Safe Operation Practices for Walk-Behind Mowers IMPORTANT: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROWING OBJECTS. FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH. CAUTION: Always disconnect spark plug wire and place wire where it cannot contact spark plug in order to prevent accidental starting when setting up, transporting, adjusting or making repairs. WARNING: Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. [. . . ] 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. Wet grass tends to form clumps and interferes with the mulching action. At this time the grass has dried, yet the newly cut area will not be exposed to direct sunlight. For best results, adjust the lawn mower cutting height so that the lawn mower cuts off only the top one-third of the grass blades (See Fig. If the lawn is overgrown it will be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of mulched grass. For extremely heavy mulching, reduce your width of cut by overlapping previously cut path and mow slowly. TO STOP ENGINE • To stop engine, release operator presence control bar. MAX 1/3 TO START ENGINE (See Fig. 9) NOTE: Due to protective coatings on the engine, a small amount of smoke may be present during the initial use of the product and should be considered normal. • To start engine, hold operator presence control bar down to the handle and pull starter handle quickly. 10 Certain types of grass and grass conditions may require that an area be mulched a second time to completely hide the clippings. When doing a second cut, mow across (perpendicular) to the first cut path. Mow north to south one week then change to east to west the next week. This will help prevent matting and graining of the lawn. • MAINTENANCE BEFORE EACH USE Check for Loose Fasteners Clean / Inspect Grass Catcher * Check Tires Check Drive Wheels *** Clean Lawn Mower **** Clean under Drive Cover *** Check Drive Belt / Pulleys *** Check / Sharpen / Replace Blade Lubrication Clean and Recharge Battery ** Check Engine Oil level Change Engine Oil Clean Air Filter Inspect Muffler Replace Spark Plug Replace Air Filter Paper Cartridge Empty fuel system or add Stabilizer AFTER EACH USE EVERY 10 HOURS EVERY 25 HOURS OR SEASON EVERY 100 HOURS BEFORE STORAGE * (if so equipped) ** Electric-Start mowers *** Power-Propelled mowers **** Use a scraper deck to clean under 1 - Change more often if operating under a heavy load or in high outdoor temperatures. 5 - And after each 5 hours of use.
