ADJUSTMENT OF SAFETY VALVE
NOTE: The Bendix
ST‑3
®
The pressure setting of the safety valve is stamped on the
cover wrench flat (closest to the pipe thread). The vehicle
manual may also provide the proper pressure setting.
If the setting is not known, determine the governor cut‑
out pressure setting and adjust the safety valve so that
the safety valve closes at a pressure setting somewhat
above governor cut‑out pressure setting (See "Operation"
section).
To adjust, the safety valve must be connected to an air
system with air pressure in excess of desired setting. It
is important that an accurate gauge be used to check
pressure settings while making adjustments.
safety valve is not adjustable.

GENERAL SAFETY GUIDELINES
WARNING! PLEASE READ AND
FOLLOW THESE INSTRUCTIONS
TO AVOID PERSONAL INJURY OR DEATH:
When working on or around a vehicle, the following
guidelines should be observed AT ALL TIMES:
▲ Park the vehicle on a level surface, apply the parking
brakes and always block the wheels. Always wear
personal protection equipment.
▲ Stop the engine and remove the 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 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.
▲ 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.
▲ 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 a Bendix
Bendix
DRM
dryer reservoir module, or a Bendix
®
™
AD-9si
air dryer, be sure to drain the purge reservoir.
™
▲ Following the vehicle manufacturer's recommended
procedures, deactivate the electrical system in a manner
that safely removes all electrical power from the vehicle.
▲ Never exceed manufacturer's recommended pressures.
▲ 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.
▲ 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.
▲ 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.
▲ Prior to returning the vehicle to service, make certain all
components and systems are restored to their proper
operating condition.
▲ For vehicles with Automatic 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.
▲ The power MUST be temporarily disconnected
from the radar sensor whenever any tests USING A
DYNAMOMETER are conducted on a Bendix
Advanced
-equipped vehicle.
™
▲ You should consult the vehicle manufacturer's
operating and service manuals, and any related
literature, in conjunction with the Guidelines above.
