*Grinder will not start - Check power supply, plug, and switch; inspect for blown fuses or tripped breakers.
*Motor hums but wheel does not turn - Inspect for jammed wheel, loose drive components, or capacitor failure.
*Excessive vibration - Verify wheel balance, check for worn bearings, and ensure grinder is securely bolted to pedestal.
*Wheel wobbles - Check wheel flanges, spindle threads, and wheel seating; replace damaged wheels.
*Overheating motor - Reduce load, check ventilation, and inspect for blocked air passages or over-tensioned bearings.
*Poor grinding performance - Dress the wheel, verify correct wheel type for material, and replace if worn or glazed.
