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 dil_tick. ⢠To read proper level, tighten engine oil cap each {ime. ⢠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. GAS ⢠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. 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 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 fuel tank, start the engine and let it run until fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instructions for additional information. Never use engine or carbure- tor cleaner products in fuel tank or permanent damage may occur. Engine oil cap Gasoline _ filler cap TO START ENGINE ⢠To start a cold engine, push primer five (5) times before trying to starL 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 weether 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 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. Clean UNDERSIDE OF MOWER HOUSING after each use. See "Cleaning" in MAINTENANCE section of this manual. ⢠The special 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 dumps 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, mow slowly and raise the rear of the lawn mower one wheel adjuster setting higher than the front. ⢠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 pettem from week 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. 9

An unbalanced blade will cause =.ventual damage to lawn mower or .=ngine. , 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 Crank shaft adapter 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 not turn freely, contact your nearest authorized service center. 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 1 Grease, Part No. 750369. Do not substitute. Bolt Crank Lockwasher Hardened Blade shaft washer Trailing adapter edge GRASS CATCHER ⢠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. DRIVE WHEELS Check front drive wheels each time before 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. ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SF, SH or SG. Select the oirs SAE viscosity grade according to your expected operating temperature. SAE VISCOSrrY GRADES 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 opera- tion 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. 12
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 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 ⢠Loosen cover knob ⢠Swing cover down and remove from hinge ⢠Pull paper filter out of air cleaner body ⢠Clean aircleanercoverand body. ⢠Install a new peper filter. ⢠Reinstall cover to air cleaner body.

Always wear safety glasses or eye shields while operating your lawn mower or performing any adjust- ments or _alm. We recommend a wide vision safety mask over spectacles or standard safety glasses. HOW TO USE YOUR LAWN MOWER ENGINE SPEED CONTROL 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 behind the lawn mower handle to stad and operate the lawn mower. TO ADJUST CUTnNG 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 satUng. NOTE: Adjuster is properly pesitk)ned when plate tab inserts into hole in lever. Also, 9- position adjusters (if so equipped) allow lever to be positioned between the plate tabs.

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 dil_tick. ⢠To read proper level, tighten engine oil cap each {ime. ⢠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. GAS ⢠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. 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 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 fuel tank, start the engine and let it run until fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instructions for additional information. Never use engine or carbure- tor cleaner products in fuel tank or permanent damage may occur. Engine oil cap Gasoline _ filler cap TO START ENGINE ⢠To start a cold engine, push primer five (5) times before trying to starL 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 weether 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 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. Clean UNDERSIDE OF MOWER HOUSING after each use. See "Cleaning" in MAINTENANCE section of this manual. ⢠The special 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 dumps 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, mow slowly and raise the rear of the lawn mower one wheel adjuster setting higher than the front. ⢠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 pettem from week 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. 9

An unbalanced blade will cause =.ventual damage to lawn mower or .=ngine. , 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 Crank shaft adapter 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 not turn freely, contact your nearest authorized service center. 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 1 Grease, Part No. 750369. Do not substitute. Bolt Crank Lockwasher Hardened Blade shaft washer Trailing adapter edge GRASS CATCHER ⢠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. DRIVE WHEELS Check front drive wheels each time before 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. ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SF, SH or SG. Select the oirs SAE viscosity grade according to your expected operating temperature. SAE VISCOSrrY GRADES 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 opera- tion 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. 12
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 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 ⢠Loosen cover knob ⢠Swing cover down and remove from hinge ⢠Pull paper filter out of air cleaner body ⢠Clean aircleanercoverand body. ⢠Install a new peper filter. ⢠Reinstall cover to air cleaner body.
