Couplers

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

Couplers allow hydraulic hoses to be coupled and uncoupled, 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 connect the hose union, press it firmly into the coupler.

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

To disconnect the hose, give it a firm pull.

Leak-off oil which escapes from the couplers when hoses are connected or removed is trapped in an oil reservoir. Drain oil reservoir if it becomes overfull. Do NOT re-use leak-off oil.
