ADULT SECTION

Emission Control Information

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

repair the emission control devices or systems on your snowmobile.

Emission Control Label

Your snowmobile is equipped at the time of sale with an emission con-

trol information (ECI) label and a factory-installed emissions informa-

tion hang tag. These items are required by U.S. Environmental 

Protection Agency regulations. The ECI label is permanently affixed to 

either the right side of the tunnel or the engine recoil cover. The ECI 

label should not be removed, even after you purchase the snowmobile. 

You may remove the factory-installed emissions information hangtag, 

which is intended solely for your use in making a purchasing decision.

Emission Control Maintenance Requirements

Your snowmobile is certified to operate on gasoline with a minimum 

octane level of 87 (R+M)/2. The emission control system designation 

per SAE J1930 is EM. If your snowmobile is equipped with a check 

engine light and it comes on, you must take your snowmobile to a quali-

fied dealer for diagnostic service. Specifications and adjustments for 

engine tune-ups are located in the Service Manual, which is available to 

your qualified service technician. Reverse (if equipped) must not be 

engaged during engine tune-ups.

Owner's Responsibilities

Please read the Snowmobile Engine Emissions Limited Warranty on 

page 92, and read the maintenance section of your owner's manual. You 

are responsible for ensuring that the specified maintenance is per-

formed, including the emission-related maintenance outlined in these 

sections of the manual.
Polaris considers the specified maintenance for the spark plugs and oil 

changes to be critical emission-related maintenance. Any qualified 

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

emission control devices or systems on your snowmobile. Polaris rec-

ommends that you contact an authorized Polaris dealer to perform any 

service that may be necessary.

Maintenance

Polaris Recommended Maintenance Program

To ensure many trouble-free miles of snowmobiling enjoyment, follow 

recommended regular maintenance and perform service checks as out-

lined in this manual. Record maintenance and service in the Mainte-

nance Log beginning on page 94.
The recommended maintenance schedule for your snowmobile calls for 

a service and maintenance inspection at 50 hours, at 100 hours and at 

150 hours. These inspections should be performed by a qualified service 

technician. 
All necessary replacement parts and labor incurred, with the exception 

of authorized warranty repairs, become the responsibility of the regis-

tered owner. If, during the course of the warranty period, part failures 

occur as a result of owner neglect in performing recommended regular 

maintenance, the cost of repairs are the responsibility of the owner. 
Personal safety is critical when attempting to service or make adjust-

ments to your snowmobile. If you're not familiar with safe service or 

adjustment procedures and the use of tools, or if you don't feel comfort-

able performing these tasks yourself, contact an authorized Polaris 

dealer for service.

CAUTION

Hot components can cause damage to plastic. Always make sure the exhaust 

system and engine have cooled before tipping the snowmobile on its side for 

service or inspection.
