TO ATTACH • Reinstall engine oil cap end lighten. • Chenge 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 GRASS CATCHER • Liftthe rear door.of the lawn mower and place the grass catcher frame hooks into the slots of the rear door. • The grass catcher is secured to the lawn mower housing when the rear door is lowered onto the grass catcher frame. • Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum lof 87 8 octane. (Use of leaded gasoline will increase carbon and load oxide deposits and reduce valve I'Ve). 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 loads 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 addlti_, information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. Gasoline filler cap 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 pdming 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 • For mostcuttingconditionsand better baggingperformance,the enginespeed shouldbe set in the fast position. • Under certainconditions,such as when mowingvery tallgrass, raisethe mower heighton the firstcutto reduce pushing effort,to avoidoverheatingthe engine,and to avoid leavingclumpsof grass clippings. Make the second cut to the desired height. For extremely heaw cutting, reduce the width of cut. Pores in cloth grass catchers can become filled with dirt and dust with use and the catcher will collect less grass. To prevent this, regularly hose catcher off with water and lot dry before use. MULCHING MOWING TIPS IMPORTANT: For bestperfo_, keep mowerhousingfree of built-upgrass and trash. See "Cleaning"in MAINTENANCE sectionof this manual. • The specialmulchingblade willrecurthe grassclippingsmany times and reduce them in size so that as they fallonto the lawnthey willdisperseintothe grass and not be noticed. Also,the mulchedgrass will biodegrade quicklyto providenutrients for the lawn. Alwaysmulchwith your highest engine(blade) speed as this willprovidethe best recuttingactionof the blades. • Avoidcuttingyour lawn when itis weL Wet grasstendsto form clumpsand interferes withthe mulchingaction. The besttime to mow your lawnis the earlyaftemnon. At this time the grass has driedand the newly cut area willnot be exposed to the direct sun. • Forbest results,adjustthe lawn mower cuttingheightso thatthe lawn mower cuts offonlythe top one-thirdof the grass blades. Ifthe lawn is overgrownitwillbe necessary to raisethe heightof cutto reduce pushing effortand to keep from overloadingthe engineand leavingdumps of mulched grass. Forextremelyheavy mulching, reduceyourwidthof cutby overlapping previouslycutpath and mow slowly. • Certaintypesof grass and grassconditions may requirethat an area be mulcheda secondtime to completelyhidethe clippings.When doinga secondcut, mow acrossorpeqoendloularto the first cut path. • Change your cuttingpatternfrom week to week. Mow north to south one week than changeto eastto westthe nextweek. This will helppreventmattingand grainingofthe lawn.

CLEANING IMPORTAN'£: For best performance, keep mower housing free of built-up grass and trash. Clean underside of mower housing after each use. Container AIR FILTER Your engine will not run properly and may be damaged by using a dirty air filter. Replace the air fitter 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 air cleaner cover and body. • install a new paper fitter. • Reinstall cover to air cleaner body.
