How to lubricate seldén furlex 100 S furling system

My sailclub has a couple of school boats where people learn to sail, they just have some problems with the furlex on one of them.
The furlex does not turn very well sometimes so I grease up the whole system.
The halyard swivel is pretty dry so maybe here someting goes wrong, time will show if the system is working propperly so I'm excited to hear if someting is improved or not.
