the personal safety and/or property of yourself and others. Read and follow all instructions in this manual before attempting to operate this machine. Failure to comply with these instructions may result in personal injury. When you see this symbol--HEED ITS WARNING. WARNING: Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to State of California to cause cancer and birth defects or other reproductive harm. WARNING: This machine was built to be operated according to the rules for safe operation in this manual. As with any type of power equipment, carelessness or error on the part of the operator can result in serious injury. This machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death. GeneralOperation 1. Read this operator's manual carefully in its entirety before attempting to assemble this machine. Read, understand, and follow all instructions on the machine and in the manual(s) before operation. Be completely familiar with the controls and the proper use of this machine before operating it. Keep this manual in a safe place for future and regular reference and for ordering replacement parts. 2. This machine is a precision piece of power equipment, not a plaything. Therefore, exercise extreme caution at all times. Your unit has been designed to perform one job: to mow grass. Do not use it for any other purpose. 3. Never allow children under 14 years old to operate this machine. Children 14 years old and over should read and understand the operation instructions and safety rules in this manual and should be trained and supervised by a parent. Only responsible individuals who are familiar with these safe operation rules should use this machine. 4. Thoroughly inspect the area where equipment is to be used. Remove all stones, sticks, wire, bones, toys and other foreign objects which could be tripped over or picked up and thrown by the blade. Thrown objects can cause serious personal injury. Plan your mowing pattern to avoid discharge of material toward roads, sidewalks, bystanders and the like. Also, avoid discharging material against a wall or obstruction which may cause discharged material to ricochet back toward the operator. 5. To help avoid blade contact or a thrown object injury, stay in the operator zone behind the handles and keep bystanders, helpers, children and pets at least 75 feet from the machine while it is in operation. Stop machine if anyone enters the area. 6. Always wear safety glasses to protect your eyes during equipment operation and while performing an adjustment or repair. Thrown objects which ricochet can cause serious injury to the eyes. 7. Wear sturdy, rough-soled work shoes and close- fitting slacks and shirts. Shirts and pants that cover the arms and legs and steel-toed shoes are recommended. Never operate this machine in bare feet, sandals, slippery or light weight (e.g. canvas) shoes. 8. Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade can amputate hands and feet. 9. A missing or damaged discharge cover can cause blade contact or thrown object injuries. 10. Many injuries occur as a result of the mower being pulled over the foot during a fall caused by slipping or tripping. Do not hold on to the mower if you are falling; release the handle immediately. 11. Never pull the mower back toward you while you are walking. If you must back the mower away from a wall or obstruction first look down and behind to avoid tripping and then follow these steps: a. Step back from the mower to fully extend your arms. b. Be sure you are well balanced with sure footing. c. Pull the mower back slowly, no more than half way toward you. d. Repeat these steps as needed. 5. Do not operate the mower while under the influence of alcohol or drugs. 6. Do not engage the self-propelled mechanism on units so equipped while starting engine. 7. The blade control handle is a safety device. Never attempt to bypass its operation. Doing so makes the safety device inoperative and may result in personal injury through contact with the rotating blade. The blade control handle must operate easily in both directions and automatically return to the disengaged position when released. 8. Never operate the mower in wet grass. Always be sure of your footing. A slip and fall can cause serious personal injury. If you feet you are losing your footing, release the blade control handle

