Step 1: Verify Battery Power
- Ensure your batteries are fully charged using the included rapid charger.
- Remove the batteries from the tool and inspect for any signs of damage or corrosion.
- Reinstall the batteries firmly, making sure they click into place.
Step 2: Check for Overheating
If your tool stalls after continuous use, it might be overheating. Let the tool rest in a cool, dry place for at least 10-15 minutes before testing again. Overheating can cause the tool to temporarily shut down to prevent damage.
Step 3: Inspect the Brushes and Motor
- Disconnect power and remove the battery.
- Access the motor brushes (refer to your model’s manual for location).
- Look for worn brushes—if they are less than ¼ inch long, they should be replaced.
- Replace worn brushes or seek professional repair if the motor appears damaged.
Step 4: Clean and Lubricate
- Remove any dust, debris, or debris from vents and moving parts using compressed air or a soft brush.
- Apply appropriate lubricant to gears and moving components per the manufacturer’s instructions.
- Reassemble the tool and test its operation.
Additional Tips and Warnings
- Always wear safety glasses and gloves when inspecting or cleaning tools.
- Never operate the tool with damaged or frayed wiring.
- If troubleshooting does not resolve the issue, consult a certified Milwaukee service center.
