Please refer to Low Air Alarm Turns
On on
page 2-3 for instructions on
what to
do if the air system becomes
inoperative.
NOTE
Be sure the air pressure registers
more than 100 psi (690 kPa) in both
service systems before you move the
vehicle.
NOTE
If the pressure in either or both cir-
cuits falls below 65 psi (448 kPa), a red
warning light in the gauge will turn on
and an audible alarm tone will sound
when the engine is running.
WARNING!
If the air pressure falls below 60 psi
(414 kPa), the spring brakes may stop
the vehicle abruptly which could cause
an accident resulting in death or per
-
sonal injury. Observe the red warning
lamps on the gauges. If one comes on,
do not continue to drive the vehicle un
-
til it has been properly repaired or ser-
viced. If the light and alarm do not turn
off at start-up, do not try to drive the
vehicle until the problem is found and
xed.
WARNING!
The air pressure warning light and the
audible alarm tone indicate a danger
-
ous situation: there is not enough air
pressure in the air tanks for repeated
braking and the brake system has
failed. Without the use of your service
brakes your spring brakes could sud
-
denly apply causing a wheel lock-up,
loss of control, or over-take by fol
-
lowing vehicles. This may cause an
accident resulting in death or personal
injury. Bring the vehicle to a safe stop
right away, while you still have control
of the vehicle.
