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 may be used for such service.

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.

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.

Record maintenance and service in the Maintenance Log at the end of the manual.

TIP

Service and adjustments are important for proper vehicle operation. If you're not familiar with safe service and adjustment procedures, have a qualified dealer 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
Prolonged low speed, heavy load operation

Maintenance Intervals

The maintenance interval charts list required maintenance and inspection based on vehicle hours / miles. Each table states a service that corresponds to the hour / mile chart below. Some items or components may need to be serviced more often due to severe use, such as operation in water, extreme temperatures, or under severe loads. When the vehicle goes beyond 500 hours / 5000 miles, return to the 50 hours / 500 mile chart and start the interval process over.
