We recommend a wide vision safety mask over spectacles or standard safety glasses. HOWTO USEYOUR LAWN MOWER ENGINE SPEED The engine speed was set at the factory for optimum performance. Speed is not adjustable. ENGINE ZONE CONTROL ACAUTION: Federal regulations require an engine control to be installed 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 equipped with an operator presence control bar which requires the operator 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.

Lift top lid must be closed while operating lawn mower. ⢠Lift the rear door on the mower housing and place the grass catcher frame onto the formed tabs on the rear door hinge bracket. ⢠The grass catcher is secured to the lawn mower housing when the rear door is lowered onto the grass catcher frame. ACAUTION: Do not run your lawn mower without clipping deflector or approved grass catcher in place. Never attempt to operate the lawn mower with the rear door removed or propped open. Hinge Rear door Grass catcher frame Formed tabs TO EMPTY GRASS CATCHER ⢠To remove grass catcher, release operator presence control bar to stop engine. ⢠Lift up rear door and remove the grass catcher by the handle. NOTE: Do not drag the bag when emptying; it will cause unnecessary wear. 7
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 plug and fill to the top of slot in filler hole. NOTE: Allow oil to settle down into engine for accurate 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. ⢠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. Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. AWARNING: 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 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. ACAUTION: 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 filler cap Engine oil plug 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. 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 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. ⢠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 mower over the area a second time. ⢠If a trail of clippings is left on the right side of a rear discharge mower, mow in a clockwise direction with a small overlap to collect the clippings on the next pass. ⢠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. 9

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 adjustments or repairs. We recommend a wide vision safety mask over spectacles or standard safety glasses. HOWTO USEYOUR LAWN MOWER ENGINE SPEED The engine speed was set at the factory for optimum performance. Speed is not adjustable. ENGINE ZONE CONTROL ACAUTION: Federal regulations require an engine control to be installed 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 equipped with an operator presence control bar which requires the operator 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.

ACAUTION: Do not run your lawn mower without clipping deflector or approved grass catcher in place. Never attempt to operate the lawn mower with the rear door removed or propped open. Hinge Rear door Grass catcher frame Formed tabs TO EMPTY GRASS CATCHER ⢠To remove grass catcher, release operator presence control bar to stop engine. ⢠Lift up rear door and remove the grass catcher by the handle. NOTE: Do not drag the bag when emptying; it will cause unnecessary wear. 7
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 plug and fill to the top of slot in filler hole. NOTE: Allow oil to settle down into engine for accurate 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. ⢠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. Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. AWARNING: 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 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. ACAUTION: 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 filler cap Engine oil plug 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. 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 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. ⢠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 mower over the area a second time. ⢠If a trail of clippings is left on the right side of a rear discharge mower, mow in a clockwise direction with a small overlap to collect the clippings on the next pass. ⢠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. 9

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, 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 (i) Wheel adjuster Engine oil \ \Brake spring bracket '"@Rear door hinge (_) Handle bracket 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, powdered graphite type lubricant sparingly. 10

LAWN MOWER Always observe safety rules when performing any maintenance. 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 ⢠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. ⢠Remove blade and attaching hardware (bolt, lock washer and hardened washer). NOTE: Remove the blade adapter and check the key inside hub of blade adapter. The key must be in good condition to work properly. Replace adapter if damaged. TO REPLACE BLADE ⢠Position the blade adapter on the engine crankshaft. Be sure key in adapter and crankshaft keyway are aligned. ⢠Position blade on the blade adapter aligning the two (2) holes in the blade with the raised lugs on the adapter. ⢠Be sure the trailing edge of blade (opposite sharp edge) is up toward the engine. ⢠Install the blade bolt with the lock washer and hardened washer into blade adapter and crankshaft. ⢠Use block of wood between blade and lawn mower housing and tighten the blade bolt, turning clockwise. ⢠The recommended tightening torque is 35-40 ft. Ibs. 11
IMPORTANT: Blade bolt is grade 8 heat treated. TO SHARPEN BLADE NOTE: We do not recommend sharpen- ing blade - but if you Uo, 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.

If catcher needs replacing, replace only with a manufacturer 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 oil's SAE viscosity grade according to your expected operating temperature. SAE VISCOSITY GRADES .20 = ⢠30" -20" -I0" o" 10" 20" 30" TEMPERATURE RANGE ANTICIPATED 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 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 ⢠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. Pour slowly. Do not over fill. ⢠Fill to top of slot inside of filler hole. ⢠Reconnect spark plug wire to spark plug. Drain 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. Do not wash air filter. TO CHANGE AIR FILTER ⢠Remove the air filter by turning counter- clockwise 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. Collar Trun counter clockwise to Clip tighten sl t Air filter Turn clockwise to Air filter cover remove 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, 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 do 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. 13
_,CAUTION: Before performing any service and adjustments: ⢠Release control bar and stop engine. ⢠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. LAWN MOWER TO ADJUST CUTTING HEIGHT See 'q-O ADJUST CUTTING HEIGHT" in the Operation section of this manual. REAR DEFLECTOR The rear deflector, attached between the rear wheels of your lawn mower, is provided to minimize the possibility that objects will be thrown out the rear of the lawn mower into the operator's mowing position. If the rear deflector becomes damaged, it should be replaced. TO ADJUST HANDLE The handle can be mounted in a high or low position. The mounting holes in the bottom of lower handle are off center for raising or lowering the handle. ⢠Remove upper handle and all parts attached to lower handle. ⢠Remove hairpin cotters from lower handle bracket mounting pin. ⢠Squeeze lower handle in to remove it from mounting pins. ⢠Turn lower handle over to raise or lower handle. ⢠Squeeze lower handle in and position holes onto mounting pins on handle bracket. ⢠Reassemble upper handle and all parts removed from lower handle.

Make sure the frame handle is outside of the bag top. ⢠Slip vinyl bindings over frame. NOTE: If vinyl bindings are too stiff, hold them in warm water for a few minutes. If bag gets wet, let it dry before using. ACAUTION:Do not run your lawn mower without clipping deflector or approved grass catcher in place. Never attempt to operate the lawn mower with the rear door removed or propped open. Catcher frame \ \ Rigid Bottom 14
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 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 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 authorzed service center, which has proper equipment and experience to make any necessary adjustments. 15
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, belts, 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 belts 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 any damage the control cables. ⢠When setting up your handle from the storage position, the lower handle will automatically lock into the mowing position. Lower handle Squeeze to fold Handle bracket Operator presence control bar \ Fold foward for sto_._iy _ Lower _l o handle v Upper handle /_',_ ,,S ) /41_'Fold _' "_ / backward I_ Mowing "_" position ENGINE FUELSYSTEM IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor, f 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. Hairpin co_er 4_
