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 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.
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, or other qualified person. Equivalent parts may be used for emissions-related service.
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
  • Frequent or prolonged operation in dusty environments
  • Short trip cold weather operation
  • Racing or race-style high RPM use
  • Prolonged low speed, heavy load operation
  • Extended idle
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 dealer can assist.
