Warm tip：
*Worn brushes can cause the motor to smoke or spark and should be replaced if it occurs.
*When replacing carbon brushes,be sure to inspect your armature for burns, cracks, or other damage which can indicate larger motor problems that may not be solved by replacing the carbon brushes.
*After replacing new carbon brushes, if it doesn't take a few minutes or hours for the carbon brushes to wear out or wear in half, it means your rotor is bad. Please replace the rotor promptly.
*Can repair intermittent carbon brush motors and restore their operation.
