TO ADJUST CUTTING HEIGHT • Raise wheels for low cut and lower wheels for high cut. • Adjust cutting height to suit your requirements. 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. empty. Use fresh fuel next season. See Storage Instructionsfor additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. NOTE: Adjuster is properly positioned when plate tab inserts into hole in lever. Also, 9position adjusters (if so equipped) allow lever tobe positioned betweentheplatetabs. 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. Raise wheels for low cut Lower wheels for high cut • Fill fuel tank. Use fresh, dean, regular unleaded gasoline with a minimum of 87 octane. (Useof 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 Gasoline filler cap Plate tab BEFORE STARTING ENGINE OIL Oil filler plug Your lawn mower is shipped without oil in the engine. • Be sure mower is level and area around oil fillis dean. 6 TO START ENGINE MOWING • 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. • 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. TIPS • 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. 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. • 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 s .v,c Chec_ for Loose Fasteners Clean/Inspect Grass Catcher DA"rES i _/im Is/ I I_ M CleanLawnMower O (Power-Propelled Clean Under DriveMowem) Cover q/ Ched_ drive belt/pulleys S (Power-Propelled Mowers) I/ CheddShame_tReplace Blade Lubrication Chad _1_, 3 Clean Battery/Recharge IB o Mow1 V' E CheckEngineOil Level N ChangeEngineOil G Clean Air Filter I V' !,/1,2 Ii/ Inspect Muffler 2 _/ N aean or ReplaceSparkPlug v E Replace AirFilterPaperCartridge I/2 t - Changemoreoftenwhenopera,rigundera heavyloador inhighambie_tempera_ 2 - S_,_e mo_o_m wh*moperaingin dktyor dustyconditions. 3.

GENERALRECOMMENDATIONS LUBRICATION CHART Wheel adjuster (_ Engine oil 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 "LUBRICATION CHART"). (_ Discharge guard (_ Handle bracket mounting pin Brake spring bracket hinge 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.
