IMPORTANT SAFETY INSTRUCTIONS

WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects that
can cause injury and damage! Failure to comply with the follow ing SAFETY instructions could result in serious
injury or death to the operator or other persons. The owner of the machine must understand these instructions
and must allow only persons who understand these instructions to operate machine. Each person operating
the machine must be of sound mind and body and must not be under the influence of any substance, which
might impair vision, dexterity or judgment. If you have any questions pertaining to your machine which your
dealer cannot answer to your satisfaction, call or write the Customer Service Department at SNAPPER,
McDonough, Georgia 30253. Phone: [phone]).

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. Children who have
been given rides in the past may suddenly appear in the
mowing area for another ride and be run over or backed over
by the machine. 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 other than the
operator.

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,
attachments or towed equipment (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 starting, stopping or turning on slopes. If
machine stops going uphill or tires lose traction, turn
blades OFF and back slowly straight down the slope.

PROTECTION AGAINST TIPOVERS

(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) aw ay 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. Chose a low enough speed setting so that you will not
have to stop or shift on a slope. Tires may lose traction
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.

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 mower-related
injuries. These operators should evaluate their ability
to operate the mower safely enough to protect
themselves and others from serious injury.

4. Handle fuel w ith 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.

Section 2 - OPERATING INSTRUCTIONS

2.7. 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 blades running. To shift into reverse
you must first stop the blades 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 blades running. As
the Safety Instructions Indicate, DO NOT operate

blades with machine 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.

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 engaging the blades and will
allow reverse operation until the blade switch is pushed
in to the “OFF” position, 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.

2.7.1. Reverse Lockout Mechanism Override

1. Stop machine. Stop blades.

2. Depress and hold Override Lever.

3. Pull blade switch “OUT” to engage blade.

4. Release Override Lever

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,
disengage (STOP) blades by pushing blade switch in to
the “OFF” position. The Override will reset to Reverse
Lockout.

2.7.2. Check the Reverse Lockout Mechanism
Before each use, check the Reverse Lockout
Mechanism for proper function. The following
procedure requires the operation of the engine and
blades. Before proceeding, Read, Understand, and
Follow all Safety Instructions and Warnings in this
manual and on the machine.

1. Complete Pre-Start Checklist.

2. Move machine to clear open area. DO NOT

allow children or others in area.

3. Start engine.

4. Pull blade switch “OUT” to engage blades.

5. Reverse Lockout Mechanism must prevent

speed control lever from going into reverse.

DO NOT operate machine if Reverse Lockout
Mechanism is not functioning properly. Contact your
SNAPPER dealer immediately for assistance.

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.
