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 follow ing 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
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.
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 w ith 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.

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.

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.
Shield the positive terminal with terminal cover
located on battery harness. This prevents metal
from touching the positive terminal, which could
cause sparks.
4.4.6. 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
Battery Condition chart below shows the charge
level as measured by syringe float hydrometer,
digital voltmeter and five ball hydrometer.

abuse, improper lubrication, normal wear, or other cause beyond the control of SNAPPER. This warranty does not
cover any machine or component part that has been altered or modified changing safety, performance, or durability.

days from purchase for the original purchaser's commercial, rental or other non-residential use, and to the
extent permitted by law, any and all implied warranties are excluded. This is the exclusive remedy. Liabilities
for consequential damages, under any and all warranties are excluded.
Some states do not allow limitations on how long an implied w arranty lasts, or do not allow the exclusion or
