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 following 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.
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
(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) away
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. DO NOT operate machine under any condition
where traction, steering or stability is doubtful.
