WARNING! Your brakes could fail if you con-
tinue driving with deflated air springs. Air
escaping from the system will lower the air
pressure, which could cause a spring brake to
engage. The spring brake may cause your
brakes to drag and burn up the linings. If you t
continue to operate in this condition, a fire
may result which will result in equipment
damage, death or personal injury.
You can get to a repair facility if you do the following:
1. Remove the height control link connected to the axle
and to the suspension air valve control arm. This will
cause the air valve control arm to center in the closed
position.
2. The air system can then be pumped up to normal
pressure for continued operation.
WARNING! Low air pressure could make the
brakes unsafe for driving which can lead to
death or personal injury. Before driving the
vehicle, make sure the pressure does pump
up to over 100 psi for normal brake operation.
If the air pressure does not pump up to at
least 100 psi, don’t try to move the vehicle.
CAUTION: Operating a vehicle with air sus-
pension bags either overinflated or underin-
f l a t e d m a y c a u s e d a m a g e t o d r i v e li n e
components. If a vehicle must be operated
under such conditions, do not exceed 5 mph.

Coasting
WARNING! Do not coast with the transmis-
sion in neutral or with the clutch pedal
depressed—it is a dangerous practice. With-
out the use of the retarding power of the driv-
etrain, your vehicle can reach dangerous
speeds. At very high speeds you may not be
able to put the transmission in any gear. At
high speeds you could seriously damage your
vehicle or cause an accident when you put the
transmission in gear. The engine speed could
exceed the maximum governed speed and
