Using Couplers

causym CAUTION: The hydraulic system has a maximum pressure of 20000 kPa (200 bar; 2900 psi). For your protection and to assure proper function of the system, use only genuine John Deere parts.

Couplers allow hydraulic hoses to be removed without loss of oil, even under pressure.

Deluxe couplers allow hydraulic hoses to be installed as well as removed without loss of oil, even under pressure. If a malfunction or accident causes the hose to break loose from the coupler, the oil flow through the coupler is stopped immediately.

To install the hose, push it firmly into the coupler. The corresponding SCV control lever must be moved to neutral.

NOTE: When the control lever is pushed forward (or to the right on the multi-function lever), pressure is applied to the upper coupler.

Pull hose to disconnect.

Oil that escapes from the couplers when hoses are installed or removed flows through lines (A) to an oil reservoir. Drain oil reservoir if it becomes full. Do NOT reuse leak-off oil.
