Thank you for buying a SNAPPER Product! Before operating your Walk Behind, read this manual carefully and pay particular attention to the "IMPORTANT SAFETY INSTRUCTIONS" on Pages 2, 3, & 4. Remember that all power

equipment can be dangerous if used improperly. Also keep in mind that SAFETY requires careful use in accordance

with the operating instructions and common sense.

MANUAL No. 7-4349 (Rev. 1, 2/3/03)

IMPORTANT SAFETY INSTRUCTIONS

WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects that can cause injury and damage! Failure to comply with the following SAFETY instructions could result in serious

injury or death to the operator or other persons. The owner of the machine must understand these instructions and must allow only persons who understand these instructions to operate machine. Each person operating the machine must be of sound mind and body and must not be under the influence of any substance, which might

impair vision, dexterity or judgment. If you have any questions pertaining to your machine which your dealer cannot answer to your satisfaction, call or write the Customer Service Department at SNAPPER, McDonough, Georgia 30253. Phone: (1-800-935-2967).

PROTECTION FOR 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.

1. KEEP children out of the mowing area and under the watchful care of a responsible adult.

2. DO NOT allow children in yard when machine is

operated and turn machine OFF if anyone enters the area.

3. DO NOT allow pre-teenage children to operate machine.

4. ALLOW only responsible adults & teenagers with mature judgment under close adult supervision to operate machine.

5. DO NOT pull mower backwards unless absolutely necessary. LOOK and SEE behind

and down for children, pets and hazards before and while backing.

6. USE EXTRA CARE when approaching blind corners, shrubs, trees, or other objects that may

obscure vision.

SLOPE OPERATION

1. Slopes are a major factor related to slip and fall

accidents, which can result in severe injury. All slopes require extra caution. If you feel uneasy on a slope, DO NOT mow it.

2. Mow across slopes, never up-and-down.

Exercise extreme CAUTION when changing

directions on slopes. DO NOT mow steep slopes or other areas where stability or traction

is in doubt.

3. Use extra care with grass catchers or other attachments; these affect the handling and the stability of the machine.

PREPARATION

1. Read, understand, and follow instructions and

warnings in this manual and on the mower, engine and attachments. Know the controls and the proper use of the mower before starting.

2. Only mature, responsible persons shall operate the machine and only after proper instruction.

PREPARATION

(Continued From Previous Column)

3. Data indicates that operators age 60 and above, are involved in a large percentage of mower- related injuries. These operators should evaluate their ability to operate the mower safely enough to protect themselves and others from serious injury.

4. Handle fuel with extra care. Fuels are flammable and vapors are explosive. Use only an approved

fuel container. DO NOT remove fuel cap or add fuel with engine running. Add fuel outdoors

only with engine stopped and cool. Clean spilled fuel and oil from machine. DO NOT

smoke.

5. Check the area to be mowed and remove all objects such as toys, wire, rocks, limbs and

other objects that could cause injury if thrown by blade or interfere with mowing. Also note the

location of holes, stumps, and other possible hazards.

6. Keep people and pets out of the mowing area. Immediately, STOP Blade, Stop engine and Stop mower if anyone enters the area.

7. Check shields, deflectors, switches, blade controls and other safety devices frequently for proper operation and location.

8. Make sure all safety decals are clearly legible. Replace if damaged.

9. Protect yourself when mowing and wear safety glasses, long pants and substantial footwear.

DO NOT mow barefooted or with sandals.

10. Know how to STOP blade and engine quickly in preparation for emergencies.

11. Use extra care when loading or unloading the machine into a trailer or truck.

12. Check grass catcher components frequently for signs of wear or deterioration and replace as needed to prevent injury from thrown objects going through weak or torn spots.

SAFE HANDLING OF GASOLINE

To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive

1. Extinguish all cigarettes, cigars, pipes and other sources of ignition.

2. Use only an approved fuel container.

IMPORTANT SAFETY INSTRUCTIONS

SAFE HANDLING OF GASOLINE

(Continued From Previous Page)

3. DO NOT remove fuel cap or add fuel with the

engine running. Allow the engine to cool before

refueling.

