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.

    Support cylinders on wooden blocks, so rods can extend and retract without interference.


  2. CAUTION: If cylinders are not bled as described, wings could drop unexpectedly, causing injury or death.

    Bleed air from system.

    1. Connect hoses to tractor.
    2. Fully extend and retract all cylinders at least two times, maintaining hydraulic pressure at full extension for at least 30 seconds.
    3. Extend cylinders again, maintaining pressure at full extension for one minute to allow all air to escape from cylinders.

  3. CAUTION: To avoid injury or death, stand clear of machine when wings are being folded or unfolded. Mechanical or hydraulic failure can allow wings to fall rapidly, causing injury or death.
