So after several months of no use, I go to fire my Torus Pro up, and the Power Draw Bar is inop. I did some basic troubleshooting. The air solenoids are working, if I remove the line from the top of the unit and hit the button, I get about a 1 second blast of air. The unit seemed loose, so I removed the trigger wheel and tightened the large phillips machine screw underneath while simultaneously engaging it with the draw bar to insure alignment. It still doesn't seem to function. It appears that the silver cylinder that is attached to the airline is supposed to move, but mine seems like it hangs up. How do I get the PDB off the unit for inspection? I tried taking out that large machine screw which significantly looseded the unit, along with the trigger wheel, but something is still holding it on, and I don't want to break it. I sent a note to John,earlier today but I have not heard back yet. Has anyone removed one of these yet?
