Introduction
The diverter flow valves will divert flow from the inside wheel to the outside wheel in order to allow the outside wheel to turn faster than the inside wheel. Diverting the flow greatly reduce tire scrubbing and allows for optimal turning.
Note: Prior to performing this test, the Testing and Adjusting, "Hydraulic System Pressure - Test and Adjust" must be performed.
Machine Preparation
- Clear all personnel from the machine and from the area around the machine.
- Start the engine.
