Air question/problem

[cmalueg4]

So when you get about 70ish psi it allows you to use the air horn, wipers, 6x6 switch, etc. What tells it to do that? My m931a2 currently sometimes works n sometimes doesn't. Also, how to I adjust the air pump, mine goes to high.

Frozen pressure protection valve.

Search the site, you should find plenty of threads on it.

Here one to start you off. https://www.steelsoldiers.com/threads/m923a2-not-building-pressure-past-75-psi.191668/#post-2246714

You do not need to adjust your air pressure.
