Cleaning and Storage
Storage Tips
NOTICE: Starting the engine during the storage period will disturb the
protective film created by fogging and damage could occur. Never
start the engine during the storage period.
Clean the Exterior
Make any necessary repairs and clean the vehicle as recommended. See
page 134.
Stabilize the Fuel
1. Fill the fuel tank.
2. Add POLARIS Carbon Clean Fuel Treatment or POLARIS Fuel
Stabilizer or equivalent fuel treatments or stabilizers. Follow the
instructions on the container for the recommended amount. Carbon
Clean removes water from fuel systems, stabilizes fuel and removes
carbon deposits from pistons, rings, valves and exhaust systems.
3. Allow the engine to run for 15-20 minutes to allow the stabilizer to
disperse through the entire fuel delivery system.
