On some machines it may be necessary to pause about
three seconds in the on position before going to start so
the starter can engage.

long time, turn the switch to off to shut off the engine
and save fuel

upper controls are not in use to protect against un-
intentional operation.

forward and reverse motion of the aerial platform. It is
also used to steer the machine. The steering and drive
