The following tables are adapted from the official manual. The tables here do not list every issue that you may encounter: if it's not here, you may find it in the manual. The manual will also provide detailed solutions.
Trouble | Probable Cause | Remedy |
---|---|---|
Finished stock is concave on back end. | Knife is higher than outfeed table. | Raise outfeed table until it aligns with tip of knife. |
Finished stock is concave on front end. | Outfeed table is higher than knife. | Lower outfeed table until it aligns with tip of knife. |
Finished stock is concave in the middle. | Both tables have too much end fall. | Raise both table ends using the adjustment screws below the tables. |
Ends of finished stock are cut more than the middle | Table ends are raised higher than the middle. | Lower both table ends using the adjustment screws under the tables. |
Chip out. | Cutting against the grain. | Cut with the grain whenever possible. |
Dull knives/inserts. | Sharpen or replace knives/inserts. | |
Feeding workpiece too fast. | Use slower rate of feed. | |
Cutting too deeply. | Make shallower cuts. | |
Knots, imperfections in wood. | Inspect wood closely for imperfections; use different stock if necessary. | |
Fuzzy grain. | Wood has high moisture content. | Allow wood to dry or use different stock. |
Dull knives/inserts. | Sharpen or replace knives/inserts. | |
Cutterhead slows while operating. | Feeding workpiece too quickly or applying too much pressure to workpiece. | Feed more slowly or apply less pressure to workpiece. |
“Chatter” marks on workpiece. | Knife/inserts incorrectly set. | Check that insert slots are clean and free of dust or debris. |
Feeding workpiece too fast. | Feed workpiece slowly and consistently. | |
Uneven knife marks on workpiece. | Knives/inserts are knicked, or out of alignment. | Replace knicked knives/inserts. |

Machine will not start/restart or repeatedly trips circuit breaker or blows fuses. | Overload automatic reset has not reset. | When jointer overloads on the circuit breaker built into the motor starter, it takes time for the machine to cool down before restart. Allow unit to adequately cool before attempting restart. If problem persists, check amp setting on the motor starter inside the electrical enclosure. |
Jointer frequently trips. | One cause of overloading trips which are not electrical in nature is too heavy a cut. The solution is to take a lighter cut. | |
Motor overheated. | Clean motor of dust or debris to allow proper air circulation. Allow motor to cool down before restarting. | |
Motor starter failure. | If you have access to a voltmeter, you can separate a starter failure from a motor failure by first, verifying incoming voltage at 230+/-20 and second, checking the voltage between starter and motor at 230+/-20. If incoming voltage is incorrect, you have a power supply problem. If voltage between starter and motor is incorrect, you have a starter problem. If voltage between starter and motor is correct, you have a motor problem. |
