I. GENERAL OPERATION • Read, understand, and follow all instructions on the machine and in the manual(s) before starting. Be thoroughly familiar with the controls and the proper use of the machine before starting. • Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times. • Only allow responsible individuals, who are familiar with the instructions, to operate the machine. • Clear the area of objects such as rocks, toys, wire, bones, sticks, etc., which could be picked up and thrown by blade. • Be sure the area is clear of other people before mowing. Stop machine if anyone enters the area. • Do not operate the mower when barefoot or wearing open sandals. Always wear substantial foot wear. • Do not pull mower backwards unless absolutely necessary. Always look down and behind before and while moving backwards. • Never direct discharged material toward anyone. Avoid discharging material against a wall or obstruction. Material may richochet back toward the operator. Stop the blade when crossing gravel surfaces. • Do not operate the mower without proper guards, plates, grass catcher or other safety protective devices in place. • See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by the manufacturer. • Stop the blade(s) when crossing gravel drives, walks, or roads. • Stop the engine (motor) whenever you leave the equipment, before cleaning the mower or unclogging the chute. • Shut the engine (motor) off and wait until the blade comes to complete stop before removing grass catcher. • Mow only in daylight or good artificial light. • Do not operate the machine while under the influence of alcohol or drugs. • Never operate machine in wet grass. Always be sure of your footing: keep a firm hold on the handle; walk, never run. • Disengage the self-propelled mechanism or drive clutch on mowers so equipped before starting the engine. • If the equipment should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibration is generally a warning of trouble. II. SLOPE OPERATION Slopes are a major factor related to slip & fall accidents which can result in severe injury. All slopes require extra caution. If you feel uneasy on a slope, do not mow it. DO: • Mow across the face of slopes: never up and down. Exercise extreme caution when changing direction on slopes. • Remove obstacles such as rocks, tree limbs, etc. • Watch for holes, ruts, or bumps. Tall grass can hide obstacles. DO NOT: • Do not trim near drop-offs, ditches or embankments. The operator could lose footing or balance. • Do not trim excessively steep slopes. • Do not mow on wet grass. Reduced footing could cause slipping. III. CHILDREN Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them. • Keep children out of the trimming area and under the watchful care of another responsible adult. • Be alert and turn machine off if children enter the area. • Before and while walking backwards, look behind and down for small children. • Never allow children to operate the machine. • Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision. IV. SAFE HANDLING OF GASOLINE Use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. • Extinguish all cigarettes, cigars, pipes and other sources of ignition. • Use only an approved container. • Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling. • Never refuel the machine indoors. • Never store the machine or fuel container where there is an open flame, spark or pilot light such as a water heater or on other appliances. 3 • Never fill containers inside a vehicle, on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling. • Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle. • Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device. • If fuel is spilled on clothing, change clothing immediately. • Never overfill fuel tank. Replace gas cap and tighten securely. • Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition. • Never tamper with safety devices. Check their proper operation regularly. • Keep machine free of grass, leaves, or other debris build-up. Clean oil or fuel spillage. Allow machine to cool before storing. • Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting. • Never attempt to make wheel height adjustments while the engine is running. • Grass catcher components are subject to wear, damage, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace with manufacturer’s recommended parts, when necessary. • Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when ser vicing them. • Do not change the engine governor setting or overspeed the engine. • Maintain or replace safety and instruction labels, as necessary. V. GENERAL SERVICE • Never run a machine inside a closed area. • Never make adjustments or repairs with the engine (motor) running. Disconnect the spark plug wire, and keep the wire away from the plug to prevent accidental starting.

