Lift Axle Operation
If your unit is equipped with an air lift axle, it is nec-
essary to determine the proper air pressure required in
the ride spring bags in order to have the axle support its
correct share of the load. The procedure is described on
the Hendrickson decal, L402, which is on the inside of
the air lift control box door. It is also shown here, along
with a schematic of the entire system. It is important to
follow this procedure in order to have the axle support
its correct share of the load and also to avoid having the
tires on the lift axle lock up while braking.
