Power Ratings: The power ratings for an individual engine mod- el are initially developed by starting with SAE (Society of Automo- tive Engineers) code J1940 (Small Engine Power & Torque

Rating Procedure) (Revision 2002-05). Given both the wide array of products on which our engines are placed, and the variety of

environmental issues applicable to operating the equipment, it may be that the engine you have purchased will not develop the

rated horsepower when used in a piece of power equipment (ac- tual "on-site" power). This difference is due to a variety of factors

including, but not limited to, the following: differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrica- tion, maximum governed engine speed, individual engine to en-

gine variability, design of the particular piece of power equipment, the manner in which the engine is operated, engine run-in to re- duce friction and clean out of combustion chambers, adjustments

to the valves and carburetor, and other factors. The power ratings may also be adjusted based on comparisons to other similar en-

gines utilized in similar applications, and will therefore not neces- sarily match the values derived using the foregoing codes.

NOTE: Actual sustained horsepower will likely be lower due to operating limitations and environmental factors.

attempting to start the engine.

Always wear goggles, safety glasses, or an eye shield when

you operate the unit to protect your eyes from foreign objects

that can be thrown from the unit. Always wear eye protection

when you make an adjustment or repair to the machine. Use care when pulling loads or using heavy equipment.

a. Use only approved drawbar hitch points. b. Limit loads to those you can safely control.

c. Do not turn sharply. Use care when backing. d. Use counterweights or wheel weights when suggested in the

Instruction Book. Do not operate this machine if you are taking drugs or other me-

dication which can cause drowsiness or affect your ability to op- erate this machine.

Do not use this machine if you are mentally or physically unable

to operate this machine safely.

21. Data indicates that operators, age 60 years and above, are in- volved in a large percentage of riding mower related injuries. These operators should evaluate their ability to operate a riding

mower safely enough to protect themselves and others from serious injury.

II. Slope operation

Slopes and rough terrain are major factors related to loss-of- control and tip-over accidents, which can result in severe inju-

ry or death. ALL slopes require extra caution. If you cannot back up the slope or if you feel uneasy on the slope, do not mow

it. See the "Slope Guide" in the back of this book to check for safe operation.

1. Mow up and down slopes, not across.

2. Remove obstacles such as rocks, limbs, etc...

3. Watch for holes, ruts or bumps. Uneven terrain could overturn the machine. Tallgrass can hide obstacles.

4. Follow the manufacturer's recommendations for wheel weights or counterweights to improve stability.

5. Use extra care with grass baggers or other attachments, they can change the stability of the machine.

6. Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction.

7. Avoid starting or stopping on a slope. If tires lose traction, turn off the blades and proceed slowly straight down the slope.

DO NOT

1. Do not turn on slopes unless absolutely necessary, then only turn slowly and gradually downhill, if possible.

2. Do not mow drop-offs, ditches or embankments. A wheel over the edge or an edge caving in could cause a sudden overturn and an injury or death.

3. Do not mow on wet grass. Reduced traction could cause slid- ing.

4. Do not try to stabilize the machine by putting your foot on the ground.

5. Do not use a grass bagger or other rear mounted accessories on steep slopes (greater than 10 degrees).

III. Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the ma-

chine and the mowing activity. NEVER assume that children will remain where you last saw them.

1. Keep children out of the mowing area and in the watchful care of another responsible adult.

2. Be alert and turn the engine off if children enter the area.

3. Before and when backing, look behind and down for small children.

SAFETY RULES

4. Never carry children or any passengers, even with the blades 5. off. They may fall off and be seriously injured or interfere with

the safe operation of the machine.

Never allow children to operate the machine. Instruct children in the potential dangers of the machine. 6.

Use extra care when approaching blind corners, shrubs, trees or other objects that may obscure vision. 7.

IV. Service

1. Use extra care when handling gasoline and other fuels. Fuels are flammable and the vapors are explosive.

a. Use only an approved container. b. Never remove the gas cap or add fuel with the engine run-

ning. Allow the engine to cool for several minutes before refueling. Do not smoke.

c. Never refuel the machine indoors or near appliances with

pilot lights, heaters, or other ignition sources.

d. Never store the machine with fuel in the tank or fuel con-

tainer inside where there is an open flame, such as a water

heater.

2. Never start or run the engine insidea closed area. a. Make sure that spark plug, muffler, fuel cap and air cleaner

are in place. b. Do not crank engine with spark plug removed. c. If fuel spills, wait until itevaporates before starting engine. d. Do not start ifthere is LP or natural gas leakage inthe area.

3. Keep all nuts and bolts, especially the blade attachment nuts tight. Frequently check the blade(s) for wear or damage such

as cracks and nicks. A blade that is bent or damaged must be immediately replaced with an original equipment blade from an authorized service dealer. For safety, replace the blade every

two years. Keep the equipment in good condition.

4. Never tamper with the safety devices. Check their proper oper-

ation regularly.

To reduce fire hazards, keep the machine free of grass, leaves or other debris build-up. Clean up oil or fuel spills. Allow the ma- chine to cool before storing.

a. Allow muffler and engine areas to cool before touching. Stop and inspect the equipment if you strike an object. Repair,

if necessary, before restarting. Never make adjustments or repairs with the engine running.

