There's no cookie-cutter, one-size-fits-all approach to eliminating roadblocks to and problems encountered during the execution of what one might have intended to be a prime example of best-of-class industrial maintenance. Quite simply, things go awry. You dismantle it, replace the worn parts, reassemble the thing, push the button, and all you end up doing is fill the room with acrid smoke that triggers the fire alarm system. One could air a comedy series based on that premise. As they say in the real world, however, "It would be funny if it wasn't happening to me."
