  Luis BrownSep 13, 2025
  If the workpiece is thrown from the table of your Grizzly Power Tool, it could be due to: * The workpiece not being secure. Properly clamp the workpiece on the table or in a vise. * The tool or bit being too large for the feed speed. Use a smaller tool or bit or decrease the feed speed.

What to do if Grizzly T33959 chuck falls out?
- B
  Bethany CraigSep 7, 2025
  If the chuck and arbor fall out or are loose in the spindle of your Grizzly Power Tool, it might be because: * There is debris on the chuck, arbor, or in the spindle taper. Remove the chuck and arbor, clean all these parts, and then reinstall. Deburr mating surfaces if necessary. * There is excessive feed pressure. Decrease the feed pressure and allow chips to clear.

Why is the LED not illuminating on my Grizzly T33959 Power Tool?
- A
  Anna HernandezSep 6, 2025
  If the LED on your Grizzly Power Tool is not illuminating, it could be due to: * The lens being covered with dust. Clean the lens. * Broken, disconnected, or corroded wiring. Fix the broken wires or disconnected/corroded connections. * A damaged or faulty LED. Replace the LED. * A damaged or faulty spindle speed digital readout circuit board (T33959/T33960 only). Replace the spindle speed digital readout. * A damaged or faulty LED driver (T33961 only). Replace the driver. * A faulty LED switch. Replace the LED switch.

Why are my Grizzly T33959 Power Tool cutters breaking?
- T
  Taylor MurrayAug 21, 2025
  There are several reasons why your Grizzly Power Tool cutters might be breaking: * The spindle speed or feed rate may be too fast, so reduce them. * You might be taking too big of a cut at one time, so decrease feed pressure and allow chips to clear. * The cutting tool may be too small, so use a larger cutting tool and slower feed rate. * The cutting tool may be getting too hot, so use coolant or oil or reduce cutting speed. * You may be using the wrong cutting technique, tool, or machine for the job, so use the right ones. * The spindle may be extended too far down, so fully retract the spindle and raise the table to increase rigidity.
