Neighbor asked if I would do him a favor and look at his Milwakee sawzall. Said his pant leg got tied up in it and it hasn't worked since. I had to take it a part to get the denim pieces out of the blade end but it still would not work. Dug into it further an found that the armature had wrapped up some denim thread, enough to keep the brushes from making contact. Pulled the thread out and it works just fine again. First time I ever seen a pair of jeans take out a power tool.

Looks like this saw has seen some real use/work. I have one and it is a great tool.
