Fuel Component Percentage Ethanol 10% • DO NOT use leaded fuel. Grain Alcohol (“Gasohol”) 10% • Fuel must be fresh and clean. NEVER use fuel left over from last season or stored for long periods. MTBE (Methyl Tertiary Butyl Ether) 15% ETBE (Ethyl Tertiary Butyl Ether) 15% • NEVER mix oil with fuel.
NOTE Some engine models feature an oil fill plug with an attached dipstick. See Figure 9. 3. Screw oil fill cap or oil fill plug back into oil filler tube. Tighten securely. 4. Unscrew and remove oil fill cap or oil fill plug from oil filler tube. Note oil level. If oil reading on dipstick is below “ADD” mark, slowly add oil to reach “FULL” level. See Figure 7 on page 4. 5. Screw oil fill cap or oil fill plug back into oil filler tube. Tighten securely. 6. Wipe away any spilled oil. 1 2 2 1.
D. Engine Stop Switch Some engines are equipped with an optional Stop Switch. This rocker switch is used to shut off the ignition that supplies the spark plug with power. Pressing the "OFF" position will turn the engine off when it is running. This switch must be in the “ON” position or the engine will not start. See Figure 14. STOP STOP SLOW RUN FAST CHOKE PRIMER Figure 13. Typical Engine Symbols E. Optional Fuel Valve Some engines are equipped with an optional fuel valve. See Figure 12 5 4 6 V.
3. When starting a cold engine, push primer bulb firmly with your thumb 3 times, allowing primer bulb to return completely to original position between pushes. See Figure 15. NOTES Cooler temperatures may require pushing primer bulb firmly with your thumb 5 times. DO NOT use primer to restart a warm engine after a short shutdown. Doing so will flood the engine and may result in equipment malfunction. Figure 15. Engine Primer Bulb DO NOT operate an electric starter for more than 5 seconds each attempt. 4.
B. Engines with Recoil Starters When pulling starter rope, the rope can unexpectedly jerk back toward engine causing serious injury. To avoid this risk, carefully follow these instructions: WARNING If you have an electric starter see "A. Engines with Electric Starters" instructions on page 6. Only one of the following two sections will apply to your engine. If you have a manual recoil starter see Table 4. 4. Grasp starter cord handle. See Figure 19. a. Pull rope out slowly until you feel drag. Table 4.
II. Engine With Choke 1. To avoid carbon monoxide poisoning, be sure engine is outdoors in a well-ventilated area. 2. Move Engine Choke Lever to “FULL CHOKE” position. See Figure 20. STOP STOP SLOW RUN FAST CHOKE PRIMER Figure 17. Typical Engine Symbols NOTE If restarting a warm engine after a short shutdown, move Choke Lever to “NO CHOKE” position. See Figure 20. 3. Move Equipment Control (see manufacturer’s instructions) or Engine Throttle Control to “FAST” position. See Figure 17.
VI. Stopping Your Engine and Short-Term Storage Stop engine according to equipment manufacturer’s instructions. To avoid unsupervised operation of an engine, especially by children, NEVER leave it unattended when it is running. Always turn off the engine after use and remove ignition key, if provided. 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. WARNING Figure 21.
B. Removing Debris from Engine 2 Before each use, remove grass clippings, dirt and debris from the following areas: • Levers and Linkage • Cooling Fins 3 • Air Intake Screen • Guards 1 Removing debris will facilitate adequate cooling, correct engine speed and reduce the risk of fire. See Figure 23. C. Spark Plug Check spark plug yearly or every 100 operating hours. 1. Levers and Linkage 2. Cooling Fins 3. Air Intake Screen 1. Clean area around spark plug. Figure 23. Debris Removal Areas 2.
II. Servicing Paper Filters Paper filters cannot be cleaned and must be replaced once a year or every 100 operating hours; more often if used in extremely dusty conditions. Replacement filters are available at a Authorized Tecumseh Servicing Dealer. 5 4 6 7 NOTE DO NOT put oil on or clean a paper filter. 3 III. Removal and Installation of Air Filters 1. Remove wing nut and cover. See Figure 25. 2. Remove optional foam pre-filter, if present from cover. 3. Remove paper element from base. 8 4.
F. VIII. Transporting Your Engine Alternator (Optional) For alternator related electrical problems such as: • Inoperative starter • Discharged battery • Fuse replacement • Alternator maintenance/repairs See your equipment manufacturer’s instructions and an Authorized Tecumseh Servicing Dealer. G. Carburetor If you think your carburetor needs adjusting, see your nearest Authorized Tecumseh Servicing Dealer. Engine performance should not be affected at altitudes up to 7,000 feet (2,134 meters).
IX. Storing Your Engine III. Fuel System A. Short Term/Seasonal Storage To avoid stale gas and carburetor problems, treat the fuel system in the following method below: I. 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.
II. Oil Cylinder Bore When lubricating cylinder bore, fuel may spray from spark plug hole. To prevent serious injury from fuel fires, follow these instructions: WARNING 1. Disconnect spark plug wire and keep it away from spark plug. See "G. Avoid Accidental Starts" instructions on page 2. See Figures 26 and 27. • Keep the disconnected spark plug wire securely away from metal parts where arcing could occur. Figure 26.
X. Preventing Forest, Brush and Grass Fires Local, state and federal laws may require use of a spark arrester to prevent fires. For example, it is a violation of California Public Resources Code (section 4442) to use or operate engine on any forest-covered, brush-covered or unimproved grass-covered land unless engine is equipped with a spark arrester. Spark arrester must be maintained in effective working order by owner and/or operator.
Before Each Use Scheduled Maintenance Every 5 Hours or Before Each Use 1. Check Oil Level 2. Clean Cooling Fins Every 25 Hours or 3 Months Scheduled Maintenance 1. Change Oil 2.
