The 4th pedal circuit needs to be modified on certain 320B, 322B, 325B, 330B and 345B Excavators. When the auxiliary backup switch is placed in the manual/backup position, the auxiliary controller is disabled. When the auxiliary controller is disconnected, the entire auxiliary system should be disabled. With the current configuration of components, the auxiliary control pedal (Illustration 1) is still active. In the current configuration, if the auxiliary controller is disconnected and the 4th pedal is pressed, full hydraulic flow will enter the auxiliary implement tool circuit. The full hydraulic flow may cause extreme damage to the tool.
