Fuse keeps blowing

[reg]

I have 5 of these saws in my shop and all are running except one. Today the fuse blew. I replaced it and it blew again. Any suggestions?

Say reg, are your replacement fuses a #3 AG fast acting 1 1/4 long x 1/4'' diameter fuse? That's what the type 2 dewalt scroll saw calls for!
I'm not sure on the type for the type 1 scroll saw.
But you might need check that you're using the right replacement fuses.
If for some reason your saw is drawing more then 3 amps it will blow the overload protection fuse.

Next you could check the brushes in the motor and see if you don't have one causing it to over load the motor. If it's blowing the fuse while running!
If it's blowing the fuse before the power is turned on you might have a power wire that's bare, causing it to short out. Or a loose connection causing it to pull more then 3 amps.
