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. Engine oil cap w/ Gasoline filler cap To engage drive Drive control control desengaged BEFORE STARTING ENGINE OIL Your lawn mower is shipped without oil in the en . ⢠Be sure mower is level and area around oil fili is clean. ⢠Remove engine oil cap w/dipstick and fill to the full line on the dipstick. ⢠Use2 Jzs.of oil. Fortypeandgradaofoil to use, s^_. =ENGINE" in Maintenance section of this manual. ⢠Pour oH slowly. Do not over fill. ⢠Check oil level before each use. Add oil if needed. Fill to full _. ⢠To read proper level, tighten engine oil cap each time. ⢠Reinstall engine oil cap and tighten. ⢠Change the oil after every 25 hours of operaUon or each season. You may need to change the oil more often under dusty, dirty conditions. TO START ENGINE ⢠To stert a cold engine, push primer five (5) times before Wing to start. Use afirm push. This step is not usuagy necessary when sterting 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 beck. ⢠To stop engine, release operator presence control bar. NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather over pdming 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 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 (push- ing 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. 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 spacial mulching blade will recutthe grass clippings many limes and reduce them in size so that as they fail onto the lawn they will disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quicldy to pro_de nutrients for the lawn. Always mulch with your highest engine (blade) speed as this will provide the best recutting action of the blades. ⢠Avoid curling your lawn when it is wet. Wet grass tends to form dumps and interferes with the mulching action. The best time to mow your lawn is the Party afternoon. At this time the grass has dried and the newly cut area will not be exposed to the direct sun. ⢠For best results, adjust the lawn mower cutting height so that the lawn mower cuts off 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 slewly. ⢠Certain typas of grass and grass conditions may require that an area be mulched a seceed tJrne to complately hide the cl'q0pings. Whan doing a second cut, mow across or perpendicular to the first cut path. ⢠Change your curling pattern from week to week. Mow north to south one week then change to east to west the next week. This w_ll help prevent matting and graining of the lawn. /3 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, HOW TO USE YOUR LAWN MOWER CAUTION: Do not run your lawn mower without mulcher plate in place and door closed or without an approved clipping deflector or grasscatcher in place. Never attempt to operate the lawn mower with the rear door removed or propped open. ENGINE SPEED The engine speed was set at the factory for optimum performance. Speed is not adjustable. ENGINE ZONE CONTROL CAUTION: 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 laver-toward wheel, Move wheel up or down to suit your requirements. Be sure all wheels are in the same_et'_. 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.

DRIVE CONTROL ⢠Seif-propelling is controlled by hold!ng the operator presence control bar down to the handle and pushing the drive control lever forward until it clicks; then release the lever. ⢠Forward motion will stop when the operator presence control bar is released. To stop forward motion without stopping engine, release the operator presence control bar slightly until the drive control disengages. Hold operator presence control bar down to handle to continue mowing without self- propelling. ⢠To keep drive control engaged when turning comers, push down on handle and lift front wheels off ground while tuming lawn mower. Operator presence control bar Drive "_ control ADD GASOI.INE ⢠Fdl fuel tank. Use fresh, dean, regular unleaded gasoline with a minimum of 87 octane. Do not mix oli with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. WARNING: Expedence indk:atesthat alcohol blended fuels (called gasohol or using or methanol) can attract moisture which leads to separation and formation of acids dudng storage. Acidic gas can damage the fuel system of an engine while in storage. To avo'_l 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. Engine oil cap w/ Gasoline filler cap To engage drive Drive control control desengaged BEFORE STARTING ENGINE OIL Your lawn mower is shipped without oil in the en . ⢠Be sure mower is level and area around oil fili is clean. ⢠Remove engine oil cap w/dipstick and fill to the full line on the dipstick. ⢠Use2 Jzs.of oil. Fortypeandgradaofoil to use, s^_. =ENGINE" in Maintenance section of this manual. ⢠Pour oH slowly. Do not over fill. ⢠Check oil level before each use. Add oil if needed. Fill to full _. ⢠To read proper level, tighten engine oil cap each time. ⢠Reinstall engine oil cap and tighten. ⢠Change the oil after every 25 hours of operaUon or each season. You may need to change the oil more often under dusty, dirty conditions. TO START ENGINE ⢠To stert a cold engine, push primer five (5) times before Wing to start. Use afirm push. This step is not usuagy necessary when sterting 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 beck. ⢠To stop engine, release operator presence control bar. NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather over pdming 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 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 (push- ing 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. 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 spacial mulching blade will recutthe grass clippings many limes and reduce them in size so that as they fail onto the lawn they will disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quicldy to pro_de nutrients for the lawn. Always mulch with your highest engine (blade) speed as this will provide the best recutting action of the blades. ⢠Avoid curling your lawn when it is wet. Wet grass tends to form dumps and interferes with the mulching action. The best time to mow your lawn is the Party afternoon. At this time the grass has dried and the newly cut area will not be exposed to the direct sun. ⢠For best results, adjust the lawn mower cutting height so that the lawn mower cuts off 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 slewly. ⢠Certain typas of grass and grass conditions may require that an area be mulched a seceed tJrne to complately hide the cl'q0pings. Whan doing a second cut, mow across or perpendicular to the first cut path. ⢠Change your curling pattern from week to week. Mow north to south one week then change to east to west the next week. This w_ll help prevent matting and graining of the lawn. /3 9
