I just picked one of these up and I think the springs are shot. I'm not 100% sure how the adjustments are made though. I know it may seem simple but I can't figure it out......probably because the springs are stretched. I know there are two adjustment "T" handles. Which one does what and which way are you turning it? I have searched all over the web with no help. I guess if nobody here knows I'll just call the company and get some help there. This thing is gonna be sweet in my backyard of my next house though.
