Troubleshooting
Symptom | Possible Causes |
Motor does not start | 1. Check that the cord is properly plugged into an outlet. |
| 2. Make sure the outlet has power. Check the circuit breaker or try another outlet. |
| 3. If used with a Festool dust extractor, make sure the selector switch is pointing to |
| "Auto". The auxiliary outlet on the dust extractor has power only when the |
| selector is at Auto. |
| 4. Inspect the power cord (including extension cords) for damage or missing |
| prongs. |
| 5. The motor brushes may have worn and need replacement. |

| The electronic controller in the motor controls the motor speed by turning it On |

The saw makes wavy cuts | ► Make sure the guide rail gib cams are properly adjusted. |

| ► Make sure the sole plate is not rocking on the guide rail. |
| ► Keep the blade depth consistent during the cut; don’t raise and lower the blade. |

| ► Make sure the blade is sharp. |
| ► Make sure the blade is installed correctly (not turning backward). |
| ► Reduce the motor speed. |
| ► If possible, increase the blade depth. |

| barely protruding below the surface. Increase the blade depth. |
Excessive chipping on the top edge | ► Make sure to use the correct blade for the type of material and type of cut. |
of the cut | ► Inspect the splinter guard. Make sure it is flush with the cut line for its entire |
| length. |
| ► Materials prone to splintering may splinter more if the blade is set too deep. |
