What should be the first action if a power tool malfunctions during use?

When a power tool malfunctions during use, the first action should always be to unplug it and inspect for issues. This is crucial for safety reasons; unplugging the tool ensures that it cannot accidentally start while you are examining it. Safety is a primary concern when dealing with malfunctioning equipment, as continuing to use the tool or attempting to fix it while it is still plugged in could lead to serious injuries or accidents.

Inspecting the tool allows the user to determine the nature of the malfunction, whether it is a simple issue like a jammed part or something more serious that requires professional attention. By addressing the issue directly after ensuring that the tool cannot power on, users safeguard themselves from further risks and can make informed decisions on how to proceed with repairs or whether to seek professional assistance.
