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.

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.

PREPARATION

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.

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.

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.

Move blade lever forward to "ON" position.

WARNING

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 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.

A I

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

Section 3- MAINTENANCE
5. After all the oil has drained, close the drain and

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. 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
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.
11. Insert battery completely into battery housing.
12. Reinstall battery cover. See Figure4.15.
13. Reinstall swivel and hair pin for deck support.

4.6.3. BATTERY SERVICE
1. Remove battery. Refer to Section "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. 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. Fill to 3/16" above cell plates. 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.

Shield the positive terminal with terminal cover I
located on battery harness. This prevents metal from
touching the positive terminal which could cause l
sparks.
I
(Battery Testing Chart on Next Page)

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

PRIMARY MAINTENANCE

g that dirt will
quickly ruin an engine,
manufacturers equip their
engines with extremely
efficient air cleaners to
filter out the harmful dirt.
°;.

"; .. o
The engine must
gulp about 12,000
gallons of air for

used. Because of
its working environment, the air available
to your Snapper engine Is "
heavily saturated with airborne dirt particles.

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 results In the following adverse
effects:

Damage caused by a poorly serviced air
cleaner Is not covered under the engine
warranUes. 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.

An Improperly serviced, dirt
clogged air cleaner will:

1.

5. produce carbon build-up ;

6. foul spark plug electrodes
7. score cylinder walls
8. burn valves
9. wear out the engine prematurely
10. COST YOU MONEY!

It doesn't like long to ssrvlce an air cleaner.
Follow the specific instructions In the engine
owner's manual for the type filter used. Prevent dirt from falling Into the carburetor Intake
when ssrvicing your air cleaner. Make sure
components are Installed In correct sequence
after servicing to prevent unfiltered air from
entering the engine. Some servicing hints on
several common types are:

PRIMARY MAINTENANCE
Air Is also needed to keep
your engine cool. Dirt, dust
& debris build up to restrict
and clog cooling air Intake
screens and fins. Clean
screens and fins at frequent
Intervals. The engine blower
housing and shrouds should
be removed at least once
each season or more often
t under dry, dusty conditions
for a thorough cleaning of
fins.
Generally, wash foam-type filters
In a dlshwashlng detergent and
water solution. Rinse and wring
dry, then saturate with oil and
squeeze out excess. Failure to
re-oil this type filter will ruin the
engine.

Failure to keep external
surfaces clean not only
presents fire hazards, but
causes overheating and
resulting engine damages
such as:
1. distorted valve guides
2. sticking valves
t _°o. 3. scuffed, scored
,.,.
walls
4. overspeedlng
5. loss of power
6. complete failure of
engine.

Clean paper elements by tapping
lightly. Blowing with air will
rupture paper elements.
Use a flashlight to detect clogged
or torn paper elements - replace If
damaged In any way.

Dirt can also be introduced
into an engine In dirty fuel
from a contaminated
container. Always use clean
fresh fuel from a clean
container to guard against
dirt, sludge and water
contamination.

Be aware that fuel breaks
down in storage and forms
gummy compounds which
will block carburetor passages. Never use fuel more
than 3 months old. Drain
tank then run the engine out
of fuel before storing during
the off-season.

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.

PRIMARY MAINTENANCE
On 2-cycle engines, lubrication must be
provided by an exact mixture of gasoline
and 2-cycle air-cooled engine oil 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
addlUon 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 certified 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 usa Snapper 2-cycle oil Pre-mix
the fuel and always shake the container
before tilting the tank.

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
at the
top of the fill hole.

Change oil at regular Intervals using a a high
quality oil such as Snapper's small engine
formulated 4-cycle engine oil Refer to the
engine owner's manual for oil details.
