✔ Ejection Pin
If the ejection pin is not recovering after pushing out through the cutting tip, a small amount
of lubricant may be used in the mechanism. Take the cylindrical cutting assembly cap off
and spray or drop silicon lubricant (like WD40) down the shaft of the ejection pin (where
the spring is). Manually work the mechanism by pushing down on the top of the ejection
pin. It may also help to take the cutting tip off and clean it out with the alcohol and wire
method recommended above.
