Connecting and Disconnecting Hydraulic Hoses

CAUTION: Push transport lock touch switch (A) on SCV TouchSet monitor before attaching or detaching implements to prevent implement movement and possible personal injury.

IMPORTANT: Hydraulic hoses can fail due to physical damage, kinks, age and exposure. Check hoses regularly.

Be sure hose ends are clean prior to use to minimize hydraulic system contamination.

Clean dust covers (B). Lift dust covers upward to expose coupler ports.

NOTE: Remote cylinder couplers are designated "I" through "V". "I" is the bottom coupler.

Check to be sure connection on coupler matches cylinder travel direction required.

Follow procedure on following page when connecting hoses under pressure.

CAUTION: 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.

NOTE: When installing hydraulic hoses under pressure, follow procedure listed or hose may not stay seated.
