I purchased the polar bear series hybrid table saw last fall. I have it plugged into 220 and it runs smooth and quiet. However, when I rip even half inch osb it bogs down and I have to constantly stop and let the motor catch up. I thought maybe the blade was our of alignment so I purchased a dial and set it up to check the blade. When I rotated the blade forward to check the clearance, the blade spun backward when I let go. Is this normal? My blade is a little out of align but not so much I thought it would be the issue. I’m using the standard blade that came with the saw. I’ll switch to a diablo soon but I’d like to get this issue fixed first.

Any thoughts?

Usually the belt is too loose if it bogs down. Check to see if its tight and the nut tightened down.

Like Chuck said, check the belt for slippage. If it’s good, then grab a meter and verify that you have 240v at your outlet and switch on your saw. Trying to run a saw wired for 240v on 120v will do exactly what you describe. It might be that one leg is not making a good connection or a wire has come loose somewhere.

As for the belt moving backwards when you move it, yes, that is pretty normal. To avoid that, and make things a bit more accurate as well, turn the blade by moving the motor pulley instead of grabbing the blade to do it.

Cheers,
Brad

Check the belts, voltage coming in, connections, capacitors, fix the alignment, and hang that stock blade on the wall.

Everything knotscott said! And the stock blades I don’t think would slow down the unit without smoking the wood a bit from dull cutters. Sounds like something down under.

Thanks everyone for your input. I did see that the belt was loose and I tightened it. A quick check ripping a board and it seems to have done the trick. I’ll have more time to tinker in a week or two.

Thanks again.
