Clean parts thoroughly using Cleaner. Ensure that all oil, grease, dirt etc. are removed. Dry thoroughly. Spray Penetrant on the surface to be inspected. Allow penetrant to act at a minimum of 10 minutes. Wipe off all the excess penetrant using dry rags. Dampen a rag with Cleaner and remove remaining surface penetrant smoothly. Let surface dry. Shake well before using the Developer can. Spray a thin film of developer on the surface. Two coats are sufficient. As the developer dries the bright red penetrant will bleed into the developer showing surface discontinuities (cracks, pits etc.).

To avoid blockage of developer’s can valve after using, turn upside – down the can and spray until clear “gas” comes out.
