NOTE: To help identify and properly connect hoses, (AR103808) Hose Identification Kit is available from your John Deere dealer.

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.

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

5. Remove caps from port connectors and attach hoses to "FOLD", "UNFOLD", "LEVEL PISTON", and "LEVEL ROD" ports. Refer to Hydraulic Hose Diagram in this section for correct hose-to-valve port connections.
