Unsupported joints can fall, or be dropped, resulting in injury

  • Support joints while screws are being removed.

Failure to support the joint/s while screws are removed can result in damage to equipment.

  • Prevent the joint/s from falling while removing clamps or screws by doing any of the following:

  • Use something to support underneath the part that is coming off.

  • Disassemble the joint while it is laying down.

  • Support with lifting equipment.

Failure to test the new joint after replacement can lead to damage to property and/or equipment.

  • Always perform a joint replacement test before using a new joint. See the Joint Verification section in the Service Manual for more information.

  • Joints should be assembled in a vertical position to ensure proper mating between the joints.
