Which method helps avoid pull-in?

• A. Start cut with chainsaw at full throttle
• B. Use a wedge to open the kerf when needed
• C. Cut slowly to prevent binding
• D. Let the chain come to full speed before cutting

Answer: (B)

Pull-in happens when the kerf closes around the bar and the chain gets pinched, pulling the saw toward the cut and making control difficult. A wedge placed in the kerf as you cut pushes the wood apart, keeping the kerf open and preventing the bar from binding. This maintains smooth chain movement and reduces the force pulling the saw in. The other approaches don’t specifically address the pinching: starting at full throttle can worsen binding and control issues, cutting slowly doesn’t stop the kerf from closing, and waiting for the chain to reach full speed doesn’t prevent pinch either.
