For type and grade of oil to use, see "ENGINE" in Maintenance section of this manual. • Pour oil slowly. Do not over fill. * 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 • Fillfuel 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 problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the 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 the 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. TO START ENGINE • To start a cold engine, push primer three (3) times before trying to start.

Gasoline filler cap Engine oil cap 8 MOWlNGTIPS 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. • When using a rear discharge lawn mower in moist, heavy grass, clumps of cut grass may not enter the grass catcher. Reduce ground speed (pushing speed) and/or run the lawn mower over the area a second time. • If a trail of clippings is left on the right side of a rear discharge mower, mow in a clockwise direction with a small overlap to collect the clippings on the next pass. • 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 wgl disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quicldyto 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 aftemoon. At this time the grass has dried and the newly cut area will not be exposed to the _rect 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 dumps of mulched grass. For extremely heavy mulching, reduce your width of cut, mow slowly and raise the rear of the lawn mower one wheel adjuster setting higher than tbe fronL • Certain types of grass and grsss conditions may require that an area be mulched a second time to completely hide the d_W_ngs.Wh_ ddng a soco_ c_ mow a_oesorpeq_endk_ to_ first cutpath. • Change your cuttingpattern from week to week. Mow north to south one weak then change to east to west the next week. This will prevent matUng and the lawn. 1/3 9 of MAINTENANCE SCHEDULE _ _'_ ,'_7_7"_._0___Y AS YOUCOMPLETE ICE DATES R aU RSERV,CE Check for Loose Fasteners Clean/Inspect Grass Catcher _ I_ oa Clean Under Lawn Mower Drive Cover W R Check ddve belt/pulleys IPower-Propelled Mowers) (Power-Propelled Mowers} Check/Sharpen/Replace Blade .j 3 LubricationChart Clean Battery/Recharge /Electric Start Mowers_ E Check En_lineOil Level Change Engine Oil 1/ I/4 1/ I/'1: Clean Air Filter Inspect Muffler N 12 3 4. clean orAir Replace Spark Cartridge Plug Replace Filter Paper = Change more often when operating under a heavy load or in high ambient temperatures, Sep/ice more often when of_ragng In dirty or dusty conditions.
