There are fourmold disks in use on many machines. The universal mold is now applied to all machines. "The universal mold disk has a long, narrow slot through which the ejector blades may be removed and inserted when it is turned into proper position.

If the blade does not advance easily, turn the mold disk slightly while pressing forward on the ejector lever. The ejector should project only about an inch beyond the mold face. Now, reach your right hand in alongside the mold slide and grasp the releasing lever and draw it to you. The ejector can now be withdrawn.
