CAUTION:
- Maintain low speed drill rotation when inserting or removing the cleaning tool to prevent axial scratches which may cause future leaks.
Polish for one minute at moderate speed (less than 1,500 rpm) or until the surface is clean and free of scratches or foreign material.
Clean the fitting with a lint-free cloth.
Inspect the surface for grooves or scratches. If grooves or scratches are still present, install a new component.
