IMPORTANT
Safe Operation Practices for Walk–Behind Mowers.
This cutting 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.
I. General Operation
1. Read, understand, and follow all instruc­tions on the machine and in the manual(s). Be thoroughly familiar with the controls and the proper use of the mower before starting.
2. Do not put hands or feet near or under rotat­ing parts. Keep clear of the discharge open­ing at all times.
3. Only allow responsible individuals, who are familiar with the instructions, to operate the mower.
4. Thoroughly inspect the mower and area where the equipment is to be used. Clear the area of objects such as rocks, toys, wire, bones, sticks etc., which could be picked up and thrown by the blade.
5. Be sure the area is clear of other people be­fore mowing. Stop mower if anyone enters the area.
6. Do not operate the mower when barefoot or wearing open sandals. Always wear sub­stantial foot wear.
7. Do not pull mower backwards unless abso­lutely necessary. Look down and behind be­fore and while moving backwards.
8. Do not operate the mower without proper guards, plates, grass catcher or other safety protective devices in place.
9. See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by the manufacturer.
10. Stop the blade(s) when crossing gravel drives, walks, or roads.
11. Stop the engine (motor) whenever you leave the equipment, before cleaning the mower or unclogging the chute.
12. Shut the engine (motor) off and wait until the blade comes to complete stop before re­moving grass catcher.
13. Mow only in daylight or good artificial light.
14. Do not operate the mower while under the influence of alcohol, drugs or other medica-
F–040406L
tion which can cause drowsiness or affect your ability to operate this machine safely.
15. Never operate mower in wet grass. Always be sure of your footing; keep a firm hold on the handle and walk; never run.
16. Disengage the self–propelled mechanism or drive clutch on mowers so equipped be­fore starting the engine (motor).
17. 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 such as a blade that is damaged, a loose blade, or the en­gine mounting bolts are loose.
18. Always wear safety goggles or safety glasses with side shields when operating mower to protect your eyes from foreign ob­jects which can be thrown from the unit.
19. Plan your mowing pattern to avoid dis­charge of material toward roads, sidewalks, bystanders and the like.
20. After striking a foreign object, stop the en­gine. Remove the wire from the spark plug. Inspect the blade and mower for damage. If damaged, repair before starting and operat­ing the mower.
21. Keep any washout ports and other mower housing service openings closed when mowing.
II. Slope Operation
Slopes are a major factor related to slip and 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. Do not mow excessively steep slopes (maximum 15 degrees) or areas where the ground is very rough. See the “Guide” in the back of this manual to check a slope. Exercise extreme caution when changing direction on slopes.
Remove objects such as rocks, tree limbs, etc.
Watch for holes, ruts, or bumps. Tall grass can hide obstacles.

(Continued Following Page)
DO NOT:
IMPORTANT
Do not mow near drop–offs, ditches, or em­bankments. The operator could lose footing or balance.
Do not mow 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 mower and the mowing activity. 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.
2. Be alert and turn mower off if children enter the area.
3. Before and while moving backwards, look behind and down for small children.
4. Never allow children to operate the mower.
5. Use extra care when approaching blind cor­ners, shrubs, trees, or other objects that may obscure vision.
IV. Service
*1. Use extra care in handling gasoline and oth-
er fuels. They are flammable and vapors are explosive.
a. Use only an approved container.
b. Never remove gas cap or add fuel with
the engine running. Allow engine to cool before refueling. Do not smoke.
c. Never refuel the machine indoors.
d. Never store the machine or fuel contain-
er inside where there is an open flame, such as a water heater.
*2. Never run an engine indoors or inside a
closed area.
3. Never make adjustments or repairs to items such as the height adjusters or grass catch­er with the engine (motor) running. Discon-
nect the spark plug wire, and keep the wire away from the plug to prevent accidental starting. Always wear eye protection when you make adjustments or repairs.
