RE: Robart air up/spring down retracts won't lock down
Edwin,
I agree. Rolling Thunder from FG (who had the same problems) told me he called Robart and they replaced the air up/spring down cylinders with air up/air down cylinders. Same retract unit, changed cylinders only. If I don't get this problem solved soon, I believe that is what I'm going to try. I assume I would have to get a different air valve.
