Purchased a supposedly nearly-new Dewalt 788 within the past year. We haven't used it much at all yet. Noticing that the motor is bogging down when blade tension is increased. What do I need to know to overcome this motor bog down issue?



The above link is to a video of the saw bogging down when using tension control.

Is that happening while you are cutting or it bogs down as soon as you increase the blade tension?
Increasing the tension should not cause the motor to bog down.
The speed control on the Dewalt 788 is known to be problematic, sawdust can creep in it and cause it to fail, maybe that's the problem with yours, try blowing some compressed air in there and see if it changes anything.

Try scroll saw .com site,there are many members there who own that model of scroll saw ,maybe they'll know what's going on with yours:

welcome to the forum. im thinking a video of exactly what youre experiencing may be helpful. my old 788 would have a change of sound with different blade tensions, but never had a problem with speed slowing down.
im thinking a video of what your experiencing may help.

only thingmi could think of causing what im picturing is a bearing problem, but id like to see and hear a video.
