Which of the following increases the risk of blade twist during cutting?

Blade twist during cutting primarily occurs when the saw blade is not properly aligned or stabilized, which can lead to dangerous inaccuracies in the cutting process. Poor blade guide adjustment is crucial because the blade guides are designed to support the blade and keep it straight during operation. If these guides are misaligned or improperly adjusted, they fail to provide adequate support, allowing the blade to flex or twist, especially under pressure or when encountering harder materials. This instability directly increases the risk of blade twist, resulting in compromised cut quality and increased safety hazards.

Using a push stick, maintaining proper speed, and using a sharp blade are generally practices that contribute to safer and more effective cutting operations. A push stick helps keep hands away from the cutting path, proper speed promotes efficient cutting without unnecessary strain on the blade, and a sharp blade reduces friction and the likelihood of binding or stalling. None of these factors contribute to an increased risk of blade twist when properly executed, thus highlighting the importance of good blade guide adjustment as a key factor in maintaining cutting precision and safety.
