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: En-
gine 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 clean-
er 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 rec-
ommended for liquid 2-cycle engines and performs well in all air cooled 2-cycle en-
gines. 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 fur-
ther operation of the snowmobile. Visually check the oil level in the bottle. The en-
gine can be operated as long as oil is visible in the oil tank. If oil is not visible, con-
tinued operation may cause severe engine damage.
