Step 1: Power Off and Disconnect
- Turn off the tool and unplug or remove batteries to prevent accidental startup.
- Inspect the battery connections for dirt, debris, or corrosion.
Step 2: Check the Batteries
- Use a multimeter or the Milwaukee charger’s indicator to verify the battery voltage and health.
- If batteries are low or faulty, replace them with high-capacity batteries like the Milwaukee 48-11-1850R 5.0 Ah XC or the M18 REDLITHIUM HIGH Output XC 6.0Ah.
Step 3: Allow the Tool to Cool
If the tool feels hot, wait at least 15-20 minutes for it to cool down. Overheating can cause the motor to shut down temporarily.
Check for blocked vents or dust buildup and clean with compressed air.
Step 4: Inspect the Brush Assembly and Motor
- Remove the housing according to your model’s manual.
- Check the brushes for excessive wear; replace if they are worn down beyond the recommended length.
- Ensure the motor windings are clean and free of debris.
Step 5: Test and Reassemble
After inspecting and replacing necessary parts, reassemble the tool, insert the batteries, and test the operation. If stalling persists, consider professional service or replacing the motor.
