WARNING
Releasing the spring brakes on an un-
secured
vehicle could lead to an acci-
dent. The vehicle could roll, which may
result in death, personal injury, equip-
ment or property damage. Always se-
cure the vehicle with wheel chocks,
chains, or other safe means to prevent
rolling before manually releasing the
spring brakes.
To move a vehicle immobilized by the
spring brakes due to loss of air pressure in
the brake system, perform the following
procedure:
1.
Remove the cap from the spring
chamber
2. Remove the release stud assembly
from the side pocket, and remove
the release nut and washer from
the release stud.
3. Slide out the release stud.
4. Insert the release stud through the
opening in the spring chamber
where the cap was removed. Insert
it into the pressure plate. T
urn the
release stud 1/4 turn clockwise in
the pressure plate. This secures
the cross pin into the cross pin
area of the pressure plate and
locks it into the manual release
position.
5. Assemble the release stud washer
and nut on the release stud.
