Entrance Door Emergency Release
Depending upon purchase options, the entrance door may be manually-operated,
electrically operated, or air operated.
Manually operated doors employ a door control rod connected to a handle
mounted on the dash panel near the Driver. An over-center cam latching mechanism
is released by the driver’s thumb or palm when the handle is opened, and snaps back
into latched position when closed.
Electric or air-operated doors are equipped with emergency release levers so that
passengers can open the door even if the power is off or disabled.
The optional electrically-controlled entrance door is driven by a motor and gear
mechanism in the door header panel. A lever protruding from the header panel serves
to disengage the drive gear mechanism so that the door can be manually pushed
open or shut. This serves a dual purpose: To allow the driver to close the door after
parking and leaving the vehicle, and to serve as a quick door release in the case of
emergency.
To release the door, push the lever to the left. The door can then be pushed open
or closed manually. To re-engage the door drive mechanism, push the lever to the
right.
Air-operated doors use system air pressure to open the door. Air-operated doors
are also equipped with an emergency release lever mounted above the door. In the
case of air pressure failure, the door closure can be released by flipping the lever to-
ward the Open direction indicated.
Push forward to release the door mechanism so that the door can
be manually opened or closed. Push rearward to engage the door
mechanism for normal control of the door by the switch panel.
