[. . . ] Ensure that any exhaust emissions are not in a vicinity of air intakes. Because of exhaust emissions, airborne dust and aerosols, use proper safety gear when necessary. It can be used for cleaning agricultural and construction equipment, stables, vehicles, rusty surfaces, etc. The cleaner has not been approved for cleaning surfaces which comes into contact with food. [. . . ] Extension cables should be of a watertight construction and comply with the below-mentioned requirements for length and cable dimensions. 1 Operation Before starting up the cleaner each time, please check it carefully for any defects. Also check the high pressure hose and gun, the insulation of the electric cable should be faultless and without any cracks. NOTE To achieve a long life and avoid problems with dirt in the gun and lance, the coupling and nipple have to be kept clean. Insert the nipple of the spray lance (B) into the quick-release connection and release it. Pull the spray lance (or other accessory) forwards to check that it is securely attached to the spray gun. NOTE Always remove any dirt from the nipple before connecting the spray lance to the spray gun. EN NOTE The cleaner switches off automatically twenty seconds after the spray gun has been closed. Safety control block all the way to the left (counterclockwise-direction). For special applications: replace the standard nozzle with the steam spray nozzle (accessory). High pressure = clockwise (+) for high pressure · Low pressure = counterclockwise (­) for low pressure. Turn off the cleaning agent and spray until clean water is comming out of the lance. For special applications such as disinfection, the exact detergent concentration has to be determined by using a graduated measuring container. The use of cleaning agents while using the steam device will show a lower percentage and will result in a lower concentration. This machine shall only be used with cleaning chemicals supplied or recommended by Nilfisk ALTO. This machine will, when a cleaning agent has been chosen, spray out the detergent on high- as well as low-pressure. To lenghten the lifetime of the machine, make sure to flush the system with clean water after using chamicals. 1 Techniques Efficient high pressure cleaning is achieved by following a few guidelines, combined with your own personal experience of specific cleaning tasks. Accessories and detergents, when correctly chosen, can increase the efficiency of your pressure washer. Encrusted or thick layers of dirt can be loosened or softened up by a period of soaking. This is for example an ideal method within agriculture ­ for example, within pig sties. The ideal soaking method can be achieved by using foam or simple alkaline detergent.
