Hello, I have a Stihl HT-75 pole pruner. I recently re-powered it with a FS-110R trimmer power head. Runs purrfict! The Problem is, wanting More! trying to reach a little further than what is allowed, by telescoping it until it came apart. I field stripped it!!! There are collars? springs and shafts to line up. Wrong thing to do. Now I cannot get it back together properly. It will work, but will not retract all the way down. Is there a downloadable manual out there to help assist in reassembly? Any words of wisdom? This is probably a simple fix, put it back together, problem is I cannot remember how it goes back together. thanks in advance, kenny.
