[. . . ] This high pressure washer/cleaner is only allowed to be connected with the drinking watermains, when an appropriate backflow preventer has been installed, Type BA according to EN 1717. If the back flow preventer hasn't been supplied, one can be ordered from your dealer. The length of the hose between the backflow preventer and the high pressure washer must be at least 6 metres (min diameter 3/4 inch) to absorb possible pressure peaks. Operation by suction (for example from a rainwater vessel) is carried out without backflow preventer. [. . . ] Draw in the antifreeze from the container by activating the spray handle. Having placed the spray handle above the antifreeze funnel, open and close it a few times, so that the antifreeze can circulate. Activate the spray handle and allow the rest of the antifreeze to run back into the container. The antifreeze will be diluted with water and will after some time lose its effect. IMPORTANT: To avoid damage always ensure that the cleaner, the hoses and the spray lance are unfrozen before restarting. Place the cleaner and the accessories in a warm place for some time before starting up. Screw in the plug and refill the pump with fresh oil through the oil glass. From Nilfisk-ALTO the pump is filled with zincless hydraulic oil - Nilfisk-ALTO Pump Oil 100. When refilling and changing the oil this or an oil with the following specifications should be used: ISO no. 130 Pour point below -30°C Concerning oil for mist lubricating, see section. Your Nilfisk-ALTO cold water cleaner is designed and manufactured to comply with the very latest labour regulations. Always hold the spray handle and lance firmly in both hands during operation at high pressure. Never direct the high pressure spray towards people or electrical devices. The filter can be removed, when the quick coupling has been unscrewed. To avoid leakages and damage to the quick couplings on hoses, spray handle and spray lance it is necessary to clean and lubricate the parts regularly with a little oil or grease. Do not disconnect the high pressure hose until the cleaner has cooled down and stopped. Never tie knots in or kink the high pressure hose as it may be damaged and consequently burst. However if cleaner, hose or lance should become frozen do not use until they have thawed. The high pressure pump features a safety valve, the adjustment of which SHOULD NOT BE CHANGED. The machine should only be used by people who have been properly instructed. The vanes take up their own wear and will last 5, 000-15, 000 hours depending upon speed, method of oiling, operating pressure, and the precautions taken in maintaining the motor. The type of shaft seal used does not lend itself to operating pressures above 100 Psi (6. [. . . ] Excessive moisture in the air line can cause rust formation in motor and might also cause ice to form in the muffler due to expansion of air through the motor. The moisture problem can be corrected by installing a moisture separator in the air line and also by installing an aftercooler between the compressor and air receiver. The starting torque is less than the running torque and could vary depending on the position at which the vanes stop in relation to the air intake port. The Nilfisk-ALTO 03K-series of cold water cleaners is produced in several models. [. . . ]
