      If your Grizzly Sander vibrates or operates noisily, check the following: * Inspect and replace any damaged bolts/nuts, and re-tighten them with thread locking fluid if the motor or any component is loose. * Fix or replace the fan cover and replace the fan if the motor fan is rubbing on the fan cover. * Test the motor bearings by rotating the shaft; bearing replacement is required if there's rotational grinding or a loose shaft. * Inspect and repair or replace the gearbox if it's damaged.

    Why does my Grizzly G1071 Sander leave deep grooves?
    • M
      Melanie SalazarAug 9, 2025
      If your Grizzly Sander is leaving deep sanding grooves or scars on the workpiece, it could be due to several reasons. First, the sanding sleeve might be too coarse for the desired finish, so try using a finer grit sanding sleeve. Second, you might be sanding across the grain; make sure to sand with the grain. Finally, you might be applying too much sanding force; reduce the pressure on the workpiece while sanding.

    What to do if sanding surfaces clog quickly on my Grizzly G1071 Sander?
    • S
      Shawn PowellAug 15, 2025
      If sanding surfaces clog quickly or burn when using your Grizzly Sander, it could be due to applying too much pressure against the sleeve. Try reducing the pressure on the workpiece while sanding. Alternatively, if you are sanding softwood, consider using a different type of wood. If that's not an option, accept the characteristics of the softwood and plan on cleaning or replacing the sanding sleeves frequently.

    Why do grains rub off the sanding sleeve of my Grizzly G1071?
    • J
      Jeremy MeyerAug 19, 2025
      If grains rub off the sanding sleeve of your Grizzly Sander, it could be because the sanding sleeve has been stored in an incorrect environment. Store sanding sleeves away from extreme temperatures and humidity. It may also be happening because the sanding sleeve has been folded or smashed. Store sanding sleeves separately and not folded or flat.
