disengage the safety latches, and then by
pushing out the window frame (Fig. 32).
Emergency operating instruction decals are

designed to answer the twenty pound resistance
criteria for opening the emergency window. If
this handle should be replaced:
1. Remove the screws and bolts securing it to
the emergency exit window;
2. Install a new release bar, reverse the
procedure.
NOTE
Check the legal twenty pound maximum
resistance to be sure to comply with
regulations.

8.2.2 Emergency Exit Window Adjustment
Emergency exit windows should be checked
periodically for easy opening and closing.
Pulling the lower part of the release bar with
both hands placed near the safety latches
should disengage both locks on the window
simultaneously. The tension required to release
the window should not exceed twenty pounds (9
kg) of force.
The release bar mechanism itself has been
designed such as no adjustments are
necessary.
If too much effort is required to disengage the
locks when pulling the release bar or if the
window doesn’t close tightly or rattles, check for
interference by foreign objects or nearby parts
into mechanism, such as the microswitch,
rubber seal, wires, etc. Correct situation
immediately.
NOTE
Tangs on the lock must be in a horizontal
position.
8.2.3 Emergency Exit Window Replacement

2. Remove the stop blocks from the top
exterior of the window.
3. Push the glass window out ninety degrees
(90°).
WARNING
The window may fall out.
4. The window is free and can be unhooked.
Reverse the procedure to install a new
emergency exit window.
8.3 ROOF ESCAPE HATCH
The vehicle can be equipped with one or two
escape hatches. The escape hatch is designed
to provide years of reliable service with a
minimum of maintenance. All components are
rust proof, and moving parts are Teflon coated
to eliminate need for lubrication. Should water
infiltrate the vehicle from the escape hatch, refer
to the heading "Sealing" in this paragraph for
procedures on how to seal this area.
