2. Check for Overheating or Overload
Allow the tool to cool down if it has been working hard or overheating. Overloading can trigger safety shut-offs, causing stalling. Use the tool within recommended capacities and avoid continuous heavy use without breaks.
3. Inspect the Brushes and Motor
- Remove the motor housing per the user manual instructions.
- Check the brushes for wear; replace if they are less than ¼ inch long.
- Look for debris or dust buildup around the motor and clean carefully.
4. Clean and Lubricate Moving Parts
Use a soft brush and compressed air to clear dust from vents and gears. Apply a small amount of manufacturer-recommended lubricant to moving parts to ensure smooth operation.
5. Test with a Different Battery or Tool
- Replace the current battery with a fully charged, known-good battery, such as the Milwaukee 48-11-1850R 5.0 Ah XC battery.
