Hi all

First I'm quite new to all this Festool thing and for that matter woodworking.  [unsure]
I have just purchased the above saw table module and installed everything ok.  But the riving knife/extension has a little lateral play in it I would like to ask if this is normal?  It is not a huge amount of movement but it has a tendency to lean slightly to one side enough to have stopped the timber feed a couple of times. I ended up clipping the vacuum hose in such a way to hold the knife vertically.
When I fitted the knife the bolt that goes through the saw body and joins the knife extension to the saw knife stopped suddenly as if the end had hit an obstruction at the far end.  So although the bolt is very tight (to whatever it is pressing on inside the saw) and the knives are joined the bolt head is not in contact with the saw body and moves with the knives.  To be fair Festool are sending a replacement knife and bolt to try but nobody I have spoken to seems to know if the knife and bolt movement is normal.
The extension knife is not bent in any way and seems to be joined tightly to the saw knife. I guess the movement comes from the saw end and this slight sideways movement is amplified by the extension.

Can anyone tell me if this is normal?  If it is the norm I would not expect that of such expensive tools.

 
I had the same question you appear to have.  Mine too on both the TS75 and TS55 on the VL moves left and right a little.  I too spoke to Festool and they told me it was normal.  For me at least the movement left and right never actually stopped the Timber on a rip, it just seemed to force the knife into line behind the blade, so maybe yours has more movement than mine.

If its wobbly enough to stop a rip that does seem wrong and so trying another knife/bot/extension maybe the answer I guess.

Thanks for the reply Mark I will report when I get the replacement parts.  I have doubts that it will work though.  I clipped the vacuum hose so as to centralise the riving knife but of course I should not have to.
Which brings me to another point, why on earth is there an oval hole on the blade guard/dust collector to fit to a round connector on the vacuum pipe?

You pay a premium price and in this case at least seem to get a bodge job! [mad]
