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 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.

NOTE: Symbols on the covers show which coupler is for "extend" and which coupler is for "retract".

To disconnect the hose, give it a firm pull.

Leak oil which escapes from the couplers when hoses are connected or removed is trapped in oil reservoir (A). Once the oil reservoir (A) is full, empty oil reservoir (A); do NOT use the leak oil again.
