Thank you for buying a SNAPPER Product! Before operating your PRO WALK BEHIND, read this manual carefully and pay particular attention to the "IMPORTANT SAFETY INSTRUCTIONS" on Pages 2&3. 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!

SNAPPERMcDonough,GA,, 30253 U.S.A.

MANUAL No. 4-3799 (REV. 2, 5/17/99)

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 (even with the blade OFF).

3. DO NOT allow children or other passengers to ride on machine or on attachments (even with the

blade OFF). They may fall and be seriously injured.

4. DO NOT allow pre-teenage children to operate

machine.

5. ALLOW only adults or responsible teenagers with mature judgment under close adult supervision to

operate machine.

6. BE SURE the area is clear of others before mowing and turn machine OFF if anyone enters

the area.

7. DO NOT mow in reverse unless absolutely necessary. LOOK BEHIND and down for small

children before and when backing.

8. USE EXTRA CARE when approaching blind

corners, shrubs, trees, or other objects that may obscure vision.

PROTECTION AGAINST TIPOVERS (Continued From Previous Column)

4. AVOID uphill starts. If machine stops going uphill

or tires lose traction, turn blade OFF and back slowly down the slope.

5. STAY ALERT for holes and other hidden hazards. Tall grass can hide obstacles. Keep away from

ditches, washouts, culverts, fences and

protruding objects.

6. KEEP A SAFE DISTANCE (at least 3 feet) away from edge of ditches and other drop offs. The

mower could turn over if an edge caves in.

7. Always begin forward motion slowly and with caution.

8. Use weights or a weighted load carrier in accordance with instructions supplied with a grass catcher. DO

NOT operate machine on slopes exceeding 10

degrees (18% grade) when equipped with grass catcher.

9. DO NOT put your foot on the ground to try to stabilize the machine.

10. DO NOT mow on wet grass. Reduced traction could cause sliding.

11. DO NOT mow under any condition where traction, steering or stability is doubtful without first test driving over the terrain with blade OFF.

12. Operator Protective Structures are available for this machine through your local Snapper dealer.

PROTECTION AGAINST TIPOVERS

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. Use extra care with grass catchers

or other attachments; these can change the stability of the machine.

1. DO NOT operate machine on slopes exceeding 15 degrees (27% grade).

2. Exercise EXTREME CAUTION on slopes above 10

degrees (18% grade). Turn blade OFF when traveling uphill. Use first speed and avoid sudden or sharp turns.

3. DO NOT mow back and forth across face of

slopes. Mow up and down.

PREPARATION

1. Read this manual, get to know where all controls are located and practice how to use them before

starting for the first time, and at the beginning of each season. Read and follow Warnings and

Instructions on engine and machine. Read and

follow operator's manual and instructions furnished with attachments.

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

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.

IMPORTANT SAFETY INSTRUCTIONS

PREPARATION

(Continued From Previous Page)

4. Handle fuel with extra care. Fuels are flammable

and vapors are explosive. Use only an approved

fuel container. Never remove fuel cap or add fuel with engine running. Add fuel outdoors

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

5. Practice operation of machine with BLADE OFF to learn controls and develop skills.

6. 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.

7. Keep people and pets a safe distance from

machine.

8. Check shields, deflectors, switches, blade controls and other safety devices frequently for

proper operation and location.

9. Make sure all safety decals are clearly legible.

Replace if damaged.

10. Protect yourself when mowing and wear safety

glasses, long pants and substantial footwear.

11. Know how to STOP blade and engine quickly in

preparation for emergencies.

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

13. 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 worn spots.

OPERATION

1. Mount and dismount machine from leftside.

2. Start engine from operator's seat, if possible. Make sure blade is OFF and parking brake isset.

3. STOP blade, STOP engine, set parking brake and

remove key when leaving machine.

4. DO NOT operate machine unless properly seated with feet on feet rests or pedal(s).

5. STOP BLADE and ENGINE and make sure blade

has stopped before removing grass catcher or unclogging mower to prevent loss of fingers or

hand.

6. Blade must be OFF except when cutting grass. Set

blade in highest position when mowing over rough

ground.

7. Keep hands and feet away from rotating blade

underneath deck. NEVER place foot on ground

while BLADE isON or machine is in motion.

8. Deflector or entire grass catcher must be in place.

NEVER point discharge at people, passing cars,

windows or doors.

9. Slow down before turning.

10. Watch out for traffic when near or crossing

roadways.

OPERATION (Continued From Previous Column)

11. STOP engine immediately after striking an obstruction. Inspect machine and repair damage before resuming operation.

12. Mow only in daylight or with good artificial light.

13. Move motion control levers SLOWLY to maintain control during speed and directional

changes.

14. Exercise CAUTION when pulling loads. DO NOT pull loads greater than 300 pounds. Avoid jack

knifing. DO NOT turn sharply.

MAINTENANCE

1. Never store machine 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 the reach of children in a well ventilated, unoccupied building.

2. Keep 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. Check brakes frequently; adjust, repair or replace as needed.

5. Keep all bolts, nuts and screws properly tight. Check that allcotter pins are in proper position.

6. Always provide adequate ventilation when running engine indoors. Exhaust gases contain carbon monoxide, an odorless and deadly poison.

7. Disconnect negative (black) cable from battery before performing maintenance or service. Cranking engine could cause injury.

8. Never work under machine without safety blocks.

9. Service engine and make adjustments only when engine is stopped. Remove spark plug wire(s) from

spark plug(s) and secure wire(s) away from spark plug(s).

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

11. Lubricate machine at intervals specified in manual to prevent controls from binding.

12. Mower blades are sharp and can cut. Wrap the blades or wear heavy leather gloves and use CAUTION when handling them.

13. NEVER test for spark by grounding spark plug next to spark plug hole; spark plug could ignite gas

exiting engine.

14. Have machine serviced by an authorized SNAPPER dealer at least once a year and have the dealer install any new safety devices.

15. Use only genuine SNAPPER replacement parts to assure that original standards are maintained.
