When the blade is running and hits metal or when finger is within 1 inch to the running blade, the brain will be triggered to stop the blade. It sounds like a gun shot. This time the blade hit aluminum.
The new blade and brain are picked up from WoodCraft in Woburn, MA. The nut is tightened very tightly to secure the new blade.
Then install the brain below the blade. That T-handle hex wrench adjusts the height of the brain. It shall be 1/16" to 3/32" to the blade according to user's manual.
Shut every door around the blade, then install the cover, adjust height. The cover is flush to the table top of the saw. Dry run SawStop to double check before cutting anything. Off running buddy! Thank you for your company!
