PROTECTION FOR CHILDRENPROTECTION AGAINST TIPOVERS

Tragic accidents can occur if the operator is not alert tothe presence of children. Children are often attracted tothe machine and the mowing activity. Children who havebeen given rides in the past may suddenly appear in themowing area for another ride and be run over or backed overby the machine. Never assume that children will remain
where you last saw them.
1. KEEP children out of the mowing area and under thewatchful care of a responsible adult other than theoperator.
2. DO NOT allow children in yard when machine isoperated (even with the blade OFF).
3. DO NOT allow children or others to ride on machine,
attachments or towed equipment (even with theblades OFF). They may fall and be seriously injured.
4. DO NOT allow pre-teenage children to operatemachine.
5. ALLOW only responsible adults & teenagers withmature judgment under close adult supervision tooperate machine.
6. DO NOT operate blades in reverse. STOP BLADES.
LOOK and SEE behind and down for children, petsand hazards before and while backing.
7. USE EXTRA CARE when approaching blind corners,
shrubs, trees, or other objects that may obscurevision.

(Continued From Previous Column)
5. STAY ALERT for holes and other hidden hazards. Tallgrass can hide obstacles. Keep away from ditches,
washouts, culverts, fences and protruding objects.
6. KEEP A SAFE DISTANCE (at least 3 feet) away fromedge 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 accordancewith 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 nothave 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 wheretraction, steering or stability is doubtful.
13. Always keep the machine in gear when going downslopes. DO NOT shift to neutral (or actuate hydro rollrelease) and coast downhill.

PREPARATIONPROTECTION AGAINST TIPOVERS

1.

Slopes are a major factor related to loss-of-control andtip-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 otherattachments; these affect the handling and the stability ofthe 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 faceof 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, turnblades OFF and back slowly straight down the slope.

3. Pull blade switch “OUT” to engage blade.
4. Release Override Lever

Data indicates that tragic back-over accidents occur
each
year.
These
accidents
usually
involveunsupervised children. Many times these children havebeen 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.

WARNINGLOOK and SEE behind and down for children, petsand hazards before and while backing.

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 remainfunctional 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.

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 andblades. Before proceeding, Read, Understand, andFollow all Safety Instructions and Warnings in thismanual 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.

We realize that this could cause a change to yourprevious mowing method but we encourage you toadjust 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 willallow 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 nochildren or others are present in the mowing area andthat all children are away and supervised by a
responsible adult.

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

DANGER
LOOK and SEE behind and down for children, petsand hazards before and while backing.
BLADES must be turned off before backing
machine.
DO NOT allow children on machine (even withblades off) or in yard when mowing.
