IMPORTANT SAFETY INSTRUCTIONS
WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects that
can cause injury and damage! Failure to comply with the following SAFETY instructions could result 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: (1-800-935-2967).
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.
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
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. DO NOT operate machine under any condition
where traction, steering or stability is doubtful.

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.
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.

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 amount of
grease over terminals to prevent corrosion.
10. Insert battery completely into battery housing.
11. Reinstall battery cover. See Figure4.16.
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
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.

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.
The engine must

heavily saturated with air-
borne 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 re-
sults In the following adverse
effects:
An Improperly serviced, dirt
clogged air cleaner will:
1. Increase fuel consumption
2. cause power loss
3. result in hard starting (
4. create smoke from unburned
fuel
5. produce carbon build-up ;
Internally
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:
6. foul spark plug electrodes
8. burn valves
9. wear out the engine pre-
maturely
10. COST YOU MONEY!

PRIMARY MAINTENANCE
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.
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

PRIMARY MAINTENANCE
On 4-cyle engines with an oll 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
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 ruined in less than 5
minutasl 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 use Snapper 2-cycle oil Pre-mix
the fuel and always shake the container
before filling the tank.
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.
