WARNING! PLEASE READ AND FOLLOW

THESE INSTRUCTIONS TO AVOID PERSONAL

INJURY OR DEATH:

When working on or around a vehicle, the following

general precautions should be observed at all times.

1. Park the vehicle on a level surface, apply the

parking brakes, and always block the wheels.

Always wear safety glasses.

2. Stop the engine and remove ignition key when

working under or around the vehicle. When

working in the engine compartment, the engine

should be shut off and the ignition key should be

removed. Where circumstances require that the

™

VALVE

engine be in operation, EXTREME CAUTION should

be used to prevent personal injury resulting from

contact with moving, rotating, leaking, heated or

electrically charged components.

3. Do not attempt to install, remove, disassemble

or assemble a component until you have read

and thoroughly understand the recommended

procedures. Use only the proper tools and observe

all precautions pertaining to use of those tools.

4. If the work is being performed on the vehicle's

air brake system, or any auxiliary pressurized air

systems, make certain to drain the air pressure

from all reservoirs before beginning ANY work

on the vehicle. If the vehicle is equipped with an

AD-IS

air dryer system or a dryer reservoir module,

be sure to drain the purge reservoir.

5. Following the vehicle manufacturer's recommended

procedures, deactivate the electrical system in a

manner that safely removes all electrical power

from the vehicle.

6. Never exceed manufacturer's recommended

pressures.

7. Never connect or disconnect a hose or line

containing pressure; it may whip. Never remove

a component or plug unless you are certain all

system pressure has been depleted.

8. Use only genuine Bendix

components and kits. Replacement hardware,

tubing, hose, ﬁ ttings, etc. must be of equivalent

size, type and strength as original equipment and

be designed speciﬁ cally for such applications and

systems.

9. Components with stripped threads or damaged

parts should be replaced rather than repaired. Do

not attempt repairs requiring machining or welding

unless speciﬁ cally stated and approved by the

vehicle and component manufacturer.

10. Prior to returning the vehicle to service, make

certain all components and systems are restored

to their proper operating condition.

11. For vehicles with Antilock Traction Control (ATC),

the ATC function must be disabled (ATC indicator

lamp should be ON) prior to performing any vehicle

maintenance where one or more wheels on a drive

axle are lifted off the ground and moving.
