OPERATION Lubrication The fuel and oil which enter the engine through the fuel and oil injection systems provide the only source of engine lubrication, and must be of the highest quality. You can understand the importance of proper lubrication when you realize that at 6000 RPM the crankshaft is rotating 100 revolutions per second. Premium 2-Cycle Lubricant The only oil recommended for this fuel system is Polaris brand oil. CAUTION: Engine warranty coverage may become void if other brands are substituted. Polaris Premium Gold Synthetic Lubricant is the most advanced formulation of oil available for today's 2-cycle engines. Over twenty months of lab and field tests have resulted in a new generation of 2-cycle lubricant. Polaris Premium 2-Cycle Lubricant addresses the problem of lower quality fuel; keeping ring grooves cleaner with less ring sticking and providing improved overall engine cleanliness. With new generation lubricity technology, it excels in meeting the lubricity demands of today's faster, more precisely engineered 2-cycle engines. It is the optimum oil recommended for liquid 2-cycle engines and performs well in all air cooled 2-cycle engines. We believe this oil is the best product available in the market today, and strongly recommend its use in all of our products. Never mix other brands of oil since they may be incompatible, resulting in sludge formation, filter blockage and reduced cold weather flow rates. Oil Injection System The fuel-to-oil mix ratios are controlled by the oil pump and the movement of the oil pump arm. The fuel-to-oil mix ratio corresponds to the engine's RPM and throttle valve opening. Always fill the oil reservoir when refueling. NOTE: Mix two pints of Polaris injection oil to the first tankful of gasoline. In addition to the lubrication supplied by the injection system, this will ensure proper engine break-in. CAUTION: Check the oil tank level often during the first tankful of fuel. If the oil level doesn't go down, contact your dealer immediately. Continue using premixed fuel until the oil injection system can be inspected. Low Oil Indicator Light The low oil indicator light is standard on most models. CAUTION: When the low oil indicator light is on, it indicates that oil must be added before further operation of the snowmobile. Visually check the oil level in the bottle. The engine can be operated as long as oil is visible in the oil tank. If oil is not visible, continued operation may cause severe engine damage. 32
