Removing Fan from ETS EC 150/3 EQ (500 071)

[friedchicken]

Hey;
I just picked up at a pawn shop an extremely well worn ETS EC 150/3 EQ that's been through the ringer.  There is a lot of hard built on crap inside the unit I'd like to clean out.  I've already taken the case apart and washed that extensively with soap and water.

The insides and electronics I want to blow out with compressed air and maybe some cleaning agent.  I noticed some rust on the stator, but I don't think that's a problem and I'm hesitant to put any WD40 on there.





Anyway, where I'm stuck: I can't figure out how to get the fan unit off, and I'm hesitant to remove the screws b/c I believe the positioning plays a role in balancing.



It would be a lot easier to remove it to clear our whatever might be in the motor with compressed air, and then soak and clean the fan assembly.

I consulted the parts diagram but still couldn't decipher it:



If someone in repairs has any tips, tricks, or advice, it would be much appreciated!

I've gone ahead and put everything back together.

I believe that fan is press fit to the armature shaft, and I wasn't inclined to go further.  Cleaning it up improved vibrations significantly.

The tools is now together and the next step is: what parts/accessories do I need for this

I additionally cleaned the case bits in soapy water while I had it apart; almost ran it through the dishwasher but it was empty so I didn't.  Lubricated the bearing receptacle with some wheel bearing grease (the stuff in there seemed a bit thick), picked out all the stuck on bits like I said, and blew out the dust from the inside.

Here are the results:

My question, does Festool offer a service like this?  Clean/refurbish?

Nice work!

Yes, to a certain extent Festool does this.  When you send in a tool for service, they will repair/replace any wear parts in addition to any broken parts to return it to "nearly new" status.  I don't know how much, if any, cleaning is a part of that for the tool body itself.

Once you get the quote from Festool, you have three options:
1) Pay the fee and the work will be done
2) Decline the fee and request the tool returned; the tool is returned disassembled
3) Decline the fee and abandon the tool altogether; the tool is refurbished and sold on the Recon site and/or scrapped for parts, depending on an internal assessment (most likely).

That's great but what if you have a tool that's otherwise functioning perfectly fine (as is the case with this sander)?
I suspeted Festool might do that: return the product in like-new condition.  Good lord, it really is a company for professionals and I am decidedly not a professional.

You'd have to call and ask them.  My guess is that they'd still replace any wear parts that are out of spec and charge time for disassembly and cleaning.
