MAINTENANCE

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.

NOTICE: Operating the snowmobile with incorrect jetting can result in serious 

engine damage. Have your POLARIS dealer perform all carburetor 
adjustments to ensure all adjustments are done correctly.

Carburetor Adjustments

The frequency at which the carburetors are synchronized or balanced is 
important. Properly adjusted carburetors can greatly improve engine 
performance, fuel economy, engine life, and reliability.

If you notice any of the following conditions, the carburetor may need 
adjustment:
• Hard starting
• Poor idle
• Overheated pistons and cylinder walls
• Plug fouling
• Poor engine response to various throttle valve openings

MAINTENANCE

Fuel Filter/Fuel Lines

The fuel filter is located inside the fuel tank. This component requires 
no maintenance.

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.

Oil Filter

The oil filter is located at the side of 
the oil tank. Have your dealer change 
the oil filter and bleed the system 
annually or every 1000 miles (1600 
km). 

Tip: The direction of the arrows indicates 

the direction of flow through the filter.

MAINTENANCE

Exhaust System

Check the exhaust system for wear or damage at approximately 1000 
miles (1600 km). To inspect, allow the engine and exhaust system to 
cool completely. Open the hood and inspect the muffler and pipes for 
cracks or damage. Check for weak or missing retaining springs or 
damper/support grommets.

CAUTION! Hot exhaust system parts can cause serious burns. Allow adequate 
time for the exhaust system to cool. Never perform this procedure with the 
engine running.

Drive Chain Tension

Your Widetrak is equipped with an automatic chain tensioner. No 
maintenance or inspection should be necessary.

MAINTENANCE

Brakes

Hydraulic Brake Inspection

Inspect the brake lever reserve before each use of the snowmobile. See 
page 41.

Brake pads must be replaced when the brake pad material becomes 
thinner than the backing plate, approximately 1/16 inch (1.5 mm). A kit 
is available for replacing brake pads. See your dealer.

WARNING! Brake failure during operation can result in serious injury or death. 
Properly functioning brakes are vital to your safety. Be sure the brake pads do 
not drag on the disc and that brake lever travel is not excessive. Always replace 
brake pads when the brake pad material becomes thinner than the backing plate 
(approximately 1/16 inch/1.5 mm).
