PROTECTION FOR CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted tothe
machine and the mowing activity. Childrenwho havebeen given ridesinthe past may suddenlyappear inthe mowing areafor another rideand be runover or backed overbythe
machine. Never assume that children will remainwhere you
lastsaw them.
1. KEEP children out of the mowing area and under the watchful care of a responsible adult other than the
operator.

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.
PROTECTION AGAINST TIPOVERS
Slopes are a major factor related to loss-of-control and tip- over accidents, which can result in severe injuryor death. All slopes require extra CAUTION. Ifyou cannot back up
the slope or ifyou feel uneasy on the slope, DO NOT mow
it. Use extra care with grass catchers or other attachments;
these affect the handling andthe stability of the machine.
1. DO NOT operate machine on slopes exceeding 15 degrees (27% grade).

Section 2 -OPERATING INSTRUCTIONS
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.
4. Move blade lever forward to "ON" position.
WARNING
LOOK and SEE behind and down for children, pets and hazards before and while backing.
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 will allow reverse operation until the blade pedals are released,
at which time the system wilt 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.

Section 3 - MAINTENANCE
WARNING
DO NOT attempt any adjustments, maintenance, service or repairs with the engine running. STOP engine. STOP blade. Engage parking brake. Remove
key. Remove spark plug wire from spark plug and secure away from plug. Engine and components are
HOT. Avoid serious burns, allow all parts to cool before working on machine. Fuel Filler Cap and vent
must be closed securely to prevent fuel spillage.

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. DO NOT
attempt to charge battery while installed on the machine. DO NOT use "BOOST" chargers on the battery.
4.6.3. BATTERY SERVICE

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.
WARNING
Shield the positive terminal with terminal cover
located on battery harness. This prevents metal from touching the positive terminal, which could cause
sparks.
4.6.6. 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.
