II. Oil Cylinder Bore CAUTION When lubricating cylinder bore, fuel may spray from spark plug hole. To prevent serious injury from fuel fires, follow these instructions: 1. Carefully disconnect spark plug wire and keep it away from spark plug. See Figures 25 and 26. • Keep the disconnected spark plug wire securely away from metal parts where arcing could occur. • Carefully attach the spark plug wire to the grounding post, if provided. • Disconnect battery at negative terminal first, if engine is equipped with a DC electric starter. • Turn all engine switches to "OFF" position. • Remove ignition key, if provided. 2. Remove spark plug. 3. Squirt 1oz. (30 ml) of clean engine oil into spark plug hole. 4. Cover spark plug hole with rag to prevent fuel from spraying from spark plug hole when starter rope is pulled. NOTES For engines equipped with recoil starters proceed to Step 5. For engines equipped with electric starters proceed to Step 6. 5. Grasp starter cord handle: a. Pull starter cord handle out slowly using a full arm stroke. b. Repeat once. (This will distribute oil throughout the cylinder to prevent corrosion during storage.) 6. Remove rag covering spark plug hole. 7. Install spark plug. 8. Carefully disconnect spark plug wire from grounding post, if provided. 9. Connect spark plug wire to spark plug before attempting to start engine. III. Oil Change oil if NOT changed within the last 3 months. See "A. Checking and Changing Oil" instructions on page 10. IV. Battery See equipment manufacturer's instructions for proper battery storage, if machine is equipped with a battery. Figure 25. Typical Spark Plug Connection Figure 26. Disconnecting/Connecting Spark Plug 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. To determine if your engine has a spark arrester, locate the muffler on your engine. For example, the muffler discharge will have a spark arrester cover that reads "Screen Type 36085". If your engine does NOT have a spark arrester, you may purchase one from your Authorized TecumsehPower Servicing Dealer. In some cases the muffler may need to be replaced to allow the spark arrester to be installed. 181-1132-14 Four-Cycle Engine • Vertical Crankshaft • Air-Cooled Page 15
