Fill to full line on dipstick, • 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 NOTE: Before filling fuel tank, remove and discard the debris plug that is inside the tank. • 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. _I_WARNING: Experience indicates that alcohol blended fuels (called gasehoi 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 ran until the fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instructionsfor additional information. Never use engine or carburetor cleaner productsin the fuel tank or permanent damage may occur. A CAUTION: Fill to bottom of gas tank filler ned<. Do not overf_l. Wipe off any spilled oil or fuel.

Engine holds 20 oz. of oil. For type and grade of oil to use, see "ENGINE" in Maintenance section of this manual. 1. Be sure lawnmower is level and area around oil fill is clean. 2. Remove engine oil cap and fill to the fur| line on the dipstick. Pour oil slowly. Do not over fill. 8 / Engineoil cap TO_TART ENGINE NOTE: Due to protectivecoatings on the engine, a small amount of smoke may be present during the initial use of the product and should be considered normal. 1. 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 far a few minutes. 2. 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 • To stop engine, release operator presence control bar, NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather over pdming 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. MOWlNGTIPS • 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 fawn mower over the area a second time. • For extremely heavy cutting, reduce the width of cut by ovedapp'mgpreviously cut path and mow slowly. • For better grass bagging and most cutting conditions, the engine speed should be set in the fast p(_ition. • 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 the 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 recutUng 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 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 the front. • 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 pattern 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.