Always wear safety glasses or eye shields while operating your lawn mower or performing any adjustments or repairs. We recommend a standard safety glasses or wide vision safety mask worn over spectacles. TO ENGAGE Adjustment turnbuckle DRIVE (on underside) CONTROL HOW TO USE YOUR LAWN MOWER Drive control lever DRIVE CONTROL DISENGAGED DRIVE CONTROL ADJUSTMENT Over time, the drive control system may become “loose”, resulting in decreased speed. There is a turnbuckle on the underside of the drive control housing to increase tension on the drive cable. Proceed as follows: 1. Turn unit off and disconnect spark plug wire from spark plug. 2. Turn nut on underside of drive control to increase drive speed. 3. Operate mower to test drive speed. Readjust as required. 4. If condition fails to improve after the above steps (forward speed remains the same), your drive belt is worn and should be replaced. 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 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. DRIVE CONTROL • Self-propelling is controlled by holding the operator presence control bar down to the handle and pulling the drive control lever rearward to the handle. The farther toward the handle the lever is pulled, the faster the unit will travel. • Forward motion will stop when either the operator presence control bar or drive control lever are released. To stop forward motion without stopping engine, release the drive control lever only. Hold operator presence control bar down against handle to continue mowing without self-propelling. NOTE: If after releasing the drive control the mower will not roll backwards, push the mower forward slightly to disengage drive wheels. • To keep drive control engaged when turning corners, push down on the handle to lift the front wheels off the ground while turning lawn mower.

Open mulcher door 9 TO EMPTY GRASS CATCHER 1. Lift up on grass catcher using the frame handle. 2. Remove grass catcher with clippings from under lawn mower handle. 3. Empty clippings from bag. NOTE: Do not drag the bag when emptying; it will cause unnecessary wear. 1. Snap cartridge into bottom of fuel cap. NOTE: Do not remove the silver foil seal on the side of cartridge that snaps into fuel cap. 2. Grasp the white peel tab and pull to remove the entire seal. 3. Screw fuel cap onto fuel tank after filling tank with gasoline. Replace cartridge when empty (about once a season). Check preserver level visually. DANGER: Cartridge fluid is HARMFUL OR FATAL IF SWALLOWED. Avoid contact to eyes, skin, or clothing. Do not take internally. Do not inhale fluid vapor. Keep out of reach of children. If swallowed, call a physician immediately. ADD GASOLINE • Fill fuel tank to bottom of tank filler neck. Do not overfill. 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. CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. CAUTION: 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. Empty 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. Grass catcher frame handle BEFORE STARTING ENGINE ADD OIL Your lawnmower is shipped without oil in the engine. For type and grade of oil to use, see “ENGINE” in the Maintenance section of this manual. CAUTION: DO NOT overfill engine with oil, or it will smoke heavily from the muffler on startup. 1. Be sure lawnmower is level. 2. Remove oil dipstick from oil fill spout. 3. You receive a container of oil with the unit. Slowly pour the entire container down the oil fill spout into the engine. NOTE: Initial oil fill requires only 18 oz. due to residual oil in engine from the manufacturers 100% quality testing. When changing oil you may need 20 oz. 4. Insert and tighten dipstick. IMPORTANT: • Check oil level before each use. Add oil if needed. Fill to full line on dipstick. • 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. See “TO CHANGE ENGINE OIL” in the Maintenance section of this manual. ATTACH FUEL CAP CARTRIDGE Your mower is equipped with a special FRESH STARTTM fuel cap and continuous fuel preserver cartridge. See the information and instructions packed with the FRESH STARTTM cartridge. Engine oil cap Gasoline filler cap 10 TO STOP ENGINE MULCHING MOWING TIPS • To stop engine, release operator presence control bar. IMPORTANT: For best performance, keep mower housing free of built-up grass and trash. See “CLEANING” in the 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 clumps and interferes with the mulching action. The best time to mow your lawn is the early afternoon. At this time the grass has dried, yet the newly cut area will not be exposed to direct sunlight. • 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 grass, reduce your width of cut by overlapping previously cut path and mow slowly. TO START ENGINE NOTE: Due to protective coatings on the engine, a small amount of smoke may be present during the initial use of the product and should be considered normal. NOTE: Your engine is equipped with an automatic choke system. No priming or choking is required before starting. • To start engine, hold operator presence control bar down to the handle and pull starter handle quickly. Do not allow starter rope to snap back. MOWING TIPS CAUTION: Do not use de-thatcher blade attachments on your mower. Such attachments are hazardous, will damage your mower and could void your warranty. • 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. • 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. MAX 1/3 • 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 (perpendicular) to the first cut path. • Change your cutting pattern 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. 