MAINTENANCE

Intake Filters

The intake foam filters limit 

snow ingestion into the intake 

system. When operating in loose 

powder snow, check the foam 

filters periodically to remove 

any accumulation of snow.

Fuel Pump

All fuel pump service must be 

performed by an authorized 

Polaris dealer. Do not attempt to 

service the fuel pump.

Fuel Filter/Fuel Lines

See your Polaris dealer for replacement of the fuel filter. Have the filter 

replaced initially at 1000 miles (1600 km), then every 2000 miles (3200 

km) thereafter.
Inspect the fuel lines regularly for signs of deterioration or damage. 

Always check fuel line condition after periods of storage. Normal dete-

rioration 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.

MAINTENANCE

Spark Plugs

Spark Plug Recommendations

A new engine can cause temporary spark plug fouling due to the preser-

vative added during the assembly process. Avoid prolonged idle speeds, 

which cause plug fouling and carbonization.
Refer to your Owner's Manual Supplement for the specific spark plug to 

be used in your snowmobile.
Change the spark plugs every 2000-2500 miles (3200-4000 km).
• Use recommended spark plugs with the proper gap.
• Use only resistor-type spark plugs.
• Torque spark plugs to 18-22 ft. lbs. (24-30 Nm).
• Always carry spare spark plugs.

NOTICE: Using non-recommended spark plugs can result in serious engine 

damage. A spark plug with a heat range too high will always cause 

engine damage if the engine is operated in conditions more severe 

than intended for that plug. Always use the spark plugs recommended 

for your snowmobile. See your Owner’s Manual Supplement.

Spark Plugs

Spark Plug Inspection

Spark plug condition is indicative of engine operation. The spark plug 

firing end condition should be read after the engine has been warmed up 

and the vehicle has been driven at higher speeds. Immediately check the 

spark plug for correct color.

CAUTION! A hot exhaust system and engine can cause burns. Wear 

protective gloves when removing a spark plug for inspection.

1. Remove the left side panel.
2. Remove the spark plug cap.
3. Using the special wrench provided in the tool pouch, rotate the 

spark plug counter-clockwise to remove.

4. Reverse the procedure for spark plug installation. Torque to specifi-

cation.

5. Reinstall the spark plug cap.

Spark Plug Condition

Normal Plug
The normal insulator tip is gray, tan or light brown. There will be few 

combustion deposits. The electrodes are not burned or eroded. This indi-

cates the proper type and heat range for the engine and the service.

TIP: The tip should not be white. A white insulator tip indicates overheating, 

caused by use of an improper spark plug or incorrect carburetor/throttle 

body adjustments.

Wet Fouled Plug
The wet fouled insulator tip is black. A damp oil film covers the firing 

end. There may be a carbon layer over the entire nose. Generally, the 

electrodes are not worn. General causes of fouling are excessive oil or 

use of non-recommended injection oil.

MAINTENANCE

Oil Lines

Inspect oil line condition every 1000 miles (1600 km).

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 fil-

ter.
