OPERATION BEFORE STARTING ENGINE OIL (See Fig. 11) A 20 oz. bottle of Pennzoil SAE 30 oil is included with your new lawn mower. Remove engine oil cap and fill to the FULL !ine on the dipstick. * Use 20 ozs. of oil For type and grade of oil to use, see "ENGINE" in Customer Responsibilities 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. o Reinstall engine oil cap and tighten. ° After the first two (2) hours of mowing, change the oil, and every 25 hours thereafter. You may need to change the oil more often under dusty, dirty conditions. GAS (See Fig. 11) , Fill gasoline tank with fresh, clean unleaded gasoline. DO NOT USE PREMIUM GASOLINE. BE CAREFUL NOT TO OVER FILL TANK. 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 for30 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. GA,_OLINE RLLER CAP ENGINE OIL CAP W/DiPSTICK FIG. 11 TO START 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. • Push engine speed control lever to HIGH (,_) posi- tion. • Hold operatorpresence 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 con- trol 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. 10
OP ATION 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 en- gine and leaving clumps of grass clippings. • For extremely heavy cutting, reduce the width of cut and raise the rear of the lawn mower housing one (1) wheel adjuster setting higher than the front for better discharge o_ grass. For better grass bagging and most cutting conditions, the engine speed should be set in the '"HIGH" (_) (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 grass clippings is left on the right side of a rear discharge lawn mower, mow in a clockwise direction with a small overlap to collect the clippings on the next pass. • Keep top of engine around starter clear and clean of grass clippings and chaff. This will help engine air flow and extend engine life. 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 catchers off with water and tet dry before using. MULCHING MOWING TIPS IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN AFTER EACH USE. SEE "CLEANING" IN CUSTOMER RESPONSIBILITIES SECTION OF THIS MANUAL. The special mulching blade will recut the grass clip- pings 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. FiG, 12 * 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 (See Fig. 12). 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, mow slowly and raise the rear of the lawn mower one wheel adjuster setting higher than the front. o 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. 11

STORAGE Immediately prepare your lawn mower for storage at the end of the season or if the unit wilt not be used for 30 days or more. LAWN MOWER When lawn mower is to be stored for a period of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a clean, dry area. , Clean entire lawn mower (See "CLEANING" in the Customer Responsibilities section of this manual). , Lubricate as shown in the Customer Responsibilities section of this manual. • Be sure that all nuts, bolts, screws, and pins are securely fastened.

ALSO, 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. • Drain the fue! tank. • Start the engine and let it run until the fuel lines and carburetor are empty. , Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. • Use fresh fuel next season. NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during stor- age. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer. ENGINE OiL Drain oii (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Customer Responsibilities section of this manual). CYLINDER • Remove spark plug. Pour one ounce (29 m!) of oil through spark plug hole into cylinder. • Pull starter handle slowly a few times to distribute oil. , Replace with new spark plug. OTHER • Do not store gasoline from one season to another. • Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems. • tf possible, store your unit indoors and cover it to give protection from dust and dirt. • Cover your unit with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot breathe which al!ows condensation to form and will cause your unit to rust. IMPORTANT: NEVER COVER MOWER WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM. CAUTION: Never store the lawn mower with gasoline in the tank inside a build- ing where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure. 17
