Air system is crucial for the brakes to
operate with maximum efficiency. All
air tanks on the chassis must be
drained after each working day.
Figure 177. Air tank
Some units are equipped with an air
dryer and/or alcohol evaporator
(Figure 177. “Air tank”). These devices
are used to reduce water in the air
system, preventing air components to
rust or to freeze in cold weather.
To perform maintenance on the air
dryer and alcohol evaporator, refer to
the chassis manufacturer maintenance
manual.
The main hydraulic valve which
controls the body functions, is
activated by air actuators (Figure 178.
“Air actuators”). When the tailgate or
body lever on the console is moved, air
pressure passing through the lever will
activate the corresponding air actuator
on the main valve; resulting in a
movement of the hydraulic spool inside
the valve.
The same thing occurs when the
packer is activated; when pressing the
green button on the packer control
station, an electric signal is sent to the
air-valve that controls the actuator on
the main hydraulic valve. Refer to Air
System section for air diagrams.