4. Keep all nuts and bolts, especially blade at­tachment bolts, tight and keep equipment in good condition.
5. Never tamper with safety devices. Check their proper operation regularly.
6. To reduce fire hazard, keep mower free of grass, leaves, or other debris build–up. Clean up oil or fuel spillage. Allow mower to cool before storing.
7. Stop and inspect the equipment if you strike an object. Repair, if necessary, before re­starting.
8. Never attempt to make wheel height adjust­ments while the engine (motor) is running.
9. Always disconnect electric mowers (live op­erated) before cleaning, repairing, or ad­justing.
10. 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. For stor­age, always make sure grass catcher is empty.
11. Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them.
12. Do not change the engine governor setting or over–speed the engine.
13. Frequently check the blade for wear or dam­ages such as cracks and nicks. A blade that is bent or damaged must be immediately re­placed with a factory replacement blade. For safety and good cutting performance, replace the blade every two years. Fre­quently check the blade bolt and the engine mounting bolts. Replace damaged bolts and tighten loose bolts.
14. Use only original equipment or authorized replacement parts.

Every person who uses power equipment
SAFE MOWING GUIDE
must learn the difference between proper and improper use, safe and unsafe mowing prac­tices. Read the next few pages carefully. They can help you learn. Too often the mow­er user is inexperienced, not properly in­structed, or has not read the Instruction Book and instructions on the unit before using it for the first time. This can result in unsafe use en­dangering the operator, bystanders, and the equipment. Another result can be a poor ap­pearance of the area mowed.
Read this Instruction Book. Read the in­structions on the unit. Operate the mower ac­cording to the Safe Mowing Guide and other safety rules and recommendations in this In­struction Book and on the unit. Make sure any­one who uses the unit has read the instructions and has been told how to operate the mower safely.
Your mower is designed to provide good ser­vice and durability in normal residential cut­ting. If the mower is not properly serviced and maintained or used on unsuitable terrain or in conditions not suitable for mowing, product performance and safety will be reduced.
Proper attire is an important part of safe mow­ing. Safety glasses protect the eyes from thrown objects. Safety shoes with steel toes can protect a foot from being cut by the blade. Shirts and pants that cover the arms and legs can stop or deflect a thrown object.
gency. Learn how to cut and how to keep con­trol of the mower at all times.
Many mowers are started manually. When us­ing a pull start or rope start, place your feet firmly and away from the blade. Hold the rope handle securely, but never wrap the rope around your arm or fingers for a “better grip”.
The mower is designed for use by one person. Always mow alone. Never carry passengers. Carrying a passenger is dangerous for the passenger and the operator. A mower is not for amusement or for carrying objects.
Is the area you are planning to mow wet? Nev­er cut a wet lawn. Cutting wet grass can cause an accident. It can affect mower performance and also cause problems with future lawn growth and appearance. Wet grass is slippery and might cause the operator to fall or the mower to slip. Someone could be hurt by touching the blade. Wet grass tends to clog the mower, causing poor discharge. Wet clippings bunch up on the lawn retarding the growth of grass. A wet mower can cause parts to rust and reduce the useful life of the unit.
Practice using the mower before you actually begin cutting grass. Select a large open level area. Learn the location and function of the controls and how they work. It is important that the blade can be stopped quickly in an emer-
F–040406L
When you look over the lawn, refresh your memory about hard, immovable obstacles such as pipes, stumps, and rocks and avoid them. They can cause damage to the mower or an accident injuring the operator or a by­stander. Take a litter bag along and walk over the area to be cut. Pick up any stones, toys, wire, bones, or other loose objects. These items can damage the mower or they can be­come dangerous flying objects if the mower blade hits them. The blade of a power mower travels very fast. It can throw rocks and other objects with force over long distances. Objects thrown by mowers can break windows, cause
6
bruises, or even put out an eye. Often the per-
SAFE MOWING GUIDE
son hurt by a thrown object is a bystander such as a child, another family member or a neigh­bor. Keep people and pets completely away from the mowing area. Direct the mower’s dis­charge away from areas where people can be. Planning your mowing pattern has a double benefit. It can reduce chances of an injury and make the clean up after mowing easier.