The carburetor can be adjusted with the engine running. Do not change the engine governor settings or over-speed the en- gine.

Grass bagger components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown. For storage, always make sure the grass bag is

empty. Frequently check components and replace with man- ufacturer's recommended parts when necessary.

Mower blade(s) are sharp and can cut. Wrap the blade(s) or wear gloves and use extra caution when servicing them or the

blade housing area.

10.

Check the brake operation frequently. Adjust and service as re- quired.

11.

Wait for all movement to stop before servicing any part of the unit.

HOW TO PREPARE THE ENGINE

NOTE: The engine was shipped from the factory filled with oil. Check the level of the oil. Add oil as needed.

CHECK THE TIRES

NOTE: The tires were over inflated for shipment. The correct air pressure is shown on the side of the tire.

Check the air pressure in the tires. Tires with too much air pressure will cause the unit to ride rough. Also, the wrong air pressure will keep the mower housing from cutting level. The correct air pressure

is shown on the side of the tire.

CHECK THE LEVEL OF THE MOWER HOUSING

Make sure the level of cut is still correct. After you mow a short distance, look at the area that was cut. If the mower housing does

not cut level, see the instructions on "How To Level The Mower Housing" in the Service And Adjustment section of this instruction

book.

NOTE: The operation of a new engine will sometimes result in a slight amount of smoke. This smoke is caused by paint or oil

on or around the muffler. This is normal and only expected during initial operation.

Before you use the unit, read the information on safety, operation, maintenance, and storage.

IMPORTANT! BEFORE YOU START MOWING

[] Check the engine oil. [] Fill the fuel tank with gasoline. [] Check the air pressure of the tires. [] Check the level of the mower housing.

[] Make sure the battery cables are attached. [] Make sure the wire is attached to the spark plug.

F-050610L 19

OPERATION

OPERATING TIPS

Check the attachment clutch for correct adjustment. For the blade(s) to disengage correctly, the adjustment must be cor-

rect.

Before you use the unit, check the oil in the engine and add oil if necessary.

If the engine will not start, first make sure the wire is attached

to the spark plug.

Make sure all the belts are inside all the belt guides. See the in- structions on how to remove and install the motion drive and

mower drive belts.

MOWING AND BAGGING TIPS

For a lawn to look better, check the cutting level of the mower housing. See "How To Level The Mower Housing" in the Ser-

vice And Adjustment section.

For the mower housing to cut level, make sure the tires have

the correct amount of air pressure (PSI) and use slow ground

speeds when turning.

Every time you use the unit, check the blade. If the blade is bent or damaged, immediately replace the blade. Also, make sure

the nut for the blade is tight.

Keep the blade(s) sharpened. A worn blade(s) will cause the ends of the grass to turn brown.

Do not cut or bag grass that iswet. Wet grass will not discharge correctly. Let the grass dry before cutting.

Use the left side of the mower housing to trim near an object.

Discharge the cut grass onto the mowed area. The result is a more even discharge of cut grass.

When you mow large areas, start by turning to the right so that the cut grass wilt discharge away from shrubs, fences, drive-

ways, etc. After one or two rounds, mow in the opposite direc-

tion making left turns until finished (Figure 14).

Use a mowing pattern that eliminates reverse travel as much as possible.

10.

If the grass is very high, cut two times to decrease the load on the engine. First cut with the mower housing in the highest posi- tion and then lower the mower housing for the second cut.

5. Before you make an inspection, adjustment (except for the car- buretor) or repair, make sure the wire from the spark plug is dis-

connected.

6. Make sure the seat switch wire is connected. If the wire is not connected, the engine will not start.

7. For longer life of the battery, charge the battery every three months.

8. Use the shift lever to change the ground speed, not the throttle control.

9. Belt noise can occur when the blade or clutch is engaged. This noise is normal and does not affect the operation of the unit.

10. To move forward, always release the clutch/brake pedal slowly.

11. For better engine performance and an even discharge of the cut grass, always operate the engine with the throttle in FAST

position.

12. When you use a bagger, operate the engine with the throttle in FAST position and the speed control lever in a slow forward

speed.

13. For better cutting performance and a quality cut, mow in a slow forward speed.

14. After each use, clean the bottom and top of the mower housing for better performance. Also, a clean mower housing will help

prevent a fire.

(

Figure14

MULCHING TIPS

When you use a mulcher attachment, the grass is cut into very small 4. pieces. These small pieces will quickly break down. Because the nutrients are returned to the soil, the lawn will need less fertilizer. Too correctly mulch the grass, follow the steps below.

1. Set the throttle in the FAST position. Operate the mower at a slower ground speed. If ground speed is too fast, the grass will 5.

not have an even cut.

2. Keep a sharp edge on the blade. A blade that is not sharp will cause the ends of the grass to become brown. 6.

3. Make sure the grass is dry. Wet grass is difficult to cut. 7.

F-050610L 20

Set the height of the mower housing so that only the top third of the grass is cut. If the grass is too high, set the height of the

mower housing to the maximum height. Then, lower the mower housing for the second cut. Also, instead of using the full width

of the mower housing, mulch at half the width. Clean the bottom of the mower housing. Grass and other debris

can keep the mower from working correctly. If the grass grows fast, mulch more often.

If an area needs improvement, mulch a second time.
