Break-In Period

Fuel

WARNING

Gasoline is highly flammable and explosive under certain conditions.

Always exercise extreme caution whenever handling gasoline.
Always refuel outdoors or in a well-ventilated area.
Always turn off the engine before refueling.
Do not overfill the tank. Do not fill the tank neck.
Do not smoke or allow open flames or sparks in or near the area where refueling is performed or where gasoline is stored.
If gasoline spills on your skin or clothing, immediately wash it off with soap and water and change clothing.
Never start the engine or let it run in an enclosed area. Engine exhaust fumes are poisonous and can cause loss of consciousness or death in a short time.

WARNING

The engine exhaust from this product contains chemicals known to cause cancer, birth defects or other reproductive harm. Operate this vehicle only outdoors or in well-ventilated areas.

Engine Break-In

Always follow these recommended break-in procedures for new or rebuilt engines. The first tank of fuel is considered the break-in period for the engine.

Always premix the initial fuel and future fuel.

Excessive heat build-up during the first three hours of operation will damage close-fitted engine parts. Do not operate at full throttle or high speeds for extended periods during the first three hours of use. Vary the throttle openings and vehicle speeds to reduce friction on all close-fitting machined parts, allowing them to break in slowly without damage.

Drive with extra caution during the break-in period. Perform regular checks on fluid levels, lines, and all other important areas of the machine.

Oil Recommendations

The only source of engine lubrication for this engine comes from lubrication added to the fuel. Always premix the fuel.

Never mix brands of oil. Serious chemical reactions can cause injection system blockage, resulting in serious engine damage. Oils may also be incompatible and the result could be sludge formation, filter blockage, and reduced cold weather flow rates.

Recommended Oil
600 R	VES Extreme 2–Cycle Engine Oil

Fuel Recommendations

Always use race specification fuel ONLY in this snowmobile. ALWAYS premix the fuel.

NOTICE

Using fuels with a lower than recommended octane or operating with obstructed fuel systems will result in serious and costly engine damage. Always use the recommended fuels for your machine.

NOTICE

Prolonged exposure to petroleum based products may damage paint. Always protect painted surfaces when handling fuel.

Fuel Premix

Initial Tank of Fuel
Fuel	Oil	Ratio
3.5 gal (13.2 L)	16 oz (473 mL)	28:1

Future Fuel
Fuel	Oil	Ratio
3.5 gal (13.2 L)	14 oz (414 mL)	32:1

Fuel System Deicers

If you use non-ethanol fuel (sometimes labeled “non-oxygenated”), POLARIS recommends the regular use of isopropyl-based fuel system deicer. Add 1-2 ounces per gallon (8-16 ml per liter) of gasoline to prevent damage resulting from fuel system icing. Never use deicers or additives containing methanol. POLARIS recommends the use of Carbon Clean.

IMPORTANT

If you use fuel with up to 10% ethanol (sometimes labeled “oxygenated”) do not add deicers or additives that contain any form of alcohol. Adding deicer to oxygenated fuels could result in severe engine damage.

Drive Belt Break-In

The break-in period for a new drive belt is 30 miles (48 km). During this time, vary the throttle position under 50% and limit full throttle use.
New drive belts should be washed with warm, soapy water and allowed to air dry prior to use.
Always take time to warm up the belt and driveline prior to operating the snowmobile. Free the track and skis from the ground before engaging throttle.
