Festool TS75 resonating sound and shaking

[Serge]

Hello,

I recently purchased a Festool TS75, mostly cutting 2" hardwoods,  it vibrates, resonates and shakes allot when cutting.
I also cut 2" Douglas Fir, and it vibrates the same way.
The cut is very smooth, so that's not the problem, I use the 36 teeth blade but also the panther blade but the vibrations
are with both blades.

Now I tried cutting 2 pieces 12mm Okuome plates but it still vibrates.

I made a Video cutting the 12 mm plates, you can hear the vibrations when cutting.
Is this normal for the TS75?

Video cutting with the TS75

Thanks,
Serge

Hi Serge,

I also recently brought a TS75. I have to admit, there is a bit more vibration than I had expected when cutting. However, as you said, the cut is good and clean. I think it has to do with the play in the gears and the electronic speed control.

I,m sure someone will be along soon to tell us both what it is exactly, but I dont think its anything to worry about.

Tim.

Got to ask what is is your cutting on.... I have the 55 and 75 for what you are cutting the 75 is correct. Never had an issue cutting what you cutting. I have heard of some people adjusting there saws without reading the manual or calling Tech and messing them up... not saying you did that.

Without knowing if you are cutting on a hard surface or soft surface...

Would have to say go back to dealer and use their demo unit and your unit... or just call Festool service and see what they can do.

Cheers,
Steve

It seems unlikely that you have two bad blades.

Do you have the little adjusters that limit sideways movement on the rails (what Festool call "setting jaws 1-3" on pages 2 and 18 of the manual) snug?  It could be rattling from side to side.

Steve R,

Are you saying that the vibration is not normal for the TS75?

I have only used mine whilst cutting Particle board/Solid surface composite, at a thickness of 45mm. Some of the cuts were at a 45degree angle, and the material was resting on an 18mm plywood sheet, that was laying on a large workbench. I was also using a specific "Corian" type Festool blade with 72teeth that was brand new.

Roseland,

I assume you mean the "Gimbals" that adjust the friction between the saw and the rail. If so, I always checked that play was at its minimum before doing such a precision cut on Solid surface. As I said, the cut was fine and smooth and accurate.

I was,nt concerned about the vibration, as I thought it was normal for the saw. It,s only after reading Serge,s post that I am beginning to wonder......!!!???

I have the 75 (USA Version), no vibration, real smooth.

Tim,

With any mechanical device that has a rotating blade that had teeth.... depending on many many things it can vibrate. I can my car vibrate by putting chains on the tires to get up a mountain....doesn't make it a problem with the car.

I don't know all the person is doing or encountering.  

After 2  years  of owning at TS75 I can't ever remember it vibrating.  My cuts are usually done on with the correct blade for the type of cut, speed set for the type of wood and I am cutting on a structure that will not give (on location). Never have I had an issue with the TS75.  The TS55 I have tried to cut off bit more than it wanted to chew (so to say) and have had some hard wood be just a bit for it as I pushed it beyond its depth rating... (my fault).

The speed one pushes it depends on the type of wood, cut, blade...etc.

I would suggest the guy tests his along side the dealers demo... that will tell a lot.

Festool service at least in the USA is... well more than good... they are great! One call and any question/concern/issue  I have had has been solved... and I'm very aware of user error.

Cheers,
Steve

Are you concerned about the noise Distinctive?

The video sounds just about normal for a 240v TS75.

The TS 75 should have no real vibration that you would not attribute to the cutting of the material.

I.m not concerned about the noise.

I was,nt concerned about the vibration until I started reading this thread.......!!!  [unsure]

I think I will contact my Festool rep though, just to make sure the saw is running as it should. If the "Vibration" that I,m experiencing is normal, I dont want to look like  [embarassed] !!!!!!

Sould I try another blade first? The blade that came with the saw caused the same kind of vibration as the other blade I fitted. Surely, as someone else mentioned, they cant both be faulty blades..............Can they?

Tim.

 

[windmill man]

I think you may just be getting paranoid about it . All sounds fine.

Just remember , they are out to get you. [big grin] [big grin]

Tim,

Yes I did mean what you call gimbals.

I don't have TS75, just a TS55, but that is smooth.  Mind you I am using the 48 tooth blade.

Cheers WM, I,m beginning to think you are right................ they are out to get me!  [big grin]

Thanks for all the replies

- Surface is a wooden work bench
- Adjustment to the guiderail is checked severall times
- Blades are new and also checked for vibrations.

I compare it to my other circular saws I used before and they didn't shake and vibrate like the TS75.
When I had to cut last week some 100 feet of hardwood thick 2" (intsia bijuga, don't know what it is called in English),
my arm was tired of the vibrations after cutting. I thought it was because of the hard wood but when it still vibrated on soft woods
and 12 mm plates, I wondered if this is normal for the machine.

I have other Festool tools and I'm are very happy working with them all day, but with the TS75 it doesn't feel good.

I was yesterday at the festool dealer but there was no demo machine, I will try a shop in shop dealer next week and take some wood with me to compare to their machine

Is it smooth when it isn't cutting?

With the power cable disconnected, if you turn the blade is there any run out?

Andrew

 

[Serge]

Yes it runs without vibrating when it doesn't cut.

Only thing when I turn the blade by hand 1-2 mm so the motor doesn't turn, I hear the gears make a metall clunk, like there is too much play between the gears without any grease. When I do the same with my dewalt DC300 it makes less metall noise.

I will compare the machine's next week at the dealer and will let you know.

Serge

 

[Roseland]

Were you able to check run out (with the power cable removed!)?  If the blade runs true, and isn't missing any carbide tips I'd guess it's how it should be.  But as I said, my TS55 is smooth.

Andrew

 

[Serge]

I don't know exactly what you mean "with run out with power cable removed" ?

No carbide tips are missing.

Serge

 

[Roseland]

Removing the power cable is just for your safety, and I recommend doing it whenever you work on a tool rather than use it.  It's a nice feature of Festool tools that you can disconnect power right at the tool, and there's no risk that you thought you'd unplugged it, but had actually unplugged a different tool.

To check the run out just turn the blade manually and make sure that the tips all rotate in the same plane.  Ideally you'd do it with a micrometer.  You can get a reasonable idea by holding a straightedge up to the side of the blade as you turn the blade.  If there is any wobble then either the blade is bent or not seated properly for some reason.

I guess the other way to do it would be to make a short cut in a piece of wood and measure the kerf; if it's any wider than the blade tips you have a problem!

Serge

measure from a solidpoint with something very acurate and check to see if the blade is bent etc. loosen the nut sligtly so that the blade can turn on the shaft but not too loose that it can move sideways.
if both meadinds are consistant around the blade then bothe the arbor of the saw and the blade are spinning true
