118 Maintenance

Check Valves

Follow the procedure below to check out the

air tank check valves at least once a year.

This is to see if air pressure is maintained in

the tanks when the air pressure is depleted in

the supply tank (wet tank).

Note: The check valves should be checked

at least once per year.

1 Chock the rear wheels.

2 Let the compressor build up air pressure

to the governor cut-off.

3 Bleed the air pressure from the supply

tank (wet tank).

4 Check the air pressure gauges on the

instrument panel to see if the pressure

is maintained in both primary and

secondary air tanks.

5 Any bleed-off from one or both of the

tanks indicates a defective check valve;

replace valve.

6 Repressurize the system and remove the

wheel chocks.

WARNING

To prevent personal injury, always

drain the air supply from the vehicle

before attempting to repair or replace a

component. Wear eye protection and take

care not to get fingers caught in the slack

adjusters when spring brakes are applied.

WARNING

Always wear appropriate eye protection

to prevent the risk of injury due to contact

with engine debris or fluids.

DANGER

Before working on or inspecting the

vehicle, set the parking brakes, place the

transmission in neutral and block the

wheels. Failure to do so can result in

unexpected vehicle movement and can

cause serious personal injury or death.

DANGER

Compressed air components can separate

violently during disassembly if air

pressure is present. Before servicing any

part of the brake air system, completely

release the air pressure. Failure to do so

can result in serious personal injury or

death.
