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. 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.
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. 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 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 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.
PREPARATION
1. 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.
2. Only mature, responsible persons shall operate the
machine and only after proper instruction.
3. 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.
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.

FIGURE 4.18
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
SCRAMBLER. DO NOT use "BOOST" chargers on the
battery. If battery is removed, DO NOT operate engine
without insulating Positive + battery cable terminal with
electrical tape, or sparking from the battery cables can
result.
4.6.4. BATTERY STORAGE

25
Section 4 - ADJUSTMENTS & REPAIR
4.6.5. 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
Battery Condition chart below shows the charge
level as measured by syringe float hydrometer,
digital voltmeter and five ball hydrometer.
4.6.6. 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.
WARNING
DO NOT OVERFILL! DO NOT attempt to charge l
battery while installed on the SCRAMBLER. DO NOT
use "BOOST" chargers on the battery.
IMPORTANT: DO NOT place anything in new battery
other than specified electrolyte.
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 to proper level.
7. Reinstall cell caps.
8. Install battery into power unit. Connect over flow
tube.
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.
WARNING
Shield the positive terminal with terminal cover
located on battery harness. This prevents metal from
touching the positive terminal, which could cause
sparks.

PRIMARY MAINTENANCE
®
vs.DIRT I
an
illustration of
how dirt can
ge your
engine & how
reasonable
maintenance
can protect it!
Snapper uses the best avail-
able engines and components
in their products in order 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 dirtl
31
PRIMARY MAINTENANCE
gulp about 12
gallons of air for
every gallon of
used. Because of
its working environ-
ment, the air avaUable
to your Snapper engine Is "
heavily saturated with air-
borne dirt particles.
__Knowing 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 parUcles 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 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
6. foul spark plug electrodes
7. score cylinder walls
8. burn valves
g. wear out the engine pre-
maturely
10. COST YOU MONEY!
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 afr 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:
32
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
l under 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
t ° 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 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 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 oil,
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.
33
PRIMARY MAINTENANCE
On 4-cyle engines with an oil level plug,
don't be fooled into thinking the engine has
sufficient lubricating oil 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.
I
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
mlnutesl 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 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 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 o11. Refer to the
engine owner's manual for oil details.
