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.
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.
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.
PROTECTION AGAINST TIPOVERS

2.6 REVERSE LOCKOUT MECHANISM
Data indicates that tragic back-over accidents occur each year. These accidents usually involve
unsupervised children. Many times these children have been given rides on the machine and have been trained to view this potentially dangerous piece of machinery as
fun rather than being taught how to avoid danger.
This riding mower has a Reverse Lockout Mechanism. This mechanism prevents the mower from being shifted
into reverse with the blade running. To shift into reverse you must first stop the blade by releasing the blade pedals and then shift to reverse. It is our
recommendation that this mechanism remain functional and the operator of this equipment develop the habit of
never backing up with the blade running. As the Safety
Instructions Indicate, DO NOT operate blades in
reverse. STOP BLADES, LOOK AND SEE BEHIND AND DOWN for children, pets and hazards before
and while backing.
We realize that this could cause a change to your previous mowing method but we encourage you to
adjust to this new system. Do not defeat the Reverse
Lockout Mechanism.
2.6.1.
Reverse Lockout Mechanism Override
1.
Stop machine. Stop blade.
2.
Depress and hold Override Lever.
3.
Depress and hold Blade Pedals. Release Override Lever.
.
Move blade lever forward to "ON" position.
WARNING A I
LOOK and SEE behind and down for children, pets I and hazards before and while backing. I
IMPORTANT: DO NOT use the Reverse Lockout Mechanism Override as the normal operating mode. To
return to the Reverse Lockout Mechanism mode, release blade pedals to turn blade off. The Override will
reset to Reverse Lockout. Check the Reverse Lockout Mechanism frequently for proper function. With the
blade pedals depressed, the shift lever must not go into reverse. DO NOT operate machine if Reverse Lockout
Mechanism is not functioning properly. Contact your local Snapper dealer for assistance.
If you operate your mower near roadways or use attachments that require quicker shifting to reverse,
there is an override lever provided. This lever can be pushed and held before starting the blade and wilt allow
reverse operation until the blade pedals are released, at which time the system will return to its Reverse Lockout
mode. This feature should never be selected unless you are absolutely sure that no children or others are
present in the mowing area and that all children are away and supervised by a responsible adult.
DANGER
LOOK and SEE behind and down for children, pets
and hazards before and while backing.
BLADES must be turned off before backing
machine.
DO NOT allow children on machine (even with
blades off) or in yard when mowing.

3. Bring battery to full charge, if required.
4. Store battery in an area away from the RIDER on a
wood surface. DO NOT STORE BATTERY ON A
CONCRETE SURFACE.
4.6.5. 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. 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.
lj , WARNING
DO NOT attempt to charge battery while installed on the I Riding Mower. DO NOT use "BOOST" chargers on the
battery. DO NOT OVERFILL! I
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. Remove the hair pin and swivel from the deck
support to allow clearance for battery installation.
9. Slide battery partially into battery housing.
10. 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.
11. Insert battery completely into battery housing.
12. Reinstall battery cover. See Figure4.17.
13. Reinstall swivel and hair pin for deck support.
4.6.6. 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 chart on the next page shows the charge level as measured by syringe float hydrometer, digital
voltmeter and five ball hydrometer.
Shield the positive terminal with terminal cover I
located on battery harness. This prevents metal from
touching the positive terminal which could cause l sparks. I
(Battery Testing Chart on Next Page)
IMPORTANT: 3/16" above cell plates is the recommended
level. DO NOT place anything in battery other than specified
electrolyte.
