7 Maintenance
Gearboxes and geared motors from Lenze are filled with a drive-specific and
design-specific lubricant filling at delivery. The mounting position and design are decisive
at ordering for the required lubricant quantity.
Note!
When changing the lubricant, Lenze recommends also changing the grease
packing of the bearings and replacing the radial shaft seal rings!
