IMPORTANT SAFETY INSTRUCTIONS
WARNING: This powerf ul cutting machine is capab le of amputating hand s and feet and can throw objects that
can cause injury and damage! Failure to comply with the follow ing SAFETY instru ctions could resu lt 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: (1-800-935-2967).
PROTECTION FOR CHILDREN
Tragic accidents can occu r 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 ch ildren or ot her p asseng ers to rid e
on machine or on attachments (even with the
blade OFF). They may fall and be seriously injured.
4. DO NOT allow pre-teenage children to operate
machine.
5. ALLOW only adults or responsible teenagers with
mature judgment under close adult supervision to
operate machine.
6. BE SURE the area is clear of others before
mowing and turn machine OFF if anyone enters
the area.
7. DO NOT mow in reverse unless absolutely
necessary. LOOK BEHIND and down for small
children before and when backing.
8. 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
it, DO NOT mow it. Use ext ra care with grass catchers
or other attachments; these can change the stability
of the machine.
1. DO NOT operate machine on slopes exceeding 15
degrees (27% grade).
2. Exercise EXTREME CAUTION on slop es above 10
degrees (18% grade). Turn blade OFF when
traveling uphill. Use first speed and avoid sudden
or sharp turns.
3. DO NOT mow back and forth across face of
slopes. Mow up and down.
PROTECTION AGAINST TIPOVERS
(Continued From Previous Column)
4. AVOID uphill starts. If machine stops going uphill
or tires lose traction, turn blade OFF and back
slowly down the slope.
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
mower 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 su pplied 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 mow on wet grass. Reduced traction
could cause sliding.
11. DO NOT mow under any condition where traction,
steering or stability is doubtful without first test
driving over the terrain with blade OFF.
12. Operator Protective Structures are available for
this machine through your local Snapper dealer.
PREPARATION
1. Read this manual, get to know where all controls
are located and practice how to use them before
starting for the first time, and at the beginning of
each season. Read and follow Warnings and
Instructions on engine and machine. Read and
follow operator’s manual and instructions
furnished with attachments.
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.
