lubrication. Use mineral oils for lubricating the machine. Before adding grease clear the lubrication
points. The lubrication should be performed according to fig. 5.
Use the ŁT-4S-3 once per season.
The hubs of the harrow disks must be lubricated twice per year:
+ before the spring season,
+ before the autumn season.
