M. ) AND HIGH PERFORMANCE SYNTHETIC OIL FOR 2 STROKE ENGINES. THE USE OF FUELS AND LUBRICANTS DIFFERENT FROM THOSE INDICATED CAUSES SEVERE FUNCTIONAL INCONVENIENCES TO THE VEHICLE AND THE VOIDING OF THE aprilia GUARANTEE. To have the catalytic converter functioning correctly for long periods and to reduce possible problems regarding the contamination of the thermal unit and of the exhaust, it is necessary to avoid covering long distances with the engine running at constantly low rpm. It is sufficient to alternate these periods with periods in which the engine runs at relatively high rpm, even if only for a few seconds, but rather frequently. [. . . ] Wait for it to cool down, then check the level of the coolant (see "COOLANT CHECKING") and top up if necessary. If the level not is normal have the cooling system checked by an aprilia Official Dealer. The vehicle is equipped with a side stand with automatic return. To prevent damages to the person and to the vehicle, put the vehicle on its stand only after having switched off the engine and having got off from the vehicle l. h. Open the side stand making sure it has run its entire stroke; only then you may charge it with the vehicle load. It is absolutely forbidden to put the vehicle on the stand while being seated on it. MAINTENANCE See "PERIODIC MAINTENANCE CHART". Before beginning any maintenance operation or any inspection of the vehicle, stop the engine, extract the key, wait until the engine and the exhaust system have cooled down and if possible lift up the vehicle by means of the proper equipment, on firm and flat ground. Keep away from the red-hot parts of the engine and of the exhaust system, in order to avoid burns. Do not hold any mechanical piece or other parts of the vehicle with your mouth: the components are not edible and some of them are noxious or even toxic. If not expressly indicated otherwise, for the reassembly of the units repeat the disassembly operations in reverse order. Usually ordinary maintenance operations can be carried out by the user, but sometimes a basic knowledge of mechanics and specific tools are required. If you need assistance or technical advice consult your aprilia Official Dealer, who can ensure you quick and careful servicing. 41 REGULAR SERVICE INTERVALS CHART OPERATIONS TO BE CARRIED OUT BY THE aprilia Official Dealer (WHICH CAN BE CARRIED OUT EVEN BY THE USER).
