NOTE: Allow oil to settle down into engine for accurate dipstick reading. • Engine holds 27 ozs. of oil. Fortype 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 ellen under dusty, dirty conditions. Engine oil cap TO START ENGINE • To start a cold engine, push primer three (3) times before trying to starL 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.

In warmer weather over priming may caus, 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. 8 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. MULCHING MOWING TIPS 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 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 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 weekto 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. th_4_'l_i?:,_f'l:;_'-'} 9 Max 1/3 MA,.TENANCESC.EOULE " F,LL,.

Through normal use it will wear. If catcher needs replacing, replace only with a manufacturer approved replacement catcher. Give the lawn mower model number when ordering. DRIVE WHEELS Check front drive wheels each time before you mow to be sure they move freely. The wheels not turning freely means trash, grass cuttings, etc. are in the drive wheel area and must be cleaned to free drive wheels. If necessary to clean the drive wheels, check both front wheels. • Remove hubcaps, hairpin cotters and washers. • Remove wheels from wheel adjusters. 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. Check the crankcase oil level before starting the engine and after each live (,= hours of continuous use. Tighten oil plu(. securely each time you check the oil level. 12 TO CHANGE ENGINE OIL NOTE: Before tipping lawn mower to drain oil, drain fuel tank by running engine until fuel tank is empty. • Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug. • Remove engine oil cap; lay aside on a clean surface. • Tip lawn mower on its side as shown and drain oil into a suitable container.
