage comes to the pump from deformation or destruction of internal components, overheating is the likely cause.The machine comes with a Red Gun, a 7m 280bar high-pressure hose, a short hose, a low-pressure chemical injector, and the following nozzles:Red nozzleYellow nozzleWhite nozzleBlack nozzleSCRUBIO Cleaning Equipment stocks the parts and spares of this machine and has repair facilities for the machine.WARNING"MUST DO"All electrical conductors MUST BE PROTECTED against the water jet.The appliance MUST ONLY BE CONNECTED to a correct earthed power supply.TIP: Use of Safety Residual Current Circuit-breaker(r.c.c.b) will provide additional protection for the operator(30mA).The high pressure jet may cause loose particles to be propelled at high speed, therefor protective clothing and safety glasses MUST BE WORN.Before carrying out any work on the cleaner, DISCONNECT the plug from the electrical supply socket.Before pressing the trigger, GRIP the gun firmly to counteract the recoil.Maintenance and repair of electrical components MUST be done by a qualified staff.DISCHARGE residual pressure before disconnecting the high pressure hose.Before using the appliance, CHECK every time that the screws are fully tightened and that there are no broken or worn parts.Only use detergents which will not corrode the coating materials of the machine and it's parts. DO NOT USE bleach, alcohol, petrol, hydrochloric acid etc. as the solvents that are flammable and erodable.The appliance operates at fluid pressures and velocities high enough to penetrate human and animal flesh, which could result is amputation or serious injury. DO NOT TREAT FLUID INJECTIONS AS A SAMPLE CUT! SEE DOCTOR IMMEDIATELY!Only use chemicals desighed for pressure washer using mild soaps and chemicals compatible with aluminium and brass parts of the pressure washer.The machine uses normal temperature and the temperature for the inlet should not be used with the temperature of 0°C or under 0°C. "MUST NOT DO"Do not use the appliance with inflammable or toxic liquid, or any products which are not compatible with the correct operation of the cleaner.Do not use the appliance within range of persons unless protective clothing are worn.Do not use the appliance if supply cord or important parts of the appliance are damaged, e.g. safety devices, high pressure hoses, trigger gun.Do not direct the water jet towards people, animals, electrical equipment or the machine itself.Do not use the appliance outdoors in case of rain.Do not allow children or unprofessional staff to use the machine.Do not though the plug or socket with wet hands.Do not use the appliance if electrical cord is damaged.Do not use the appliance if the high pressure hose is damaged.Do not jam the trigger in the operating position.Do not with or alter the calibration of the safety valve.Do not alter the original diameter of the spray nozzle.Do not leave the appliance unattended.Do not move the appliance by pulling the electrical cord.PUMP OPERATING FEATURESPlease check each part according to the packing list when opening the carton, to check whether the parts are complete and in good condition. Keep all documents and manuals. CHANGE OIL INLET PLUGThe red plug on the pump is specially designed for transportation, before using the unit, please replace the red plug with the yellow plug or the brass plug in the spare parts package.PRESSURE REGULATORThe pressure setting is preset at the factory to achieve optimum pressure and cleaning. If need to lower the pressure, the following methods can be used: Back away from the surface to be cleaned. The further away the user is, the less pressure is on the surface to be cleaned.DO NOT try to increase pump pressure, a higher pressure setting may damage the pump.Change to the 40° white nozzle. This nozzle delivers a less powerful stream of water and a wider spray pattern. Adjust the pressure regulator on the pump. Turn the pressure regulator knob anti-clockwise to lower the pressure. Once you have finished using your pressure washer, return the pressure regulator to it's original position by turning it clockwise. DO NOT try to turn pressure regulator knob past the build-in stop line otherwise damage to the pump may be resulted. TYPE OF NOZZLE Your unit is equipped with four spray nozzles. Each nozzle is colour coded, and delivers a specific spray pattern for a particular cleaning purpose.Red: 0° nozzle Yellow: 15° nozzle White: 40° nozzle Black: Chemical nozzleCAUTIONThis high pressure spray from your unit is capable of causing damage to surfaces suck as wood, glass, automobile paint, auto striping and trim, and delicate objects such as flowers and shrubs. Before spraying, check the item to be cleaned to assure yourself that it is strong enough to resist damage from the force of the spray.CHANGING NOZZLES DO NOT attempt to change the nozzle while the unit is running. Turn the engine or gun OFF before changing the nozzle.Pull quick-release back and insert nozzle.Release quick-release and twist nozzle to make sure it is secure in quick-release socket.Risk of injury. Ensure nozzle is completely inserted in quick-release socket before turning on gun trigger.CONNECTION TO ELECTRICAL SUPPLYMake sure that the mains voltage is the same as shown on the identification label on the identification label on the machine.WARNING Make sure that the plug complies with your local regulations, and it is provided with ground connection (earth)WARNING The power outlet must be protected by a residual circuit breaker with a sensitivity of less than 30mA.WARNING Do not connect other appliances to the same outlet.WARNING Insert the plug after checking the switch joint the machine in the OFF position.STARTING THE MACHINEWARNING In case of power failure, turn the unit OFF for safety reasons.Supply water to the machine, then press the gun triggerSwitch on the unit.Hold the gun in the open position for a few seconds to drain the air from the hose.At this stage, adjust the machine pressure to your pressure requirement and you are ready to enjoy your work.During washing, it is better not to exceed the recommended pressure.During washing, the spray head should not be far away from the dirty surface.WARNING Do not use the machine when people or animals are in range of the jet.Stop the gun after ending the washing, then switch the engine off. Do not let the unit run with the gun switched off for more than 2 minutes. The unloading valve is still moving agter stopping the gun, the water will flow in circle in the pump, which will make the water hot and damage the seal ring, ceramics or other accessories if the machine is kept running.During the operation, it is normal if there is a little water leaks out from the pump, which will not effect the use of the machine.SAFETY VALVE: The safety valve also functions as a pressure limiting valve. When the gun trigger is released, the safety valve opens and the water recirculate through the pump inlet.STOPPING THE MACHINEWhen not in use, switch the machine off. Hold the gun in the open position for a few seconds to drain water from the hose. WARNINGHigh pressure water jets are potentially dangerous is used incorrectly. In particular, DO NOT direct the water jet towards people or animals, electrical equipment or the unit itself.APPLICATION FIELDTo maintain and wash the deversified vehicles, project machinery, architecture and agricultural machinery.To maintain and wash the army vehicles, tanks, naval vesssels, planes, and other military machinery.Wash and disinfect the diver sited harbour containers.Wash sanitation recovery and disinfection at stock farm, breeding house and slaughterhouse. Daily wash of buildings glass and the outside walls.Wash and disinfect the enviroment of townsfolk square, carnie, hospitals, hotels, restaurants and the courtyard.PUMP OPERATING FEATURESThe level of the oil must be checked periodically.It is most important that the oil is changed after the first 50 hours of work and successively every 100 hous.In any case we suggest to change the oil at least once a year.OIL TYPE: SAE 15W-40 or equivalent motor oil.How to change pump oil:Drain the old pump il completely through the oil outlet plug.Install the oil outlet plug again and pour the clean oil in the crankcase, the oil level should be slightly over the center line of the oil mirror.
