PROTECTION FOR CHILDREN

PROTECTION AGAINST TIPOVERS

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 blades OFF).
3. DO NOT allow children or others to ride on
machine or on attachments (even with the blade
OFF). They may fall and be seriously injured.
4. DO NOT allow pre-teenage children to operate
machine.
5. ALLOW only adults or responsible 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.

(Continued From Previous Column)
4. AVOID uphill starts. If machine stops going uphill
or tires lose traction, turn blades OFF and back
slowly down the slope.
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.
12. Operator Protective Structures are available for
this machine through your local Snapper dealer.

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.

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 mowerrelated 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.

IMPORTANT SAFETY INSTRUCTIONS

OPERATION

(Continued From Previous Page)
5. Practice operation of machine with BLADES OFF
to learn controls and develop skills.
6. Check the area to be mowed and remove all
objects such as toys, wire, rocks, limbs and other
objects that could cause injury if thrown by blades
or interfere with mowing.
7. Keep people and pets out of mowing area.
Immediately, STOP blades, STOP engine, and
STOP machine if anyone enters the area.
8. Check shields, deflectors, switches, blade controls
and other safety devices frequently for proper
operation and location.
9. Make sure all safety decals are clearly legible.

10. Protect yourself when mowing and wear safety
glasses, long pants and substantial footwear.
11. Know how to STOP blades and engine quickly in
preparation for emergencies.
12. Use extra care when loading or unloading the
machine into a trailer or truck.
13. Check grass catcher components frequently for
signs of wear or deterioration and replace as
needed to prevent injury from thrown objects
going through weak or worn spots.

(Continued From Previous Column)
12. Mow only in daylight or with good artificial light.
13. Move motion control levers SLOWLY to maintain
control during speed and directional changes.
14. Exercise CAUTION when pulling loads. DO NOT
pull loads greater than 300 pounds. Avoid jack
knifing. DO NOT turn sharply.

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.

WARNING
Cables must be connected to battery terminals in the
proper position. RED (Positive) cable must go to the
( + ) terminal. BLACK (Negative) cable must go to the
( - ) terminal.

4.7.3. BATTERY SERVICE

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.

WARNING
Shield the positive terminal with terminal cover
located on battery harness. This prevents metal from
touching the positive terminal, which could over
heat battery and/or battery cable and cause sparks.
DO NOT attempt to charge battery while installed on
the Zero Turning Radius Mower. DO NOT use
“BOOST” chargers on the battery.

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

4.7.4. 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
before testing. The chart on the next page
shows the charge level as measured by
syringe float hydrometer, digital voltmeter
and five ball hydrometer.

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. Install battery into power unit.
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.

cover any machine or component that has been altered or modified, changing safety, performance, or durability.

DISCLAIMER OF WARRANTY
Implied warranties, including those of merchantability and fitness for a particular purpose, are limited to
two (2) years from purchase date for the original purchaser's use, and up to the extent permitted by law
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 warranty lasts, or do not allow the
exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may
not apply to you.
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
