True or False: You should check the new grinding wheel for proper speed rating and size before replacement.

The statement is true because ensuring that a new grinding wheel has an appropriate speed rating and size before replacement is crucial for safe operation and effective performance. Each grinding wheel is designed for specific speeds and sizes, which are essential for preventing accidents and equipment failure.

If a wheel is operated above its maximum speed, it can break apart due to centrifugal forces, posing significant risk of injury to the operator and damage to the machinery. Additionally, using a wheel that is not the correct size for the grinder can lead to improper fitting, reduced efficiency, and potential hazards during operation.

Therefore, always checking the specifications of the grinding wheel against the machine's requirements is a fundamental safety and operational practice in mechanical work.
