  - (2) **Operation and maintenance.**

      (b) For jacks sent out of shop for special work, when sent out and when returned,

      (c) For a jack subjected to abnormal load or shock, immediately before and immediately thereafter.

    - (vii) Repair or replacement parts shall be examined for possible defects.
    - (viii) Jacks which are out of order shall be tagged accordingly, and shall not be used until repairs are made.
