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.
INTAKE SCREENS
The intake screens
q
limit snow ingestion into the intake
system. When operating in loose powder snow, check
the screens periodically to remove any accumulation of
snow or ice.
