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 others to ride on

machine or on attachments (even with the blades

OFF). They may fall and be seriously injured.

4. DO NOT allow pre-teenage children to operate

machine.

5. ALLOW only responsible adults & teenagers with

mature judgment under close adult supervision to

operate machine.

6. DO NOT operate blades in reverse. STOP BLADES.

LOOK and SEE behind and down for children, pets

and hazards before and while backing.

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

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 the slope, DO NOT mow it. Use extra care with grass

catchers or other attachments; these affect the

handling and 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 blades OFF when traveling uphill. Use a slow speed and avoid sudden or sharp turns.

3. DO NOT operate machine back and forth across face of slopes. Operate up and down. Practice on

slopes with blades off.

4. AVOID uphill starts. If machine stops going uphill or tires lose traction, turn blades OFF and back slowly down the slope.

PROTECTION AGAINST TIPOVERS (Continued From Previous Column)

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

machine 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 operate machine on wet grass. Reduced traction could cause sliding.

11. DO NOT operate machine under any condition where traction, steering or stability is doubtful.

PREPARATION

1. Read, understand, and follow instructions and warnings in this manual and on the machine, engine and attachments. Know the controls and the proper use of the machine before starting.

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.

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

from machine. DO NOT smoke.

5. Practice operation of machine with BLADES 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.

IMPORTANT SAFETY INSTRUCTIONS

PREPARATION

(Continued From Previous Page)

7. Keep people and pets out of mowing area. Immediately STOP blades, STOP engine, and

STOP machine if anyone enters the area.

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 blades and engine quickly

in preparation for emergencies.

12. Use extra care when loading or unloading the

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 left side.

2. Start engine from operator's seat, if possible.

Make sure blades are OFF and parking brake is

set.

3. DO NOT leave machine with engine running. STOP engine, STOP blades, SET brake, and

Remove key before leaving operators position

of any reason.

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

5. STOP BLADES and ENGINE and make sure blades have stopped before removing grass

catcher or unclogging mower to prevent loss of fingers or hand.

6. Blades must be OFF except when cutting grass. Set blades in highest position when mowing over rough ground.

7. Keep hands and feet away from rotating blades

underneath deck. DO NOT place foot on ground

while BLADES are ON or machine is in motion.

8. DO NOT operate machine without entire grass catcher or guards in place. DO NOT point

discharge at people, passing cars, windows or doors.

9. Slow down before turning.

10. Watch out for traffic when near or crossing

roadways.

11. STOP engine immediately after striking an

obstruction. Inspect machine and repair damage before resuming operation.

12. Operate machine only in daylight or with good artificial light.

changes.

OPERATION

(Continued From Previous Column)

14. Exercise CAUTION when pulling loads. Limit loads to those you can safely control and attach loads to hitch plate as specified with SNAPPER attachment

instructions.

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

poison.

MAINTENANCE

1. DO NOT 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 all cotter pins are in proper position.

6. Always provide adequate ventilation when running engine. 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. DO NOT 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. DO NOT test for spark by grounding spark plug next to spark plug hole; spark plug could ignite gas

exiting engine.

Section 2 - OPERATING INSTRUCTIONS

2.7. REVERSE LOCKOUT MECHANISM

Data indicates that tragic back-over accidents occur each year. These accidents usually involve unsupervised

children. Many times these children have been given rides on the machine and have been trained to view this

potentially dangerous piece of machinery as fun rather than being taught how to avoid danger.

This riding mower has a Reverse Lockout Mechanism. This mechanism prevents the mower from being shifted into reverse with the blades running. To shift into reverse

you must first stop the blades and then shift to reverse. It is our recommendation that this mechanism remain

functional and the operator of this equipment develop the habit of never backing up with the blades running. As the Safety Instructions Indicate, DO NOT operate blades in

reverse. STOP BLADES, LOOK AND SEE BEHIND

AND DOWN for children, pets and hazards before and while backing.

We realize that this could cause a change to your previous mowing method but we encourage you to adjust

to this new system. Do not defeat the Reverse Lockout Mechanism.

If you operate your mower near roadways or use

attachments that require quicker shifting to reverse, there is an override lever provided. This lever can be

pushed and held before engaging the blades and will allow reverse operation until the blade switch is pushed in to the "OFF" position, at which time the system will

return to its Reverse Lockout mode. This feature should never be selected unless you are absolutely sure that no

children or others are present in the mowing area and that all children are away and supervised by a

responsible adult.

2.7.1. Reverse Lockout Mechanism Override

1. Stop machine. Stop blades.

2. Depress and hold Override Lever.

3. Pull blade switch "OUT" to engage blade.

4. Release Override Lever

LOOK and SEE behind and down for children, and hazards before and while backing.

IMPORTANT! DO NOT use the Reverse Lockout Mechanism Override as the normal operating mode. To

return to the Reverse Lockout Mechanism mode, disengage (STOP) blades by pushing blade switch in to

the "OFF" position. The Override will reset to Reverse Lockout.

2.7.2. Check the Reverse Lockout Mechanism

Before each use, check the Reverse Lockout Mechanism for proper function. The following

procedure requires the operation of the engine and blades. Before proceeding, Read, Understand, and

Follow all Safety Instructions and Warnings in this manual and on the machine.

1. Complete Pre-Start Checklist.

2. Move machine to clear open area. DO NOT allow children or others in area.

3. Start engine.

4. Pull blade switch "OUT" to engage blades.

5. Reverse Lockout Mechanism must prevent

speed control lever from going into reverse.

Ik WARNING

DO NOT operate machine if Reverse Lockout[ Mechanism is not functioning properly. Contact your [

SNAPPER dealer immediately for assistance. [

DANGER

LOOK and SEE behind and down for children, pets

and hazards before and while backing.

BLADES must be turned off before backing machine. DO NOT allow children on machine (even with

blades off) or in yard when mowing.
