Pressure Release Detent Adjustment

 

The detent adjustment screw (1) located on the rear of

the valve, may be adjusted to vary the system pressure

 

required to return each lever to the neutral position..

 

To adjust, loosen the jam nut and rotate the screw clockwise to increase the release detent pressure.. A variable pressure flow meter should be used to slowly raise the system pressure to accurately set each detent.. The adjustment should be made by your authorized Buhler Versatile dealer..

NOTE: The factory pressure release detent setting is 150 bar (2175 PSI).

WARNING: ONLY ADJUST THE SCREW WHEN THE

 

REMOTE CONTROL LEVERS ARE IN NEUTRAL AND

 

THE TRACTOR IS SHUT OFF.

Hydraulic Quick Couplers

Each remote valve section has a pair of hydraulic quick couplers located at the rear of the tractor.. These are color-coded with the hydraulic control levers in the cab.. The couplers are self-sealing and leverless and require no tools for connecting and disconnecting hoses.. The couplers also permit hoses to detach themselves from the coupler should an implement become disconnected from the tractor..

The left section couplers (2) are identified by an “extend/raise” symbol on the couplers dust cover and the right section (3) are identified by a “retract/lower” symbol on the couplers dust cover..

Excess oil drain hoses (4) are attached to each coupler to drain away oil released during connection and separation of the couplers..

The couplers will accept standard (1/2") SAE or ISO tips.. The couplers can be connected or disconnected under pressure..

Coupler Connection

1.To connect couplers, wipe the outside tip of the coupler to remove any dust and minimize contamination..

2.Swing the dust cover (5) aside and insert the hose into the coupler, making sure the hose is properly seated..
