A steris service technician arrived onsite to inspect the harmony connectpoint and spoke with facility personnel regarding the reported event.Facility personnel confirmed that following a patient procedure a nurse attempted to adjust the location of the connectpoint arm when she felt a "prick" from the top portion of the brake screw.The technician inspected the connectpoint arm and noticed a burr on the top portion of the brake screw which caused the reported event to occur.Upon further follow-up with facility personnel the technician learned that earlier that day the facility's maintenance team attempted to tighten the brake screw without first loosening the other three screws as instructed in the operator manual.The root cause of the burr can be attributed to facility personnel overtightening the brake screw.The technician replaced the friction brake assembly including all screws, tested the connectpoint, confirmed it to be operating according to specifications, and returned it to service.The technician counseled facility personnel on proper preventive maintenance activities for their harmony connectpoint, specifically how to adjust the brake screw.No additional issues have been reported.