Slopes are a major factor related to slip and fall

accidents which can result in severe injury. Operation on slopes requires extra caution. If you feel uneasy on a slope, do not mow it. Before operating this unit on a slope or hilly area, use the slope gauge on page 6 to measure slopes. If the slope is greater than 15 degrees, do not mow it. Be: 1. Mow across the face of slopes; never up and down. Exercise caution when changing direction. 2. Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you to slip or trip. Tall grass can hide obstacles. 3. Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your balance, release the blade control handle immediately, and the blade will stop rotating within 3 seconds. DoNot: 1. Do not mow near drop-offs, ditches or embankments, you could lose your footing or balance. 2. Do not mow slopes greater than 15 degrees as shown on the slope gauge. 3. Do not mow on wet grass. Unstable footing could cause slipping. Children Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the mower and the mowing activity. They do not understand the dangers. Never assume that children will remain where you last saw them. 1. Keep children out of the mowing area and under the watchful care of a responsible adult other than the operator. 2. Be alert and turn mower off if a child enters the area. 3. Before and while moving backwards, look behind and down for small children. 4. Use extreme care when approaching blind corners, doorways, shrubs, trees, or other objects that may obscure your vision of a child who may run into the mower. 5. Keep children away from hot or running engines. They can suffer burns from a hot muffler. 6. Never allow children under 14 years old to operate a power mower. Children 14 years old and over should read and understand the operation instructions and safety rules in this manual and should be trained and supervised by a parent. Service SafeHandlingof Gasoline: 1. To avoid personal injury or property damage use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. 2. Wash your skin and change clothes immediately. 3. Use only an approved gasoline container. 4. Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling. 5. If possible, remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle. 6. 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. 7. Extinguish all cigarettes, cigars, pipes and other sources of ignition. 8. Never fuel machine indoors because flammable vapors will accumulate in the area. 9. Never remove gas cap or add fuel while the engine is hot or running. Allow engine to cool at least two minutes before refueling.

Never run an engine indoors or in a poorly

ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas. 2. Before cleaning, repairing, or inspecting, make certain the blade and all moving parts have stopped. Disconnect the spark plug wire and ground against the engine to prevent unintended starting. 3. Check the blade and engine mounting bolts at frequent intervals for proper tightness. Also, visually inspect blade for damage (e.g., bent, cracked, worn) Replace blade with the original equipment manufacture's (O.E.M.) blade only, listed in this manual. "Use of parts which do not meet the original equipment specifications may lead to improper performance and compromise safety!" 4. Mower blades are sharp and can cut. Wrap the blade or wear gloves, and use extra caution when servicing them. 5. Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition. 6. Never tamper with safety devices. Check their proper operation regularly. 7. After striking a foreign object, stop the engine, disconnect the spark plug wire and ground against the engine. Thoroughly inspect the mower for any damage. Repair the damage before starting and operating the mower. 8. Never attempt to make a wheel or cutting height adjustment while the engine is running. 9. Grass catcher components, discharge cover, and trail shield are subject to wear and damage which could expose moving parts or allow objects to be thrown. For safety protection, frequently check components and replace immediately with original equipment manufacturer's (O.E.M.) parts only, listed here. Use of parts which do not meet the original equipment specifications may lead to improper performance and compromise safety. 10. Do not change the engine governor setting or overspeed the engine. The governor controls the maximum safe operating speed of the engine. 11. Maintain or replace safety and instruction labels, as necessary. 12. Observe proper disposal laws and regulations. Improper disposal of fluids and materials can harm the environment. 13. ALWAYS de-energize self starter prior to pertorming any maintenance or service to the engine and or mower.

UsingYourLawnMower • Do not operate the mower without any one of the mulching baffle, discharge chute or grass catcher properly installed. • For best results, do not cut wet grass. It may stick to the underside of the mower, preventing proper discharge of grass clippings, and could cause you to slip and fall. New grass or thick grass may require a narrower cut. • For a healthy lawn, always cut off one-third or less of the total length of the grass. Lawn should be trimmed in fall as long as there is growth. IMPORTANT: Move the shift lever only when the engine is running. Changing the shift lever setting with the engine off can cause damage to the mower. WARNING: If the mower strikes a foreign object, stop the engine. Remove spark plug wire from the spark plug and thoroughly inspect for any damage. Repair the damage promptly before restarting and operating the mower. WARNING: Be sure that the lawn is clear of stones, sticks, wire, or other objects which could damage lawn mower or engine. Such objects could be accidently thrown by the mower in any direction and cause serious personal injury to the operator and others. Mulching For effective mulching, do not cut wet grass. New or thick grass may require a narrower cut. If the grass has grown in excess of 4", mulching is not recommended. Mow using the side discharge to reduce the grass height to 3.25" maximum before mulching. BaggingGrassClippings You can use the grass catcher bag to collect clippings while you are operating the mower. • Attach grass catcher following instructions on page 8 of this manual. Grass clippings will automatically collect in the bag as you run the mower. • Operate the mower till the grass bag is full. • Stop engine completely by releasing the blade control handle.
