Storage75ESU12430Long-term storage requires some preventiveprocedures to guard against deterioration.CleaningThoroughly clean the snowmobile, inside andout, to remove the corrosive salts and acidsthat can accumulate. Use Yamaha Mud,Grease, and Engine Cleaner, or an equivalentproduct, to loosen mud, grease, and grime.Wash with mild soap, then rinse and dry com-pletely.LubricationLubricate moving parts, suspension linkage,and pivot points. Use the grease or lubricantspecified in the MAINTENANCE section, orYamaha Lube-Zall general-purpose lubricant.Proper lubrication fights corrosion while it re-duces friction.Fuel systemAdd Yamaha Fuel Stabilizer and Conditioner,or an equivalent stabilizer, to the fuel tank tohelp prevent fuel oxidation and gum and var-nish deposits, and to inhibit corrosion in thefuel system and injectors. In areas where ox-ygenated fuel (gasohol) is used, consult aYamaha dealer.EngineProper storage of the engine is essential toprevent costly rust and corrosion damage tointernal engine components. This is more im-portant in areas where oxygenated fuel (gas-ohol) is used, because the alcohol content inthe fuel increases the chance for water to en-ter the engine. Use Yamaha Stor-Rite EngineFogging Oil, or an equivalent fogging oil, toprotect both the combustion chamber andcrankshaft from corrosion. An alternate meth-od is to remove the intake silencer and squirtoil into the throttle bodies while the engine isrunning.CAUTION:ECS00680Do not attempt to store the snowmobile bysimply starting the engine occasionallyduring the storage period. This can causemore harm than good! Moisture and acidsform during combustion which can actual-ly increase the chance for corrosion dam-age during the storage period.Surface protectionApply a coat of wax to painted surfaces. Applysuitable protectants to the exterior of the en-gine, drive track, and to other metal, plastic,and rubber parts.BatteryWARNINGEWS00610 Never smoke around the battery while itis being charged. Sparks may ignite thehydrogen gas created by the battery. Disconnect the negative lead first, thenthe positive lead from the battery. Connect the positive lead first, then thenegative lead to the battery when install-ing the battery. Never connect the battery to or discon-nect it from the snowmobile while it isbeing charged. Sparks may ignite thehydrogen gas created by the battery. Make sure that the battery terminals aretight.Remove the battery from the snowmobile.Store it in a cool, dry place that is above 0 °C(32 °F), but less than 30 °C (90 °F). Check thecondition of the battery once a month, andcharge it as necessary.CAUTION:ECS00690 Always keep the battery charged. Stor-ing a discharged battery can cause per-manent battery damage.
