A valve for the lid lift sys. on a ISC 77 crusher stuck in the open position letting the pressure off the hydraulics. This allowed the lid to descend. Employee didn't install the safety pin in the lift system to prevent this before doing maintenance. As they moved the lid over for inspection, it descended unnoticed and pinched EE's finger between the lid and a hold down loop.
