## Narrative

EE cut off his right middle finger while working on the hp-500 bowl. Crew was changing out the wear liners in the bowl of the HP-500. Nuts were placed under the bottom of the new liner to give the bowl clearance off the floor to allow adjustments. Grease is used to seal leaks. The grease created suction. When it released, the bowl dropped & amputated his finger.
