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 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 b lades in reverse. STO P BLADES. LOOK and SEE behind an d 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 EXT REME 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

WARNING

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 mac hine 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 mechanis m prevents the mower from being shifted into reverse with the blades running. To shif t into reverse you must first s top the blades and then s hif t to rever s e. 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 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 m ode. 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 nor mal 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.
