Engine Exhaust, some of its constituents, and certain vehicle components contain or emit

chemicals known to the State of California to cause cancer and birth defects or other repro-

ductive harm.

Battery posts, terminals and related accesso- ries contain lead and lead compounds, chemi-

cals known to the State of California to cause cancer and birth defects or other reproductive

harm. WASH HANDS AFTER HANDLING.

NOTE: This unit is equipped with an internal combustion engine

and must not be used on or near any unimproved forest-covered, brush-covered or grass-covered land unless the engine's exhaust

system is equipped with a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it must be

maintained in effective working order by the operator.

In the State of California, the above is required by law (Section

4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. See a

Sears Service Center for a spark arrester for the muffler.

In some areas, local law requires the use of a resistor spark plug

to control the ignition signals. See a Sears Service Center for a resistor spark plug for the engine.

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

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.

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.

Mow up 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.

12. Mow only in daylight or good artificial light. DO NOT

13. Do not operate the machine while under the influence of alcohol 1. or drugs or when very tired.

14. Watch for traffic when operating near or crossing roadways. 2.

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.

erate this machine.

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

F-040601C

Do not turn on slopes unless absolutely necessary, then only

turn slowly and gradually downhill, if possible. Do not mow drop-off's, ditches or embankments. A wheel over

the edge or an edge caving in could cause a sudden overturn and an injury or death.

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

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

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

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.

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 heaten

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 ifyou 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

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. Ifthe 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

attachment, do not operate the unit on a slope that is greater than 10 degrees.

F-040601C 17

OPERATING TIPS

OPERATION

Check the attachment clutch for correct adjustment. For the blade(s} to disengage correctly the adjustment must be coF

tact.

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 inn

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. Forthe 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 notdischarge 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 isa more even discharge of cut grass.

When you mow large areas, start by turning to theright so that the cut grass will discharge away from shrubs fences, drive n ways etc. After one or two rounds, mow in the opposite direc_

tion making left turns until finished (Figure 13).

9. If the grass is very high cut two times to decrease the load on

theengine Firstcutwiththemower housinginthehighestpesF

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. I1"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.

MULCHING TIPS

When you use a mulcher attachment, the grass is cut intovery small pieces These small pieces will quickly break down. Because the nutrients are returned to the soil, the lawn will need lessfertilizer. 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

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.

F-0406010 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 thebottom of the mower housing. Grass and other debds can keep the mower from working correctly

If the grass grows fast, mulch more often.

If an area needs improvement, mulch a second time.
