I bought a used 16 inch , model 1680, Dremel scroll saw on Craig’s List last summer. I checked it out before buying it and it seemed in good condition. It ran very smoothly and didn’t seem to have any issues. I haven’t used it since then, but I started a project recently where I would be using it. I’ve used it maybe 10 minutes, and today I was using it and it was working fine. I turned it off to move it and when I turned it on again it would not turn on. I’m not getting anything. No fan, no noise , just nothing. I don’t have I light bulb installed, I guess I could get one to see if anything is getting juice. My question is, is there some kinda of re-set button that I’m missing that could fix this problem? I checked the bushings and they seemed good. I lubricated it. I’m stumped. Don’t want to buy another one having barley used this one. Any suggestions? Thanks

Remove brush caps and check condition of brushes.

If the surfaces of the brushes that contact the commutator are rough,pitted,or less than 1/8”, replace them.

The brushes will wear unevenly usually. If one is bad, replace both. If you do replace the brushes, run the saw with no load (freely) for 5 minutes. This seats the brushes and will provide longer life for them.

Assume you already checked the outlet for power. Did you leave it plugged in when you moved it ? Is it the same outlet ?

Maybe the cord has an intermittment open in it and when you moved the saw , the cord moved and lost conduction.

Blow out the motor with compressed air.

Check wiring at the motor

Check Plug and cord for opens with a voltmeter. If everything else checks out, try a new plug.

If that doesn’t do it. Its could be the commutator in the motor is bad.

Thanks Ron. I got it to work yesterday. I took an air compressor and blew out the switch area. I was getting power to the switch. I plugged the connections, but that didn’t work until I blew the dust out. I’ll remember you advice in the future. I’m new to using a scroll saw and hopefully in the future your good advice will come in handy. Thanks.

No problem.

I have heard of that before. Dust or critters getting into the switch box and shorting out the unit. Glad you found the problem and was an easy fix.

Have your say...
