Safety

Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death.

Safe

This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

Operating Practices

POTENTIAL HAZARD

• Engine exhaust contains carbon monoxide,

which is an odorless, deadly poison.

WHAT CAN HAPPEN

• Carbon monoxide can kill you and is also

known to the State of California to cause birth defects.

HOW TO AV

OID THE HAZARD

• Do not run engine indoors or in an enclosed

area.

This product is designed for cutting and recycling grass or, when equipped with a grass bagger, for catching cut grass. Any use for purposes other than these could prove dangerous to user and bystanders.

Note: This engine is NOT equipped with a

spark arrestor muffler. Use or operation of this mower in the State of California on any forest-covered or unimproved grass-covered land, without an approved spark arrester muffler, is a violation of the law. Other states may have similar laws.

General Operation

1. Read, understand, and follow all instructions in

the operator’s manual and on the machine before starting.

2. Allow only responsible adults who are familiar

with the instructions 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. 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 catcher or the guard in place.

8. Slow down before turning. Sharp turns on any

terrain may cause loss of control.

9. Never leave a running machine unattended.

Always turn off blades, set parking brake, stop engine, and remove key before dismounting.

10. Turn off blades when not mowing.

11. Keep hands, feet, hair and loose clothing away

from attachment discharge area, underside of mower and any moving parts while engine is running.

12. Stop the engine before removing the grass

catcher or unclogging the chute.

13. Mow only in daylight or good artificial light.

Page 5

Safety

14. Do not operate the machine while under the

influence of alcohol or drugs.

15. Watch for traffic when operating near or crossing

roadways.

16. Use extra care when loading or unloading the

machine onto a trailer or truck.

17. Do not touch equipment or attachment parts

which may be hot from operation. Allow to cool before attempting to maintain, adjust or service.

18. Before operating a machine with ROPS (roll

over protection) be certain the seat belt retainers are attached to prevent the seat from pivoting forward.

Slope Operation

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

• Keep all movement on slopes slow and gradual.

Do not make sudden changes in speed or direction.

• Avoid starting or stopping on a slope. If tires

lose traction, disengage the blades and proceed slowly straight down the slope.

• When operating machine on slopes, banks or

drop offs, always have ROPS (roll over protection) installed.

• When operating a machine with ROPS (roll over

protection) always use seat belt.

• Be certain that the seat belt can be released

quickly if the machine is driven or rolls into ponds of water.

• Check carefully for overhead clearances (i.e.

branches, doorways, electrical wires) before driving under any objects and do not contact them.

DO NOT

• Do not operate machine on hillsides or slopes

exceeding 15

°.

• Mow up and down slopes greater than 5°, not

across.

• Mow downhill only on slopes above 10°, never

mow uphill. If a steep slope must be ascended, back up the hill, and drive forward down the hill, keeping the machine in gear.

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

from the mowing area. Watch for holes, ruts or bumps, as uneven terrain could overturn the machine. T

all grass can hide obstacles.

• Use slow speed. Choose a low gear so that you

will not have to stop or shift while on the slope.

• Follow the manufacturer’s recommendations for

wheel weight or counterweights to improve stability.

• Use extra care with grass catchers or other

attachments. These can change the stability of the machine.

• Avoid turning on slopes. If you must turn, turn

slowly and gradually downhill, if possible.

• Do not mow near drop-offs, ditches, or

embankments. The machine could suddenly turn over if a wheel goes over the edge of a cliff or ditch, or if an edge caves in.

• Do not mow on wet grass. Reduced traction

could cause sliding.

• Do not try to stabilize the machine by putting

your foot on the ground.

• Do not use a grass catcher on steep slopes.

Heavy grass bags could cause loss of control or overturn the machine.

Safety

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. The following requirements must be followed to prevent injury to children.

1. Keep children out of the mowing area and under

the watchful care of another responsible adult.

2. Be alert and turn the machine off if children

enter the area.

3. Before and while backing, look behind and down

for small children.

4. Never carry children. They may fall off and be

seriously injured or interfere with safe machine operation.

