What to do if my Wen 3970 Saw machine stalls?

  Justin WoodAug 22, 2025
  If your machine stalls or seems underpowered, it might be due to using the wrong blade for the material. Try using a blade that's better suited for the type of material you're cutting. Also, inspect the V-belt for wear or looseness, and replace it if needed. Finally, check if the pulley is loose; if so, realign the pulleys and tighten the set screws.

Why is my Wen 3970 Saw cutting inaccurately?
- L
  lloydbrianAug 26, 2025
  Inaccurate cuts can occur due to several reasons. You might be applying too much cutting pressure (incorrect feed rate), so try decreasing the feed rate. The blade tooth count could be incorrect for the material; consider using a more suitable blade. Also, check the sliding blade guides to ensure they are adjusted as close to the workpiece as possible. Incorrect cutting speeds, a workpiece not securely clamped, poor blade tension can also cause the problem. Make sure to re-clamp the workpiece properly, check blade tension and adjust the cutting speed.

  Excessive vibration or noise can be caused by several factors. Check if the V-belt is hitting the belt cover and ensure the cover is properly installed. Inspect the V-belt for wear or looseness, replacing it if necessary. Also, verify that the pulley is not loose; if it is, realign the pulleys and tighten the set screws.

What to do if blade teeth are ripping from my Wen Saw?
- D
  Dylan LeonardAug 30, 2025
  If the teeth are ripping from the blade, it might be because the feed rate is too high, the blade speed is too slow, or the blade is too coarse for the workpiece. Try decreasing the feed rate, adjusting the blade speed, or replacing the blade with a more appropriate one. Also, ensure the workpiece is securely clamped, using a jig if necessary. If the blade teeth gullets are loading up with chips, switch to a coarser-tooth blade.

  If your Wen Saw machine stalls or seems underpowered, it could be due to several factors. Ensure you're using the correct blade for the workpiece material, especially if you're cutting metal. Also, the feed rate might be too fast for the task at hand, or the V-belt might be slipping. To fix this, use a blade with the correct properties for your type of cutting, decrease the feed rate, and replace or re-tension the V-belt.

What to do if teeth are ripping from the blade of my Wen Saw?
- D
  Dr. Diana MillerSep 6, 2025
  If teeth are ripping from the blade of your Wen Saw, it could be because the feed pressure is too heavy, the blade speed is too slow, or the blade TPI is too coarse for the workpiece. It might also be that the workpiece is vibrating in the vise, or the blade gullets are loading up with chips. Try decreasing the feed pressure, selecting the proper blade, re-clamping the workpiece securely, and using a coarser-tooth blade.

How to fix a Wen 3970 Saw blade that protrudes from the guide?
- M
  Marvin HamiltonSep 9, 2025
  If the blade on your Wen Saw tends to protrude from the guide, it could be due to excessive blade tension or incorrect eccentric blade guide adjustment. Another cause might be the blade slipping on the pulleys because of oil or grease. Check the blade tension and eccentric blade guide adjustment. Never use any lubricant or coolant for cutting operations; specialized personnel should check and replace the pulleys if necessary.
