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

3.11 ADJUSTING FIXED DECK ATTACHMENT

The Mower Deck has four different positions for attaching it to the power unit. The lowest setting

provides a cutting height range from 1 1/2" to 2 1/2", the middle low cut from 2 1/4" to 3 1t4", the middle high cut

from 3" to 4", and the highest cut from 3 3/4" to 4 3/4".

Make sure the Spacers on the Caster Wheels are moved UP or DOWN as shown below to correspond

with the bolt positions to keep the Mower Deck level. Once a desired cutting height is reached, attach the

Mower Deck to the power unit by installing 3 bolts on

each side in selected height of cut holes. Tighten the

bolts from 70 to 80 foot pounds torque.

3.12 CUTTING HEIGHT ADJUSTMENTS FOR

ADJUSTABLE DECK ATTACHMENTS

The Mower Deck should be mounted in the lowest

holes (low cut) on the power unit.

To adjust height of cut, turn both Cranks (located on

right hand and left hand side of deck) clockwise to raise the Mower Deck and counter-clockwise to

lower the Mower Deck. Observe the height of cut decal located on the side of the Mower Deck

mounting plates and move the height of cut pointers in the same de-sired position. See Figure 3.17.

If pointers are in the correct position and you still have an uneven cut, follow the instructions as listed

below to correct the problem:

A. Rotate outer Blades to point toward the sides of

the Mower Deck (make sure Mower is on level surface).

B. Measure the distance from Blade tip to the

ground. Measure both outside Blades. This measurement should be the same as what the

height of cut pointer reads on both sides.

C. If measurement is NOT the same, then bend both

height of cut pointers UP or DOWN to read the same as Blade tip measurements.

WARNING

Shield the positive terminal with terminal cover

located on battery harness. This prevents metal from

touching the positive terminal, which could cause sparks. Cables must be connected to battery terminals in the proper position. RED (Positive) cable

must go to the ( + ) terminal. BLACK (Negative) cable must go to the ( - ) terminal.

3.13 BATTERY REMOVAL

1. Remove battery retainer.

2. Slide terminal cover away from positive terminal.

3. Observe and note cable positions on battery

4. Disconnect cables from battery terminals, disconnecting BLACK (Negative) cable first, then

disconnect RED (Positive) last. Retain mounting bolts and nuts.

3.14 BATTERY INSTALLATION

1. Position battery into battery compartment.

2. Connect cables to battery terminals. Connect RED (Positive) cable first. Connect BLACK (Negative)

cable last.

3. Reinstall battery retainer and positive terminal cover.

4. With cell caps removed, connect battery charger to battery terminals. RED to positive (+) terminal and BLACK to negative (-)terminal.

5. Slow charge battery at 1 amp for 10 hours. An alternative fast charge should be no more than 2.5

amps for four hours.

6. If battery will not accept charge or is partially charged after 10 hours of charging at 1 amp, replace with new battery.

WARNING

The electrolyte (acid) produces a highly explosive gas. Keep all sparks, flame and fire away from area

when charging battery or when handling electrolyte

or battery. Electrolyte (acid) is a highly corrosive liquid. Wear eye protection. Wash affected areas immediately after having eye or skin contact with electrolyte (acid). Battery acid is corrosive. Rinse empty acid containers with water and mutilate before discarding. If acid is spilled on battery, bench, or clothing, etc., Flush with clear water and neutralize

with baking soda.

3.15 BATTERY SERVICE

1. Remove battery.

2. Place battery in a well ventilated area on a level surface.

3.16 BATTERY TESTING

There are two types of battery tests: Unloaded and

Loaded. The unloaded test is the procedure that will be

discussed, it's the simplest and most commonly used. An unloaded test is made on a battery without

discharging current. To perform unloaded testing, check charge condition using either a hydrometer or voltmeter.

1. Using a voltmeter, voltage readings appear instantly to show the state of charge. Remember to hook the

positive lead to the battery_s positive terminal, and the negative Iead to the negative terminal.

2. A hydrometer measures the specific gravity of each cell. The specific gravity tells the degree of charge;

generally, a specific gravity of about 1.265 to 1.280 indicates full charge. A reading of 1.230 to 1.260 indicates the battery should be charged before

testing. The chart on the next page shows the charge level as measured by syringe float hydrometer, digital voltmeter and five ball hydrometer.

Dirt can also be introduced

into an engine In dirty fuel

from a contaminated container. Always use clean

fresh fuel from a clean

container to guard against dirt, sludge and water

contamination.

Be aware that fuel breaks down In storage and forms

will block carburetor pass- ages. Never use fuel more

than 3 months old. Drain tank then run the engine out of fuel before storing during

the off-season.

An engine must also have proper lubrication. All engines use some oil On 4-cycle engines,

CHECK OIL LEVEL BEFORE EACH START-UP.

Wipe area clean around the oll check plug or

dipstick opening to keep dirt from falling Into

the engine when checking the oil Always check with the machine on a level surface.

On engines with dipstick, keep the level up to, but not over, the FULL mark. When adding oil,

allow time for all of the oll to flow down the fill tube to prevent afalse full reading when the

level could actually be low and result Inengine

damage.

PRIMARY MAINTENANCE

On 4-cyle engines with an oll level plug,

don't be fooled Into thinking the engine has sufficient lubricating oll If you can see "some" oll In the opening - the level should always be

brought up to the point of € top of the fill hole.

Change all at regular Intervals using s a high

quality oil such as Snapper's small engine formulated 4-cycle engine oil Refer to the

engine owner's manual for oil details.

On 2-cycle engines, lubrication must be

provided by an exact mixture of gasoline and 2-cycle sir-cooled engine oil A 2-cycle

engine that Is mistakenly run on strelght

gasoline will be reined in less than 5 mlnutasl If you keep straight gasoline In

addition to pre-mlxed 2-cycle engine fuel, be sure the containers are clearly marked

to avoid mix-up.
