10 inch lest tilt Unisaw will not tilt to complete verticle --only goes to 88.5.

There is an adjustment under the table top. It usually is a bolt with a lock nut that allows you to adjust the table to a predetermined angle every time. You can adjust the amount that the table will go by unlocking the lock nut and then turning the bolt the correct direction allowing the table to come to a full 90 degrees. Once you have the table a 90 degrees lock the bolt down with the lock nut. This will aloow you to change the tilt of the table to something other than 90 degrees and then come back to the 90 degrees by turning the adjusting wheel until it bottoms out against the locked doen adjusting bolt.
