[. . . ] WARNING: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling. SAFETY RULES • • • • • • • • • Stop the blade(s) when crossing gravel drives, walks, or roads. Stop the engine (motor) whenever you leave the equipment, before cleaning the mower or unclogging the chute. Shut the engine (motor) off and wait until the blade comes to complete stop before removing grass catcher. [. . . ] Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Empty the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. • MULCHING MOWING TIPS IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE “CLEANING” IN MAINTENANCE SECTION OF THIS MANUAL. • • • TO STOP ENGINE • To stop engine, release operator presence control bar. In warmer weather over priming may cause flooding and engine will not start. If you do flood engine, wait a few minutes before attempting to start and do not repeat priming steps. The special mulching blade will recut the grass clippings many times and reduce them in size so that as they fall onto the lawn they will disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quickly to provide nutrients for the lawn. Always mulch with your highest engine (blade) speed as this will provide the best recutting action of the blades. Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage. 3. Be sure the trailing edge of blade (opposite sharp edge) is up toward the engine. Install the blade bolt with the lock washer and hardened washer into blade adapter and crankshaft. Use block of wood between blade and lawn mower housing and tighten the blade bolt, turning clockwise. IF BOLT NEEDS REPLACING, REPLACE ONLY WITH APPROVED BOLT SHOWN IN THE REPAIR PARTS SECTION OF THIS MANUAL.
