MAINTENANCE
Storage
Proper preparation of the engine and fuel system is vital to the prevention of rust and
corrosion of engine parts.
Whenever the machine is stored for a period of more than 60 days, the engine must
be fogged, following the fogging instructions on the can.
Always add a fuel conditioner/stabilizer to the fuel tank. Run the engine for five min-
utes to get the additives through the entire fuel system and top off with fuel.
Fuel additive products are available through your Polaris dealer.
NOTE: Before storing the machine, add lubricant to the fuel in the tank at a 40:1 ratio
and then run the engine for three to five minutes. This will lubricate the fuel pump
diaphragm to keep it flexible and help prevent loss of prime.
Jet restriction caused by improper storage can cause lean conditions and very poor
slow speed driving quality.
