My DW939 quit. I smelled some smoke. Do you think it is repairable? How do I test the components?

Question: DW 939 Slipping Saw Blade

Gordon Gould

I can't keep the saw blade from slipping on the arbor shaft. The blade is not keyed as the lock washer is. I've tightened it as far as it will go and the blade still slips. How do I fix it?

Take the black end cap (pn 39) off so you can see the end of the armature shaft. Turn the blade by hand and see if that small shaft is turning. Mine stripped the gear on the other end of the armature shaft and the blade is actually free-wheeling. I could be wrong but I bet this is your problem.

How do you remove the retaining ring?

Hi k,

I am guessing your are referring to item #34 on the parts diagram. It is a spring type retaining ring. If you look at the edge of it closely you will see that it is wound like a spring with a couple of layers. Take a small screwdriver and separate the layers apart. then slide the screwdriver, in between the layers, around the retainer. This will lift the retainer up so you can pull it off of the hub.

Good luck with your repair!

Question: Dewallt Cordless Circular Saws

dbeier@nctc.net

hi. i am looking to buy a dewalt 18v cordless circular saw, mainly this brand because it is good and also because i already have the batteries and charger. can someone tell me the difference between the dc 390 and the dw 939? thanks...

Hey,
The DW939 is a totally redesigned saw with a lot better quality. all the internal parts are different from the dc390...but along comes with that is it costs more to repair..!
Hope this has been helpful..

I called makita and they said buy the dc 390, because that the dw 939 was discontinued. But you got me going now because the dw 939 sounds like a better tool. At ewarehousedirect .com they have both tools reconditioned, the dc390 for 39.99 and the dw939 for 89.95. I thought the dw939 cost more because it was older and availability was less, but maybe it cost more because be cause its better. What do you think?

Thanks dave...

My saw has trouble even cutting through piece of plywood. tried a new blade, new battery, and yes it was charged. Could it be the brushes, and if so how would i know they were worn out. I pulled them out and looked at them but they dont look all that worn.
