VEHICLE RECOVERY AND SPRING BRAKES
WARNING!
Do not operate a vehicle when the
spring brakes have been manually
released. Driving a vehicle after its
spring brakes are manually released
is extremely dangerous. The brakes
may not function. Failure to comply
may result in death, personal injury,
equipment or property damage.
WARNING!
Always secure the vehicle with
wheel chocks,
chains, or other
safe means to prevent rolling be-
fore manually releasing the spring
brakes. Releasing the spring brakes
on an unsecured vehicle could lead
to an accident. The vehicle could
roll, which may result in death, per-
sonal injury, equipment or property
damage.
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. Turn
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.
