Possessed Dewalt 788

Hey guys, I am at a loss, I have had my saw for about a year and a half. Well yesterday I was cutting and all of a sudden my saw started changing speed on its own.. It also seemed to start vibrating alot more than normal. I shut it off and on a couple of times and turned the speed up and down, and then it stopped and started working again. It has done this one other time, about a month ago. Anyone else have this happen?

My speed would do that occasionally. Blow the dust out of the dial and try and protect that and your on/off switch from as much dust as possible. If you use a foot control blow it out regularly as well. Can't ofer any help with the vibration. I have yet to open my 788 and won't until I have to. Let a sleeping dog sleep.

My last one did that just before it croaked. Luckily it was still under warranty. Hope you can figure out the problem.

I've had my 788 for 3 years now & not any real problems-nock-on-wood-. I use a lot of spiral blades & they are my only problem---- (getting them fastened without breaking them). The twist is always the wrong way. I have tried twisting the ends straight, but, did you ever try holding those tiny little blades with a pliers? I'm not on a schedule, so I manage OK. It's just a "good ole yeller" saw.

I have used it for the past couple of days without incident, I have my fingers crossed, I clean it about once an hour. ubgoofy I had the same problem with the spirals, I use them alot as well, I figured out that if you secure it to the bottom first, while leaving the top of the blade loose, I almost never have an issue anymore.

With my Dewalt using spiral blades I would hold the blade loosley and tighten the bottom screw. The blade woild turn a bit as I tightened then clamp down ok. The top screw would then tighten without bending or kinking the blade.

Welll, I called the repair center today, was told that they had not even looked at my saw ... I said heck with it and ordered an EX-21...... will be here monday... I really loved my dewalt (when it worked) I hope the ex-21 will cut just as good, but actually hold up to my use...

G'day Prale,
I have both the Ex21 and Dewalt. The Dewalt had problems which made me order an Ex. I have repaired the Dewalt and it now sits ready for action if the Ex gives up the ghost.

I had my DeWalt for a little over a year when it would speed up by itself. It was spooky. lol It did this a few times, and then it stopped working all together. I took it into the repair shop. Seems the magnets in the motor had disconnected. I am now on my second motor. New motor is running like a top.
