Claim 6:
7. The apparatus of claim 1 wherein:
the first displacement mechanism further comprises a first latch operable to engage a latching feature of the gas lift mandrel to thereby cause the first displacement mechanism to move the first holder from the retracted first holder position to the extended first holder position;
the second displacement mechanism further comprises a second latch operable to engage the latching feature of the gas lift mandrel to thereby cause the second displacement mechanism to move the second holder from the retracted second holder position to the extended second holder position; and
when the first holder is in the retracted first holder position and holds the used gas lift valve, the interlock mechanism is operable to permit the second latch to engage the latching feature of the gas lift mandrel to thereby permit the second displacement mechanism to move the second holder from the retracted second holder position to the extended second holder position.