Are there ditches, walls, or major in­clines in the area to be cut? Plan the mowing pattern to avoid such danger areas. In­clines and rough ter­rain must be mowed carefully and some areas must not be cut with a mower at all. With walk behind equipment, mow across the incline so that if you or the mow­er slip, you won’t run into each other.
Never mow slopes greater than 15 degrees. See the “Guide” in the back of this Instruction Book to check any slopes.
Ready to start cutting? Not yet. Be sure the mower has been fully assembled according to directions in the Instruction Book. Even if as­sembly was done by a lawn and garden shop or the store where the unit was purchased, it must be checked. Are all nuts, bolts and screws tight? Does the engine have oil? These items must be checked periodically throughout the life of the mower.
Your mower has a gasoline engine. Gas is dangerous. Store fuel only in a approved gas container. Do not store large amounts of gas. Put out all cigarettes, pipes and cigars before working with gasoline. Store fuel and the mow­er itself in a well ventilated area away from any possible source of ignition such a pilot light on a furnace. If the mower is to be stored for an ex­tended time, remove the gas from the tank. This minimizes the chance of a fire and keeps the tank clear of deposits and old gasoline, thus improving mower performance. Move the mower outside before adding gasoline. Use a funnel and wipe up any spilled fuel before start­ing. Remember, gasoline expands when heated so leave some expansion room. Also, most mower gas caps are vented to allow for expansion. Always use the proper cap. People are needlessly burned by fires, hurt in explo­sions, mowers and other property are dam­aged because of failure to follow basic safety rules related to gasoline and fueling.
Never add gasoline to an engine that is running or that is hot from recent use, this can cause an accident. Remove dry grass and other debris from the mower. Keeping the mower clean will
F–040406L
improve the performance, help the engine stay cooler, extend the life of moving parts, and minimize the danger of fire. People get burned working with and around their mowers for oth­er reasons than fire and explosions. It takes only a few seconds of operation for the engine and the muffler to become hot. Do not touch these parts when the mower is running. Stop the engine and let it cool down before servicing the mower. Remember, exhaust fumes can be dangerous. Never operate the engine indoors or in an enclosed area.
Getting a new mower can be a big event for a family. Let family members satisfy their curios­ity about the mower and at the same time, tell them about its dangers. Remember, a mower is not a toy and is not for use by children or any­one lacking in age, strength or experience.
As with any power equipment, a mower can be dangerous if not assembled, misused, or not properly maintained. The most important rule is to always use good judgement and common sense.
Your mower will cut thick grass and heavy plant stems with ease. Fingers and toes are no more resistant to the mower’s blade. Many people are injured because they “forgot” and reached into the discharge chute. Always treat your lawn mower as if the blade is rotating. Never perform any service or try to make any adjustment,except carburetor, while the en­gine is running.
Use only accessories suited for your mower. Use of improper accessories can reduce the safety designed into both the mower and the accessory, it can even damage the unit. Read and follow the instructions which come with the accessory and the mower.

Use only original equipment or approved sub-

stitutions as service parts. If you need profes­sional service, select a shop that is an Authorized Service Center for your brand of mower. If you plan to service the unit yourself, follow directions in the Instruction Book.
in the rain is no fun and it is dangerous. Always seek shelter in an electrical storm. In extreme­ly dry mowing conditions, your safety glasses can serve a dual purpose by protecting your eyes from dust and thrown objects, also a dust or pollen mask can be helpful.
As you mow, remember children and pets are sometimes attracted to the activity. Be espe­cially careful when trimming around shrubbery or when backing up. If at all possible, don’t mow when moving backwards. It is dangerous because vision is restricted. Also, blades are designed to cut while the unit is moving for­ward so cutting performance is reduced when mowing in reverse.
