MAINTENANCE
FALL TUNE-UP
For maximum performance, your POLARIS dealer can perform a fall service
tune-up. Their experienced and trained service technicians will keep your
snowmobile in peak operating condition.
TRANSPORTING THE SNOWMOBILE
Whenever the snowmobile is transported:
1. Turn the fuel valve off. See page 60.
2. Be sure the fuel cap and oil cap are installed correctly.
3. Always tie the snowmobile to the transporting unit securely using suitable
straps.
4. Remove the ignition key to prevent loss.
SUMMER STORAGE GUIDE
TREATING THE FUEL SYSTEM
As the riding season draws to a close, Polaris recommends riders begin treating
their snowmobile's fuel system with Polaris Carbon Clean or similar
commercially-available fuel stabilizer.
Treating the fuel system with Carbon Clean during the last few rides of the
season ensures the entire fuel system is treated. Then, when it comes time to
store the snowmobile, all the rider has to do is completely fill the fuel tank with
fresh, non-oxygenated fuel and treat the new fuel with Carbon Clean.
It is also recommended riders use non-oxygenated fuel during the last rides of
the season as non-oxygenated fuel stores better than oxygenated fuel and
resists water vapor absorption.
If the rider was unable to treat the fuel system and/or use non-oxygenated fuel at
the end of the riding season, the rider should do the following:
1. The rider should consume as much fuel in the fuel tank as possible during
the last rides of the season.
2. When performing the summerization storage procedures, fill the fuel tank
completely with non-oxygenated fuel. Note that most oxygenated fuels
contain ethanol. Since ethanol is hydroscopic, oxygenated fuel will absorb a
small amount of water vapor during the storage season and more so in
humid locations. Completely filling the tank with non-oxygenated fuel
minimizes water vapor absorption during the storage period and limits the
amount of air and water vapor that can accumulate in the tank.
3. Treat the fuel in the fuel tank with the recommend amount of Polaris Carbon
Clean. The recommended mixing ratio is outlined on the bottle label.
