MAINTENANCE

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 hangtag. 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 125, 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.

You must inspect the air intake system on your snowmobile prior to 
each use (including the airbox foam filter and hood foam filters) and 
clean these components as necessary. Polaris considers the specified 
maintenance for the spark plugs, oil changes, air intake system and 
exhaust valves to be critical emission-related maintenance. The speci-
fied maintenance for the fuel filter is recommended additional emission-
related maintenance. Polaris recommends 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 127.

The recommended maintenance schedule on your snowmobile calls for 
service and maintenance inspections at 150 miles (240 km), 500 miles 
(800 km) and 1000 miles (1600 km). These inspections should be per-
formed by a qualified service technician. For continued optimum perfor-
mance and component life, continue maintenance checks at 1000 mile 
(1600 km) intervals.

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.
