MAINTENANCE
FUEL FILTER / FUEL LINES
This snowmobile is not equipped with an in-line fuel filter. 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. An authorized
dealer can provide service.
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. If low fuel pressure or reduced engine performance occurs, the
filter may need replacement. An authorized dealer can assist.
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.
NOTICE
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.
COOLING SYSTEM
Inspect the fan intake and outlet ducts for cracks, blockage, obstructions,
damaged seals or loosening of the ducts. Make any necessary repairs promptly.
EXHAUST SYSTEM
Check the exhaust system for wear or damage at approximately 2000 miles
(3200 km). Always allow the engine and exhaust system to cool completely
before inspecting.
WARNING
Hot exhaust system parts can cause burns. Allow adequate time for the
exhaust system to cool. Never perform this procedure with the engine running.
1. Open the side panels and remove the hood. See page 74
2. Inspect the muffler and pipes for cracks or damage.
3. Check for weak or missing retaining springs or damper/support grommets.
CARBURETOR
The number stamped in the end of the main jet indicates the jet size. The jet
installed at the time of manufacture is not necessarily correct for your elevation.
It's your dealer's responsibility to make sure the correct main jet is installed.
