IX. Storing Your Engine A. Short-Term/Seasonal Storage I. Clean Engine Before servicing the engine remove the air cleaner cover and/or blower housing. Discard grass clippings, dirt and debris from the following areas: • Cooling Fins • Air Intake Screen • Levers • Linkage • Guards • Carburetor • Head Removing debris will insure adequate cooling, correct engine speed and reduce the risk of fire. II. Fuel Storage ! WARNING NEVER store engine with fuel in fuel tank inside a building with potential sources of ignition such as hot water and space heaters, clothes dryers, electric motors, etc. Failure to do so may result in an explosion and result in death or serious injury. NOTES If engine fuel stored in the gas tank and/or an approved gas container is to be unused without gasoline stabilizer for more than 15-30 days, prepare it for short-term/seasonal storage. See "IV. Fuel Treatment" instructions. If engine fuel is to be stored for more than one season, without gasoline stabilizer, it will gradually deteriorate. Also, if it is stored in the engine's gas tank without gasoline stabilizer it is likely that your carburetor will have gum deposits, a clogged fuel system and will void your warranty. Prepare the fuel for extended storage. See "B. Extended Storage" instructions. Afterward, continue reading instructions below. If you operate the engine during all 4 seasons, it is NOT necessary to lubricate the cylinder bore. III. Fuel System To avoid stale gas and carburetor problems, treat the fuel system in the following method below: NOTES Tecumseh recommends using ULTRA-FRESH™ or Fuel Saver Plus Gasoline Stabilizer plus Fuel System Cleaner as an acceptable method of minimizing formation of fuel gum deposits during storage. This product is available from your Authorized Tecumseh Servicing Dealer. Always follow mix ratio found on stabilizer container. Failure to do so may result in equipment damage. It is NOT necessary to drain stabilized gas from carburetor. IV. Fuel Treatment 1. Add fuel stabilizer according to manufacturer's instructions. 2. Run engine at least 10 minutes after adding stabilizer to allow it to reach carburetor. ! WARNING NEVER store the engine with fuel in the fuel tank inside a building with potential sources of ignition such as hot water and space heaters, clothes dryers, electric motors, etc. NOTE Instead of using a fuel preservative/stabilizer, you can empty the fuel tank as described under "I. Draining Fuel" instructions. See "B. Extended Storage" instructions. B. Extended Storage I. Draining Fuel NOTES Clean debris from engine before draining fuel from carburetor. See "I. Clean Engine" instructions. Afterward, continue reading instructions below. If you have prepared your fuel for short-term storage it is NOT necessary to drain fuel that contains stabilizer from your carburetor. See "A. Short-Term/Seasonal Storage" instructions. ! WARNING To avoid severe injury or death, DO NOT pour fuel from engine or siphon fuel by mouth. 1. To prevent serious injury from fuel fires, empty fuel tank by running engine until it stops from lack of fuel. DO NOT attempt to pour fuel from engine. 2. Run the engine while waiting until the remaining fuel is consumed. ! WARNING NEVER leave the engine unattended when it is running and NEVER run engine in enclosed areas. 3. Begin servicing the cylinder bore. See "II. Oil Cylinder Bore" instructions on page 22. 181-1216-14 Four-Cycle Engine • Vertical Crankshaft • Air-Cooled Page 21
