Using Pressure Free Return Circuit

This connection ensures a pressure free oil return.

Examples of implements which cannot withstand high pressure in the return line:

• Hydraulic motors which have a pressurized oil return. Failure of the motor housing or shaft seals may result if the return line is pressurized.
• Remote hydraulic valves located on the implement may allow unexpected movement of cylinders if the return port is pressurized.

When the pressure free return circuit is not used, use the protective dust cap.
