When the twine tubes rotate all the way down, the twine knife clamps should be fully open and touching each other. If they are only partially open they will snap shut before the twine tubes pass them. If you look under the knife mechanism you will notice an arm attached to one of the clamps pivot shaft. You should also see two plates which will contact the roller on that arm. One of the plates open the clamps and the other closes the clamps. Those plates are slotted so you just loosen the nuts and slide them so they fully open the clamps when the twine tubes are all the way down and close the clamps after the twine tubes are past.

On my old 848 I had the clamps that Mike it talking about bind up and not fully open. Clean and lubed them to get them working. Arms may also be out of adjustment.
