Reman Injection pump Warning sign?

[Keasbey]

Hey guys,

I just had my AAZ injection pump resealed, and it came with a warning label.. stating I should "prelube" the pump and remove the locking pin...  Is this a general warning? I never installed a "new" pump before.. but I don't think we have a lock pin on our pump, do we?
