The operator worked at the grinding line 3. Before starting the production, he started to check the equipment. He set up the grinding equipment at speed level 15 (15 pushing bars/minute), took off the protection cover from the bottom side of the grinding charging table and he started to manually verify the pushing bars (by checking the bars with his hand). The machine was running in automatic mode. The operator wasn't sure if the pushing bar was tight and didn't remove is hand, the transport chain was still running. The transport system caught his right hand between the pushing bar and the frame of the machine. This caused contusion wound at the 3rd and 4th right hand finger.