Never leave the mower running and unat­tended. Shut off the engine. Put the mower in a position so that it can not roll. If the unit is self–propelled, make sure the drive control is disengaged.
When mowing, be aware of your condition and the weather conditions. After mowing a long time, you will be tired. This is the time when reactions slow down, your attention wanders; the time when you are wide open for an acci­dent. Take a short break. If temperatures are high, take precautions to avoid becoming de­hydrated. If you are angry, tired, or unable to give your full attention to mowing, if you have been consuming alcohol, medicines, or drugs, do not use your mower or any type of power equipment.
If weather conditions become worse while you are cutting, stop and finish later. Cutting grass
F–040406L
Your mower is equipped with a number of safe­ty features which are important to the safety of the operator and bystanders and must never be altered or removed. If a safety feature be­comes inoperable, lost, or damaged, it must be repaired or replaced before the mower is used.
Engine speed is a key to safe mowing and a nice looking lawn. The maximum speed of the engine on your mower has been set at the fac­tory. Do not change the engine governor in any way.
Select the maximum engine and ground speed that is right for the terrain and the height of grass. You get the best cutting and bagging performance when using a grass catcher by operating the engine at maximum speed. Nev­er walk fast or run just to get the job done soon­er. On inclines, reduce ground speed and exercise extreme care.
It is best to mow only during daylight hours; however, if you must mow in the late afternoon or evening, make sure there is good artificial light.
Your mower will require maintenance including service and adjustments before and after use as with any machine. The frequency of the maintenance is generally based on hours of use, however, the frequency can vary because of mowing conditions. Check the Instruction Book for more detailed instructions. Proper maintenance protects your investment in the mower and helps insure that it will function safely and reliably.
Never attempt any service (with the pos­sible exception of car­buretor adjustment) with the engine run­ning. After turning the engine off, always disconnect the spark plug wire to prevent accidental restarting while the unit is being serviced.

While mowing, if you hit a foreign object, stop
SAFE MOWING GUIDE
the engine. Remove the spark plug wire. Care­fully and thoroughly inspect the mower for damage. Make necessary repairs before re­starting. If the unit starts to vibrate abnormally, stop the engine immediately and check for the cause. Vibration is generally a warning of trouble. Keep all nuts, bolts, and screws tight.
The blade is the most dangerous part of the mower and also the most important part in ob­taining a nice lawn appearance. Check the blade and the blade mounting hardware fre­quently. Keep it tight. If the blade hits a solid object, check it thoroughly for deformation or cracks and replace if damaged. For safety,re­place the blade every two years. A sharp blade reduces the work load on the engine and cuts grass more cleanly, for a better looking cut with less work. The blade is always close to the out­side of the mower housing. For best trimming on side discharge mowers, cut with the left side of the housing toward the area that needs trimming.
A useful accessory for your mower is a grass catcher. There are grass catchers available for most models. For best performance and safe­ty, be sure the grass catcher is approved for use with your mower. Assemble as directed and follow operating and safety instructions with the catcher and in the Instruction Book.
Before mounting, checking or emptying the grass catcher, always turn the engine off. Re­member to check the grass catcher before each use for cracks, wear, or deterioration. Re­place any part that is damaged with the man­ufacturer’s recommended replacement part before using the grass catcher again.
Proper cutting technique is important if you want your lawn to look good. Avoid the tempta­tion to cut grass too short. Cutting grass too short can kill the plant, cause grass to turn yel­low, or make the lawn look brown and thatchy. Use the lower cutting heights in cool months when the grass is lush. Use the higher cutting heights in extremely dry periods. Cutting with a dull blade or low engine speed bruises, shreds, and can uproot some grass making the lawn look dull and brown a few days after cutting. Always put the throttle control in FAST
F–040406L
position when mowing and bagging. When bagging, slower ground speed will provide the best results.
