PROTECTION

FOR CHILDREN

PROTECTION

AGAINST TIPOVERS

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. Children who have been
given rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over by the
machine. 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 other than the
operator.
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,
attachments or towed equipment (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.

(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. Chose a low enough speed setting so that you will not
have to stop or shift on a slope. Tires may lose traction
on slopes even though the brakes are functioning
properly.
12. DO NOT operate machine under any condition where
traction, steering or stability is doubtful.
13. Always keep the machine in gear when going down
slopes. DO NOT shift to neutral (or actuate hydro roll
release) and coast downhill.

PROTECTION

PREPARATION

AGAINST TIPOVERS

Slopes are a major factor related to loss-of-control and tipover 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 starting, stopping or turning on slopes. If
machine stops going uphill or tires lose traction, turn
blades OFF and back slowly straight down the slope.

2.
3.

Read, understand, and follow instructions and
warnings in this manual and on the machine, engine
and attachments. Know the controls and the proper
use of the machine before starting.
Only mature, responsible persons shall operate the
machine and only after proper instruction.
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.
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.
Practice operation of machine with BLADES OFF to
learn controls and develop skills.

Engine Power Rating Information
The gross power rating labels for individual gas engine models meet or exceed SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating Procedure)
and rating performance
has been
obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Actual gross engine power may be
lower and is affected by, but not limited to, ambient operating conditions and engine to engine variability. Given
both the wide array of products on which engines are placed, and the variety of environmental
issues applicable
to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of
power equipment (actual "on-site" or net horsepower). This difference is due to a variety of factors including, but
not limited to, accessories
(air cleaner, exhaust, charging,
cooling, carburetor,
fuel pump, etc.), application
limitations, ambient operating conditions (temperature, humidity, altitude), and engine to engine variability.

Statement of Usage
This manual contains safety information to make you aware of the hazards and
risks associated with the machine and how to avoid them. This machine is
designed and intended to be used and maintained according to the manual for
finish cutting of established lawns and is not intended for any other purpose. It
is important that you read and understand these instructions thoroughly before
attempting to start or operate this equipment.

REVERSE LOCKOUT MECHANISM

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.
.
Move blade lever forward to "ON" position.

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 machine 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 mechanism prevents the mower from being shifted
into reverse with the blade running. To shift into reverse
you must first stop the blade by releasing the blade
pedals
and then shift to reverse.
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.

WARNING

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 normal operating mode. To
return to the Reverse Lockout Mechanism mode,
release blade pedals to turn blade off. The Override will
reset to Reverse Lockout. Check the Reverse Lockout
Mechanism frequently for proper function. With the
blade pedals depressed, the shift lever must not go into
reverse. DO NOT operate machine if Reverse Lockout
Mechanism is not functioning properly. Contact your
local Snapper dealer for assistance.

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 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.

Am putation

hazard

,Do not mow when children or others are
around.

DANGER
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.

•Do not carry riders (especially children)

-Look down and behind before and while
backing.

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. DO NOT
attempt to charge battery while installed on the RIDER.
DO NOT use "BOOST" chargers on the battery.

DO NOT attempt to charge battery while installed on
the Riding Mower. DO NOT use "BOOST" chargers on
the battery. DO NOT OVERFILL!
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 celt caps.
8. Remove the hair pin and swivel from the deck
support to allow clearance for battery installation.
9. Slide battery partially into battery housing.
10. Connect positive (+) cable (red) first, from wiring
harness to the positive terminal (+) on battery using

4.6.3. BATTERY SERVICE
1. Remove battery. Refer to Section "BATTERY
REMOVAL".
2. Place battery in a welt 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. 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.
6. If battery will not accept charge or is partially
charged after 10 hours of charging at 1 amp,
replace with new battery.

4.6.6. 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.

4.6.4. BATTERY STORAGE
If mower is to be stored out of season on its rear
bumper,
it is recommended
the battery be
removed, charged and stored.
1. Remove battery. Refer to Section "BATTERY
REMOVAL".
2. Perform battery service.
3. Bring battery to full charge, if required.
4. Store battery in an area away from the RIDER on
a wood surface. DO NOT STORE BATTERY ON A
CONCRETE SURFACE.
4.6.5. 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. Filling battery with electrolyte will bring the
battery to 80% charged state.
4. With cell caps removed, connect battery charger
to battery terminals; RED to positive (+) and BLACK
to negative (-) terminal.

I Shield the positive
terminal
with terminal
cover
located on battery harness. This prevents metal from
touching the positive terminal, which could cause
sparks.
