To prevent binding when using a rotary saw, what is the recommended starting speed?

  1. 1800 rpm

  2. Maximum rpm

  3. 2000 rpm

  4. 1500 rpm

The correct answer is: Maximum rpm

The recommended starting speed for a rotary saw to prevent binding is the maximum rpm of the tool. When operating power tools like a rotary saw, starting at maximum speed allows for optimal cutting performance and efficiency. This high rotational speed helps ensure that the blade engages the material effectively, reducing the risk of the blade being pinched or binding during operation. If the saw is started at a lower speed, there is a greater chance that the material being cut could cause the blade to stall or jam, leading to increased wear on the tool and potential safety hazards for the operator. Furthermore, operating at maximum rpm ensures that the saw can maintain its cutting speed even under load, which is crucial for effective cutting through various materials.
