If triggered by the Lift and/or Swing joystick
not being in the neutral position at Startup,
then (Lift and/or Swing joystick is returned
to its neutral position) and (Lift and Swing
permitted after controls initialized)
If triggered by the Lift and/or Swing joystick
is not in the neutral position when Foot-
