When using a circular saw, which of the following is correct?

Starting the cut only when the blade is at full RPM is crucial for better control and safety. When the blade is fully sped up, it operates at its optimal cutting performance, allowing for a smoother and cleaner cut. It minimizes the risk of the saw binding or kicking back, which can occur if pressure is applied while the blade is still accelerating. This practice also helps reduce the likelihood of injury, as the operator can maintain a stable grip on the saw and the material being cut.

The other practices, such as starting the cut slowly before the blade reaches full speed or bypassing safety features like the guard, compromise safety. Additionally, cutting through material without checking for obstacles could lead to harmful accidents or damage to the saw itself. Effective and safe tool operation guidelines emphasize the importance of allowing the tool to reach its optimal operating speed before beginning the cut.
