I dont know how old the tool is but when I worked on them it was notorious for exploding the commutator and damaging the brush holders, hopefully yours didn't do that. You have voltage at both brush holder then I would remove the brushes (UNPLUG TOOL FIRST) making sure they are not sticking in the tubes and while they are out rotate the tool by hand and look for any noticable difference in the commutator bars. Check all the connections from the field to make sure the circuit is complete like it sounds that you have done and if so that just leaves the two items I mentioned. Let me know if I can help further.

    Instead of checking voltage check for continuity thru each leg of the field and from the switch to the wires that feed the field. Other than that are the brushes stuck and if not you have me stumped.

12" Milwaukee. Why does it lose power after it has been run for awhile?


Assuming there isn't some other mechanical problem or the saw isn't being overloaded, most circular saws have motor brushes that can wear out after extended use. These brushes are usually replaceable. When the brushes are worn, they will not deliver sufficient power from the motor stator to the armature (the part that rotates).

Here is a link to a parts supplier. Find your model number and look for brushes.

The model number is Milwaukee 26 30?20 it needs a new switch it up

Lay the saw on its side with the screw in the handle facing up and battery removed... remove screw along the two half's of the saw.... you will see a seam where the left and right side meet... once screws are removed ( make sure you remember what screw goes where, there may be different sizes) lightly pry apart incase you missed a hidden screw, I'd so remove it... disconnect old broken switch and install new one... may have to order the part in

I have a Milwaukee circular saw model 6365. It still cuts fine, but it squeals loudly (like a little girl) when running. Sorry, couldn't help myself. Seems like the motor bearing(s) need lubrication. ...

You can try to lube the bushings, but they will always start to squeal again. I have tried just about everything, 2 cycle oil works good, wd-40 is a little thin, blaster works ok for a while, reg 3m oil forget it, motor oil, no, white grease, hard to get in there, axle grease, yes, but you have to take the bushings out. The oils, you don't have to take the saw apart. Hope this helps.

I need to replace cut electric chord on saw 6390-20

I would go to and download a breakdown for this tool. But all you have to do is remove the screws holding the handle assembly to expose the switch area and cord. I think they are a T-20 Torx, after removing the half make a note of the wiring before removing the old cord. trim the leads using the old cord as a guide and reinstall. what you want to do is when you reinstall the screws back them until you feel the first thread so you don't rethread it. These are thread forming screws and after a time they will strip out the threads. It is really quite simple

I need a wiring diagram for a milwaukee heav duty circular saw

It is probably something like a 6365 and on all the Milwaukee products they have a switch wiring diagram but nothing for the switch. I would recommend going to a local repair center with the switch and match it up with a new one probably less than 15.00 If you give me your location with zip code I can direct you to the closest one. Let me know
