## Narrative

Employee was assisting others with a drive shaft installation on a washing screen.  While he was tightening a bolt, the chain holding the counterweight slipped off, allowing the counterweight to rotate clockwise pinching his finger between it and the impact wrench.  This caused him to receive a laceration and fracture to his left index finger.
