When working on or around air brake systems and components, the following precautions should be observed:
1. Always block vehicle wheels. Stop engine when working under a vehicle. Depleting vehicle air system pressure may cause vehicle to roll. Keep hands away from chamber push rods and slack adjusters; they may automatically 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 pipe plug unless you are certain all system pressure has been depleted.3. Never exceed recommended air pressure and always wear safety glasses when working with air pressure. Never look into air jets or direct them at anyone.4. Never attempt to disassemble a component until you have read and understand 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 use of those tools.5. Use only genuine OEM replacement parts and components. A. Only components, devices, mounting and attaching hardware specifically designed for use in air brake systems should be used.B. Replacement hardware, tubing, hose, fittings, etc. should be of equivalent size, type, length, and strength as the original equipment.C. Make certain that when replacing tubing or hose, all supports, clamps or suspending devices that were originally install by the vehicle manufacturer are reinstalled.6. Devices with stripped threads of damaged parts should be replaced. Repairs requiring machining should not be attempted.7. When working in the engine compartment, the engine should be shut off. Under circumstances where it is required that the engine be operating, EXTREME CAUTION should be used to prevent personal injury resulting from contact with moving, rotating, leaking, heated or electrically charged components.
