Safety should always be a priority when using a table saw and crosscut sled. To ensure a safe working environment, follow these precautions: always wear appropriate personal protective equipment, such as safety glasses and hearing protection. Additionally, keep your hands and fingers away from the saw blade while operating the sled. Use a push stick or push block to guide the workpiece and maintain a firm grip on it. Regularly inspect your sled for any damage or wear and tear, and make necessary repairs or replacements as needed.
