    Bleeding Trim Tabs-gctid808586

    I replaced the lines going to the trim tabs because they were cracked and looked like they would go at any minute. When I did that the fluid came out of the cylinders which I expected but when I powered the system back up, I hear the pump working the well is full and I don't see the tabs moving. According to the manual all you have to do is fill the reservoir and keep trying to lower and raise them until they fill and move. I would hate to keep doing it and burn out the pump. Has anyone bled the system and then primed it up again? It seems like it should have worked the way I did it but its not for some reason.


    Did this myself not that long ago. Yes, running pump up/down several times should bleed out any air. I actually took my actuators apart to clean any debris out of them and flush the lines

      No need to bleed air from the lines or actuators. Simply operating the pump and actuators in/out multiple times will cause them to self-purge.

      Be sure to keep the reservoir up to snuff.

        That's what I thought, I didn't think it was very complicated. I will try it this weekend if weather permits. Thanks.
