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.

4. Move levers to relieve hydraulic pressure.

causym CAUTION: Help prevent personal injury caused by unexpected loader movement. Anticipated loader movement responds to control lever only if hoses are connected correctly.

5. Connect hoses using colored dust caps to match hoses to couplers.

NOTE: Hoses connections are identified by matching the colored cap on the hose end with the same colored plug on the control valve coupler. If caps are missing, see IDENTIFYING HOSE CONNECTIONS in Service section for replacements.

Tractors without mid-couplers only; Install hose bracket (A) under foot platform and fasten with spring pin (B).
