z z Procedure D
If the red EMS WARNING light (1) is on, try to
reset it by pressing it in then releasing it several
times. If the red light goes out, try to restart the
motor and lower the platform in the normal way.
If the red light stays on and the green EMS
STATUS light (2) is on, the main boom can be
retracted in the normal way (if it is extended) or
lowered in the normal way (if it is almost
completely retracted). Use one or the other of
those two functions to retrieve the platform as
long as the green EMS STATUS light is on.
NOTE: If the green light goes out, try to reset
the red EMS WARNING light again to see if
the green light will come back on.
If the red light stays on and the green light stays
off, continue with this procedure.
