Deflector ⢠_ Mulcher Door \ Bracket _:_CAUTION: Do not operate your lawn mower without mulcher door in closed position, discharge deflector in place, or approved grass catcher in place. 6
BEFORE STARTING ENGINE OIL 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 and fill to the full line on the dipstick. NOTE: Allow oil to settle down into engine for accurate dipstick reading. ⢠Engine holds 20 ozs. of oil. For type 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 often under dusty, dirty conditions. ADD GASOLINE ⢠Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. _cWhARNING; Experience indicates that ol blenood fueJs _calleo gasonol 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 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. f._,.,CAUTION: Fill to bosom of gas.tank iHer neck. Do not ovenill. Wipe on any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. TO START ENGINE ⢠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 for a few minutes. ⢠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. MOWING TIPS 7 ⢠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. ⢠For side discharge lawn mowers, cutting in a counter-clockwise direction, starting at the outside of the area to be cut, spreads grass clippings more evenly and puts less load on the engine. To keep clippings off of walkways, flower beds, etc., make the first cuts in a clockwise direction. ⢠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 speciaJ 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 pattern from weak 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. 8

TO SHARPEN BLADE NOTE: 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. Blade Key adapter Crankshaft keyway Blade Lockwasher Blade shaft bolt Hardened Trailing washer edge Blade adapter GRASS CATCHER (If purchased as an accessory) ⢠The grass catcher may be hosed with water, but must be dry when used. ⢠Check your grass catcher often for damage or deterioration. 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. GEAR CASE ⢠To keep your drive system working properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season. ⢠The gear case is filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case. ⢠If lubricant is required, use only Texaco Starplex Premium Grease, part no. 750369. Do not substitute. DRIVE WHEELS Check front drive wheels each time befon 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 no1 turn freely, contact your nearest authorized service center. ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SF, SG or SH. Selec the oil's SAE viscosity grade according to you expected operating temperature. SAE VISCOSITY GRADES -2O" 40" -20 = .10 _ o P 10" 20" 30" TEMPERATURE RANGE ANTICIPATED BEFORE NEXT O_L CHANGE NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils wil 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 orat 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. 11
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. 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. ⢠Fill engine with oil. Fill only to the "FULL" line on the dipstick. DO NOT OVER FILL. ⢠Replace engine oil cap. ⢠Reconnect spark plug wire to spark plug. Container AIR FILTER Your engine will not run properly and may be damaged by using a dirty air filter. Replace the air filter every year, more often if you mow in very dusty, dirty conditions. Do not wash air filter. TO CHANGE AIR FILTER ⢠Remove the air filter by turning clock- wise 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 counterclock- wise to tighten.

ENGINE 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 engine is running too fast or too slow, take your mower to an autho- rized service center for repair and adjustment. 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 and/or adjustment. IMPORTANT: Never tamper with the engine governor, which is factory set for the proper engine speed. Overspeeding the engine above the factory high speed scan 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. Immediately prepare your lawn mower for storage at the end of the season or if the unit will 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 "CLEAN- ING" in the Maintenance section of this manual). ⢠Lubricate as shown in the Maintenance section of this manual. ⢠Be sure that all nuts, bolts, screws, and pins are securely fastened.

ENGINE FUELSYSTEM 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. ENGINEOIL Drain oil (with engine warm) and replace with clean engine oil (See "ENGINE" in the Maintenance 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. 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 if 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. 15

TO INSTALL DISCHARGING DEFLECTOR ⢠Lift door upward on it's hinge until the deflector frame can be hooked over the door mounting bracket as shown. ⢠Release the door to rest against deflector frame. ⢠To return to mulching operation, reverse the above steps and be sure door is in closed position. Deflector ⢠_ Mulcher Door \ Bracket _:_CAUTION: Do not operate your lawn mower without mulcher door in closed position, discharge deflector in place, or approved grass catcher in place. 6
BEFORE STARTING ENGINE OIL 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 and fill to the full line on the dipstick. NOTE: Allow oil to settle down into engine for accurate dipstick reading. ⢠Engine holds 20 ozs. of oil. For type 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 often under dusty, dirty conditions. ADD GASOLINE ⢠Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. _cWhARNING; Experience indicates that ol blenood fueJs _calleo gasonol 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 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. f._,.,CAUTION: Fill to bosom of gas.tank iHer neck. Do not ovenill. Wipe on any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. TO START ENGINE ⢠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 for a few minutes. ⢠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. MOWING TIPS 7 ⢠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. ⢠For side discharge lawn mowers, cutting in a counter-clockwise direction, starting at the outside of the area to be cut, spreads grass clippings more evenly and puts less load on the engine. To keep clippings off of walkways, flower beds, etc., make the first cuts in a clockwise direction. ⢠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 speciaJ 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 pattern from weak 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. 8

