Connecting Implement Hydraulic Hoses—Mechanical SCV

CAUTION:

X9811
X9811-UN-23AUG88

Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure. Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.

If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A.

IMPORTANT: Avoid damage! To prevent contamination of female quick couplers, install color-coded hose ends on couplers when not in use.

  1. Park machine safely.

  2. Relieve hydraulic pressure:

    • Move dual selective control valve (SCV) lever rearward-to-forward and side-to-side several times.
    • Move third SCV lever rearward-to-forward several times if equipped.
    • With the key switch on, activate the third SCV upper and lower switches several times (if equipped).

  3. See your implement operator’s manual for specific instructions on connecting hydraulic hoses to couplers. Install hose ends in couplers with matching colors.

    • Colors for the couplers are shown on the label installed on the machine near the couplers.

  4. See your implement operator’s manual for specific instructions on operating SCV controls.
