True or False: Low-velocity tools can be operated without pressing against a surface.

Low-velocity tools are designed to operate effectively at lower speeds and typically require contact with a surface for proper functioning. When these tools are pressed against a surface, they create the necessary force to perform tasks such as fastening or cutting. Operating them without pressing against a surface could lead to inefficient operation and may not yield the desired results since these tools rely on that contact to achieve optimal performance.

The nature of low-velocity tools means they are generally not intended for operation in mid-air or without support, as doing so could be unsafe and ineffective. Each tool has specific operating guidelines that generally emphasize contact with the work surface for safety and performance reasons.
