Couplers

LX1030798-UN-29JAN03

The hydraulic system has a maximum system 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 or uncoupled without loss of oil, even when there is pressure at the coupler.

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.

To disconnect the hose, give it a firm pull.
