necessary because if the
transmission is driven by the
driveshaft (rear wheels on the
ground), no lubricant will reach the
gears and bearings, causing
damage to the transmission. .

If you desire to use the recovered
vehicle’s brakes, ensure that the
vehicle’s air system is connected to
that of the recovery vehicle. Ensure
that any air line that has been
removed from a driver-controlled
main differential lock is firmly
capped to prevent loss of air
pressure from the recovery vehicle
if it is supplying air pressure. If you
don’t desire to use the recovered
vehicle’s brakes, ensure that you
cage the spring brakes before
attempting to move the vehicle.

Manually Release the Parking
Brake
There may be times when there is not
enough air pressure, or the engine's air
compressor is not able to produce enough
pressure, to release the parking brakes. In
such cases, the parking brakes (or Spring
Brakes) can be manually released.
WARNING
DO NOT drive vehicle with malfunc-
tioning brakes. If one of the brake cir-
cuits becomes inoperative, braking
distances will increase substantially
and handling characteristics while
braking will be affected. You could lose
control of your vehicle or cause an ac-
cident. Have it towed to the nearest
dealer or qualified repair facility for re-
pair. Failure to comply may result in
property damage, personal injury, or
death.
