Installation 1. Move the ejector plate to the molding position (mold closed). 2. Move also the ejector cylinder rod to the fully retracted position. It is important to check by hand, that the rod is fully pushed back to the fully retracted position before measuring. 3. Measure the distance between the coupling and the ejector cylinder rod. 4. Extend the ejector cylinder rod

5. Move the mold ejector plates to the forward position (mold open). 6. Lock both the extra knock-out rod and at the other end the quick coupling. 7. Move the mold ejector plates back to the mold closed position and make the coupling between ejector plate and ejector cylinder rod. Make sure that the ejector plate and ejector cylinder rod are both in the mold closed position as soon as the coupling is made. If not, adjust.  Do not use with quick-change mold systems.
