## Narrative

Three MTMs were in the process of changing wear steel on 082-25 crusher. The injured leaned on the adjustment cap guide to see if the bowl had disengaged from the mainframe. At the same time, the adjustment cap/bowl shifted pinching EE's left thumb. This resulted in a ""U"" shaped laceration approximate 2.5"" over the end of the left thumb.