Change the mowing pattern slightly each time you cut. If you always cut the same way, the grass will develop a “set” and clippings will ac­cumulate more heavily in some areas more than in others causing grass to get thinner in those areas. Do not service your mower over the grass. Spilled oil and gas can kill the grass. In tall grass or very heavy grass, do not try to cut it all at once. Raise the height of cut on the first cutting and lower it for the next cutting the same day or within a few days. Another way is to cut only part of the width of the mower and adjust your ground speed (not the engine) to move more slowly so the mower can clear it­self as it moves forward.
When cutting with a walk behind mower, al­ways push the unit. Do not pull it. Pushing the unit keeps the operator behind the mower in the “operator’s zone” for better control. Push­ing the unit also gives you a chance to see ex­actly where and what you are mowing. There will be times while you are mowing that you will have to pull the mower backwards (such as when the front of the mower has come up against a wall or fence). If you must back up, make sure your feet are in the clear. Stand well back from the mower, plant your feet firmly with each step and back up being careful to look be­hind you. Resume normal mowing as soon as possible.
If your unit is self–propelled, remember that the drive mechanism is not designed to do all the work, but the unit can move without your help. Always keep your hands on the handle near the controls when the engine is running. Remember too that the self–propelled mecha­nism can be dangerous. Keep hands and feet away from belts and chains. Always turn off the engine before attempting to remove anything that becomes entangled in the self–propelled system.
Remember, your mower is a useful tool, but it can be dangerous. Follow the instructions in this Instruction Book. Use the mower properly and carefully and it will give you many hours of trouble free, accident free operations.

STEPS TO FOLLOW
BEFORE MOWING
D Be sure to dress correctly. Wear hard shoes, not sandals or tennis shoes. D Examine the blade. A blade that is bent, cracked, or damaged must be replaced with a factory
replacement blade.
D Fill the fuel tank outside. Clean off spilled fuel. D Read and follow the Owner’s Manual, the instructions with the engine, and the instructions with
any attachments. Owner’s Manual instructions are for your safety and the safety of others.
D Exhaust fumes are dangerous. Start the engine outside. D Make sure all safety devices are in place and working correctly. D Operation of the mower is only for a person that has experience. D Wet grass can be dangerous. Let the grass dry. D Instruct children and others to keep away from the work area. D Never cut the grass without good light. D Pick up loose objects. Remove them from the mowing area.
WHILE MOWING
D Watch for fixed objects and avoid them. They can damage the mower or cause injury. D A hot engine and muffler will cause a burn. Do not touch. D Inclines and slopes must be carefully mowed. See the “Guide” in the back of this book to check
a slope.
D Lack of daylight or good artificial light is cause to stop mowing. D Examine the mower, the blade, and other parts for damage after hitting a foreign object or if the
unit vibrates excessively.
D Do not make adjustments or repairs without stopping the engine (except for carburetor). Dis-
connect the spark plug wire.
D On or near roads, watch out for traffic. Direct discharge away from roads. D When mowing, avoid areas where traction is unsure. Before and while moving backwards, look
behind and down for small children.
D In heavy grass, raise the cutting height. Cut slower. Stop the engine to remove clogged grass
from the mower.
D Never remove any safety related parts. D Do not pour gasoline into a engine that is hot or running.
AFTER MOWING
D Always let the mower cool before storing in an enclosed area. D Foreign material on the mower is dangerous. Clean off grass, leaves, grease and oil before
storing.
D Tighten all loose nuts, bolts and screws before you use the unit. D Empty and clean any grass catcher or other accessory. D Remove the key or disconnect the spark plug wire to prevent unauthorized use. D Make sure the mower is not kept near a source of ignition. Gas fumes can cause an explosion. D Only original parts or factory approved substitutes can be used to service the mower. D When storing the mower for an extended period, remove the fuel from the fuel tank. D Instruct children to leave the mower alone. It is not a toy. D Never keep gasoline near a source of ignition. Always use an approved container. Keep
