Air Tanks
WARNING
If the supply and service air tanks are
not drained at the recommended fre-
quency, water could enter the air lines
and valves. This could cause corrosion
or blockage, which could compromise
the brake system safety and potential-
ly cause an accident. Failure to comply
may result in property damage, per-
sonal injury, or death.
CAUTION
DO NOT use penetrating oil, alcohol,
brake fluid, or wax-based oils in the air
system. These fluids may cause se-
vere damage to air system compo-
nents.
To eject moisture from the air system
tanks, pull the line that is connected to the
moisture ejection valve. Continue pulling
until the air comes out free of water.
Daily
The supply and service air tanks, must be
drained on a daily basis. Operate air
devices daily to circulate lubricants within
the unit.
Periodically
Clean filter screens ahead of the valves by
removing the screens and soaking them in
solvent. Blow them dry with pressurized air
before reinstalling them.
• Maintain the air compressor to
prevent excessive oil bypass
• Replace worn seals in valves and
air motors as they are needed.

Air Gauges and Air Leaks
WARNING
DO NOT operate the vehicle if leakage
in the air system is detected. Conduct
the following procedure and contact an
authorized dealer (or any other proper-
ly equipped service center) if a leak is
detected. Failure to check the brakes
or follow these procedures could
cause a system failure, increasing the
risk of an accident and may result in
personal injury, property damage, or
death.
If your vehicle is equipped with air brakes,
it has two separate, additional air systems:
Primary and Secondary. Each air system is
monitored by a gauge indicating system
pressure in either pounds per square inch
(psi), and/or kilopascals (kPa).
