MAINTENANCE
PERIODIC MAINTENANCE CHART
Periodic Maintenance Overview
Careful periodic maintenance will help keep your vehicle in the safest, most reliable condition. Inspection,
adjustment and lubrication of important components are explained in the periodic maintenance chart.
Inspect, clean, lubricate, adjust and replace parts as necessary. When inspection reveals the need for replacement
parts, use genuine Polaris parts available from your dealer.
NOTE: Service and adjustments are critical. If you’re not familiar with safe service and adjustment procedures, have
qualified dealer perform these operations.
Maintenance intervals in the following chart are based upon average riding conditions and an average vehicle speed
of approximately 10 miles per hour. Vehicles subjected to severe use must be inspected and serviced more
frequently.
Severe Use Definition
• Frequent immersion in mud, water or sand
• Racing or race-style high RPM use
• Prolonged low speed, heavy load operation
• Extended idle
• Short trip cold weather operation
Pay special attention to the oil level. A rise in oil level during cold weather can indicate contaminants collecting in
oil sump or crankcase. Change oil immediately if the oil level begins to rise. Monitor the oil level, and if it continues
rise, discontinue use and determine the cause or see your dealer.
Maintenance Chart Key
The following symbols denote potential items to be aware of during maintenance:
■ = CAUTION: Due to the nature of these adjustments, it is recommended this service be performed by
authorized Polaris dealer.
◆ = SEVERE USE ITEM -- See Above
NOTE: Inspection may reveal the need for replacement parts. Always use genuine Aeon parts.
Improperly performing the procedures marked with a■
could
result in component failure and lead to serious injury
or death. Have an authorized Polaris de
aler perform these
services.

Periodically inspect the torque of all fasteners in accordance with the maintenance schedule. Check that all cotter pins are in
place. Refer to specific fastener torques listed in each chapter.
Standard Torque Specifications
The following torque specifications are to be used as a general guideline. There are exceptions in the steering, suspension, and
engine areas. Always consult the exploded views in each manual section when available for torque values of fasteners before
using standard torque.

MAINTENANCE
FUEL SYSTEM AND AIR INTAKE
Fuel System Safety

Throttle Stop Speed Control System
Use the following procedure to control how far the throttle
opens.
IMPORTANT: This procedure should be performed
by consumers only when they determine that their
child is capable of handling the additional speed.
1. Loosen the jam nut.
2. Turn the screw inward to reduce speed or outward to
increase speed.
3. Tighten the jam nut after adjusting.
2.7
MAINTENANCE

Choke Cable Adjustment
Verify free play of 1.6-4.76 mm (1/16-3/16”) and smooth
operation of choke cable.
Adjustments to the freeplay can be made by loosening the
choke cable adjustment in or out to gain the desired
freeplay.
If smooth choke operation is not obtainable, inspect choke
cable for kinks or sharp bends in routing.
Idle Speed Adjustment
1. Start engine and warm it up thoroughly.
2. Adjust idle speed by turning the slide adjustment screw
in (clockwise) to increase or out (counterclockwise) to
decrease RPM. (Refer to illustration).
Idle Speed
1500 ± 100
Fuel Lines
1. Check fuel lines for signs of wear, deterioration, damage, or leakage. Replace if necessary.
2. Be sure fuel lines are routed properly and secured with cable ties.
3. Replace all fuel lines every two years.
2.8

MAINTENANCE
Air Screw Adjustment
1. Set idle speed to specification. Always check throttle
cable
freeplay after adjusting idle speed and adjust if necessary.
2. To adjust the mixture screw setting, you will need to use
the Adjustment Screwdriver. Slowly turn the mixture
screw clockwise until engine idle RPM begins to decrease.
Stop turning at this point.
3. Slowly turn mixture screw counterclockwise until idle
speed returns to maximum RPM. Continue turning
counterclockwise until idle RPM begins to drop. Stop
turning at this point.
4. Center the mixture screw between points in Step 2 and
3.
5. Readjust idle speed if not within specification.
Fuel Filter
The fuel filter should be replaced in accordance with the
“Periodic Maintenance Chart” or whenever sediment is
visible
in the filter.
Fuel Filter Location - Located in-line between fuel
valve and carburetor inlet.
To service the fuel filter:
1. Shut off fuel supply at fuel valve.
2. Remove line clamps at both ends of the filter.
3. Remove fuel lines from filter.
4. Install new filter and clamps onto fuel lines.
5. Turn fuel valve to ‘ON’.
6. Start engine and inspect for leaks.
2.9
Air Screw

MAINTENANCE
Carburetor Draining
The carburetor float bowl should be drained periodically to
remove accumulated moisture or sediment from the bowl, or
before extended periods of storage.
1. Turn fuel valve to the ‘OFF’ position.
2. Place a container beneath the bowl drain hose.
3. Loosen drain screw and allow fuel in the float bowl and fuel
line to drain completely.
4. Inspect the drained fuel for water or sediment.
5. Tighten drain screw.
6. Turn fuel valve to “ON”.
7. Check for fuel leaks.
8. Start engine and re–check for leaks.

2.10
MAINTENANCE
Air Filter Service
1. Release the screw and remove the cover.
2. Remove the foam air filter. Wash the foam filter in warm
soapy water, then rinse and let it dry. If the filter is damaged,
install a new foam filter.
3. Apply a commercially available foam filter oil to the foam
filter.
4. Reinstall the screen, foam filter and air box cover. Secure
the clips.
5. The inlet pipe must toward rear of vehicle.

2.11
MAINTENANCE
ENGINE
Transmission Oil Level
Maintain the oil level within the safe range on the filler plug.
Do not overfill.
To check the oil level:
1. Position the vehicle on a level surface.
2. Remove the filler plug.
3. Check oil lever by glass widow.
NOTE: Rising oil level between checks in cool
weather driving, can indicate moisture collecting in
the oil reservoir. If the oil level is over the full mark,
change the oil.
4. Add the recommended oil as needed.
NOTE: Do not fill the over the normal oil operating
range. Filling over the normal operating range could
cause a mist of oil to enter the air box.
5. Reinstall the filler plug.
Transmission Oil Change
1. Position the vehicle on a level surface.
2. Clean area around the drain plug.
3. Run engine two to three minutes until warm.
4. Stop the engine.
5. Place a drain pan beneath the mission case.
6. Remove the drain plug. Allow the oil to drain completely.
7. Inspect the O-ring on drain plug, replace if needed.
NOTE: The sealing surfaces on the drain plug and
crankcase should be clean and free of burrs, nicks
or scratches.
11. Remove the dipstick. Add 30 oz. (900 ml) of recommended oil. Do not overfill.
12. Reinstall the filler plug.
13. Start the engine. Allow it to idle for one to two minutes.
