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 ENGINE SPEED CONTROL 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 TO ATTACH GRASS CATCHER • Close the flip lid. Flip 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. &,CAUTION: 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. Grass frame bracket 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 whdn emptying; it will cause unnecessary wear. • 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. 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. BEFORE 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. • Use 20 ozs. of oil. For type and grade of oil to use, see "ENGINE" in Maintenance section of this manual. Lower wheels for high cut Le_ver Raise wheels for low STARTING Plate tab cut • Pour oil slowly. Do not over fill. • Check oil level before each use. Add oil if needed. 6 • Reinstall engine oil plug 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. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). 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 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. TO START ENGINE • To starta coldengine,push primerfive(5) timesbeforetryingto start. Use a firm push. This step is not usuallynecessarywhen startingan enginewhich has alreadyrunfor a few minutes. • Holdoperatorpresence controlbar downto the handleand pullstarter handlequickly. Do not allow starter ropeto snapback. • To stopengine,release operatorpresence controlbar. 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. 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.

LUBRICATION GENERAL ) Wheel Lister RECOMMENDATIONS 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 periodicallyto 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, replace air filterelement 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 (Sea "LUBRICATION CHART"). CHART (_ Brake springe bracket (_) Rrea; door (_ Engine oil hinge andle bracket (_) Spray lubricant (_ SAE 30 Motor oil.Section.
