To avoid engine 8 MOWINGTIPS MULCHING • Under certain conditions, such as very tall grass, it may be necessery to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving dumps of grass clippings. It may also be necessary to reduce ground speed and/or run the lawn mower over the area a second time. IMPORTANT: For best performance, keep mower housing free of built-up grass and trash. Clean UNDERSIDE OF MOWER MOWING'rIPS HOUSING after each use. 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 biedegrade quickly to provide nutrients for the lawn. Always mulch with your highest engine (blade) speed as this will provide the best reoutting action of the blades. • Avoid cutting your lawn when it iswet. Wet grass tends to form clumps and interferes with the mulching action. The best time to mow your lawn _the early aftemoon. At this time the grass has dried and the newly cut area will not be exposed to the direct • 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. • 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. 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.

Make sure air filter and carburetor are up. • Use a wood block between blade and mower housing to prevent blade from turning when removing blade bolt. • Protect your hands with gloves and/or wrap blade with heavy cloth. • Remove blade bolt by turning counterclockwise. • Remove blade and attaching hardware (bolt, lock washer and hardened washer). NOTE: Remove the blade adapter and check the key inside hub of blade adapter. The key must be in good condition to work properly. Replace adapter if damaged. TO REPLACE BLADE • Position the blade adapter on the engine crankshaft. Be sure key in adapter and crankshaft keyway are aligned. • Position blade on the blade adapter aligning the two (2) holes in the blade with the raised lugs on the adapter. • Be sure the trailing edge of blade (opposite sharp edge) is up toward the engine. • Install the blade bolt with the lock washer and hardened washer into blade adapter and crankshaft. • Use block of wood between blade and lawn mower housing and tighten the blade bolt, turning clockwise. • The recommended tightening torque is 35-40 ft. Ibs. IMPORTANT: Blade bolt is grade 8 heat treated. 11 TO SHARPEN NOTE: BLADE We do not recommend sharpening blade - but if you do, be sure the blade is balanced. Care should be taken to keep the blade balanced. An unbalanced blade will cause eventual damage to lawn mower or engine. • The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower. • To check blade balance, drive a nail into a beam or wall. Leave about one inch of the straight nail exposed. Place center hole of blade over the head of the nail. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced. Crank shaft Blad_ keyway Blade 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 five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level.

HANDLE ENGINE CARBURETOR Your carburetor has a non-adjustable fixed main jet for mixture control. If your engine does not operate properly due to suspected carburetor problems, take your lawn mower to an authorized service center for repair or adjustment. IMPORTANT: Never tamper with the engine governor, which is factory set for proper engine speed. Overepeeding the engine above the factory high speed setting can be dangerous, if you think the engine-governed high speed needs adjusting, contact your nearest authorized service center, which has proper equipment and experience to make any necessary adjustments. ENGINE SPEED Your engine speed has been factory set. Do not attempt to increase engine speed or it may result in personal injury. If you believe that the engine is running too fast or too slow, take your lawn mower to an authorized service center for repair and adjustment. IMPORTANT: When folding the handle for storage or transportation, be sure to fold the handle as shown or you may damage the control cables. • When setting up your handle from the storage position, the lower handle will automatically lock into the mowing position. Operator Presence Control Bar _ Upper _'/_ Handle ----'-_ Fold Forward _ ---_.'..:.:: For Storage __ Mowing Position Lower Handle You can fold your lawn mower handle for storage. • Squeeze the bottom ends of the lower handle toward each other until the lower handle dears the handle bracket, then move handle forward. handle Handle bracket • Loosen upper handle mounting bolts enough to allow upper handle to be folded back. Squeeze to fold 14 ENGINE OIL ENGINE FUEL SYSTEM IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor, fuel filter, fuel hose, or tank during storage. 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 fuel 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 storage. 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. Drain oil (with engine warm! and replace with clean engine oil. (See ENGINE' in the Maintenance section of this manual). CYLINDER • Remove spark plug. o Pour one ounce (29 ml) 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. • If 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 allows condensation to form and will cause your unit to rust. IMPORTANT: Never cover mower while engine and exhaust areas are still warm. ACAUTION: Never store the lawn mower with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure.
