- What else can I say, these motors simply don't last. A few years is all your getting out if these saws.
best to avoid the adaptor altogether, as that is what's causing most of thembti burn out.

I am a subscriber of Matthias Wandel for the last 12 years. Have seen every single video posted by him and now it is your turn 😂 love the videos, the speed of your content and how ridiculously easy you make it look.
I love collecting and using and being around tools and your channel is like finding gold.
With your help Dean my mate and I replaced the motor on his yesterday, took about 20 minutes. He got his new motor for £240. Thanks man.
Thanks, I'm happy to hear the video helped. 👍
Where abouts did you get a motor for £240 please?
Where did you order it from?
£280 the cheapest I can find on Ebay?
Thanks for the video, not much out there about this saw video wise.
I burnt mine out connecting to the mains, and blew my fuse box at home.
Mine just blew on batteries. Hardly ever used the adapter because I have a different, lighter, corded saw. Thanks for the video. Watching you use the double sided tape for decals blew my mind. So simple yet genius
My corded Bosch was on the pricey side but keep on going I keep on abusing it, remain strong after 15 years. Even cut 6" tree branches and had it in outdoor the last 3 years. No service, maintenance or parts required while my foldable mobile miter saw stand falling apart. I'm having second thoughts relative to those cordless miter saws now.
Sounds like Dewalt is taking a number out of Milwaukee’s serviceable parts book.
Great video, my saw detonated on me today for the 2nd time, ive forked out for the newer version of this that runs on a single battery as i need a mitre saw asap but im fed up with this keep happening, hopefully the newer one will be better🤞
Good job 👍 but that’s a very expensive one will you keep the rest of that motor to fix other ones to save some money?
Hit the like button 👍 before you leave.
Working the best ever since dean. Cheers 👍🏽
Great video,thanks Dean👍.
Interesting the drive belt looks like a 1:1 ratio. A bigger drive spindle / gear would take some load off the motor.
It's not the load on the motor that burns it out. There is an adaptor to run it of the mains instead of the batteries. It's the adaptor that cooks the motor every time
@@deandohertygreaser are they taking 54+54 and getting a 110 out of it? Because that only sounds like 108
@@stauker.1960108, 110, 120, etc. Its the same thing. 108v is the nominal or actual voltage for 110-120v dc
Was waiting for one of these to show up ,interesting !!
Hey there, nice video! I've got the 12 inch dewalt dcs781. No light, no action. What does a guy do to start trouble shooting? I've had it apart... Looks like a new saw to me. Subscribed
Where did you get the new motor from?
Thank you so much for this!
Wish id have watched this before replacing mine, used with adapter got 2 cuts out of it & bang fuse popped, new motor needed again. To me they need to resolve this and @ £250 were the fudge are my stickers
Hi dean just came across your channel great content! Would you recommend a makita xgt mitre saw over dewalt?
Mines flashing the led light when you try turn it on and no power when you pull the trigger .any thoughts ?
I liked the video mate, I have mostly all Dewalt tools and had this saw which died on me. This saw is a complete scam and refuse to fix it as the chances of it failing again are almost guaranteed. Its a shame, was a decent saw.
It's crazy how many people this has been happening to. You'd think a recall would be in order, or whenever someone blows a motor on warranty, an upgrade happens making it pure cordless.
I bought a duel power miter saw because I was scared to go full cordless, thinking a miter saw needs lots of power, but it really doesn't. I've had it a year and never once used the adapter. A battery will last all day no problem
Would a dws779 motor swap and xps light module work as a permanent conversion to corded?
where or how can i buy the motor
Matias Good day My name is Stanislav I'm from Ukraine I bought my same saw in America and I also have problems with the engine Give me a link where I can order this engine to replace it with a broken saw, thank you very much
Hey dean. Need to replace the motor on my dhs780 after using the adapter numerous times. But not sure whether to just get the draper expert double bevel 230v. Any thoughts from yourself or anyone really. Thanks muchly.
No comparison between the Dewalt and the Draper. The draper is a very basic miter saw. if your looking for a cheaper saw, look at evolution or metabo. Or if you wanted to, you could convert the 54v into a 240v motor instead. Costs just a little bit more than the 54v motor.
Hi there m8. Wow thanks for the reply I really appreciate it. Is a 240 conversion possible is it. That would be something I would definitely be interested in doing. The battery motor swap looks easy enough to do. but I wouldn’t even know where to start with the conversion. sure you get this all the time but could you give me some pointers or do you know of any videos out there that would help me. Thanks again.
My mates bit the dust 2 weeks ago and he only ran it with batteries.
Can a motor to be fixed
You sure could but would it be cost effective vs new? It would for larger motors, used to work for a company that send out their 1,000 HP motors for repairs.
Who in their right mind would buy such a thing in cordless? The twin batteries alone are what, 300eur? People are idiots.
So you gota buy the whole motor unit!
When all that was blown was a few pennies worth of a fet. Appreciate it’s all potted and could be repaired with time and patience.
But why can’t you just buy the controller on its own? They looked to be mostly hard wired so appreciate it’s not an easy job. But still.
And you dislike Milwaukee for grouping parts together?
You don’t have a agenda do you Dean?
I do enjoy your content and respect your work but gotta be fair!
You Are 100 percent right, it's a joke. The controller that fails could easily be sold seperatly. It's not even hard wired in, it has cable connectors. It would be easier to replace than the whole motor.
It's a black mark agents dewalt.
The reason I don't like milwaukee is they do this with all their tools now.
I think that is pretty crap, that they blow that easy, guys are investing that amount of money
agree totally. they should at least be selling the control board separately from the motor.
