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.

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

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.PERK

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.Smitty

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.Regards

SQIf you can't fix it with sawdust and glue, it's not worth fixing.

Reply to Question about tilting head sawsby RolfI have both types of saw A tilting table Hawk g426 and an Older Excalibur with a tilting head. Unlike Carole for bevel cuts I prefer the tilting head I do larger projects and it is easier for me.
Regarding compound cuts they are cut at 90 degrees.
If I were in the market for a new...-

Reply to Question about tilting head sawsby handibunnyIf you have a good saw, and can set the table accurately, you should be good to go. Give a holler if you need help. ๐
Randy, I swapped out the clamps on the Jet for the Pegas clamps as soon as they became available. I found the Jet clamps just too fidgety for my taste.-
