OPERATION BEFORE STARTING ENGINE OiL (See Fig. 9) 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 w/dipstick and fill to the full line 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. 9) 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 stor- age of 30 days or longer. Drain the fuel tank, start the engine and let it run until fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instruc- tions for additional information. Never use engine or carburetor cleaner products in fuel tank or permanent damage may occur. 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. Move engine speed control lever to fast (@) position. 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, release operator 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. FILLER CAP ENGINE OIL CAP W/DIPSTICK FiG. 9 MOWING TIPS o o 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. 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 of grass. 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 moweroverthe area a second time. If a trail of grass clippin gs is left on the rig ht 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 wil! 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 let dry before using. 10
OPERATION MULCHING MOWING TIPS IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. 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. 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 onty the top one-third of the grass blades (See Fig. 10). 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 re- quire 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, MAX 1/3 FiG, 10 11

If catcher needs replacing, replace only with a manufacturer approved replacement catcher. Give the lawn mower model number when ordering. 13
CUSTOME RESPONS BILITIES ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SF or SG. Select the oil's SAE viscosity grade according to your expected operating temperature. SAE VISCOSITY GRADES °F -20° 0 _ 30 _ 32 ° 40 _ 60" 80" 100 ° TEMPERATURE RANGE ANTfCrPATED BEFORE NEXT OIL CHANGE 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 the first two hours of operation and every 25 hours thereafter 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. TO CHANGE ENGINE OIL (See Fig. 12) 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 and drain oil into a suitable container. Rock lawn mower back and forth to remove any oil trapped inside of engine. Wipe off any spilled oil on lawn mower and on side of engine. ⢠Fi!l engine with oit. Fiil only to the "FULL" line on the dipstick. DO NOT OVER FILL. , Replace engine oil cap. Reconnect spark plug wire to spark plug. AIR RLTER Your engine will not run properly and may be damaged by using a dirty air filter. Repiace tlTe air filter every year, more often if you mow in very dusty, dirty conditions. Do not wash air filter. TO CHANGE AiR FILTER (See Fig. 13) Remove the air filter by turning counterclockwise to the stop and pull away from collar. Remove filter from inside of cover. Clean the inside of the cover and the collar to remove any dirt accumulation. ⢠Insert new filter into cover. Put air filter cover and filter into collar aligning the tab with the slot.

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 fue! 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 a!lowthe stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer, ENGINE OiL Drain oil (with engine warm) and replace with clean engine oil.

Pull starter handle slowly a few times to distribute oil. Replace with new spark plug. BATTERY Disconnect the battery from the engine connector and charge battery 48 hours. 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 wilt 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. _r store the lawn _, _ tank inside a build- _A ing where fumes may reach an open ,in flame or spark.

OPERATION BEFORE STARTING ENGINE OiL (See Fig. 9) 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 w/dipstick and fill to the full line 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. 9) 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 stor- age of 30 days or longer. Drain the fuel tank, start the engine and let it run until fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instruc- tions for additional information. Never use engine or carburetor cleaner products in fuel tank or permanent damage may occur. 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. Move engine speed control lever to fast (@) position. 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, release operator 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. FILLER CAP ENGINE OIL CAP W/DIPSTICK FiG. 9 MOWING TIPS o o 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. 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 of grass. 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 moweroverthe area a second time. If a trail of grass clippin gs is left on the rig ht 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 wil! 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 let dry before using. 10
OPERATION MULCHING MOWING TIPS IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. 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. 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 onty the top one-third of the grass blades (See Fig. 10). 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 re- quire 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, MAX 1/3 FiG, 10 11

TIRES Keep tires free of gasoline, oil, or insect control chemi- cals which can harm rubber. o Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage. BLADE CARE For best results, mower blade must be kept sharp. Re- place bent or damaged blades. TO REMOVE BLADE (See Fig. 11) ⢠Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug. , Turn lawn mower on its side. 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 counter-clockwise. Use a 9/16" box or open-end wrench. 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 (See Fig. 11) Position the blade adapter on the engine crankshaft. Be sure key in adapter and crankshaft keyway are aligned. Position btade 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 !ockwasher 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. NOTE: We do not recommend sharpening blade- but if you do, be sure the blade is balanced. TO SHARPEN BLADE 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 checkblade balance, drive a nailinto 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, tf either end of the blade moves downward, sharpen the heavy end until the blade is balanced.

