I started a little woodworking business and bought a stationary air
compressor. Its a Husky sold at Home Depot, I think made by CH. When I
start it the pressure goes to 140 psi before it shuts off, I want to
reduce this cut off to around 90. It comes with no adjustment knob but
Home Depot people said it can be preset by adjusting something inside,
of course HD people don't know what that something is. I actually like
the fact that it has no knob, this way my employees won't fiddle around
with it.

The adjustment thingie is likely inside part 9 of this diagram.

I am quite handy and would like to experiment, though I need some hints
on how to go about it. Any clues?
