OF2200 repair advice.

[eightball]

I have an OF2200 that is tripping 20A circuits and on occasion seizing up. 

Debating on whether to send it in for service or to simply purchase a new spindle which seemed to be about ~$300.

My concern is if I send it in and it does indeed need a new spindle, I'm out a not insignificant shipping fee there and back.  If I just bite the bullet and buy the spindle I'm only paying shipping one way.

Am I nuts? Anyone have experience with similar issues?

Out of the parts in a motor and controller that could fail, I would suspect the armature to be the least likely culprit. Usually it's windings in the field that might fail due to the wire insulation breakdown, although I'd suspect the control board in this case myself.

The OF2200 is a beast and worth repairing, I'd send it in myself in lieu of any more concrete knowledge of what the issue actually is, unless you know someone you could borrow their controller from the test.

You're nuts if you don't try new brushes, first

Purchasing and installing a new spindle is a c r a p shoot...I'd echo tsmi243 thoughts and replace the brushes first...a $20 ticket. If that doesn't work then it's probably the control board, but at that juncture, I'd just send it back to Festool and let them do their thing.

thanks for the advice.

How complicated is replacing the brushes? (although, given above I'm leaning towards sending it in)

The nice thing about Festool is that they're designed to be serviced, so they generally come apart fairly easily with screw removal, unlike some commodity-level tools that are glued together and unserviceable.

I started getting motion sick watching this, but there's at least one set of videos on Youtube on how to get to them and replace them.

[member=27165]eightball[/member] if you were considering replacing the spindle and armature yourself, you should be able to replace the brushes.  [big grin]

This reminds me of something I heard a long time ago.  Knowledge is knowing a tomato is a fruit.  Wisdom is knowing not to add a tomato to fruit salad.

send it in, theyll go through it and make it like new when ya get it back and ya get a limited warranty on the repair....

The thing with brushes is if they're ran too low they can damage the commutator (part of the armature the brushes ride on).
This definitely could be brushes; when they're low they don't always make good contact.
Ii personally deal with my stuff as much as I can.
If you replace the brushes and it's still doing it you could still send it in.

Or, pull it apart first and check the brushes.
Post pictures if you're not sure.
