Powermatic Saws - Page 2 - Recent Questions, Troubleshooting & Support

L Luke, closest I could find is May 1983. http://vintagemachinery.org/pubs/655/6140.pdf

Have you squared the fence to the blade/table. If the table is true to the blade, your mitre slot should also be. You can then squre your fence to the slot

Here is a link to the Accu-fence manual. It Includes the adjustments. From you description I think you will find that the adjustments will solve your problem http://content.powermatic.com/assets/manuals/2195075Z_man_EN.pdf

if its cutting in the angle. maybe the teeth on your blade are dull on one side and the blade is pulling material to the side. maybe the fence is ok.

Switches are very common devices, and can be purchased in many configurations. Remove the switch and search the following places: www.digikey.com www.mouser.com

I am going to try something. I used to use Powermatic machines, and was invited to tour the factory and was given a week long all-expense-paid training seminar in 1990. I recommend that you contact by e-mail or phone the company or one of it's service center, as I found them to be incredibly helpful. Type it into your "search engine". Be blessed.

Ok, basic question...is the lock engaged? It is the small knob at the center of the adjustment wheel. Is it possible the screw has been galled? Here is the manual- http://content.powermatic.com/manuals/1791227K_man.pdf

I believe that that model of Powermatic has a lock for the blade angle that also extends and retracts the casters for moving the saw. You may have unlock or change the handle position to allow for blade angle adjustment. You can get a manual or information at the Powermatic website to show you how to change the settings on the saw. Hope that helps.

Try lubricating with silicone spray. I use it for just such things, and I'm happy with how it works. Also, clean and lubricate the lock on the elevation control.

Bob, I just bought one of these saws 2 weeks ago (1997 Model) I have it completely disassembled as of right now. There is a worm gear that drives a very large set of teeth attached to the trunion. Mine were completely clogged and full of crud that the mechanisim would barely turn. I am thinking the teeth on the worm gear or trunion at the 90 degree end need to be cleaned to allow it to hit its full range of motion, Its also possible the teeth on one of these pieces is cracked or broken. I would try cleaning them. If you cant get to them, the cast iron top comes off fairly easily. # bolts hold the right wing to the main top and 3 bolts hold the main top to the cabinet. Of course if you have rails, these need to come off first. I have attached images of the before and after of cleaning these parts so you can see if they are really bad like mine, it could be your problem, Hope this helps

As you only have 4 wires from the motor it should be straight forward as two would be from the start winding (Black and red) and the other the run winding (White with yellow stripe and Blue). You should be able to check this with a tester as there should only be continuity between the wires as mentioned above. Reference the thermal switch, I am not 100% sure on the color codes but have attached a diagram which should help but will advise as best as I can on the connection. The diagram is for a high/low voltage but you can disregard the winding on 3 and 4 but should help on the understanding. Join the blue and black wire from the motor together and connect to the black wire from the supply. You should be able to run the motor (Excluding the thermal switch) by connecting the White with yellow stripe and the red wire together along with the white from the supply. To include this switch I would presume that you would connect the red wire from the motor to the brown wire from the thermal switch, the yellow wire from thermal switch to the White with yellow stripe from the motor and finally the white wire from the thermal switch to the white from the supply.

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.

You can only tell by using a continuity tester or a multimeter and some troubleshooting techniques.
