I just bought the Festool TS-55 track saw and used it for the first time yesterday. First time ever using a track saw....

I am using a Rigid shop vac and Bosche hose for dust extraction.

I was cutting some 3/4 ply yesterday, taking the saw for a test drive and figuring out how to use it. I can tell I need to buy some clamps for this already..... I was holding the track to keep it from moving on me, and I felt a shock. At first I thought it was my imagination, so I had to try it again. Sure enough, damn thing bit me again, and I can actually see an arch between the saw and track. I am assuming this is a static discharge, and it's most likely due to the saw being insulated, and the hose I'm using is not, so I have become a ground path. Or, maybe my saw is defective?

Anyone else experience this? What do you recommend? It's not a mild shock either. It's got a pretty good bite to it.
