! 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 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.

plastic or brass hammer to loosen. Lift cover off.
