TS75 Horrible Cut From New

[Refrus]

I have a Ts75 that a bought about 4 years ago.
I bought the saw, took it to site and first cut, it felt like it would bind up in the cut.
I took it back to the shop and they sent it to festool.
This was the first of many trips to festool to resolve this issue.
The shop in Sydney I bought it from eventually asked me to deal with the rep directly.
I did.
The saw went off to Melbourne again to "get fixed ".
It came back with the same issue.
I have taken cuts with the rep there and asked him to take cuts. I've bought new blades, always used dust extraction,  always used a full track and nothing changes.
I have been using makita and straight edge because I can't risk ruining the expensive peices I'm cutting.

Sorry for the long rant but can anyone give me suggestions as to how to fix this saw?

Refrus.

The only thing I can think is that the tracking is way off.

With the power lead disconnected, latch the blade halfway down as if you were changing the blade.  Turn it upside down and put a track on it.  See if the gap between the splinter guard and the blade teeth is the same front and back.

Otherwise I'm out of ideas.

To clarify what was said above, the blade must be parallel to the track/direction of travel.  If the leading edge is toe’d out, you can get some binding.  There are adjustment screws similar to the procedure on the TS55 to correct for this.  You can search this forum for the TS55 supplemental manual which outlines the procedure and verify your saw has the same adjustment screws.

Also get a straight edge and confirm your guiderail is straight.

In addition to what raj said also check the cams that adjust the fit on the guide rail. I had a similar problem with my TS75 you would get about halfway to 3/4 through a cut and the saw just wouldn’t want to go any farther.

The front adjusting cam was somehow vibrating tighter and the saw was getting too tight on the rail. I tightened the screw fastening it and problem solved.

That is my thoughts too.

Festool has had the saw about 6 times with this same complaint and they hand it back each time swearing its running true.
I'll do as you suggest and break out the dial indicator.

I'll check the alignment and have a read.

I have used multiple guide rails other than mine and the cut is always a dogs breakfast.

I will check the screw tightness.
Thank you.
Rep had a try at adjusting everything and the cut was always disgusting.
Fingers crossed that is it.

Just curious...Did you ever get this resolved.

Ive had a similar issue with my TS 75 EQ. It has been cutting rough for a long time, especially in thicker stock like 1.5" table tops. I would get burning and blade "gouges" in the cut. I tried swapping rails, blades, checking alignment of the blade to base. I got out the dial gauge recently out of frustration when we were cutting some stair trends and getting a literal curved cut. Turns out the blade is cupping when tightened, i checked the blade in and out of the saw, even with another spare blade I had. Both blades were dead flat when checked with a precision straight edge, and a clearly visible cup of about 1/64th when installed on the saw. I'm going to try replacing the clamping flange and see if that works.

Cupping of the TS75 blade!!??  Does not seem like an easy thing to do.  Did a new flange do the trick?
