Troubleshooting: Mechanical and Electrical Problems
Trouble
Uneven depth of cut side to side.
Board thickness does not match depth of cut scale.
Chain is jumping.
Machine will not start/restart or repeatedly trips circuit breaker or blows fuses.
Probable Cause | Remedy | |
|
| |
Knife inserts not set correctly. | Make sure knife inserts are set | |
correctly and securely in cutterhead. | ||
| ||
|
| |
Planer table not level with cutterhead. | Level the table. See pages | |
|
| |
Depth of cut scale is incorrect. | Adjust depth of cut scale. Use LED | |
control panel for greater precision. | ||
| ||
|
| |
Inadequate chain tension. | Adjust chain tension. | |
|
| |
Sprockets misaligned. | Align sprockets. | |
|
| |
Sprockets worn. | Replace sprockets. | |
|
| |
No incoming power. | Verify machine is connected to power. | |
|
| |
Stop button is still engaged. | Rotate stop button to disengage. | |
|
| |
| When the planer overloads on the | |
| circuit breaker built into the motor | |
| starter, it takes time for the machine | |
Overload automatic reset has not | to cool down before restart. Allow | |
reset. | machine to adequately cool before | |
| attempting restart. If problem persists, | |
| check amp setting on the motor | |
| starter inside the electrical box. | |
|
| |
| One cause of overload trips which are | |
| not electrical in nature is too deep a | |
| cut. The solution is to take a lighter | |
| cut. If too deep a cut is not the | |
| problem, check the amp setting on | |
Planer frequently trips. | the overload relay. Match the full load | |
| amps on the motor as noted on the | |
| motor plate. | |
| If amp setting is correct, then there is | |
| probably a loose electrical lead or a | |
| failed component. See items below. | |
|
| |
| Verify that planer is on a circuit of | |

there is probably a loose electrical | ||

lead. Check amp setting on motor | ||
| ||
| starter. | |
|
| |
| Go through all of the electrical | |
| connections on the planer including | |
| motor connections, verifying the | |

| of electrical arcing which is a sure | |
| indicator of loose connections or | |
| circuit overload. | |
