I never noticed that my Poitras R-arm saw was out of adjustment until I bought Freud’s 90 tooth cross-cut blade. It cuts beautifully, except that the first inch or two burns in hardwood. I discovered that the blade is dog-tracking a wee bit. The manual doesn’t describe adjustments much more than to say everything is factory set and should be good forever. I think the adjustment is made with two small set-screws that turn with a small allen wrench. Both screws will loosen, but neither will tighten, even when the other is loose. I can feel that forcing them will likely cause my little allen wrench to snap, and these screws are about an inch inside the casting (I’d never get the broken piece out again).

Any advice will be appreciated (unless it starts something like, “I’ve never seen such a saw before, but . . . .)

Any luck figuring this out?. I just bought one and have to check the settings and yes the owners manual sucks!

Yes, I figured it out. There may be a better way, but this way worked:

1. The manual tells you how to do all the adjustments except the one I had trouble with. Start by making sure all those adjustments in the manual are done.

2. To correct the ‘dog tracking’ loosen the motor just a little. There are 6 nuts holding the motor (two of them are under the plate (part no. 580-01).

3. Put a mark beside one of the teeth on the saw blade using a felt pen. Set a square against the fence and then with the saw off set the square so the marked tooth just touches the edge of the square, then pull the saw toward you and turn the blade to see if the same tooth still touches the square without moving the square. I used a square with a short blade so that I could pull the saw toward me or slide it back without the arbor bumping into the square. (You could set up something more convenient, like a block of wood with a screw in it that just touches the marked tooth). You have to twist the loosened motor so that the marked tooth just grazes the square in both positions. It’s a pain in the ass to keep moving the motor a tad, snugging up the nuts and trying it again and again until you get it just right. However, once it’s done you’ll think it was well worth the trouble.

4. Curse me out for not having taken photos of how I set it up (I know my instructions are hard to follow. I did my best). Good luck with it. Let me know how you made out.

Have your say...
