Which of the following is an acceptable practice to enhance safety when using a chainsaw?

Locking the left elbow while cutting helps maintain control of the chainsaw and provides stability during operation. This practice ensures that the operator can use their body to effectively absorb any kickback or movement from the saw, reducing the risk of losing control. A locked elbow promotes better posture and keeps the saw aligned with the cut, which is crucial for precise cutting and safety.

Employing this technique allows the operator to maintain a firm grip and proper body mechanics, which are essential when operating power tools. By ensuring that the arms and body are in a stable position, the operator can respond more effectively to unexpected situations that may arise during use, such as kickback or uneven cutting surfaces.
