I serviced a fleet for a major trucking company at one time & one of their old timers did- in fact- perform the pre-check before his shift like clock work. He liked "his lift" & didn't like using another when his was down.

I can tell you his repairs/downtime were the least of the fleet. I brought this to mangement's attention after finding out he was getting a hard time because he refused to do any moves with his lift before the pre-check was done.

Their answer was that the pre-check was just a formality & was "only really needed- like once a week". Even with the numbers in front of them, they still didn't see it's importance.

This is the same company which broke by b**** every time a lift went down, wanting to know cost & downtime- go figure.....
