BEFORE STARTING ENGINE ADD OIL Your lawnmower is shipped without oil in the engine. 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 full line on the dipstick. Pour oil slowly. Do not over fill. NOTE: Allow oil to settle down into engine for accurate reading. To read proper level, tighten engine oil cap, then remove it to read the dipstick. 3. Reinstall engine oil cap and tighten. ⢠Check oil level before each use. Add oil if needed. 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 gaso- line. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. _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 dudng storage. Acidic gas can damage the fuel system of an enginewhile 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. _1_ CAUTION: Fill to bottom of gas tank filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. Gasoline oil cap (Discard debds plug inside) TO START ENGINE NOTE: Due to protective coatings on the engine, a small amount of smoke may be present dudng the initial use of the product and should be considered normal. t. 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. 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 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. 8
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 ovedoading 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 flint cuts in a clockwise direction. ⢠Pores in cloth grass catchers can "become filled with dirt and dust with use end 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 MOWINGTIPS IMPORTANT: For best performance, keep mower housing free of built-up grass and trash. See "Cleaning" in MAINTENANCE section of this manua ⢠The special mulching blade will reel the grass clippings many times and reduce them in size so that as they f onto the lawn they will disperse into grass and not be noticed. Also, the mulched grass will biodegrade quic to provide nutdents for the lawn. Always mulch with your highest eng (blade) speed as this will provide th, best recurring action of the blades. ⢠Avoid cutting your lawn when it is w_ Wet grass tends to form clumps and interferes with the mulching action, " best time to mow your lawn is the e_ afternoon. At this time the grass has dried and the newly cut area will no1 exposed to the direct sun. ⢠For best results, adjust the lawn mo' cutting height so that the lawn mowq cuts off only the top one-third of the grass blades. If the lawn is overgrov will be necessary to raise the height cut to reduce pushing effort and to kq from overloading the engine and leaving clumps of mulched grass. F¢ extremely heavy mulching, reduce y width of cut by overlapping previous cut path and mow slowly. ⢠Certain types of grass and grass conditions may require that an area mulched a second time to completel hide the clippings. When doing a second cut, mow across or peq3end; lar to the first cut path. ⢠Change your cutting pattem from w( to week. Mow north to south one we then change to east to west the next week. This will help prevent matting and graining of the lawn. MAX 1_ 9

Through normal use it will wear. If catcher needs replacing, replace only with a manufac- turer approved replacement catcher. Give the lawn mower model number when ordedng. ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SF-SJ. Select the oirs SAE viscosity grade according to your expected operating temperature. NOTE: Although multi-viscosity oils (5W30, 10W30 Otc.) 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, TO CHANGE ENGINE OIL NOTE: Before tipping lawn mower to drain oil, drain fuel tank by running engine until fuel tank is empty. 1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug. 2. Remove engine oil cap; lay aside on a clean surface. 3. 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. 4. Wipe off any spilled oil on lawn mower and on side of engine. 5. Fill engine with oil. (See "Add Oil" in the Operacion section of this manual.) 6. Reconnect spark plug wire to spark plug. 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. TO CLEAN AIR FILTER 1. Loosen screw and tilt cover to remove. 2. Carefully remove cartridge. 3. Clean by gently tapping on a flat surface. If very dirty, replace cartridge. _kCAUTION: Petroleum solvents, such as kerosene, are not to be used to clean cartridge. They may cause deterioration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge. 4. Install cartridge, then replace cover making sure the tabs are aligned with the slots in the back plate. Fasten screw securely.

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 dudng 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. 1. Drain the fuel tank. 2. 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. ENGINE OIL Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Maintenance section of this manual). CYLINDER 1. Remove spark plug. 2. Pour one ounce (29 ml) of oil through spark plug hole into cylinder. 3. Pull starter handle slowly a few times to distribute oil. 4. 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 protec- tive cover that does not retain mois- ture. Do not use plastic. Plastic cannot breathe which allows condensation to form and will cause your unit to rust. IMPORTANT: Never cover mower while engone and exhaust areas are still warm. A CAUTION: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

BEFORE STARTING ENGINE ADD OIL Your lawnmower is shipped without oil in the engine. 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 full line on the dipstick. Pour oil slowly. Do not over fill. NOTE: Allow oil to settle down into engine for accurate reading. To read proper level, tighten engine oil cap, then remove it to read the dipstick. 3. Reinstall engine oil cap and tighten. ⢠Check oil level before each use. Add oil if needed. 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 gaso- line. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. _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 dudng storage. Acidic gas can damage the fuel system of an enginewhile 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. _1_ CAUTION: Fill to bottom of gas tank filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. Gasoline oil cap (Discard debds plug inside) TO START ENGINE NOTE: Due to protective coatings on the engine, a small amount of smoke may be present dudng the initial use of the product and should be considered normal. t. 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. 2.

