Finally got the call back on that tricky Schindler 330A door operator
I keep seeing guys set the closing force way too high on those units, like over 150 Newtons, just to make sure it shuts. That puts crazy stress on the hanger rollers and the track. After adjusting three different ones in the downtown high rise last month to the book spec of 100N, the call backs stopped. Anyone else notice this specific issue with that model?

That 150N number is a perfect example. It's like people think more force is always the answer, but it just breaks things faster. I see it all the time with gate latches and even cabinet doors in my line of work. Cranking something to its limit to solve a simple problem, like a sticky track, just guarantees a bigger repair later. Your fix proves the manual usually knows best.

@james_campbell12 I used to crank things too, but this changed my mind.

Man, that's a great point. I used to be guilty of the same thing, just cranking up the force to get a door to behave. It feels like a solid fix in the moment. But seeing how much longer things last when you actually follow the book specs is a real eye opener. It just proves that the quick and dirty fix usually costs more time down the road.
