IMPORTANT SAFETY INSTRUCTIONS

WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects that can cause injury and damagel 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 responsible adults & 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

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.

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 in the #1 speed

position.

8. Use weights or a weighted load carrier in accordance with instructions with a grass catcher on slopes above 10 degrees (18% grade).

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.

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. 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.

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

IMPORTANT SAFETY INSTRUCTIONS

PREPARATION

(Continued From Previous Page)

5. 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.

6. Keep people and pets a safe distance from machine.

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.

10. Know how to STOP blade and engine quickly in preparation for emergencies.

1t. 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 worn spots.

OPERATION

1. Mount and dismount machine from left side.

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

Make sure blade is OFF and parking brake is set.

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 is ON 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.

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 joystick (if equipped) SLOWLY to maintain control during speed and directional changes.

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.

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 all cotter 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.

TIPS ON MOWING

FOR BEST RESULTS, USE THE FOLLOWING TIPS

WHEN MOWING:

When mowing, cut only 113 off of grass height. Cutting grass deeper could be harmful to your

lawn.

If cutting extremely tall grass, make one cutting

with the deck in its highest cutting position, then

lower the deck to desired position and make a second cut.

Mow when lawn is dry for best cutting. Mow often. Shorter grass clippings decompose

more quickly. Keep mower blades sharp. A dull blade tears and

shreds grass instead of cutting. Refer to "MOWER

BLADE SERVICE" in the Maintenance Section.

Alternate the mowing pattern every other time to reduce the possibility of grass matting.

CHUTE DEFLECTOR

(42" Cutting Deck)

FIGURE 13

A WARNING A I

Never attempt to operate mower without chute I deflector secured in the down position! I

Mow with engine speed control in FAST and ground speed control handle in a SLOW position.

Clean deck, removing all grass clippings and debris from the top and underside of deck after each use.

CHECKING BATTERY ELECTROLYTE

WARNING

The Electrolyte (Acid) produces a highly explosive gas. Keep all Sparks, Flame and Fire away from the

area when charging battery or when handling electrolyte or battery. Electrolyte (Acid) is a highly

corrosive liquid. Wear eye protection. In case of

eye or skin contact with Electrolyte (Acid), wash

all affective areas of the body immediately with water.

Clean top of battery, disconnect battery positive cable

to prevent arching, then carefully remove the battery

cell covers.

Visually check electrolyte level in each cell. Level should be 3116"above cell plates up to the fill rings.

Using distilled water, fill cells as needed to bring level up to, but not over, the fill rings. See Figure 29.

Replace cell covers and reconnect the positive cable if disconnected earlier.

FIGURE 29

BATTERY CHARGING PROCEDURE The engine is equipped with a flywheel altemator to charge battery. If the tractor is not run regularly,

connect battery to a charger monthly to maintain charge. If low, battery liquid could freeze at zero

degree temperatures causing cracking of the battery case. To prevent freezing, keep the charge up or remove the battery from the tractor and store battery in

warm, well ventilated area during the off season. Store

on wooden surface, not on cement floor.

Always remove the Negative (.) cable first to prevent arching and remove Positive (+) cable last.

To charge, connect a constant current charger (not trickle type) and follow instructions furnished

with the charger.

If time allows, slow charge at 1 amp for 10 hours, or as an alternate, fast charge at not more than 2.5 amps for four hours. Observe ALL Precautions

while charging.

Install Positive (+) cable first and install Negative(-) cable last. Apply a small amount of grease over the

terminals to prevent corrosion.

Re-install seat assembly over battery and secure in position with adjusting knobs. Leave knobs loose

until the seat is adjusted, then tighten.

ACTIVATING A NEW BATTERY Activating a new Battery with Electrolyte (Acid) will

bring it up to 80 % of full charge state. It must be brought up to full charge, which means 20% additional

charge is needed. Charge a new Battery for 2 hours on a slow charge rate of I Amp to bring it up to full charge

before installing it in tractor.
