Powermatic 66 wiring problem

SOURCE: My Powermatic 66 table saw won't start.

Your saw motor is equipped with a two speed internal start switch. Over time saw dust will get into the contacts and cause the points to burn. You can pull the end off of the motor and take some 400 grit sandpaper to the contacts to clean them( there are two sets of contacts one works in the out position the other in the in position) it will be the set in the in position that is the problem. Gentle clean them, reassemble the motor end cap and it will work fine. I have to do this about once a year to my saws. I use my saws about 25 hours a week. I have been doing this to one of my Powermatic saws for 31 yrs. now.

That is the current setting for a motor-starter which is an overcurrent sensor. This is a circuit breaker like device that usually has a heater coil that opens a contact which cuts the power to the relay that powers the motor to prevent overload damage to the motor.

The dial is in AMPS and should be set just slightly higher than the nameplate amp rating for the motor.

You have a bad capacitor or a fouled starting winding centrifugal switch. The switch contacts can be cleaned and burnished and you can pick up a new cap from e-bay. It is most likely the switch. This requires motor disassembly. If you are not familiar with the process, take it to a motor shop. The switch is in the back end of the motor and is attached to the end cover. Sawdust in the motor, even though it is TEFC, it will get dust in it causes this condition.

Check to make sure the arbor set screw is not loose. The bearings may have shifted when you moved it. I recently rebuilt an old 66. Repositioning the bearings and tightening the set screw could be all it needs.
