Question about Powermatic 1791227K Model 64 10" Artisan Left Tilt Table Saw with 30" Accu Fence System

1 Answer

I have a Powermatic III Model 66 table saw with a 5 HP motor. Saw motor will not start unless I remove Switch Box cover and hold down the on switch. As soon as I let off the switch it comes back out and the saw shuts down. That is to say, the switch cannot hold itself in, at the on position. I'm wondering if the entire switch assembly has to be replaced or if it is repairable without a lot of work and trouble and buying a lot of various parts? Thank you

Replace the entire switch assembly, otherwise you will be doing a lot of work and buying individual parts that very well won't be available.

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.

SOURCE: I have recently purchased used powermatic 66 Table

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.

SOURCE: need motor cover for powermatic 66 table saw

I have seen a "buy it now" on Ebay for such a thing. Someone making a vacuum formed generic cover. Looks like it would work, even if it looks like a bubble-boy-solution.
Another solution I have seen is a wooden replica with louvers for ventilation.
Sheet metal would be a solution if you have a break and press to properly form, other wise it looks like you banged it our with a hammer and scrap metal.
I need the same thing and will probably to the wood with a paint that hides the fact...

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.

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.

You may have lost power on one of the wires to the motor. Check the wiring for breaks, if you have a meter make sure there is power to the 2 110 volt wires.

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.

Table saw capacitor heats up and explodes.


The wrong capacitor for one thing. There are starting caps and running caps. The starting cap is in the circuit for only long enough for the motor to get up to speed. If you have a Leeson motor that has a start and run cap then the run cap may not be the correct on. If you have a start cap blowing out I suggest you check the centriifugal switch in the end of the motor. It may have welded the contacts shut. In any case, I would take it to a motor shop .
