Question about Powermatic 66 10" 3 HP 1 Phase 230V Table Saw w/ 30" Accu-Fence & Rout-R-Lift 1660806K

2 Answers

My Powermatic 66 table saw won't start. Tried to turn on my Powermatic 66 table saw this morning. Blade moved one half inch as if trying to start. Tried reset button on motor, still nothing.  I believe it may be the electronic starter, but unsure how to test.

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.

Solution 1 hit the nail on the head. I recommend blowing out the windings while you are at it and sealilng up the ********** (junction box) with RTV. I see a lot of these machines that have been wired half assed and end up with a 2 screw connector on the JB. This lets in dust and this is picked up by the internal motor fan and distributed in the motor. Cleaning out the motor will make it last much longer and may even prenvent a fire.

Powermatic 66 wiring problem


Simple solution: switch two of the wires. Doing so will reverse the direction of the motor. You can switch it at the motor or on the electrical plug end.

I have a powermatic 66 table saw. I removed the motor, to move the saw. when i reinstalled the motor, the blade has moved 5/16'' towards the fence.


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.

I am thinking that you have mistakenly crossed 2 or more wires, hopefully you wrote yourself a wiring diagram or there is one inside the motor cover. I don't know if I can find a wiring schematic for this tool. If you still have the owners manual look in there for initial setup and see if they provided one. If you need more help let me know and I will do what I can.

My Powermatic 66 tablesaw has a 3 phase 230 Vac motor on it but I cannot tell if it is a 3 hp or 5 hp. All the tags are gone from the motor. Is there any way to tell from the serial number? 8666-1008.


There will be a tag on the motor that will give the specs. Sometimes they are hard to see from the underside and its not easy to remove the top see them. Try lowering the motor (with blade removed) all the way and use a digital camera to reach up into the cabinet and photoqraph the top of the motor. I had to take several since your shooting blind to get a picture of mine.

I am trying to find out how old my powermatic 66 table saw is. serial no is 97661400


On the Powermatic 66's the first two numbers are the year in which it was made, so yours was made in 1997. The second set of two numbers is the model. The last numbers I"m unsure of but its my understanding that they represent the manufactured number, so yours was the 1,400th saw made for that year.

I have a Powermatic 66 that trips breaker


Either it has a problem with a blade brake or the motor is siezing. Or the is a wiring problem. With the unit unplugged check and see if you can turn the blade by hand, if not the motor is the problem. If it does you could still have a motor problem by it drawing to much amperage or the is a wiring problem.
