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 blad es 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.

3. Data indicates that operators age 60 and 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 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
2.6 REVERSE LOCKOUT MECHANISM
Data indicates that tragic back-over accidents occur
each year. These accidents usually involve
unsupervised children. Many times these childr en have
been given rides on the mac hine and have been trained
to view this potentially dangerous piece of m achinery as
fun rather than being taught how to avoid danger.
This riding mower has a Rever se Lockout Mechanism.
This mechanis m prevents the mower fr om being shifted
into reverse with the blade running. To shift into reverse
you must first stop the blade and then shift to rever se. It
is our recommendation that this mechanism remain
functional and the operator of this equipment develop
the habit of never backing up with the blade 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 starting the blade and will allow
reverse operation until the blade pedals are released, at
which time the system will return to its Rever se Lock out
mode. This featur e s hould never be s elec ted unles s 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.
2.6.1. Reverse Lockout Mechanism Override
1. Stop machine. Stop blade.
2. Depress and hold Override Lever.
3. Depress and hold Blade Pedals. Release
Override Lever.
4. Move blade lever forward to “ON” position.
LOOK and SEE b ehind and down fo r children, pets
and hazards before and while backing.
IMPORTANT: DO NOT use the Reverse Lockout
Mechanism Override as the nor mal operating mode. T o
return to the Reverse Lockout Mechanism mode,
release blade pedals to turn blade off. The Overr ide will
reset to Reverse Lock out. Check the Reverse Lockout
Mechanism frequently for proper function. With the
blade pedals depressed, the shift lever mus t not go into
reverse. DO NOT operate m achine if Reverse Lockout
Mechanism is not functioning properly. Contact your
local Snapper dealer for assistance.

4.6.5. BATTERY TESTING
There are two types of battery tests: Unloaded and
Loaded. The unloaded test is the proc edur e that will
be discussed. It’s the sim plest and most comm only
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.
