Troubleshooting: Mechanical & Electrical Problems
Trouble
Board thickness does not match digital display
Chain jumping
Machine will not start/restart or repeatedly trips circuit breaker or blows fuses.
Probable Cause | Remedy | |
|
| |
Digital display not calibrated properly. | Follow calibration procedures. | |
|
| |
Inadequate chain tension. | Adjust chain tension. | |
|
| |
Sprockets misaligned. | Align sprockets. | |
|
| |
Sprockets worn. | Replace sprockets. | |
|
| |
No incoming power. | Verify unit is connected to power, and | |
main switch is set to “I”. | ||

|
| |
| When planer overloads on the circuit | |
| breaker built into the motor starter, it | |
| takes time for the machine to cool | |
Overload automatic reset has not | down before restart. Allow unit to | |
reset. | adequately cool before attempting | |
| restart. If problem persists, check | |
| amp setting on the motor starter | |
| inside the electrical enclosure. | |
|
| |
| One cause of overloading trips which | |
| are not electrical in nature is too | |
| heavy a cut. The solution is to take a | |
| lighter cut. If too deep a cut is not the | |
| problem, then check the amp setting | |
Planer frequently trips. | on 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. Check amp setting on | |
| motor starter. | |
|
| |
| Verify that planer is on a circuit of | |

there is probably a loose electrical | ||

lead. Check amp setting on motor | ||
| ||
| starter. | |
|
| |
| Go through all 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. | |
|
| |
| Examine motor starter for burned or | |
| failed components. If damage is | |
| found, replace motor starter. If motor | |
| starter looks okay but is still suspect, | |
Motor starter failure. | you have two options: Have a | |
| qualified electrician test the motor | |
| starter for function, or purchase a new | |
| starter and establish if that was the | |
| problem on changeout. (continued) | |
