OPERATION 153
Axle air pressure should be set to provide proper weight distribution across the
chassis and to conform to local weight regulations. In general, a setting of 60
to 70 psi is adequate for most applications, but an accurate setting should be
determined by weighing the axles and adjusting the air pressure accordingly.
Adjustable air regulators are located inside the cab to adjust tag and pusher
axle air pressure. Pressure is regulated by turning the knob until the proper
pressure, as indicated by the accompanying pressure gauge, is reached. Turn
the air regulator knob clockwise to increase pressure, or counterclockwise
to decrease pressure.
