Mutcher plug Mulcher door BEFORE STARTING ENGINE Open mulcher door Discharge deflector OIL Your lawn mower is shipped without oil in the engine. • Be sure mower is level and area around oil fill is clean. • Remove engine oil cap and fill to the full line on the dipstick. NOTE: Allow oil to settle down into engine for accurate reading. • Engine holds 20 ozs. of oil. For type and grade of oil to use, see "ENGINE" in maintenance section of this manual. • Pour oil slowly. Do not over fill. 8 • Check oil level before each use. Add oil if needed. Fill to full line on dipstick. • To read proper level, tighten engine oil cap each time. • Reinstall engine oil cap and tighten. • Change the oil after every 25 hours of operation or each season. You may need to change the oil more often under dusty, dirty conditions. ADD GASOLINE NOTE: Before filling fuel tank, remove and discard the debris plug that is inside the tank. • Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane(Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. _I,WARNING: Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the fuel tank, start the engine and let it run until fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instructions for additional information. Never use engine or carburetor cleaner products in fuel tank or permanent damage may occur. ACAUTION: Fill to bottom of gas tank filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. Gasoline TO START ENGINE • To stad a cold engine, push primer three (3) times before trying to stad. Use a firm push. This step is not usually necessary when starting an engine which has already run for a few minutes. • Hold operator presence control bar down to the handle. • To stop engine, release operator presence control bar. NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather over priming may cause flooding and engine will not stad. If you do flood engine wait a few minutes before attempting to stad and do not repeat priming steps. Engine oil cap filler cap (Discard debris plug inside) 9 MOWINGTIPS MULCHING MOWING TIPS • Under certain conditions, such as very tall grass, it may be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of grass clippings. It may also be necessary to reduce ground speed and/or run the lawn mower over the area a second time. • For extre_nely heavy cutting, reduce the width of cut by overlapping previously cut path and mow slowly. • For better grass bagging and most cutting conditions, the engine speed should be set in the fast position. • Pores in cloth grass catchers can become filled with dirt and dust with use and catchers will collect less grass. To prevent this, regularly hose catcher off with water and let dry before using. • Keep top of engine around starter clear and clean of grass clippings and chaff. This will help engine air flow and extend engine life. IMPORTANT: For best performance, keep mower housing free of built-up grass and trash. See "Cleaning" in MAINTENANCE section of this manual. 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 recuttingaction of the blades. Avoid cutting your lawn when itis wet. Wet grass tends to form clumps and interferes with the mulching action. The best time to mow your lawn is the early afternoon. At this time the grass has dried and the newly cut area will not be exposed to the direct sun. 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. 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. 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 or perpendicular to the first cut path. Change your cutting pattem from week to week. Mow north to south one week then change to east to wast the next week. This will help prevent matting and graining of the lawn. 10 MAINTENANCE M o _ SCHEDULE _,/,'____°_._Y Check for Loose Fasteners Clean/Inspect Grass Catcher _ (If Equipped) Clean Lawn Mower _ Clean Under Drive Cover (Power-Propelled Mowers) _ I_ _ heck drive beWpu!leys g Check/Sharpen/Replace Blade (Power.Propelled Mowers) Lubrication Chart Clean Battery/Recharge /Electdc Start Mowers I E Check ChangeEngine EngineOil OilLevel 3 I_ I_ I_4 1_#'1,2 G Inspect Muffler clean Air Filter _ N Clean orAir Replace Spark Cartridge Plug Replace Filter Paper If2 2 I - Change more often when operatingunder a heavy load or in highambient temperatures. 2 - Service more often when operatingin dirtyor dustyconditions. 3 - Replace i_ades more often when mowingin sandy soil. 4 - Charge 48 hours at endof season.
