1.2.3 Cleaning and greasing
Cleaning
The components must be thoroughly cleaned to remove all foreign particles, machining residues and
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.
Extremely thin grease film
A barely continuous film of grease covers the bearing surface so that a continuous film of grease exists;
however, there is no detectable darkening due to the grease colour.
Recommendation:
Apply the grease with a paint brush, a fine bristle brush or similar. Remove surplus grease by wiping off
once with the respective system components.
Thin grease film
A film of grease covers the bearing surface so that a continuous film of grease exists and the grease
colour darkens the surface slightly.
Recommendation:
Apply the grease with a paint brush, a fine bristle brush or similar.
Thin grease film outside
A film of grease covers the outer surface so that a continuous film of grease exists and the grease colour
darkens the surface slightly.
Recommendation:
Apply the grease with a paint brush, a fine bristle brush or similar.
