What to do if my Jet Sander belt has a short life?

  To extend the belt life of your Jet Sander, avoid applying excessive pressure while grinding; let the belt do the cutting, as excessive pressure dulls the grit. Use all surface areas of the abrasive cloth instead of working on only one side of the belt or one area of the disc. Also, ensure you are using the correct abrasive material and grit size for your workpieces; consult your abrasives supplier for recommendations.

How to troubleshoot a Jet Sander when the motor will not run?
- K
  Kyle ReynoldsAug 11, 2025
  If the Jet Sander motor won't run, there are several possible reasons. First, the voltage might be too low, so check the power supply. A blown fuse or tripped circuit breaker could also be the culprit; determine why it happened and replace the fuse or reset the breaker. Ensure that the branch isn't shut down for service. Inspect all wire connections for any looseness. If none of these solutions work, the motor or the switch might be defective and need replacement.

  If your Jet Sander motor stalls easily, it could be due to low voltage. Check the voltage at the motor and correct if necessary. For three-phase motors, a blown fuse could be the cause, so replace the blown fuse. Improper wiring can also lead to stalling, so check all connections to ensure they are properly connected.

How to fix poor tracking on a Jet Sander?
- D

  If your Jet Sander has poor tracking, consider these potential causes: 1. Tracking may be out of adjustment, so adjust the belt tracking. 2. Too much belt tension: loosen the tension until the belt is just taut. 3. Not enough belt tension: tighten the tension until the belt is more taut. 4. The belt may be jointed improperly, so check the belt for an irregular seam or shape. 5. There may be a lack of crown on the drive roller, so check for a slight crown and replace the roller if the crown has worn away. 6. Worn bearings can also cause tracking issues, so check all the bearings for excessive heat or loose shafts and replace if necessary.
