To get rid of stiff links the chain cracker (or chain tool, whatever you want to call it) has two sets of prongs which you can locate between the chain side plates. Those at the opposite end from the tightener are what you use when pressing the pin out, or when pressing it back in. You then flip the tightener over to the other side of the chain and locate the chain on the prongs nearest the tightener. Just the slightest pressure on the pin will then push it back a little through the side plate in the opposite direction (the pin moves through one sideplate, not the other as that is free floating), and ... bingo - no more stiff link!
