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 w hen 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 object s that may obscure vision.

SLOPE OPERATION

1. Slo pes 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 crass 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. Dat a indicates that operators age 60 an d 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 approv ed 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 in jury 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.

IMPORTANT SAFETY INSTRUCTIONS

OPERATION

1. DO NOT put hands or feet near or under rotating parts. Keep clear of discharge area wh ile en gine is running.

2. STOP engine when crossing g ravel driv es, w alks, 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. In spect 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.

9. DO NOT leave the machine with the engine running. STOP BLADE and STOP ENGINE before leaving the operators position for any r eason.

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 en gine 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 co tter 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 b ag assemb ly frequent ly for w ear o r deterioration to avoid thrown objects and exposure to moving parts. Replace w ith new bag if loose seams or tears are evident. Replace slider or bag adapter if broken or cracked.

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 next to spark plug hole; spark plug could ignite gas exiting engine.

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

Section 3 - MAINTENANCE

3.1 INTRODUCTION

To retain the quality of the mower, use genuine SNAPPER replacement parts only. Contact a local SNAPPER dealer for parts and ser vice assis tance. For the correct part or information for a particular mower, always mention model and serial number.

3.2 SERVICE - AFTER FIRST 5 HOURS

3.2.1. CHANGE ENGINE OIL

WARNING

(ROBIN ENGINES)

1. Refer to Engine Manual for proper oil

specifications and procedures.

2. For simplest/cleanest oil change, loosen lower handle wing nuts and stand mower up on lower handle as shown in Figure 3.1. Drain oil through dipstick tube into a container.

IMPORTANT: DO NOT tip machine with carburetor or spark plug down. Oil f rom crank case will saturate the air filter and cause the engine to be hard to s tart or not start at all. If contamination does occ ur, the air filter will have to be replaced.

(KAWASAKI ENGINES)

1. The items needed to perform oil change are:

cloth rags, (1) 24” long plastic hose and ( 1) 2 quart shallow pan.

2. Tilt mower on its left wheels and place blocks under the right wheels. See Figure 3.1.

3. Attach plastic hose over end of nipple on oil drain plug and allow opposite end to lay in pan.

4. Using a wrench, turn oil drain plug counter clockwise until oil drains freely from engine into pan.

NOTE: Check specific model engine owner’s manual for changing engine oil procedure.
