Phone: (1-800-935-2967).
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.

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.
