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 equipment damage.

  • 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 lying 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.
Minimum SW Requirement

For robots with joint size 5, a minimum of SW version 10.12 is required. Upgrade to version 10.12 or newer before installing or replacing the joint.