If you do flood engine, wait a few minutes before attempting to start and do not repeat priming steps. 8
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 ovedoading 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 flint cuts in a clockwise direction. ⢠Pores in cloth grass catchers can "become filled with dirt and dust with use end 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 MOWINGTIPS IMPORTANT: For best performance, keep mower housing free of built-up grass and trash. See "Cleaning" in MAINTENANCE section of this manua ⢠The special mulching blade will reel the grass clippings many times and reduce them in size so that as they f onto the lawn they will disperse into grass and not be noticed. Also, the mulched grass will biodegrade quic to provide nutdents for the lawn. Always mulch with your highest eng (blade) speed as this will provide th, best recurring action of the blades. ⢠Avoid cutting your lawn when it is w_ Wet grass tends to form clumps and interferes with the mulching action, " best time to mow your lawn is the e_ afternoon. At this time the grass has dried and the newly cut area will no1 exposed to the direct sun. ⢠For best results, adjust the lawn mo' cutting height so that the lawn mowq cuts off only the top one-third of the grass blades. If the lawn is overgrov will be necessary to raise the height cut to reduce pushing effort and to kq from overloading the engine and leaving clumps of mulched grass. F¢ extremely heavy mulching, reduce y width of cut by overlapping previous cut path and mow slowly. ⢠Certain types of grass and grass conditions may require that an area mulched a second time to completel hide the clippings. When doing a second cut, mow across or peq3end; lar to the first cut path. ⢠Change your cutting pattem from w( to week. Mow north to south one we then change to east to west the next week. This will help prevent matting and graining of the lawn. MAX 1_ 9

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 adiustments will need to be made periodically to properly maintain your unit. All adjustments in the Service and Adjustments section of this manual should be checked at least once each season. ⢠Once a year, replace the spark plug, clean or replace air filter element and check blade for wear. A new spark plug and clean/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 1. Check engine oil level. 2. Check for loose fasteners. LUBRICATION Keep unit well lubricated (Sea "LUBRI- CATION CHART"). LUBRICATION CHART (_Wheel adjuster \ o, spring bracket (_Handle bracket mounting pin (_) Refer to maintenance "Engine" section. _) Spray lubricant IMPORTANT: Do not oil or grease plastic wheel bearings, viscous lubri- cants 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. 10

TIRES ⢠Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber. ⢠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. Replace bent or damaged blades. TO REMOVE BLADE 1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug. 2. Turn lawn mower on its side. Make sure air filter and carburetor are up. 3. Use a wood block between blade and mower housing to prevent blade from turning when removing blade bolt. NOTE: Protect your hands with gloves and/or wrap blade with heavy cloth. 4. Remove blade bolt by tuming counter- clockwise. 5. Remove blade and attaching hard- ware (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 condi- tion to work properly. Replace adapter if damaged. TO REPLACE BLADE 1. Position the blade adapter on the engine crankshaft. Be sure key in adapter and crankshaft keyway are aligned. 2. Position blade on the blade adapter aligning the two (2) holes in the blade with the raised lugs on the adapter. 3. Be sure the trailing edge of blade (opposite sharp edge) is up toward the engine. 4. Install the blade bolt with the lock washer and hardened washer into blade adapter and crankshaft. 5. Use block of wood between blade and lawn mower housing and tighten the blade bolt, tuming clockwise. ⢠The recommended tightening torque is 35-40 ft. Ibs. IMPORTANT: Blade bolt is grade 8 heat treated. TO SHARPEN BLADE NOTE: We do not recommend sharpen- ing 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 gdnding wheel. Do not attempt to sharpen while on the mower. ⢠To check blade balance, ddve 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. 11

Through normal use it will wear. If catcher needs replacing, replace only with a manufac- turer approved replacement catcher. Give the lawn mower model number when ordedng. ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SF-SJ. Select the oirs SAE viscosity grade according to your expected operating temperature. NOTE: Although multi-viscosity oils (5W30, 10W30 Otc.) 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, TO CHANGE ENGINE OIL NOTE: Before tipping lawn mower to drain oil, drain fuel tank by running engine until fuel tank is empty. 1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug. 2. Remove engine oil cap; lay aside on a clean surface. 3. 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. 4. Wipe off any spilled oil on lawn mower and on side of engine. 5. Fill engine with oil. (See "Add Oil" in the Operacion section of this manual.) 6. Reconnect spark plug wire to spark plug. 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. TO CLEAN AIR FILTER 1. Loosen screw and tilt cover to remove. 2. Carefully remove cartridge. 3. Clean by gently tapping on a flat surface. If very dirty, replace cartridge. _kCAUTION: Petroleum solvents, such as kerosene, are not to be used to clean cartridge. They may cause deterioration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge. 4. Install cartridge, then replace cover making sure the tabs are aligned with the slots in the back plate. Fasten screw securely.

Catcher frame handle Frame opening 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 the engine is running too fast or too slow, take your lawn mower to an authorized 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 propedy 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 proper engine speed. Overspeeding the engine above the factory high speed setting can be dangerous. If you think the engine-governed high speed needs adjusting, contact your nearest autho- rized 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, 1. Clean entire lawn mower (See "CLEANING" in the Maintenance section of this manual). 2. Lubdcate as shown in the Mainte- nance section of this manual. 3. Be sure that all nuts, bolts, screws, and pins are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary. 4.

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 dudng 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. 1. Drain the fuel tank. 2. 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. ENGINE OIL Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Maintenance section of this manual). CYLINDER 1. Remove spark plug. 2. Pour one ounce (29 ml) of oil through spark plug hole into cylinder. 3. Pull starter handle slowly a few times to distribute oil. 4. 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 protec- tive cover that does not retain mois- ture. Do not use plastic. Plastic cannot breathe which allows condensation to form and will cause your unit to rust. IMPORTANT: Never cover mower while engone and exhaust areas are still warm. A CAUTION: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
