The operation of any lawn mower can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your lawn mower or performing any adjust- merits or repairs. We recommend a wide vision safety mask over spectacles or standard safety glasses. HOW TO USE YOUR LAWN MOWER ENGINE SPEED The engine speed was set at the factory for optimum performance. Speed is not adjust- able. ENGINE ZONE CONTROL CAUTION: Federal regulations require an engine sentrol to be inst_ed on this lawn mower in order to minimize the risk of blade contact injury. Do not under any circumstances attempt to defeat the function of the operator control. The blade turns when the engine is running. ⢠Your lawn mower is equ'_l:_:l with an operator presence control bar which requires the operetor to be positioned behind the lawn mower handle to start and operate the lawn mower. TO ADJUST CUTTING HEIGHT ⢠Raise wheels for low cut and lower wheels for high cut. ⢠Adjust cutting height to suit your require- ments. Medium position is best for most lawns. ⢠To change cutting height, squeeze adjuster lever toward wheel. Move wheel up or down to suit your requirements. Be sure all wheels are in the same setting. NOTE: Adjuster is properly positioned when plate tab inserts into hole in lever. Also, 9- position adjusters (if so equipped) allow lever to be positioned between the plate tabs. Raise wheels for low cut Lower wheels for high cut Plate tab 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 dean. â¢Rernove engine oil p/ug and flu to the top of slot in filler hole. ⢠Use 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 overfill ⢠Check oil level before each use. Add oil if needed. ⢠Reinsta_ engine oil plug and tighten. ⢠Change the oil after every 25 hours of eperation or each seeson. You moy need to change the oil more often under dusty, dirty conditions. GAS ⢠Fill fuel tank. Use fresh, dean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline wil increase carbon and lead oxide deposits and reduce valve rife). Do not mix on with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW 32°F(0°C), use fresh, clean winter grade gasoline to help insure good cold weather starting. WARNING: Experience indicates that alcohol b/ended fueis (called gesohoi or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acicfic 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. CAUTION: Fill to bottom of gas tank filler neck. DO not overfill. Wipe off any spilled oil or fuel. Do net store, spill or use gasoline near an open flame. Gasoline filler cap Oil filler plug 6
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. ⢠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 ⢠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 t ° 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. 7

GENERALRECOMMENDATIONS 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 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 ⢠Check engine oil level. ⢠Check for loose fasteners. LUBRICATION Keep unit well lubricated (See "LUBRICA- TION CHART"). LUBRICATION CHART Wheel adjuster (_ Engine oil (_ Brake spring (_ Discharge bracket guard (_ Handle bracket hinge pin mounting pin (_ Spray lubricant (_ Refer to MAINTENANCE"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, powered graphite type lubricant sparingly.

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. ENGINE OIL Drain oil (with engine warm) and replace with clean engine oil. (See"ENGINE" inthe 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 d'_ribute 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 r_in moisture. Do not use plastic. Plastic cannot breathe which ailews condensation to form and will cause your unit to rust. IMPORTANT: Never cover mower whi_e engine and exhaust areas are still warm. 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.

The operation of any lawn mower can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your lawn mower or performing any adjust- merits or repairs. We recommend a wide vision safety mask over spectacles or standard safety glasses. HOW TO USE YOUR LAWN MOWER ENGINE SPEED The engine speed was set at the factory for optimum performance. Speed is not adjust- able. ENGINE ZONE CONTROL CAUTION: Federal regulations require an engine sentrol to be inst_ed on this lawn mower in order to minimize the risk of blade contact injury. Do not under any circumstances attempt to defeat the function of the operator control. The blade turns when the engine is running. ⢠Your lawn mower is equ'_l:_:l with an operator presence control bar which requires the operetor to be positioned behind the lawn mower handle to start and operate the lawn mower. TO ADJUST CUTTING HEIGHT ⢠Raise wheels for low cut and lower wheels for high cut. ⢠Adjust cutting height to suit your require- ments. Medium position is best for most lawns. ⢠To change cutting height, squeeze adjuster lever toward wheel. Move wheel up or down to suit your requirements. Be sure all wheels are in the same setting. NOTE: Adjuster is properly positioned when plate tab inserts into hole in lever. Also, 9- position adjusters (if so equipped) allow lever to be positioned between the plate tabs. Raise wheels for low cut Lower wheels for high cut Plate tab 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 dean. â¢Rernove engine oil p/ug and flu to the top of slot in filler hole. ⢠Use 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 overfill ⢠Check oil level before each use. Add oil if needed. ⢠Reinsta_ engine oil plug and tighten. ⢠Change the oil after every 25 hours of eperation or each seeson. You moy need to change the oil more often under dusty, dirty conditions. GAS ⢠Fill fuel tank. Use fresh, dean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline wil increase carbon and lead oxide deposits and reduce valve rife). Do not mix on with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW 32°F(0°C), use fresh, clean winter grade gasoline to help insure good cold weather starting. WARNING: Experience indicates that alcohol b/ended fueis (called gesohoi or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acicfic 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. CAUTION: Fill to bottom of gas tank filler neck. DO not overfill. Wipe off any spilled oil or fuel. Do net store, spill or use gasoline near an open flame. Gasoline filler cap Oil filler plug 6
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. ⢠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 ⢠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 t ° 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. 7

GENERALRECOMMENDATIONS 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 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 ⢠Check engine oil level. ⢠Check for loose fasteners. LUBRICATION Keep unit well lubricated (See "LUBRICA- TION CHART"). LUBRICATION CHART Wheel adjuster (_ Engine oil (_ Brake spring (_ Discharge bracket guard (_ Handle bracket hinge pin mounting pin (_ Spray lubricant (_ Refer to MAINTENANCE"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, powered graphite type lubricant sparingly.

TIRES ⢠Keep tiros 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 ⢠Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug. ⢠Tum 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 tuming 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 ⢠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, 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 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 Crankshaft adapter'P'-_ keyway Key Crank- shaft bolt Lock Blade washer edge adapter Hardened washer GRASS CATCHER (If purchased as an accesssory) ⢠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 manufac- turer approved replacement catcher. Give the lawn mower model number when ordering. ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SF, SG or SH. Select the oirs SAE viscosity grade according to your expected operating temperature. SAE VISGOS_TY GRADES -26* ._o- 6- lO- 20- 30- TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starling 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 ff=e oil after every 25 hours of operatlen 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 13ghten oil plug securely each time you check the oil level. TO CHANGE ENGINE OIL ⢠Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug. ⢠Be sure lawn mower is on level surface. ⢠Oil will drain more freely when warm. ⢠Catch oil in a suitable container. ⢠Remove bottom oil drain plug. ⢠After oil has drained completely, replace oil drain plug and tighten securely. ⢠Refill engine with oil.

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, keep mower housing free of built-up 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 scraping 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 are covered to keep water out. Water in engine can result in shortened engine life. CAUTION: BEFORE PERFORMINGANY SERVICE OR ADJUSTMENTS: ⢠Release control bar. ⢠Make sure the blade and all moving parts have completely stopped. ⢠Disconnect spark plug wire from spark plug and place where it cannot come in contact with plug.

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. ENGINE OIL Drain oil (with engine warm) and replace with clean engine oil. (See"ENGINE" inthe 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 d'_ribute 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 r_in moisture. Do not use plastic. Plastic cannot breathe which ailews condensation to form and will cause your unit to rust. IMPORTANT: Never cover mower whi_e engine and exhaust areas are still warm. 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.
