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: [phone]).

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.

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.

4.5.5. 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 lead 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. The

chart on the next page shows the charge level as
measured by syringe float hydrometer, digital

voltmeter and five ball hydrometer.

4.5.6 NEW BATTERY PREPARATION

1. Remove battery from carton.

2. Place battery in a well ventilated area on a level non-

concrete surface.

3. Remove battery cell caps. Fill cells as required

with electrolyte (purchased separately) to proper level.
Fill to 3/16" above cell plates. Filling battery with

electrolyte will bring the battery to 80% charged state.

IMPORTANT: 3/16" above cell plates is the recommended
level. DO NOT place anything in battery other than specified

electrolyte.

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.

4. With cell caps removed, connect battery charger to

battery terminals; RED to positive (+) and BLACK to

negative (-) terminal.

5. Slow charge the battery at 1 amp for 2 hours to

bring the battery to full charge.

6. After charging, check level of electrolyte and add

as needed to bring level to 3/16" above cell plates.

7. Reinstall cell caps.

8. Slide battery partially into battery housing.

9. Connect positive (+) cable (red) first, from wiring
harness to the positive terminal (+) on battery using bolt

and nut provided in hardware bag. Connect negative (-)
cable (black) last, to negative terminal (-) on battery
using bolt and nut. Apply a small amount of grease over
terminals to prevent corrosion.

10. Insert battery completely into battery housing.

11. Reinstall seat assembly.

manufacturers equip their

engines with extremely
efficient air cleaners to

rout the harmful dirt.

As the dirt particles are stopped,

they build up and begin to clog
the outside of the filter. This

reduces the amount of air
available to the engine and causes

an over-rich fuel mixture which re-
suits In the following adverse

effects:

An Improperly serviced, dirt
clogged air cleaner will:

warranties. So, save yourself unnecessary
expenses and undue aggravation by keeping

the air cleaner properly serviced at the Intervals
specified In the engine owner's manual.

It doesn't take long to service an air cleaner.
Follow the specific Instructions In the engine

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 o11,

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

level could actually be low and result In engine

damage.

41

PRIMARY MAINTENANCE

On 4-cyle engines with an oil level plug,
don't be fooled Into thinking the engine has

sufficient lubricating oii if you can see "some"

oil in the opening - the level should always be
brought up to the point of at the
top of the fill hole.

Change oil at regular Intervals using s a high
quality oil such as Snapper's small engine

formulated 4-cycle engine o11. Refer to the
engine owner's manual for oll details.

On 2-cycle engines, lubrication must be

provided by an exact mixture of gasoline
and 2-cycle air-cooled engine oi1. A 2-cycle

engine that Is mistakenly run on straight
gasoline will be ruined in less than 5

minutesl If you keep straight gasoline In
addition to pre-mixed 2-cycle engine fuel,
be sure the containers are clearly marked

to avoid mix-up.

Snapper 2-cycle engines require a 32 to 1
mixture of gasoline and BIA eertlfled TC-W

oil such as Snapper's 2-cycle engine o11.
Many of the 2-cycle engine oils on the

market today make fantastic claims, but for
the best performance and long engine life,

always use Snapper 2-cycle o11.Pre-mix
the fuel and always shake the container
before filling the tank.

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.

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.

DO NOT use "BOOST" chargers on the battery. I

4.5.5. 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 lead 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. The

chart on the next page shows the charge level as
measured by syringe float hydrometer, digital

voltmeter and five ball hydrometer.

4.5.6 NEW BATTERY PREPARATION

1. Remove battery from carton.

2. Place battery in a well ventilated area on a level non-

concrete surface.

3. Remove battery cell caps. Fill cells as required

with electrolyte (purchased separately) to proper level.
Fill to 3/16" above cell plates. Filling battery with

electrolyte will bring the battery to 80% charged state.

IMPORTANT: 3/16" above cell plates is the recommended
level. DO NOT place anything in battery other than specified

electrolyte.

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.

4. With cell caps removed, connect battery charger to

battery terminals; RED to positive (+) and BLACK to

negative (-) terminal.

5. Slow charge the battery at 1 amp for 2 hours to

bring the battery to full charge.

6. After charging, check level of electrolyte and add

as needed to bring level to 3/16" above cell plates.

7. Reinstall cell caps.

8. Slide battery partially into battery housing.

9. Connect positive (+) cable (red) first, from wiring
harness to the positive terminal (+) on battery using bolt

and nut provided in hardware bag. Connect negative (-)
cable (black) last, to negative terminal (-) on battery
using bolt and nut. Apply a small amount of grease over
terminals to prevent corrosion.

10. Insert battery completely into battery housing.

11. Reinstall seat assembly.

manufacturers equip their

engines with extremely
efficient air cleaners to

rout the harmful dirt.

As the dirt particles are stopped,

they build up and begin to clog
the outside of the filter. This

reduces the amount of air
available to the engine and causes

an over-rich fuel mixture which re-
suits In the following adverse

effects:

An Improperly serviced, dirt
clogged air cleaner will:

warranties. So, save yourself unnecessary
expenses and undue aggravation by keeping

the air cleaner properly serviced at the Intervals
specified In the engine owner's manual.

It doesn't take long to service an air cleaner.
Follow the specific Instructions In the engine

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 o11,

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

level could actually be low and result In engine

damage.

41

PRIMARY MAINTENANCE

On 4-cyle engines with an oil level plug,
don't be fooled Into thinking the engine has

sufficient lubricating oii if you can see "some"

oil in the opening - the level should always be
brought up to the point of at the
top of the fill hole.

Change oil at regular Intervals using s a high
quality oil such as Snapper's small engine

formulated 4-cycle engine o11. Refer to the
engine owner's manual for oll details.

On 2-cycle engines, lubrication must be

provided by an exact mixture of gasoline
and 2-cycle air-cooled engine oi1. A 2-cycle

engine that Is mistakenly run on straight
gasoline will be ruined in less than 5

minutesl If you keep straight gasoline In
addition to pre-mixed 2-cycle engine fuel,
be sure the containers are clearly marked

to avoid mix-up.

Snapper 2-cycle engines require a 32 to 1
mixture of gasoline and BIA eertlfled TC-W

oil such as Snapper's 2-cycle engine o11.
Many of the 2-cycle engine oils on the

market today make fantastic claims, but for
the best performance and long engine life,

always use Snapper 2-cycle o11.Pre-mix
the fuel and always shake the container
before filling the tank.
