WARNING
!
When working on air system
components the following precautions
should be observed.
1. Stop engine when working under a
vehicle. Always block the vehicle
wheels to prevent a fore or aft roll.
Bleeding off system pressure may
cause the vehicle to roll. Keep
hands away from brake chamber
push rods and brake adjusters; they
may apply as system pressure
drops.
2. Never connect or disconnect a hose
or line containing air pressure. It
may whip as air escapes. Never
remove a component or a pipe plug
unless you are certain all system air
pressure has been exhausted.
3. Never exceed recommended
working air pressure and always
wear safety glasses when working
with air pressure. Never look
directly into component ports or
direct a pressurized air flow
at anyone.
4. Never attempt to disassemble a
component until you have read and
understood all recommended
procedures. Some components
contain powerful springs and injury
can result if not properly
disassembled. Use only proper tools
and observe all precautions
pertaining to the use of those tools.
