MAINTENANCE
PERIODIC MAINTENANCE
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
safe, reliable condition. 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
171. 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. 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
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.
