Step 2: Allow the Tool to Cool Down
If the tool has been used intensively, it may overheat. Turn off the tool, disconnect the battery, and let it cool for at least 10-15 minutes before trying again. Overheating can trigger safety features that cause stalling.
Step 3: Clean Vents and Contacts
- Use compressed air to blow out dust from vents and motor areas.
- Inspect the contacts where the battery connects; clean with a dry cloth if dirty or corroded.
Step 4: Check Internal Components
For experienced users, open the tool casing carefully to inspect brushes, wiring, and motor parts. Worn brushes or loose connections can cause stalling. If unsure, consult a professional technician.
Step 5: Test and Confirm
Reassemble the tool, insert a fresh or fully charged battery, and run a test. If the tool still stalls, consider replacing internal parts or consulting Milwaukee customer service.
