Abstract: On the afternoon of October 14, 1994, a logging crew, of Wimer Logging Co., was preparing to lower a Thunderbird TY90 yarder to move it to a new sale. Employee #1 was helping the superintendent raise the yarder's A-frame and attach it to a pole. Employee #1 was standing on the running board next to the guyline drums on the left side of the pole. He was waiting for the superintendent to move the A-frame up so he could insert the pins. The superintendent activated the switch for the A-frame, but nothing happened. While the superintendent looked at the switch to see why it was not working, Employee #1 moved up onto the guyline drum and placed his right hand near the pin on the pole. The A-frame kicked in, slid up the yarder and struck the pin. The collar that secures the pin then came down, striking Employee #1's two little fingers and severely lacerating them.
