 === Table Tilt ===
-The bandsaw table can tilt up to 45 degrees. To use this feature, loosen the M8 nut handle (newly 3d printed after the loss of the original), and use both hands to gently rotate the table. Ensure that the two U-shaped metal spacers are parallel, and that the semi-circular support is sitting within the grooves of the black support pins. Tighten the M8 nut to secure.
