This was suggested by Tina as her method of cutting and Graphtec have agreed with this method, until they can get something official printed up I've copied Tina's idea here.

If you are getting wads of card stuck inside your blade housing and wrapping around the blade, try increasing the number on the ratchet blade by 1 unit to lift the plastic part of the blade housing away from the surface of your card so it won't catch on any small bits that might lift off the carrier sheet, BUT decrease your cutting pressure to compensate so you don't damage your carrier sheet and blade. Test cutting is advised using a curvy font until you become used to using this method.
