Removing Hydraulic Cylinders

causym CAUTION: Escaping fluid under pressure can penetrate skin causing serious injury. Avoid 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 in skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury may call Deere & Company Medical Department in Moline, Illinois, or other knowledgeable medical source.

causym CAUTION: If wing cylinders must be removed with wings in folded position, be sure to chain wings together to prevent wings from falling on by-standers. Before reinstalling, cylinder must be fully charged with oil. (See INSTALLING AND BLEEDING WING-FOLD CYLINDERS in this section.)

1. Fully lower machine and wings (if equipped) and standards.

2. Shut off tractor engine and move hydraulic levers back and forth to relieve pressure.

3. Disconnect hoses at tractor and from cylinder ports. Cover tractor outlets, cylinder ports, and hose ends.

4. Unpin cylinder(s). Check, and repair, if necessary. See your John Deere dealer.
