Exhaust System - Polaris 2000 Universal Snow Owner's Safety And Maintenance Manual

MAINTENANCE
Carburetor Protection During Off Season Storage
Whenever the machine is stored for a period of more than 60 days it is highly rec-
ommended that the engine be fogged with Polaris PN 2870791. Follow the engine
fogging instructions provided on the can. See pages 85-86 for more complete in-
formation about storing your machine during the off season.
When preparing your snowmobile for off season storage we recommend that you
add a fuel conditioner/stabilizer or Premium Carbon Clean (2871326) to the fuel
tank. Follow the instructions on the can. Run the engine for five minutes to get ad-
ditives through the entire fuel system. Then top off with fresh fuel.
If stabilizer is not used, the carburetors should be drained by removing the water
trap drain plugs. Catch fuel in a container or shop cloth. Reinstall plugs securely.
Observe all fire safety rules when draining carburetors. See gasoline warnings on
page 34.
CAUTION:
Using lower than the recommended octane fuels or operating with obstructed fuel
systems will lead to costly engine damage.

Exhaust System

At approximately 2000 miles (3200 km) it is a good idea to check the exhaust sys-
tem for wear or damage. To inspect, allow engine and exhaust system to cool com-
pletely. Open the hood and inspect the muffler and pipes for cracks or damage.
Check for weak or missing retaining springs or damper/support grommets.
WARNING
Exhaust system temperatures can exceed 900° F (500° C). Serious burns may
occur if this inspection is performed without allowing adequate time for the exhaust
system to cool. Never perform this procedure with the engine running.
