Engine oil cap Gasoline filler cap Operator presence control bar \ To engage drive control _ O.ve control Drive control disengaged BEFORE STARTING ENGINE 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 dipstick 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 overfill. • 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. TO START ENGINE 8 • To start a cold engine, push primer three (3) 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. • Turn electric start key clockwise to crank engine. IMPORTANT: Do not crank engine more not crank engine more than five continous seconds between eack time you try to start. Wait 5 to 10 seconds between each attempt. • To start engine using the auxiliary starter handle, follow the steps above. Exchange the use of the start key for starter handle. Pull starter handle quickly. Do not allow starter rope to snap back. • To stop engine, release operator MULCHING MOWING TIPS 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. MOWING TIPS IMPORTANT: Forbest performance, keep mower housing free of built-up grass and trash. See "Cleaning" in Maintenance section of this manual. • 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. The special mulching blade will recut the grass clippings many times and reduce them in size so that as they fal! 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. Max 1/3 9 F'LL 'N DATES ./'__d ASYOUCOMPLETE REGULAR SERVICE .....
