I recently installed the handle and boom arm on my CT22. It's a great upgrade and it certainly does what it's supposed to do - keep the hose from getting in the way.
My only problem with the boom is when moving the unit around the shop the outriggers Festool provides to keep the unit from tipping backwards catches on anything that gets in its way. I'm considering removing the outriggers and mounting a counter-weighted systainer to the unit in hope of solving this problem. Am I on the right track or is there another solution to the problem that my engineering-challenged mind has not thought of.
