First question I have is who are you, you did not fill out your profile are you a Contractor, Owner of equipment, Project manager?
The reason is each one will have a different reason for asking this question.
As the owner/customer my answer is no, not worth the risk.
As the PM my answer is no, the delay is better than the risks.
As the EC my answer is hell no, if it has an issue later on not worth the risk of you being on the hook for lost down time once building is running.
Even if it tests and powers up now once it start vibrating later it may wear thru or after it is fully loaded and heats up it may fail.
Your choice but whoever is footing the bill is paying for NEW equipment, not a repaired piece.
