old lubricants before they are greased.
Clean with a soft, lint-free cloth and non-abrasive cleaning agents. Check the compatibility of the clean-
ing agent with the materials to be cleaned.
Thin grease film outside
A film of grease covers the external surface so that the grease colour tarnishes the surface slightly.

Apply the grease with a soft brush or similar.
