Hi everyone,
I've just got hold of a used Jet 1220vs lathe, and hope you can help me get to the bottom of a fault.
It has a speed dial from 1 to 5. When I turn it on at 1 it runs slowly, but inconsistently...runs for a few seconds then slows a bit, then speeds up. At 2, it runs slower and sometimes stops, at 3, much the same as 2. 4 is faster, 5 full speed.
The dial is also sensitive to the touch...gently move it the smallest amount and it sometimes make it slow almost to a halt.
I've tried moving the belts to different points but exactly the same problem. Have tried blowing the motor out with air but no help.
Anyone experienced something similar? Am hoping it's a simple wiring fault or something but am clueless when it come to electrical stuff!
Any thoughts welcomed!
Thanks,
Rick

Sounds like the potentiometer has either got full of dust or needs replacing

Yes I agree. A suitable replacement should be available from Jet. But check with them before buying as it may be something else.
