I assume this one is relieving because when I reduce the pressure to the arm the excess pressure bleeds off when turning the adjustment knob. Is that correct? </div><div>Also to anyone with an opinion, the air system regulator for compensation to the arm is literally 1 foot from my side positioning thruster. This makes me think I should air compensate that thruster instead of oil. The system works with a small 3L air holding tank that is maintained at 300 psi from the main HP tank. I am not sure if I should risk feeding the thruster from the small tank, in case the thruster seal leaks it could cause the arm to flood. </div><div>Hank</div><br></div></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>Personal_Submersibles mailing list</span><br><span><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br></div></blockquote></body></html>
