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 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.

(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.

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.
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 blade
or interfere with mowing.

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.

blade. STOP engine. Set brake. Remove key. Remove
spark plug wire from spark plug and secure wire
away from spark plug. Engine and components can
be extremely hot. Avoid burns by allowing engine
and components sufficient time to cool. Never
attempt to service or charge the battery while it is
installed on the YARD CRUISER. Shield the positive
terminal with terminal cover located on battery harness.
This prevents metal from touching the positive
terminal, which could cause sparks. Cables must be
connected to battery terminals in the proper position as
shown. 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.

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 YARD CRUISER. DO NOT use
“BOOST” chargers on the battery.
4.4.3. BATTERY SERVICE

WARNING

WARNING

Shield the positive terminal with terminal cover
located on battery harness. This prevents metal
from touching the positive terminal, which could
cause sparks.
4.4.6. 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.

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

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.

WARNING
DO NOT OVERFILL! DO NOT attempt to charge
battery while installed on the Yard Cruiser. DO NOT
use “BOOST” chargers on the battery.
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. 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.

3 YEAR LIMITED WARRANTY
For three (3) years from purchase date for the original purchaser's residential, non-commercial use, SNAPPER, through
any authorized SNAPPER dealer will replace, free of charge (except for taxes where applicable), any part or parts found
upon examination by the factory at McDonough, Georgia, to be defective in material or workmanship or both.
For ninety (90) days from purchase date for the original purchaser's commercial, rental, or other non-residential use,
SNAPPER, through any authorized SNAPPER dealer will replace, free of charge, any part or parts found upon
examination by the factory at McDonough, Georgia, to be defective in material or workmanship or both.
All transportation costs incurred by the purchaser in submitting material to an authorized SNAPPER dealer for
replacement under this warranty must be paid by the purchaser.
This warranty does not apply to engines and their components, and batteries, as these items are warranted separately.
This warranty does not apply to parts that have been damaged by accident, alteration, 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.
Batteries have a one (1) year prorated warranty period with free replacement if required during the first ninety (90) days
from the original purchase date. SNAPPER will not be responsible for any installation cost incurred. The battery warranty
only covers original equipment batteries and does not cover damage to the battery or machine caused by neglect or

There is no other express warranty.
DISCLAIMER OF WARRANTY
Implied warranties, including those of merchantability and fitness for a particular purpose, are limited to three
(3) years from purchase date for the original purchaser's residential or other non-commercial use, and ninety
(90) 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 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.
