IMPORTANT SAFETY INSTRUCTIONS

WARNING: This powerf ul cutting machine is capab le of amputating hand s and feet and can throw objects that can cause injury and damage! Failure to comply with the follow ing SAFETY instru ctions could resu lt 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 occu r 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 operat e blad es in reverse. ST OP BLADES. LOOK and SEE behind an d 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 slop es 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 su pplied 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 mowerrelated 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, limb s and other objects that could cau se 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 dev ices frequently for proper operation and location.

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

10. Protect yourself w hen 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 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 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 wh en cutting grass. Set blades in highest position when mowing over rough ground.

7. Keep hands an d 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.

13. Move joystick (if equipped) SLOWLY to maintain control during speed and directional 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 o ut 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. Mow er 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.

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.
