MAINTENANCE

Periodic Maintenance Chart

Any qualified repair shop or person may maintain, replace or repair 

the emission control devices or systems on your vehicle. An 

authorized POLARIS dealer can perform any service that may be 

necessary for your vehicle. POLARIS also recommends POLARIS 

parts for emissions-related service, however equivalent parts can be 

used. 
It is a potential violation of the Clean Air Act if a part supplied by an 

aftermarket parts manufacturer reduces the effectiveness of the 

vehicle’s emission controls. Tampering with emission controls is 

prohibited by federal law.
Owners are responsible for performing the scheduled maintenance 

identified in this owner’s manual.
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.

MAINTENANCE

Periodic Maintenance Chart

Inspect, clean, lubricate, adjust and replace parts as necessary. When 

inspection reveals the need for replacement parts, genuine POLARIS 

parts are available from your POLARIS dealer. Equivalent parts may 

be used for emissions-related service.
Record maintenance and service in the Maintenance Log beginning on 

page 115.
Service and adjustments are important for proper vehicle operation. If 

you're not familiar with safe service and adjustment procedures, a 

qualified dealer can perform these operations.
Vehicles subjected to heavy or severe use patterns 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 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 the oil sump or 

crankcase. Change oil immediately if the oil level begins to rise. 

Monitor the oil level, and if it continues to rise, discontinue use and 

determine the cause. Your POLARIS dealer can assist.
