AXYS FUEL SYSTEM MAINTENANCE
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.
AXYS snowmobiles do not feature in-line fuel filters. The
fuel pump uses a sock-type pickup filter located within
the fuel tank. This filter should only require maintenance
if debris or foreign material enters the fuel tank. See Fuel
System chapter for more information.
Contaminated or poor quality fuel may shorten the life of
fuel system components and result in poor engine
performance. Always store fuel in clean fuel containers.
Inspect the fuel lines regularly for signs of deterioration
or damage. Always check fuel line condition after periods
of storage. Normal deterioration from weather and fuel
compounds may occur. Replace worn or damaged fuel
lines promptly.
IMPORTANT
Kinking the fuel lines or using a pliers or similar tools to
remove fuel lines may cause damage to the lines. If a
fuel line has been damaged or kinked, replace it
promptly.
Fuel Recommendation
For peak performance, POLARIS recommends the use
of 91 octane fuel or higher. Although 87 octane fuel is
usable, some engine performance will be lost and fuel
economy will decrease. Do not use lower than 87 octane
fuel. Do not use fuel containing more than 10% ethanol.
Never use E85 fuel in your snowmobile.
IMPORTANT
Operating with obstructed fuel systems will result in
serious engine damage. Perform maintenance as
recommended.
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 one to two
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.
INTAKE FILTERS
The intake foam filters
q
limit snow ingestion into the
intake system. When operating in loose powder snow,
check the foam filters periodically to remove any
accumulation of snow.
