| Problem | Probable Cause(s) | User-Reported Solution(s) | | :--- | :--- | :--- | | | Worn or flat-spotted yellow tire on drive wheel. | Replace yellow tire or entire wheel assembly. Solution: Always disengage feed when not in use. | | Machine blows fuse on startup | Disintegrated urethane cover on feed rollers causing binding. | Replace the urethane covers on the feed rollers. | | Digital LED display not turning on | Loose connection; Incorrect 24VAC transformer tap configuration for shop voltage. | Check connections in electrical cabinet. Verify 24VAC transformer output matches requirements. | | Machine producing a "spring joint" | Infeed and outfeed tables are not coplanar. | Adjust outfeed table height slightly and re-test with a long straight edge; may require loosening multiple adjustment bolts. | | Loud grinding noise from motor | Loose motor fan. | The fan can fall off the motor shaft. Requires accessing the motor from underneath the machine; a fixable by replacing the fan. | | Thicknesser table adjustment grinding/skipping | Table is out of alignment; mechanical issue in lift mechanism. | Check for debris and re-lubricate. May require professional service to re-align and adjust the thicknesser table mechanism. | Shift the feed speed selection lever to either
