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: [phone]).

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 operate blades in reverse. STO P 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.

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.

Section 2 - OPERATING INSTRUCTIONS

2.7. REVERSE LOCKOUT MECHANISM

Data indicates that tragic back-over accidents occur
each year. These accidents usually involve unsupervised
children. Many times these children have been given
rides on the mac hine and have been trained to view this
potentially dangerous piece of machinery as fun rather
than being taught how to avoid danger.

This riding mower has a Reverse Lockout Mechanism.
This mechanis m prevents the mower from being shifted
into reverse with the blades running. To shif t into reverse
you must first s top the blades and then s hif t to rever s e. It
is our recommendation that this mechanism remain
functional and the operator of this equipment develop the
habit of never backing up with the blades running. As the
Safety Instructions Indicate, DO NOT operate blades in

reverse. STOP BLADES, LOOK AND SEE BEHIND
AND DOWN for children, pets and hazards before
and while backing.

We realize that this could cause a change to your
previous mowing method but we encourage you to adjust
to this new system. Do not defeat the Reverse Lockout
Mechanism.

If you operate your mower near roadways or use
attachments that require quicker shifting to reverse,
there is an override lever provided. This lever can be
pushed and held before star ting the blades and will allow
reverse operation until the blade engagement lever is
moved to the “OFF” position, at which time the system
will return to its Reverse Lockout mode. This feature
should never be selected unless you are absolutely sure
that no children or others are present in the mowing area
and that all children are away and supervised by a
responsible adult.

2.7.1. Reverse Lockout Mechanism Override

1. Stop machine. Stop blades.

2. Depress and hold Override Lever.

3. Raise blade engagement lever to "ON".

4. Release override lever.

LOOK and SEE behind and down for children, pets
and hazards before and while backing.

IMPORTANT! DO NOT use the Reverse Lockout

Mechanism Override as the nor mal operating mode. To
return to the Reverse Lockout Mechanis m mode, move
the blade engagement lever down to the “OFF” position.
The Override will reset to Reverse Lockout.

2.7.2. Check the Reverse Lockout Mechanism
Before each use, check the Reverse Lockout
Mechanism for proper function. Perform the following
check with the engine “OFF”.

1. With engine “OFF”, raise blade engagement
lever to "ON".

2. The Reverse Lockout Mechanism must
prevent the speed control lever from going into
reverse.

DO NOT operate machine if Reverse Lockout
Mechanism is not functioning properly. Contact your
SNAPPER dealer immediately for assistance.

LOOK and SEE behind and down for children, pets

and hazards before and while backing.
BLADES must be turned off before backing machine.
DO NOT allow children on machine (even with

blades off) or in yard when mowing.

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.

4.5.3. BATTERY SERVICE

1. Remove battery. See Section on Battery Removal.

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

surface.

3. Using distilled water, refill cells as required to
cover cell plates of which can also be visualized
through the plastic battery case.

4. W ith 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.

6. If battery will not accept charge or is partially

charged after 10 hours of c harging at 1 amp, replace
with new battery.

4.5.4. BATTERY STORAGE

When out of season, it is recommended the battery
be removed, charged and stored.

1. Remove battery. (Refer to Section “BATTERY
REMOVAL”).

WARNING

DO NOT OVERFILL! DO NOT attempt to service or
charge the battery while it is installed on the machine.
DO NOT use “BOOST” chargers on the battery.

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 m ade 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
Battery Condition chart below shows the charge level
as measured by syringe float hydrometer, digital
voltmeter and five ball hydrometer.

4.5.6 NEW BATTERY PREPARA TION

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.

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

IMPORTANT: 3/16” above cell plates is the recommended
level. However do not try to meas ure this dimens ion. Never
place anything in battery other than specified electrolyte.

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 am ount of gr eas e over
terminals to prevent corrosion.

10. Insert battery completely into battery housing.

11. Reinstall seat assembly.

WARNING

Shield the positive terminal with terminal cover
located on battery harness. This preven ts 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.
