What does "push back" refer to when operating a chainsaw?

"Push back" refers to a situation where the top bar of the chainsaw experiences pinching or binding during a cut, causing the saw to pull back towards the operator. This occurs when the cutting chain gets trapped, usually at the rear section of the cut, resulting in the force of the saw being directed back to the user rather than forward through the material being cut. It emphasizes the importance of maintaining control and awareness while operating a chainsaw, as improper handling during this type of incident can lead to dangerous situations, including loss of control and potential injury. Understanding "push back" is crucial for safe chainsaw operation, as it teaches operators the need for proper positioning and cutting techniques to mitigate this risk.
