    A - Latch Pin (1 each side)

    Prevent bodily injury or death from a falling bucket or attachment. DO NOT operate the loader without making sure that latch pins (A) are engaged with the bucket or attachment. Failure to engage pins causes the bucket or attachment to detach from the loader.

    Check pin engagement with the bucket:

    1. Position loader approximately 300 mm (12 in) from the ground and extend the bucket cylinders until the front edge of the bucket contacts the ground.

    2. Continue to apply pressure against the ground verifying pins (A) are engaged with the bucket.


  10. CAUTION:

    X9811-UN-23AUG88

    Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before connecting hydraulic or other lines. Protect hands and body from high-pressure fluids. See additional information, Avoid High-Pressure Fluids in Safety section.

    Level bucket and lower flat on the ground.


  11. Relieve hydraulic pressure. (See Relieve Hydraulic Pressure in Controls section.)
