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

Table not parallel to cutterhead.

Adjust table/cutterhead parallelism.

 

 

Depth of cut scale is incorrect.

Inadequate tension.

Adjust chain tension.

 

 

Sprockets misaligned.

Align sprockets.

 

 

Sprockets are worn.

Replace sprockets.

 

 

No incoming power.

Verify power connections to planer.

One cause of overloading trips which
