SAFETY RU LES

SAFETY RULES

Safe Operation Practices for Ride-on Mowers

WARNING: 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 in the Instruction Book, on the machine, the engine and with any attachments be- fore starting.

2. Only allow responsible adults, who are familiar with the instruc- tions, to operate the machine.

3. Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade.

4. Be sure the area is clear of other people before mowing. Stop the machine if anyone enters the area.

5. Never carry passengers.

6. Turn off power to the blades or any attachments before backing up. Do not mow in reverse unless absolutely necessary. Always

look down and behind before and while backing.

7. Be aware of the mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire

grass bagger or the mower guard in place.

8. Slow down before turning.

9. Never leave a machine unattended with the engine running. Al- ways turn off the blade(s), set the parking brake, stop the en-

gine and remove the key before dismounting.

10. Turn off power to attachment(s) when transporting or not in use. Turn off the blade(s) when not mowing.

11. Stop the engine before removing the grass bagger or unclog- ging the chute.

12. Mow only in daylight or good artificial light.

13. Do not operate the machine while under the influence of alcohol or drugs or when very tired.

14. Watch for traffic when operating near or crossing roadways.

15. Use extra caution when loading or unloading the machine into a trailer or truck.

16. Disengage all attachment clutches and shift into Neutral before attempting to start the engine.

17. 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.

18. 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.

19. 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.

20. Do not use this machine ff you are mentally or physically unable to operate this machine safely.

F-030614L

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. It 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.

MOWup and down slopes, not across.

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

Watch for holes, ruts or bumps. Uneven terrain could overturn

the machine. Tall grass can hide obstacles.

Follow the manufacturer's recommendations for wheel weights

or counterweights to improve stability.

Use extra care with grass baggers or other attachments, they

can change the stability of the machine.

Keep all movement on the slopes slow and gradual. Do not

make sudden changes in speed or direction.

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 drolm_ffs, 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 RU LES

Never carry children or any passengers, even with the blades 6. off. They may fall off and be seriously injured or interfere with the safe operation of the machine. 7.

Never allow children to operate the machine, instruct children in the potential dangers of the machine.

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

IV. Service

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 refuel-

ing. Do not smoke. c. Never refuel the machine indoors. d. Never store the machine with fuel in the tank or fuel contain-

er inside where there is an open flame, such as a water heater.

Never start or run the engine inside a closed area.

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.

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.

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.

9. 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.

RESPONSIBILITY OF THE OWNER

Environmental Awareness

PREPARATION

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.

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

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.

CHECK THE TIRES

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

(PSi) is as follows. Semi-pneumatic front tires do not require air.

Front Tires 22 PSI (1.5 BAR) Rear Tires 14 PSI (1 BAR)

IMPORTANT! BEFORE YOU START MOWING

Check the engine oil. Fill the fuel tank with gasoline. Check the level of the mower housing. Check the air pressure of the tires. Make sure the battery cables are attached.

10.

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.

,_ WARNING: For better control of the unit, always

select a safe speed.

HOW TO OPERATE THE UNIT ON HILLS

WARNING: Do not ride up or down slopes that are too

steep to back straight up. Never ride the unit across

a slope. See the "Slope Guide" in the back of this book for information on how to check slopes.

1. Before you ride up or down a hill, move the speed control lever to a slow speed.

2. Do not stop or change speed settings on a hill. Ifyou must stop, quickly push the clutch/brake pedal forward and set the parking brake.

ATTACHMENTS

This unit can use many different attachments. It can pull attachments like a lawn sweeper, a lawn aerator, a hopper spreader, or a small trailer. This unit cannot use attachments that engage the ground like a plow, a disk harrow, or a cultivator. For all pull-behind attachments or trailers, the maximum gross weight is 200 pounds. Gross weight is the weight of the attachment or trailer and any load that might be on or in it.

TO start again, make sure the speed controllever is in a slow speed. Move the throttle control to the SLOW position. Slowly

release the pedal.

If you must stop or start on a hill, always have enough space for the unit to roll when you release the brake and engage the clutch.

Be very careful when you change directions on a hill. When on a slope or in a turn on a hill, move the throttle control to the

SLOW position to help prevent an accident.

WARNING: To avoid possible serious injury, do not

mow a slope that is greater than 15 degrees. If the rid- ing mower is used with a pull-behind or rear-mounted attachment, do not operate the unit on a slope that is greater than 10 degrees.

_030614L 17

OPERATING TIPS

OPERATION

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.

tf 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

1. 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.

2. For the mower housing to cut level, make sure the tires have the correct amount of air pressure (PSI).

3. 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.

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

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

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

7. 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 will 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 12).

9. tf 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.

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

position.

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

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

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

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

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

speed.

12. For better cutting performance and a quality cut, mow in a slow

forward speed.

13. 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.

Figure12

MULCHING TIPS

When you use a mulcher attachment, the grass is cut into very small 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, tf ground speed is too fast, the grass will

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.

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

_030614L 18

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.
