I recently picked up the parallel guide to use with the TS55, this is the one that attaches to the saw not the parallel guides that attach to the track. I used it for the first time today and the saw was getting hung up once I got into the cut and I couldn't figure out why. I thought the hose was snagging but it wasn't. Turns out the piece of black plastic, highlighted in the attachment, was sticking out just enough to catch the workpiece. It was sticking out on the trailing side but I couldn't find a picture of that edge so I'm using the leading edge to show what I'm referring to. Took out a utility knife and trimmed the black plastic until it was flush and now it works fine. Just passing along the info in case someone else runs into this.
