What is the primary reason you should never lift or carry an electric hand tool by its service cord?

Lifting or carrying an electric hand tool by its service cord can cause significant damage and safety hazards. When you use the cord to lift or carry the tool, it places undue stress on the connections between the cord and the tool. This can lead to the cord being pulled off its terminals, which may result in a short circuit. A short circuit could create a dangerous situation, such as electrical shock or a fire hazard.

Ensuring that you handle tools by their handles or designated grips keeps the cord intact and reduces the risk of accidental disconnections or damage. This is critical for maintaining safety standards while working with electrical equipment.
