Hi CheshamMow, and welcome to TGMF.
I would just do a visual inspection of the cutting cylinder and make sure none of the welds are broken, or blades bent.
Then start by backing off the adjustment each side so the bottom blade moves away from the cylinder, see if it all turns normally and then adjust the bottom blade so it's just touching the cylinder blades all the way across. If sharp enough you should be able to cut strips of paper while setting it up.
