    How to fix excessive vibration on Powermatic 3520C Lathe?
    • M
      Melissa RobinsonJul 27, 2025
      If your Powermatic Lathe experiences excessive vibration, several factors could be the cause. The workpiece might be warped, out of round, have a major flaw, or was improperly prepared for turning; correct this by planing or sawing the workpiece, or discard it and use a new one. Other potential causes include worn spindle bearings (replace them), a worn drive belt (replace it), a loose motor mount lock handle (tighten it), or the lathe being on an uneven surface (adjust the levelers).

    What to do if tailstock moves when applying pressure on Powermatic 3520C?

      Jessica TownsendJul 31, 2025
      If the tailstock moves when applying pressure on your Powermatic Lathe, ensure the locking handle is tightened. Also, the cam lock nut may need adjusting, so tighten it. If the lathe bed and tailstock mating surfaces are greasy or oily, remove the tailstock and clean the surfaces with a cleaner/degreaser and re-apply a light coat of oil to the bed surface.

    Why does my Powermatic 3520C motor fail to develop full power?
    • T
      Thomas WeberAug 5, 2025
      If the Powermatic Lathe motor fails to develop full power, it might be due to a few reasons. The power line could be overloaded, so correct any overload conditions. Another cause could be undersized wires in the power supply system, in which case you should increase the supply wire size. It could also be due to a worn motor, so consider replacing it. If the inverter is faulty, contact Powermatic Technical Service.

    What to do if Powermatic 3520C motor or spindle stalls?
    • W
      Walter HooperAug 9, 2025
      If the motor or spindle stalls or won't start on your Powermatic Lathe, consider these possible causes. You might be taking an excessive cut, so reduce the depth of cut. The belt adjustment could be improper, or the belt could be worn or broken, so adjust or replace the belt as needed. Also, check for improper cooling of the motor by blowing out sawdust from the motor housing fan. Worn spindle bearings or a worn motor can also cause these issues, so replace the bearings or motor as necessary.

    Why does my Powermatic 3520C Lathe run at one speed only?
    • D
      Dawn DavisAug 13, 2025
      If your Powermatic Lathe runs at only one speed, the potentiometer might be faulty, so replace it. It's also possible that the electronic AC inverter is not programmed properly, is defective, or has loose wiring. Contact Powermatic Technical Service for assistance in identifying the problem.

    What causes tools to grab or dig in on a Powermatic Lathe?
    • B
      Billy CollinsAug 18, 2025
      If tools tend to grab or dig in while using your Powermatic Lathe, it could be due to several reasons. The tools might be dull, so keep them sharp. The tool support might be set too low, so reposition the tool support height. Also, check if the tool support is set too far from the workpiece and reposition it closer. Finally, ensure you are using the correct tool for the operation.

    Why does the headstock move when applying pressure with the tailstock on my Powermatic 3520C Lathe?
    • C
      Cynthia OnealAug 21, 2025
      If the headstock moves when applying pressure with the tailstock on your Powermatic Lathe, it could be because the headstock is not locked to the bed, so tighten the headstock locking handle. It could also be due to excessive pressure being applied by the tailstock (more than 500 lbs of force). Slide the headstock to the left end, then apply only sufficient force with the tailstock to hold the workpiece securely in place.
