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.

Plug hose into extend side of coupler (C).

Plug hose into retract side of coupler (D).

Follow the procedure on next 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.

IMPORTANT: When installing hydraulic hoses under pressure, follow this procedure or hoses may not stay seated.

Push extend hose (A) forward until contacting coupler.

Pull back on lever (B) while continuing to push forward on hose. This will allow coupler poppet to retract.

With hose fully inserted into coupler, release lever allowing it to go back to the center position. This will lock hose in place.

Push retract hose (C) forward until contacting coupler.

Push forward on lever (D) while continuing to push forward on hose. This will allow coupler poppet to retract.

With hose fully inserted into coupler, release lever allowing it to go back to the center position. This will lock hose in place.

Move SCV switch to neutral position with no time flow "commanded".

Release extend hose (A) by pulling rearward on lever (B).

Release retract hose (C) by pushing forward on lever (D).

To relieve hydraulic pressure in implement, move SCV control switch down and forward to float position (E), while engine is running.

Turn dust cover back over SCV receptacle.
