Engaging the bypass function
Test bypass function with pump installed on machine. The bypass function is engaged by unscrewing the
bypass valve. Do not open the bypass valve when machine is operating.
1. To engage the bypass function, use a 5/8 hex wrench to unscrew the bypass valve. Rotate the bypass
valve approximately three turns counterclockwise. Do not rotate more than 3 revolutions, as
additional rotation will permit external leakage.
2. To close the bypass valve, rotate the bypass valve clockwise until seated. Torque to 20 N•m [15 lbf•ft].
3. If machine is towable with bypass valve opened three turns, and if wheels are locked (not towable)
with bypass valve closed, bypass function is working correctly.
