WARNING
FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT IN
SERIOUS INJURY OR DEATH.
Read this manual completely as well as other manuals that came with your mower.•
DO NOT operate on steep slopes. To check a slope, attempt to back up it (with the•
cutter deck down). If the machine can back up the slope without the wheels slipping,
reduce speed and use extreme caution.
Under no circumstances should the machine be operated on slopes greater than 15•
degrees. ALWAYS FOLLOW OSHA APPROVED OPERATION.
Stay two cut widths away from slopes, drop offs, ditches and retaining walls.•
DO NOT mow on wet grass. Wet grass reduces traction and steering control.•
Keep all shields in place, especially the grass discharge chute.•
Before performing any maintenance or service, stop the machine and remove the•
spark plug wire and ignition key.
If a mechanism becomes clogged, stop the engine before cleaning.•
Keep hands, feet and clothing away from power-driven parts.•
Keep others off the mow• er (only one person at a time)
REMEMBER - YOUR MOWER IS ONLY AS SAFE AS THE OPERATOR!
HAZARD CONTROL AND ACCIDENT PREVENTION ARE DEPENDENT UPON THE AWARENESS,
CONCERN, PRUDENCE, AND PROPER TRAINING OF THE PERSONNEL INVOLVED IN THE
OPERATION, TRANSPORT, MAINTENANCE, AND STORAGE OF THE EQUIPMENT.
