Used to follow OEM manuals to the letter, now I just adapt on the fly

Honestly, for the first 8 years in the trade I wouldn't touch a single adjustment without the MCE or GAL book open. Then last year a senior mechanic in Denver told me to just feel the door tension and set the limit switches by ear. Tbh I thought he was full of it until I tried it on a Schindler 330A and it ran smoother than ever. Ngl I still check the manual for anything code related, but for basic tuning I trust my hands way more now. Anyone else ever ignore the book and just go with what works?

Hell yeah, @scott.grace that story hits close to home. The thing nobody talks about is how manuals are written by engineers who NEVER have to actually service the thing in a hot, cramped machine room at 2am. They assume PERFECT conditions. But real life has dust, corrosion, voltage dips, and building settling. I've seen the "correct" fix from the book make a door run WORSE because the new part doesn't match the worn everything else around it. The real skill is knowing WHEN to trust the book and WHEN to trust your gut. And that only comes from breaking shit and fixing it yourself.

Two thousand seventeen. Buddy of mine was a commercial elevator tech in Atlanta. Had this old Otis that kept throwing ghost faults. Manual said to swap the whole door operator board. He had a gut feeling it was just a corroded limit switch wire. Bypassed the damn thing with a jumper and a prayer. Ran perfect for three years before the building got modernized. Never did tell the client what he actually did.
