Claim 7:
8. The apparatus of claim 7 wherein:
the interlock mechanism comprises a release member, a third latch, and a linking member operatively connecting the release member and the third latch;
the third latch engages the second latch to prevent the second latch from engaging the latching feature of the gas lift mandrel; and
when the first holder is in the retracted first holder position and holds the used gas lift valve, the release member is operated to cause the third latch to disengage the second latch 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.
