ADDGASOUNE • Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. _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 8 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 extremely 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. Clean UNDERSIDE OF MOWER HOUSING after each use. 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 recutting action of the blades. • Avoid cutting your lawn when it is 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 west the next week. This will help prevent matting and graining of the lawn. 1/3 9 MAINTENANCE SCHEDULE FILL IN DATES AS YOU COMPLETE REGULAR SERVICE Check for Loose Fasteners _ERVICE DATES ¥# (If Equipped) CleardlnspectGrass Catcher !_ (_ Clean Clean Under Lawn Mower Drive Cover (Power-Propelled Mowers) !_# W Check drive belt/pulleys (Power-PropenedMowers) R Check/Sharpen/Replace Blade I11 1_3 LubricationChad Clean Battery/Recharge (Electric Start Mowers) E Check OilOilLevel ChangeEngine Engine Ip# I_ I_ I#/ 1_4 _1,2 G Inspect Muffler Clean Air Filter _12 N Clean orAir Replace Replace Filter Spark Paper Plug Cadrtdge f_'2 I 2 3 4 - Change more offe_ when operating under a heavy load or in high ambient lernperalures. ° Service n_ore often when operating in dirty or dusty conditions. - Replace blades more often when mowing in sandy soil. - Charge 48 hours at end of season. GENERAL LUBRICATION RECOMMENDATIONS The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negligence.

Be sure key in adapter and crankshaft keyway are aligned. • Position blade on the blade adapter aligning the two (2) holes in the blade with the raised lugs on the adapter. • 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. • The recommended tightening torque is 35-40 ft. Ibs. IMPORTANT: Blade bolt is grade 8 heat treated. 11 TO SHARPEN BLADE NOTE: We do not recommend sharpening blade - but if you do, be sure the blade is balanced. Care should be taken to keep the blade balanced. An unbalanced blade will cause eventual damage to lawn mower or engine. • The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower. • To check blade balance, drive a nail into a beam or wall. Leave about one inch of the straight nail exposed. Place center hole of blade over the head of the nail. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced. Crank shaft Blade keyway Ke Bolt Lockwasher Hardened washer Trailing edge Blade adapter Crank shaft GRASS CATCHER • The grass catcher may be hosed with water, but must be dry when used. • Check your grass catcher often for damage or deterioration. Through normal use it will wear. If catcher needs replacing, rep_ce only with a manufacturer approved replacement catcher. Give the lawn mower model number when ordering. ENGINE NOTE: Although multi--viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi--viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil. Change the oil after every 25 hours of operation or at least once a year if the lawn mower is not used for 25 hours in one year.
