Umarex Notos regulator adjustment?

Anything is possible. Empty tank. Unscrew tube out. Behind tube is the reg. Unscrew the reg out. Face of reg have a nut. Loosen it and turn reg clockwise. You won't know what the pressure is unless you put everything back. If pressure too still too hight. Repeat till you get where you want.

the regulator almost always stays in the air tube when i took my tube off the gun. you can get it out by using something like a pvc pipe with a smaller outer diameter than the air tube to push it out from inside the air tube without damaging threads or o-rings.