GENERAL RECOMMENDATIONS The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain mower as instructed in this manual. Some adjustments will need to be made periodically to properly maintain your unit. All adjustments in the Service and Adjust- ments section of this manual should be chscked at least once each seascn. ⢠Once a year, replace the spark plug, clean or replace air filter element and check blade for wear. A new spark plug and dean/new air filter element assures proper air-fuel mixture and helps your engine run better and last longer. ⢠Follow the maintenance schedule in this manual. BEFORE EACH USE ⢠Check engine (xl level. ⢠Check for loose fasteners. LUBRICATION Keep unit well lubricated (See "LUBRICATION CHART"). LUBRICATION CHART _Wheel adjuster (DMulcher door _)Engine oil _)Brake spring bracket mounting pin _)Spray lubricante ¢DRefer to MAINTINANCE "ENGINE" SECTION. IMPORTANT: Do not oil or grease plastic wheel bearings. Viscous lubricants will attract dust and dirt that will shorten the life of the self lubricating bearings. If you feel they must be lubricated, use only a dry, powdered graphite type lubricant sparingly. 9

Ibs. IMPORTANT: Blade bolt is grade 8 heat treated. 10
TO SHARPEN BLADE NOTE: 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. Blade Key adapter Crankshaft keyway Blade Lockwasher Blade shaft bolt Hardened Trailing washer edge Blade adapter GRASS CATCHER (If purchased as an accessory) ⢠The grass catcher may be hosed with water, but must be dry when used. ⢠Check your grass catcher often for damage or deterioration. 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. GEAR CASE ⢠To keep your drive system working properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season. ⢠The gear case is filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case. ⢠If lubricant is required, use only Texaco Starplex Premium Grease, part no. 750369. Do not substitute. DRIVE WHEELS Check front drive wheels each time befon 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 no1 turn freely, contact your nearest authorized service center. ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SF, SG or SH. Selec the oil's SAE viscosity grade according to you expected operating temperature. SAE VISCOSITY GRADES -2O" 40" -20 = .10 _ o P 10" 20" 30" TEMPERATURE RANGE ANTICIPATED BEFORE NEXT O_L CHANGE NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils wil 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 orat 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. 11
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. 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. ⢠Fill engine with oil. Fill only to the "FULL" line on the dipstick. DO NOT OVER FILL. ⢠Replace engine oil cap. ⢠Reconnect spark plug wire to spark plug. Container AIR FILTER Your engine will not run properly and may be damaged by using a dirty air filter. Replace the air filter every year, more often if you mow in very dusty, dirty conditions. Do not wash air filter. TO CHANGE AIR FILTER ⢠Remove the air filter by turning clock- wise 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 counterclock- wise to tighten. Slot Air filter Turn d.ock_s_ to clockwise to Air filter cover tighten 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 start easier and run better. Set spark plug gap at .030 inch. CLEANING IMPORTANT: For best performance, kiip mower housing free of built-grass and trash. Clean the underside of your mower after each use. _CAUTION- Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with the spark plug. ⢠Turn lawn mower on its side. Make sure air filter and carburetor are up. Clean the underside of your lawn mower by scr_ing to remove build-up of grass and trash. ⢠Clean engine often to keep trash from accumulating. A clogged engine runs hotter and shortens engine life. ⢠Keep finished surfaces and wheels free of all gasoline, oil,etc. ⢠We de not recommend using a garden hose to clean lawn mower unless the electrical system, muffler, air filter and carburetor ere covered to keep water out. Water in engine can result in shortened engine life. CLEAN UNDER DRIVE COVER Clean under drive cover at least twice a season.

ENGINE 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 engine is running too fast or too slow, take your mower to an autho- rized service center for repair and adjustment. 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 and/or adjustment. IMPORTANT: Never tamper with the engine governor, which is factory set for the proper engine speed. Overspeeding the engine above the factory high speed scan 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. Immediately prepare your lawn mower for storage at the end of the season or if the unit will 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 "CLEAN- ING" in the Maintenance section of this manual). ⢠Lubricate as shown in the Maintenance section of this manual. ⢠Be sure that all nuts, bolts, screws, and pins are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary. ⢠Touch up all rusted or chipped paint surfaces; sand lightly before painting. 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 clears the handle bracket, then move handle forward. ⢠Loosen upper handle mounting bolts enough to allow upper handle to be folded back. 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.

ENGINE FUELSYSTEM 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. ENGINEOIL Drain oil (with engine warm) and replace with clean engine oil (See "ENGINE" in the Maintenance 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. 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 if 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. 15
