Stop using it immediately. You are overheating the motor and bypassing the electronic safeguards. The smell is insulation burning. A fire risk is low due to protections, but damage is certain.
- Remove the battery. Place the drill in a safe, non-flammable area to cool.
- Let it cool completely for at least an hour.
- Inspect the air vents on the drill for blockage. Clear any sawdust or debris.
The noise and heat indicate excessive load. Causes: using a drill bit that's too large/dull, applying extreme side pressure, or running the drill continuously at low speed under high torque. The electronic system should cut power, but sustained abuse can overheat it before it trips.
IF THAT DIDN'T WORK: After cooling, try a different, simple task. If the noise and smell return immediately, the motor or internal components are damaged. Do not continue to use it.
HEADS UP: This is a tool, not a toy. Respect its limits. Use sharp bits, let the tool do the work without forcing it, and take breaks during extended use to allow heat to dissipate. Forcing it voids the warranty and creates a safety hazard.
