TRAVEL

AVOID DEATH OR SERIOUS INJURY
1. Before operating the travel levers, make sure that you
know in which direction the machine is pointing. Look
at the end of the track assemblies. If the drive motors
are visible while sitting in the operator's seat, you are
looking at the back end of the track assembly
(therefore, you are looking backwards). In this case,
the response of the travel levers will be the reverse of
normal operation.
2. Before moving, make sure that there are no personnel
in the way or on the machine. Sound the horn to alert
workers that you are about to move the machine.
3. Be sure the path is clear during travel.
4. Use extreme caution when reversing travel. Be sure
there is a clear path behind the machine.
5. Make sure to operate the travel control levers
smoothly to avoid sudden starts or stops.
6. Before leaving the operator's seat, make sure to lock
out all control systems and stopped engine to avoid
accidental activation.
