Maintenance
9.1 Inspection and maintenance
These greases have lithium soap as the thickening agent and mineral oil as the base oil. They
exceed the standard requirements of DIN 51825 in several important respects and are,
therefore, compatible with the specified relubrication intervals.
Note
Damage due to mixing grease types
Mixing greases and oils which are based on different types of soap or oil can degrade their
lubrication properties. Mixing low-temperature grease with normal temperature grease can
cause lumps to form in the lubricant. The consequence can be damage to the roller bearings
due to overheating.
Never mix greases that have different thickening agents and different base oils.
Regreasing
The regreasing intervals are specified on the lubricant plate of the machine. If the specified
number of operating hours is not reached within three years, regrease the bearings at the main
inspection.
If you use other KP2N greases, some of which only meet the minimum requirements per DIN
51825, halve the regreasing intervals.
1. Clean the lubricating nipple and press in suitable grease. The shaft should rotate so that
The used grease collects outside the bearing.
After several regreasing operations, remove the spent grease depending on the specified
relubrication intervals. To do this, loosen the outer bearing cover.
9.1.9
Touch up any damaged paintwork
If the paint is damaged, it must be repaired in order to protect the unit against corrosion.
Note
Paint system
Contact the Service Center (Page 117) before you repair any damage to paint. They will provide
you with more information about the correct paint system and methods of repairing paint
damage.

the new grease can be distributed throughout the bearing. The bearing temperature rises
sharply at first, then drops to the normal value again after the excess grease has been
displaced out of the bearing.
