## Narrative

Mechanic was replacing the fittings on the circle of the 14H blade. After replacing the fittings, he put the line up bar into the hydraulic swivel valve to secure it. The valve slipped off the bar when he attempted to bolt the valve back into place. He reached out to grab the valve to prevent it from falling. The valve landed on the palm of his hand, overextending his arm.
