True or False: Very few portable power tools such as drill motors and rivet guns require periodic maintenance.

The statement that very few portable power tools, such as drill motors and rivet guns, require periodic maintenance is false. Regular maintenance of portable power tools is crucial for ensuring their longevity, reliability, and safety during operation. Tools like drill motors and rivet guns, which are commonly used in aerospace assembly, often experience wear and tear due to their frequent use in high-stress environments.

Routine maintenance tasks may include checking and replacing brushes, lubricating moving parts, tightening screws, and inspecting cords for damage. Neglecting these maintenance procedures could lead to decreased performance, increased risk of malfunctions, or even accidents during use. Therefore, it is essential to acknowledge that a significant number of portable power tools do indeed require regular maintenance to ensure optimal functionality and safety.
