You may need to change the oil more often under dusty, 6 dirtycondtions. ADD GASOUNE • 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. AWARNING: 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. A, CAUTION: 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 MOWING • 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. • For side discharge lawn mowers, cutting in a counter-clockwise direction, starting at the outside of the area to be cut, spreads grass clippings more evenly and puts less load on the engine. To keep clippings off of walkways, flower beds, etc., make the first cuts in a clockwise direction. • 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. ENGINE • To start a cold engine, push primer five (5) times before trying to start. 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 and pull starter handle quickly. Do not allow starter rope to snap back. • 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 start. If you do flood engine, wait a few minutes before attempting to start and do not repeat priming steps.

Also,the mulchedgrass will biodegrade quicklyto provide nutrients for the lawn. Always mulchwith your highestengine (blade) speed as this will providethe best recuttingactionof the blades. • Avoidcuttingyour lawnwhen itis wat. Wet grasstends to form dumps and interferes withthe mulchingaction. The best time to mow your lawn is the early afternoon. At this time the grass has dried and the newiy cutarea will not be exposedto the direct sun. • For best reeults,aa_ustthe lawn mower cuttingheightso thatthe lawn mowercuts off onlythe top one-thirdof the grass blades. If thelawn is overgrownitwilibe necessaryto raleethe beight of cutto reduce pushingeffortand to keep from overloadingthe engine and leaving dumps of mulchedgrass. For extremely heavy mulching,reduce yourwidthof cut by overlappingpreviouslycutpath and mowslowly. • Certain typesof grass and grass conditions may requirethat an area be mulched a secondtime to completelyhidethe clippings. When doinga secondcut, mow acrossor peq:x.=r_licular to the firstcutpath. • Change your cuttingpatternfromweek to week. Mow northto southone week then changeto eastto west the nextweek.
