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).

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

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 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.
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.
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.
IaLn'_OdOhKazandsSbEeEfbreehWi=ARNI !NGk[no rg.Chi'd ren, P'_ets 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.
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.
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.
12
Section 3 - MAINTENANCE
WARNING
DO NOT attempt any adjustments, maintenance,
service or repairs with the engine running. STOP
engine. STOP blade. Engage parking brake. Remove
key. Remove spark plug wire from spark plug and
secure away from plug. Engine and components are
HOT. Avoid serious burns, allow all parts to cool
before working on machine. Fuel Filler Cap and vent
must be closed securely to prevent fuel spillage.

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

reasonable
ance
can protect it!
Snapper uses the best avail-
able engines and components
In their products In orcler to
provide long, satisfactory
service. However, proper
care is essential In
prolonging engine life. Dirt
Is your engine's enemy
number 11
The engine on your Snapper
product spends Its entire life
operating close to the ground at
high speed creating a virtual
storm of dust and dirt!
34
PRIMARY MAINTENANCE
The engine must
gulp about 12,000
gallons of air for
every gallon of fu(
used. Because of
its working environ-
ment, the air available .':
to your Snapper engine Is "
heavily saturated with air-
borne dirt particles.
(nowing that dirt will
quickly ruin an engine,
manufacturers equip their
engines with extremely
efficient air cleaners to
filter out 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 wilh
Damage caused by a poorly serviced air
cleaner is not covered under the engine
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
owner's manual for the type filter used. Pre-
vent dirt from falling Into the carburetor Intake
when servicing 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:
I
35
PRIMARY MAINTENANCE
Generally, wash foam-type filters
In a dishwashlng 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.
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.
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
lunder dry, dusty conditions
for a thorough cleaning of
fins.
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
i°o. 3. scuffed, scored
walls
4. overspeedlng
5. loss of power
6. complete failure of
engine.
Dirt can also be introduced
Into an engine In dirty fuel
from a contaminated
container. Always use clean
fresh fuel from aclean
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 pass-
ages. 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 oil to flow down the fill
tube to prevent a false full reading when the
level could actually be low and result In engine
damage.
36
PRIMARY MAINTENANCE
On 4-¢yle 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 overflowing at the
top of the fill hole.
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 mined in less than 5
minutes! 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 certified TC-W
oil such as Snapper's 2-cycle engine oil
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 filling the tank.
Change oil at regular Intervals using a ahigh
quality oil such as Snapper's small engine
formulated a-cycle engine o11. Refer to the
engine owner's manual for oil details.