The gear case is filled with lubricant to the proper level at the factory. The only time the _ubricant needs attention is if service has been performed on the gear case. If lubricant is required, use only Texaco Starplex Pre- mium Grease, part no. 750369. Do not substitute. DR_VE 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. , Remove any trash or grass cuttings from inside the dust cover, pinion and/or drive wheel gear teeth. Put wheels back in place. If after cleaning, the drive wheels do not turn freely, contact your nearest service center. GRASS CATCHER o The grass catcher may be hosed with water, but must be dry when used. Check your grass catcher often for damage or deterio o ration, 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. 13
CUSTOME RESPONS BILITIES ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SF or SG. Select the oil's SAE viscosity grade according to your expected operating temperature. SAE VISCOSITY GRADES °F -20° 0 _ 30 _ 32 ° 40 _ 60" 80" 100 ° TEMPERATURE RANGE ANTfCrPATED BEFORE NEXT OIL CHANGE 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 the first two hours of operation and every 25 hours thereafter 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. TO CHANGE ENGINE OIL (See Fig. 12) 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 and drain oil into a suitable container. Rock lawn mower back and forth to remove any oil trapped inside of engine. Wipe off any spilled oil on lawn mower and on side of engine. ⢠Fi!l engine with oit. Fiil only to the "FULL" line on the dipstick. DO NOT OVER FILL. , Replace engine oil cap. Reconnect spark plug wire to spark plug. AIR RLTER Your engine will not run properly and may be damaged by using a dirty air filter. Repiace tlTe air filter every year, more often if you mow in very dusty, dirty conditions. Do not wash air filter. TO CHANGE AiR FILTER (See Fig. 13) Remove the air filter by turning counterclockwise to the stop and pull away from collar. Remove filter from inside of cover. Clean the inside of the cover and the collar to remove any dirt accumulation. ⢠Insert new filter into cover. Put air filter cover and filter into collar aligning the tab with the slot. Push in on cover and turn clockwise to tighten. CONTAINER RG. t2 TURN CLOCKWISE SLOT AIR FILTE TAB TURN CLOCKWISE TO TIGHTEN AIR FILTER COVER FIG. 13 MUFFLER Inspect and replace corroded muffler as it could create a fire hazard and/or damage. SPARK PLUG Change your spark plug each year to make your engine star[ easier and run better. Set spark plug gap at .030 inch. CLEANING IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN UNDERSIDE OF MOWER HOUSING AFTER EACH USE. ⢠Turn lawn mower on its side. Make sure air filter and carburetor are up. Clean the underside of your lawn mower by scraping to remove build-up of grass and trash. Clean engine often to keep trash from accumulating.

When setting up your handle from the storage position, the lower handle will automatically lock into the mowing position. LOWER HANDLE HANDLE BRACKET SQUEEZETO FOLD HAIRPIN COTTER OPERATOR PRESENCE CONTROL BAR UPPER HANDLE FOLD FORWARD FOR STORAGE FOLD BACKWARD MOWING POSITION 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 fue! 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 a!lowthe stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer, ENGINE OiL Drain oil (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 ml) of oil through spark plug hole into cylinder. Pull starter handle slowly a few times to distribute oil. Replace with new spark plug. BATTERY Disconnect the battery from the engine connector and charge battery 48 hours. 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 wilt 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. _r store the lawn _, _ tank inside a build- _A ing where fumes may reach an open ,in flame or spark.
