Step-by-step explanation:
The radial arm saw should be operated only after the operator has completed proper setup, safety checks, and received adequate training. It is critical to ensure that the work area is clear, the saw's blade is appropriate for the material being cut, and all safety devices are in place and functioning correctly. Additionally, the operator should wear necessary protective gear such as safety glasses, hearing protection, and avoid loose clothing that can get caught in the saw. Safety should always be the priority when operating any power tools, and by following these precautions, the risks associated with using a radial arm saw are greatly minimized.
