parts in the gear. This could result in worn
components. The mixture of two different
fluids, although harmless to individual
internal components, may initiate a
chemical reaction that produces a new
compound that will attack seals and other
internal components. Do not mix different
fluids.
What is the Air System?
Important safety information about your
vehicle's air system.
The operation of the vehicle’s braking
system and many vehicle accessories
depends upon the storage and application
of a high-pressure air supply.
WARNING!
Do not attempt to modify, alter, repair or dis-
connect any component of the air system.
Repairs or modifications to the air system,
other than what is described in this section,
should only be performed by an authorized
dealer. Failure to comply may result in death
or personal injury.
WARNING!
Prior to the removal of any air system com-
ponent, always block and hold the vehicle
by a secure means other than the vehicle's
own brakes. Depleting air system pressure
may cause the vehicle to roll unexpectedly
resulting in an accident causing death or
personal injuries. Keep hands away from
chamber push rods and slack adjusters,
they may apply as system pressure drops.
WARNING!
After completing any repairs to the air sys-
tem, always test for air leaks, and check the
brakes for safe operation before putting the
vehicle in service. Failure to comply may re-
sult in death, personal injury, equipment or
property damage.
WARNING!
Never connect or disconnect a hose or line
containing air pressure. It may whip as air
escapes. Never remove a component or
pipe plug unless you are certain all system
pressure has been depleted. Failure to com-
ply may result in death, personal injury,
equipment or property damage.
WARNING!
Never exceed recommended air pressure
and always wear safety glasses when work-
ing with air pressure. Never look into air jets
or direct them at anyone. Failure to comply
may result in death, personal injury, equip-
ment or property damage.
WARNING!
Never attempt to disassemble a component
until you have read and understood recom-
mended procedures. Some components
contain powerful springs and injury can re-
sult if not properly disassembled. Use only
proper tools and observe all precautions
pertaining to use of those tools. Failure to
comply may result in death, personal injury,
equipment or property damage.
