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

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

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, fittings, etc. must be of equivalent

size, type and strength as original equipment and

be designed specifically 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 specifically 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.

PREVENTIVE MAINTENANCE

Important: Review the Bendix Warranty Policy before

performing any intrusive maintenance procedures. A warranty

may be voided if intrusive maintenance is performed during

the warranty period.

No two vehicles operate under identical conditions, as a

result, maintenance intervals may vary. Experience is a

valuable guide in determining the best maintenance interval

for air brake system components. At a minimum, the QR-L

valve should be inspected every 12 months or 3600 operating

hours, whichever comes first, for proper operation. Should

the QR-L

™

valve not meet the elements of the operational

tests noted in this document, further investigation and service

of the valve may be required.

SERVICE CHECKS

1. Remove any accumulated contaminants. Visually

inspect the valve's exterior for physical damage. Replace

the valve if excessive physical damage is noted.

2. Inspect all air lines connected to the valve for signs of

wear or physical damage. Repair or replace as

necessary.

OPERATIONAL AND LEAKAGE TESTS

1. Block the vehicle's wheels and fully charge the air

system.

2. Apply and release air pressure rapidly to the QR-L

several times and check for prompt response.

3. With air pressure applied to the supply port, apply a

soap solution to the QR-L

™

of a 1" bubble in 5 seconds is permissible.

4. With the brakes still applied to the supply port, apply a

soap solution around the valve where the cap and body

are joined. No leakage at this point is permitted.

If the valve does not function as described, or if leakage is

excessive, replace it at any authorized parts outlet.

REMOVAL

1. Identify and mark or label all air lines and their

connections to the QR-L

air lines. Use the QR-L

the air line or fitting being removed.

2. Remove the QR-L

mounting hardware, if any.

INSTALLATION

™

1. Install the QR-L

hardware, if any, saved during removal.

2. Reconnect all air lines to the valve using the identification

made during removal. Note: An arrow embossed in the

body of the vale indicates the direction of air flow and

points toward the delivery port. Use the QR-L

wrench flat, closest to the air line or fitting being installed.

3. Test all air fittings for excessive leakage and tighten as

needed. Perform OPERATIONAL AND LEAKAGE

TESTS before placing the vehicle back into service.

NOTE: The construction of the QR-L

and cannot be repaired. If the QR-L
