Final answer:
Before using a radial arm saw, ensure the work area is clean, the blade is properly installed and sharp, safety devices are in place, the material is secure, and personal protection is used.
Step-by-step explanation:
Before making a cut with the radial arm saw, you should ensure that the area is clear of debris and that the blade is properly installed and sharp. Make sure all safety devices are in place, and that you have set the correct blade depth to avoid cutting beneath the workpiece. Also, firmly secure the material being cut, use proper eye and ear protection, and understand the operation of the saw. Verify that the saw's guard operates correctly and that you have a clear understanding of the feed direction.
