Rotary saws are treated as a standard feature that attaches to the engine’s drive system, meaning every engine is described as capable of using one. In this context, the saw is not just an extra or rare accessory but a common component across engines, so it’s present rather than optional or limited to certain models. The idea that only select engines have rotary saws would restrict applicability and contradict how the material presents them. Likewise, saying they aren’t installed on any engine or that they’re optional would conflict with the notion of universal availability described here.
