Hydraulic Test Ports
The hydraulic test ports provide an easy and convenient
means of checking pressure for the ve main functions
of the paver: Forward drive (left and right sides),
conveyor, charge pressure and the main manifold valve.
The test ports are located together on the left side
beneath the steering control box. (Figure 5-47)

Function PSI Relief / Gauge
1 Left Forward
Relief set at 3625 PSI.
Use 4000 PSI gauge.
2 Right Forward
Relief set at 3625 PSI.
Use 4000 PSI gauge.
3 Conveyor
Relief set at 3400 PSI.
Use 4000 PSI gauge.
4 Charge
Relief set at 25 - 400 PSI.

To check pressure:
1. Using the table above, connect the appropriate
gauge to the port being tested.
2. Start the engine, then check gauge for the proper
pressure reading.
3. If adjustment is needed, locate the pressure-
reducing valve on left side of main manifold.
4. Remove valve cap with an allen wrench.
5. Adjust the pressure-reducing valve clockwise for
more tension or counterclockwise for less tension.
