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
air 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.
