NOTICE
Impermissible mixing of roller bearing greases results in damage
Residual quantities of original oil can impair the specific properties of the new oil.
When regreasing, do not mix greases with a different soap base.
For regreasing, use lithium-saponified roller bearing grease NLGI 3/2.
Using a grease gun, inject the grease into the bearing point via the lubricating nipples
provided.
The grease quantities listed in the table are guide values.
