insufficient air to release the parking
brake, the spring brakes can be manu-
ally released.
WARNING! Never drive your
vehicle with the parking
brake applied. Always
release the parking brakes
prior to moving the vehicle.
Failure to disengage the
parking brakes prior to mov-
ing your vehicle could result
in excessive heat build-up in
the brake system, resulting
in a fire.

low RPM. Combinations of
engine speed and available
torque may over-power the
vehicle’s parking brakes.
