FAILURE TO FOLLOW SAFE OPERATING PRACTICES
MAY RESULT IN SERIOUS INJURY.
* 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.
* Read this manual completely as well as other manuals that came
with your mower.
* Keep others off the tractor (only one person at a time)
* 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 OSHAAPPROVED
OPERATION.
* DO NOT mow on wet grass. Wet grass reduces traction and steering
control.
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.