11 MAINTENANCE BEFORE EACH USE AFTER EACH USE EVERY 10 HOURS EVERY 25 HOURS OR SEASON EVERY 100 HOURS BEFORE STORAGE Check for Loose Fasteners Clean / Inspect Grass Catcher * Check Tires Check Drive Wheels *** Clean Lawn Mower **** Clean under Drive Cover *** Check Drive Belt / Pulleys *** Check / Sharpen / Replace Blade Lubrication Clean and Recharge Battery ** Check Engine Oil level Change Engine Oil Clean Air Filter Inspect Muffler Replace Spark Plug Replace Air Filter Paper Cartridge Empty fuel system or add Stabilizer * (if so equipped) ** Electric-Start mowers *** Power-Propelled mowers a scraper **** Use to clean under deck 1 - Change more often if operating under a heavy load or in high outdoor temperatures. 2 - Service more often if operating in dirty or dusty conditions. 3 - Replace blades more often when mowing in sandy soil. 4 - Charge 48 hours at end of season. 5 - And after each 5 hours of use. LUBRICATION CHART GENERAL 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 unit as instructed in this manual. Some adjustments will need to be made periodically to properly maintain your unit. At least once a season, check to see if you should make any of the adjustments described in the Service and Adjustments section of this manual. • At least 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 assure proper air-fuel mixture and help your engine run better and last longer. • Follow the maintenance schedule in this manual. ➀ Wheel adjuster (on each wheel) ➁ Engine oil ➀ Mulcher door hinge pin ➀ Rear door hinge ➀ Handle bracket mounting pins ➀ Spray lubricant ➁ See "ENGINE" in Maintenance section. BEFORE EACH USE • Check engine oil level. • Check for loose fasteners. LUBRICATION Keep unit well lubricated (See “LUBRICATION CHART”). 12 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, powdered graphite type lubricant sparingly. LAWN MOWER Always observe safety rules when performing any maintenance. TIRES • Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber. • Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage. 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. If necessary to clean the drive wheels, be sure to clean both front wheels. 1. Remove hubcaps, locknuts & washers. 2. Remove wheels from wheel adjusters. 3. Remove any trash or grass cuttings from inside the dust cover, pinion and/ or drive wheel gear teeth. 4. Put wheels back in place. NOTE: If after cleaning, the drive wheels do not turn freely, contact a Sears or other qualified service center. BLADE CARE For best results, blade must be kept sharp. Replace a bent or damaged blade. CAUTION: Use only a replacement blade approved by the manufacturer of your mower. Using a blade not approved by the manufacturer of your mower is hazardous, could damage your mower and void your warranty. 4. Use block of wood between blade and lawn mower housing and tighten the blade bolt, turning clockwise. • The recommended tightening torque is 35-40 ft. lbs. IMPORTANT: Blade bolt is heat treated. If bolt needs replacing, replace only with approved bolt shown in the Repair Parts section of this manual.

SQUEEZE TO FOLD Lower handle Operator presence control bar FOLD FORWARD FOR STORAGE MOWING POSITION Upper handle Handle knob Lower handle 16 ENGINE FUEL SYSTEM IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor, fuel filter, fuel hose, or tank during storage. 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. • Empty the fuel tank by starting the engine and letting it run until the fuel lines and carburetor are empty. • Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. • Use fresh fuel next season. NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not empty the gas tank and carburetor if using fuel stabilizer. NOTE: FRESH STARTTM fuel cap and cartridge system automatically drips concentrated fuel preserver into your fuel tank and is an acceptable alternative to adding fuel stabilizer. ENGINE OIL Drain oil (with engine warm) and replace with clean engine oil. (See “ENGINE” in the Maintenance section of this manual). CYLINDER 1. Remove spark plug. 2. Pour one ounce (29 ml) of oil through spark plug hole into cylinder. 3. Pull starter handle slowly a few times to distribute oil. 4. Replace with new spark plug. OTHER • Do not store gasoline from one season to another. • Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems. • If possible, store your unit indoors and cover it to protect it from dust and dirt. • Cover your unit with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot breathe, which allows condensation to form and will cause your unit to rust. IMPORTANT: Never cover mower while engine and exhaust areas are still warm. CAUTION: Never store the lawn mower with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure.
