DIY users unable to safely diagnose and fix tool equipment failures without expert guidance

DIY enthusiasts and homeowners lack reliable ways to identify whether their power tools are safe to use when they malfunction, leading to potential safety hazards and wasted time troubleshooting. Current solutions require either expensive professional repair services, trial-and-error experimentation that risks injury, or searching through fragmented online forums with inconsistent advice. This creates anxiety around tool safety and prevents people from completing projects efficiently.
