Question

For truck drivers, what is Governor Cut-Out and in? How do I build air pressure?

Answer 1

Revs build presure m8

Answer 2

A governor cut-in and out controls how much air pressure is

built up in your air tanks. pressure will build up if you tanks have less than 100psi and cut-out (not build air pressure) at 125. Unless you have an air leak you can build pressure by having your truck in neautral and applying steady pressure on accelarator.
