It seems I have burnt the armature on my TS55. I like to repair things myself, and normally manage well, but I do not manage to pull the TS55 apart:
Is there a trick, besides the 4 screws that hold the motor housing to the gear housing? I can get a gap of about 10 mm, but it stops there.
 
If you go to your countries festool site, there should be a link to a site with parts drawings (exploded views) (ekat) (it's usually in the service and support section).

I have no experience with the Q version of the ts55, because the EBQ is the only version available here. But the EBQ version has a built in thermal protection. This shuts down the saw, and it will not turn on for a while; but if you wait long enough it wil work again.
 
Oh, it's burnt alright.
It starts, but runs at low speed and no power at all, and smells like electrical barbeque. I am pretty sure it is the armature, but want to take it apart to check if it might be the electronics before I order parts, and of course need to be sure I manage to take it apart at all. It rotates with no problem by hand, so the bearings are probably OK.
 
Thanks, but: "Access to the specified resource () has been forbidden."

Thanks.
I have seen it before, and it is a bit small - should wish it was possible to zoom in. I cannot see anything that holds it together, I guess I have to try again.
 
You should be able to zoom the diagram.  The controls are at the upper left of the diagram.  Click on the + sign repeatedly if necessary.

Good Luck!

Hi

Could it be as easy as that the brushes are worn out?

No, I have checked the brushes, they are just fine. It starts and runs, but slowly, and smells like a burnt motor smells, not like if the brushes are worn.
It looks like I will have to dismount more parts to take it apart, a bit strange, but I will try again.
 
My guess is that you've lost the bearings and the rotor is rubbing on the stator. If they heated up enough, the bearing pockets are no longer where they belong. This is not something that even I would attempt to repair myself.

You might very well be right. I am not sure what to do. The Festool guys here in Norway are so  [eek] expensive. A repair could well end up being as expensive as buying a new from UK.
 
Not to sure what has happened to your saw, but the thermal overload system works like this;
If the motor over heats the electronics kick in and run the motor at slow speed to keep air flow moving over the motor thus cooling it. 
If you shop the motor before the air has cooled it it will become a heat sink and melt down.
Normally if your Festool tool slows down due to thermal over load keep running the tool until it speeds up again.
I know this doesn't help you take the tool apart, but I have found Festool tools the easiest tools to work on and repair. (but never worked on the TS saws) [unsure]

I was ripping some thick pine (~50 mm) and the saw was bogging down during ripping. No low speed protection mode (like I am familiar with from the Rotex), it just started smelling and lost power, I did try to cool it like you describe, but it did not help.
The bearings seem to be OK, but of course it is possible that the bearing fixtures have been melted and damaged.

Edit: I will just try to pull it apart, and if it works I repair it, if it is damaged, I buy a new RQ or REBQ instead: The price of the anchor, a new saw blade, cord, Systainer and so on, is more than half the cost of a new machine. I do not want to put any more than that into an old machine that already has a problem, when the R has a lot of improvements.
