OPERATION
(Continued From Previous Column)
14. Exercise CAUTION when pulling loads. Limit loads
to those you can safely control and attach loads to
hitch plate as specified with SNAPPER attachment
instructions.
15. DO NOT operate engine in enclosed areas. Engine
exhaust gases contain carbon monoxide, a deadly
poison.
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.

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.
MAINTENANCE
1. DO NOT store machine or fuel container inside
where fumes may reach an open flame, spark or
pilot light such as in a water heater, furnace, clothes
dryer or other gas appliance. Allow engine to cool
before storing machine in an enclosure. Store fuel
container out of the reach of children in a well
ventilated, unoccupied building.
2. Keep engine free of grass, leaves or excess grease
to reduce fire hazard and engine overheating.
3. When draining fuel tank, drain fuel into an approved
container outdoors and away from open flame.
4. Check brakes frequently; adjust, repair or replace as
needed.
5. Keep all bolts, nuts and screws properly tight.
Check that all cotter pins are in proper position.
6. Always provide adequate ventilation when running

6. Blades must be OFF except when cutting grass.
Set blades in highest position when mowing
over rough ground.
7. Keep hands and feet away from rotating blades
underneath deck. DO NOT place foot on ground
while BLADES are ON or machine is in motion.
8. DO NOT operate machine without entire grass
catcher or guards in place. DO NOT point
discharge at people, passing cars, windows or
doors.
10. DO NOT change engine governor speed settings or
overspeed engine.
11. Lubricate machine at intervals specified in manual
to prevent controls from binding.
12. Mower blades are sharp and can cut. Wrap the
blades or wear heavy leather gloves and use
CAUTION when handling them.
13. DO NOT test for spark by grounding spark plug
next to spark plug hole; spark plug could ignite gas
exiting engine.
14. Have machine serviced by an authorized SNAPPER
dealer at least once a year and have the dealer
install any new safety devices.
15. Use only genuine SNAPPER replacement parts to
assure that original standards are maintained.
16. If battery is removed, DO NOT operate engine
without insulating Positive + battery cable terminal
with electrical tape, or sparking from battery cables
can result.
9. Slow down before turning.

WARNING
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

DO NOT use “BOOST” chargers on the battery.
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.

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.