5. Never allow children to operate the machine.

6. Use extra care when approaching blind corners,

shrubs, trees, the end of a fence or other objects that may obscure vision.

4. Keep nuts and bolts tight, especially the blade

attachment bolts. Keep equipment in good condition.

5. Never tamper with safety devices. Check safety

systems for proper operation before each use.

6. Keep the machine free of grass, leaves, or other

debris build-up. Clean up oil or fuel spillage. Allow the machine to cool before storing.

7. Stop and inspect the equipment if you strike an

object. Repair, if necessary, before restarting.

8. 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.

9. Mower blades are sharp and can cut. Wrap the

blade(s) or wear gloves, and use extra caution when servicing them.

10. Use only genuine replacement parts to ensure

that original standards are maintained.

Service

1. Stop the engine and disconnect spark plug

wire(s) before performing any service, repairs, maintenance or adjustments.

2. Use extra care when handling gasoline and other

fuels. They are flammable and vapors are explosive.

A. Use only an approved container. B. Never remove the gas cap or add fuel when

the engine is running. Allow the engine to

cool before refueling. Do not smoke. C. Never refuel the machine indoors. D. Never store the machine or fuel container

inside where there is an open flame, such as

near a water heater or furnace.

3. Never run a machine inside a closed area.

11. Check brake operation frequently. Adjust and

service as required.

12. Battery acid is poisonous and can cause burns.

Avoid contact with skin, eyes and clothing. Protect your face, eyes and clothing when working with a battery.

13. Battery gases can explode. Keep cigarettes,

sparks and flames away from battery.

14. Hydraulic fluid escaping under pressure can

penetrate the skin and cause injury. Use cardboard or paper to find hydraulic leaks.

15. Never modify ROPS (roll over protection)

frames or structures because they are specifically designed, sized, located and tested for injury reduction. If a rollover occurs, a modified ROPS will not provide adequate protection.

Gasoline and Oil

Recommended

Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available.

IMPORTANT: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

POTENTIAL HAZARD

• In certain conditions gasoline is extremely

flammable and highly explosive.

WHAT CAN HAPPEN

• A fire or explosion from gasoline can burn

you, others, and cause property damage.

HOW TO AV

• Use a funnel and fill the fuel tank outdoors,

in an open area, when the engine is cold. Wipe up any gasoline that spills.

• Do not fill the fuel tank completely full.

Add gasoline to the fuel tank until the level is 1/4” to 1/2” (6 mm to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

• Never smoke when handling gasoline, and

stay away from an open flame or where gasoline fumes may be ignited by a spark.

• Store gasoline in an approved container

and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.

OID THE HAZARD

Gasoline

Stabilizer/Conditioner

Add the correct amount of gas stabilizer/conditioner to the gas. Using a stabilizer/conditioner in the machine:

• Keeps gasoline fresh during storage

• Cleans the engine while it runs

• Eliminates gum-like buildup in the fuel system,

which causes hard starting

IMPORTANT: Never use fuel additives containing methanol or ethanol.

from the fuel tank (step 10) or add a fuel stabilizer/conditioner additive to a full tank of gasoline (step A).

10. Drain gasoline from the fuel tank; refer to Fuel

Tank, page 27. After fuel is drained, start the engine and let it idle until all gasoline is consumed and the engine stops. This eliminates gum-like buildup in the fuel system, which causes hard starting. Try to start the engine two more times to assure that no gasoline is in the fuel system.

A. Add the correct amount of a fuel

stabilizer/conditioner or an isopropyl-based stabilizer/conditioner to a full tank of gasoline. Operate engine for 5 minutes to distribute stabilizer/conditioner throughout fuel system.

Note: Stabilizer/conditioners normally

preserve gasoline for six to eight months.

11. Check and tighten all bolts, nuts, and screws.

Repair or replace any part that is damaged or defective.

12. Paint all scratched or bare metal surfaces. Paint

is available from your Authorized Service Dealer.

13. Store the machine in a clean, dry garage or

storage area. Remove the key from the ignition switch and keep it in a memorable place. Cover the machine to protect it and keep it clean.

8. Check the tire pressure; refer to Tire Pressure,

page 26.
