Connecting Cylinder Hoses

causym 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.

1. Remove dust caps (if equipped) from hose end.

2. Pull dust plug from couplers (A, B, and C).

3. Make sure hose end and coupler receptacles are clean.

4. For double-acting cylinders, check hoses to see which is used for extending. This hose must be connected to the top receptacle of coupler (A, B, or C) in order for cylinder to extend when SCV levers are pushed forward.

For single-acting cylinder, attach hose to top receptacle of coupler (B or C).
