While using a round bar to remove a bucket pin, a worker's fingers were crushed between the bucket pinhole and the bar.

To remove the bucket from the arm of a machine, a worker pulled out the link pin and then tried to use a round bar to remove the bucket pin. As soon as the pin came out, the arm lifted, raising the round bar and crushing the worker's fingers between the pinhole and the bar.

Corrective Action
1. When removing a pin, check that the pinhole is centered (in this case, by slightly adjusting the position of the arm).
2. Use a round bar that is considerably longer than the pin, and be careful not to get your hands too close to the pinhole.
