Couplers

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 uncoupled without loss of oil, even under pressure.

Furthermore, DeLuxe couplers allow hydraulic hoses to be coupled as well as uncoupled 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 connect the hose union, press it firmly into the coupler. In the case of standard couplers, the corresponding SCV control lever must be moved to neutral.

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.

Oil which escapes from the couplers when hoses are connected or removed flows via lines (A) to an oil reservoir. Drain oil reservoir if it becomes overfull. Do NOT re-use leak-off oil.
