Why is it important to unplug tools before maintenance?

• A. To prevent accidental start-up and injury
• B. To save electricity
• C. To reset the tool's software
• D. To improve performance

Answer: (A)

Unplugging tools before maintenance is a safety action that prevents accidental start-up and injury. When a tool is connected to power, a switch can be bumped, a cord can be snagged, or a fault can energize the motor while you’re inspecting or adjusting internal parts. With power removed, moving components like blades or gears won’t start unexpectedly as you clean, lubricate, or replace parts or adjust guards. If you’re using a cordless tool, remove the battery to eliminate any stored energy. Saving electricity or resetting software aren’t the primary concerns here, and unplugging doesn’t improve performance.
