I just spoke to Bosch and they claimed there is no service bulletin associated with the 4100 tablesaw. Disappointed with Bosch! If Im grown up enough to use a tablesaw then I suppose Im grown up enough to be able to tear it down and repair it.
Check the threaded rods that turn to move the motor assembly up and down. These rods are sometimes oiled or greased and this just attracts saw dust and eventually binds up the system. Clean as best you can and the threads they turn in to raise the blade. Also check the tilt rods. Another thing to check is the joints everything pivots on. Occasionally a small peice of wood can get in just the right (or wrong) place and the motor assembly won't move because it's blocking the pivot points.
