I received the TS 55 track saw on March 16 and it is my first Festool. This is my 2nd track saw; my first track saw purchase was a Makita and I returned it without making a cut because the track was not flat to the work surface. The Festool track is a little better but not what I expected for this price. The Makita definitely had a hard plastic base. The Festool appears to also have a plastic base but painted to look like aluminum [mad]; is this true. The whole time I was reading the instruction manual, I was grousing about the postage stamp size drawings. Only later did I discover there is a Supplemental User's Manual on the web; shame on Festool for not telling me where to find this document. I have yet to make a cut with the track saw since when I turn on the saw it sounds gravelly (not a very technical term) and there appears to be some vibration. Do I have a defective track saw? In the process of inspecting the track saw, a small metal clip fell out of the dust collection port. Can anyone identify the clip shown in the attachment? The scale is in inches. I don't feel like I am getting off to a good start as a Festool owner.
