Event: Line Oiler Tank Pressurize

1. Ensure that the truck brake system has the correct air pressure before proceeding.

2. Air pressure flows through Air Filter (55) and oil is injected into the system as it flows through Oiler (56).

3. When the Directional Control Valve (58) is positioned to the “On” position, pressurized air flows through Pressure Reducing Valve (52.1).

4. Pressure exceeding the spring setting of the Pressure Reducing Valve (52.1) will cause that valve to shutoff and not allow the pressure to exceed the setting.

5. Air pressure can be viewed at gauge (47.2).

6. Reduced air pressure then flows through check valve (49) and passes through the Flow Control Valve (68) which pressurizes the Line Oiler Tank (41).
