John Deere LA105 — Fuel:

STORAGE Storage Storing Safety c CAUTION: Avoid injury! Fuel vapors are explosive and flammable. Engine exhaust fumes contain carbon monoxide and can cause serious illness or death: • Run the engine only long enough to move the machine to or from storage. • Machine fires and structure fires can occur if a machine is stored before allowing it to cool, or if debris is not removed from around the engine and muffler, or if stored near combustible materials. • Do not store vehicle with fuel in the tank inside a building where fumes may reach an open flame or spark. • Allow the engine to cool before storing the machine in any enclosure. Preparing Machine for Storage 1.

Repair any worn or damaged parts. Replace parts if necessary. Tighten loose hardware. 2. Repair scratched or chipped metal surfaces to prevent rust. 3. Remove grass and debris from machine. 4. Clean under the deck and remove grass and debris from inside chute and bagger. 5. Wash the machine and apply wax to metal and plastic surfaces. 6. Run machine for five minutes to dry belts and pulleys. 7. Apply light coat of engine oil to pivot and wear points to prevent rust. 8. Lubricate grease points and check tire pressure. Preparing Fuel and Engine For Storage Fuel: If you have been using “Stabilized Fuel,” add stabilized fuel to tank until the tank is full. NOTE:

Filling the fuel tank reduces the amount of air in the fuel tank and helps reduce deterioration of fuel. If you are not using “Stabilized Fuel:” 1. Park machine safely in a well-ventilated area. (See Parking Safely in the SAFETY section.) NOTE: Try to anticipate the last time the machine will be used for the season so very little fuel is left in the fuel tank. 2. Turn on engine and allow to run until it runs out of fuel. 3. For machines equipped with key switch, turn key to off position. IMPORTANT: Avoid damage! Stale fuel can produce varnish and plug carburetor or injector components and affect engine performance. 4. Mix fresh fuel and fuel stabilizer in separate container.

Follow stabilizer instructions for mixing. • Add fuel conditioner or stabilizer to fresh fuel before filling tank. 5. Fill fuel tank with stabilized fuel. 6. Run engine for a few minutes to allow fuel mixture to circulate through Storage - 42 IF CHECK Patches Of Grass Uncut Travel speed too fast. Engine rpm not at wide open throttle.
