Contractor Sawstop Blade won't stay raised.

[chase standifer]

I had a sawstop activation the other day, completely my fault, I was going to cut some aluminum but I guess it was no longer in bypass mode. Anyway when I changed out the blade the blade seemed to shift down some and I had to re-adjust my riving knife. Now the blade will not stay raised, I can spin the height adjustment and the gears inside seem to work but the blade it self pivots on some other point and doesn't move up or down the brake and other parts seem to move. When the blade does goes up it just falls back down after a few seconds. Any help would be appreciated. I would hate to not be able to work this weekend while I wait for them to open on Monday. It is a Contractor model.

I have the PCS but, assume it is similar to that described in the manual:

1. Reset the Retraction of the Arbor Block: During normal use, the arbor block is held in place by a
spring-loaded support mechanism called the retraction bracket. When the brake is activated, the angular
momentum of the spinning blade is transferred to the arbor block, causing it to drop out of the retraction
bracket.
To reset the arbor block into the retraction bracket, turn the elevation handwheel counter-clockwise until
the lower elevation limit stop is reached. The arbor block will automatically engage the retraction bracket.
Now turn the elevation handwheel clockwise to raise the arbor block and blade. You can also reset
the arbor block manually by pulling the arbor sharply upward until you feel the arbor block engage the
retraction bracket.

Glenn is exactly right. In my case when I called Saw Stop we had to use the manual system to reset it. Be advised it will take a really hard tug to do it!

Good luck!

That was exactly the problem, there was some sawdust build up that was preventing the arbor from going low enough. Thanks for the help not sure how I missed that in the manual.

Glad it was a simple fix. Good dust collection will help with these sorts of things if available. Obviously DC is a problem on the job site.

Yeah I am working with a shop vac and cyclone set up right now, it does ok. Of course it seems to work best when I remember to switch the hose between tools.
