Step 2: Allow the Tool to Cool
If the tool has been used intensively, it may overheat and trigger a safety shutoff, causing stalling. Let the tool rest for at least 10-15 minutes to cool down before testing again.

- Disconnect the tool from power and remove any accessories.
- Use a brush or compressed air to clear dust and debris from vents, brushes, and motor area.
- Check for damaged or worn brushes—replace if necessary.
