Festool CT Midi
« on: November 29, 2022, 03:52 PM »
Hi. I got an older CT Midi, the one with auto/max and turtle/hare switch and not much else.

Worked perfectly well for me on my own home projects for the three years i have owned it. Not doing this for money, just for myself. previous life the vacuum was in a wood shop.

Anyway, last time it was 100% was before I was sanding when plastering. The hepa filter was clogged and i don't think the vacuum liked that very much.
it has a new hepa filter, a new bag and has just been used to vacuum up after removing a fireplace right now. But it has been wonkey for a while.

So now it starts, runs for a minute to five minutes, then dies. I have to take it out, wait a few seconds and plug it in. So it works. Just a bit like when I am running, I really don't do hills and other stuff that is really draining.

It seems to me to be the turbine. How do I know if it just need new brushes and how do I do that, or if the turbine should be replaced? Or could it be something else that make a new turbine or new brushes a waste of money?

Any idea what to do? I really like the vacuum, so I'd prefer to keep it for the next decade or so.

I don't think that the brushes are the issue. In my experience, if the brushes are somehow jammed, the motor simply will not work. Also, the brushes  will automatically disconnect if they get too worn. I don't really have anything else to suggest, though.

Ok, good to know. Because then I can scratch that off the table. I'll go over the connectors and see if anything is loose. if that isn't the case, the motor might just be on its last leg.

There was an issue with some of the smaller CT's (can't remember if it was the mini) where the power cable would break internally at the point of the cable clamp just inside the the unit, if you wiggle the power cable near the entry does this do anything?
