Final answer:
To perform a crosscut with a radial arm saw, secure the wood, use the fence as a guide, and follow safety precautions.
Step-by-step explanation:
When performing a crosscut with the radial arm saw, it is essential to prioritize safety and accuracy. A radial arm saw is a versatile machine that allows for a variety of cuts, but when it comes to crosscutting, the blade moves across the wood grain to produce a shorter cut. While performing a crosscut, you should ensure the piece of wood is securely clamped and that you are using the saw's fence as a guide for straight cuts. Additionally, always keep hands and fingers away from the blade and wear appropriate safety gear.
