Introduction
WARNING
DO NOT attempt to modify, alter, re-
pair or disconnect any component of
the air system. Repairs or modifica-
tions to the air system, other than what
is described in this section, should on-
ly be performed by an authorized deal-
er. Failure to comply may result in
death or personal injury.
WARNING
Prior to the removal of any air system
component, always block and hold the
vehicle by a secure means other than
the vehicle's own brakes. Depleting air
system pressure may cause the vehi-
cle to roll unexpectedly resulting in an
accident causing death or personal in-
juries. Keep hands away from cham-
ber push rods and slack adjusters,
they may apply as system pressure
drops.
WARNING
After completing any repairs to the air
system, always test for air leaks, and
check the brakes for safe operation
before putting the vehicle in service.
Failure to comply may result 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 comply may result
in death, personal injury, equipment or
property damage.
WARNING
Never attempt to disassemble a com-
ponent until you have read and under-
stood recommended procedures.
Some components contain powerful
springs and injury can result if not
properly disassembled. Use only prop-
er tools and observe all precautions
pertaining to use of those tools. Failure
to comply may result in death, person-
al injury, equipment or property dam-
age.
WARNING
Never exceed recommended air pres-
sure and always wear safety glasses
when working with air pressure. Never
look into air jets or direct them at any-
one. Failure to comply may result in
death, personal injury, equipment or
property damage.
