that do not meet American National Standards Institute certification will cause noncertification of this machine.

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 arrester muffler. It is a violation of California Public Resource Code Section 4442 to use or operate this engine on any forest–covered, brush–covered or grass–covered land. Other states or federal areas may have similar laws.

Safety

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.

12. Stop the engine before removing the grass

catcher or unclogging the chute.

13. Mow only in daylight or good artificial light.

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 belts are attached.

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.

Safety

Slope Operation

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

• 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

• Use slow speed so that you will not have to stop

while on the slope.

• Follow the manufacturer’s recommendations for

wheel weights or counterweights to improve stability.

• Use extra care with grass catchers or other

attachments. These can change the stability of the machine.

• Keep all movement on slopes slow and gradual.

Do not make sudden changes in speed or direction.

all grass can hide obstacles.

• 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

• 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.

°.

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.

• 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

near 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 or water.

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.

Safety

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.

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.

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.

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.

3. Never run a machine inside a closed area.

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.

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

Gasoline

• 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

OID THE HAZARD

• 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.

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

OID THE HAZARD

• Always place gasoline containers on the

ground away from your vehicle before filling.

• Do not fill gasoline containers inside a

vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

• When practical, r

The

Safety Interlock System

Understanding the Safety Interlock System

The safety interlock system is designed to prevent the engine from starting unless:

• You are sitting on the seat

• The parking brake is “ENGAGED”

• The power take off (PTO) is disengaged “OFF”

• The motion control levers are in neutral locked

position

The safety interlock system also is designed to stop the engine when the traction controls are moved from the locked position with the parking brake “ENGAGED” or if you rise from the seat when the PTO is “ON” engaged.

Testing the Safety Interlock System

Test the safety interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately.

1. Sitting on the seat, “ENGAGE” parking brake

and move PTO “ON”. Try starting the engine; the engine should not crank.

2. Sitting on the seat, “ENGAGE” parking brake

and move PTO “OFF”. Move either motion control lever (out of neutral locked position). Try starting the engine; the engine should not crank. Repeat for other control lever.

3. Sitting on the seat, “ENGAGE” parking brake,

move PTO switch “OFF” and move the motion control levers to neutral lock position. Now start the engine. While the engine is running, release the parking brake, engage the PTO and rise slightly from the seat; the engine should stop.

4. Sitting on the seat, “ENGAGE” parking brake,

move PTO switch “OFF” and move the motion control levers to neutral lock position. Now start the engine. While the engine is running, center either motion control and move (forward or reverse); the engine should stop.

5. Sitting on the seat, “DISENGAGE” parking

brake, move PTO switch “OFF” and move the motion control levers to neutral lock position. Try starting the engine; the engine should not crank.

Tips

for Mowing Grass

Fast Throttle Setting

For best mowing and maximum air circulation, operate the engine at “FAST.” Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.

Cutting a Lawn for the First Time

Cut grass slightly longer than normal to ensure the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than six inches tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.

Cutting Speed

To improve cut quality, use a slower ground speed in certain conditions.

Avoid Cutting Too Low

If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure that uneven turf is not cut too short.

Long Grass

If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting.

When Stopping

Cut 1/3 of the Grass Blade

It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.

Mowing Direction

Alternate mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization.

Mow at Correct Intervals

Normally, mow every four days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height; then mow again two days later at a lower height setting.

If the machine’s forward motion must be stopped while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades “ENGAGED”.

Keep the Underside of the Mower Clean

Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.

Blade Maintenance

Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary immediately with a genuine T blade.
