 Note!
Clean roller bearings before applying new grease!
The following lubricant quantities are required:
¯ For fast−running bearings (drive−end gearbox): fill approx. one−third of the hollow
space between rolling bodies with grease.
¯ For slow−running bearings (within gearbox and driven side of gearbox): fill
approx. two−thirds of the hollow space between roller bearings with grease.