4. DO NOT refuel the machine indoors.

5. DO NOT store the machine or fuel container inside where there is an open flame, spark or

pilot light such as on a water heater or other

appliances.

6. DO NOT fill fuel containers inside a vehicle or

on a truck or trailer bed with a plastic liner. Always place the containers on the ground away from the vehicle before filling.

7. Remove gas-powered equipment from the

vehicle or trailer and refuel it on the ground. If this is not possible, then refuel equipment using a portable container, rather than a gasoline dispenser nozzle.

8. DO NOT start gas powered equipment in

enclosed vehicles or trailers.

9. Keep the nozzle in contact with the rim of the

fuel tank or container opening at all times until fueling is complete. DO NOT use a nozzle lock-

open device

10. If fuel is spilled on clothing, change clothing

immediately.

11. Never overfill a fuel tank. Replace fuel cap and

tighten securely.

OPERATION

1. DO NOT put hands or feet near or under rotating

parts. Keep clear of discharge area while engine is running.

2. STOP engine when crossing gravel drives,

walks, or roads, and under any conditions where thrown objects might be a hazard.

3. Mow only in daylight or good artificial light.

4. DO NOT operate mower while under the influence of alcohol or drugs.

5. After striking a foreign object or if mower

vibrates abnormally, STOP the engine, disconnect and secure spark plug wire. Inspect

the mower for any damage and repair the damage.

6. DO NOT mow near drop offs, ditches or

embankments. Operator could lose footing or balance.

7. STAY ALERT for holes and other hidden hazards. Tall grass can hide obstacles. Keep

away from ditches, washouts, culverts, fences and protruding objects.

8. DO NOT mow on wet grass. Always be sure of

your footing. Keep a firm hold on the handle and walk, never run. Slipping could cause

injury.

OPERATION

(Continued From Previous Column)

9. DO NOT leave the machine with the engine

running. STOP BLADE and STOP ENGINE before leaving the operators position for any

reason.

10. Before cleaning, repairing or inspecting make

certain engine, blade and all moving parts have STOPPED. Disconnect and secure spark plug wire away from plug to prevent accidental starting.

11. STOP engine and wait until the blade comes to

complete STOP before removing grass bag and/or clearing grass.

12. DO NOT operate mower without the entire grass catcher or guards in place. DO NOT point discharge at people, passing cars, windows or

doors.

13. Slow down before turning.

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

15. DO NOT operate engine in enclosed areas. Engine exhaust gases contain carbon monoxide, a deadly poison.

MAINTENANCE AND STORAGE

1. DO NOT store mower or fuel container inside where fumes may reach an open flame, spark or

pilot light such as in a water heater, furnace, clothes dryer or other gas appliance. Allow

engine to cool before storing machine in an enclosure. Store fuel container out of reach of

children in a well ventilated, unoccupied building.

2. Keep mower and engine free of grass, leaves or excess grease to reduce fire hazard and engine overheating.

3. When draining fuel tank, drain fuel into an approved container outdoors and away from

open flame.

4. Keep all bolts, especially blade bolts, nuts and screws properly tight. Check that all cotter pins are in proper position.

5. Always provide adequate ventilation when running engine. Engine exhaust gases contain carbon monoxide, a deadly poison.

6. Service engine and make adjustments only when engine is stopped. Removed spark plug wire from spark plug and secure wire away from spark plug to prevent accidental starting.

7. DO NOT change engine governor speed settings or overspeed engine.

8. Check grass bag assembly frequently for wear or deterioration to avoid thrown objects and exposure to moving parts. Replace with new bag if loose seams or tears are evident. Replace

slider or bag adapter if broken or cracked.

IMPORTANT SAFETY INSTRUCTIONS

MAINTENANCE AND STORAGE

(Continued From Previous Page)

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

blades or wear heavy leather gloves and use CAUTION when handling them.

10. DO NOT test for spark by grounding spark plug
