Question

All portable circular saws must be

Answer 1

Portable circular saws must have safety guards, including a fixed guard over the top and a retractable guard beneath to protect users from blade-related injuries.

Step-by-step explanation:

All portable circular saws must be equipped with safety guards to protect users from potential injuries. The guards typically consist of a fixed guard over the top of the blade and a retractable guard that covers the teeth of the saw blade underneath. This retractable guard automatically retracts as the saw is pushed into the material being cut and snaps back to cover the blade once the cut is complete. Additional safety features may include a safety switch or lock-off feature to prevent accidental start-up and electric brakes to quickly stop the blade when the trigger is released.
