I soak them in petrol and then give them a good coating of aerosol spray grease - no need to be too particular about them.
One of the big maintenance issues with these is always over looked.....the mechanism hidden by the sole plate is often devoid of grease and you can do much worse than spread some more grease in. The drive mechanism is usually fine - it's the 'con rod' mechanism that really suffers - this makes the blades reciprocate.

Stihl actually supply a tube of 'special' grease that screws into the lubricant port.....it's hugely expensive and I find the lube doesn't go where it's actually needed anyway.
I drill and tap the blanking plug 6mm and insert a grease nipple and force the stuff in until it appears where the blades exit the casting....there isn't a seal in there so the casting doesn't over pressurise.
Taking the sole plate off allows you to spread grease where its needed - namely on the con rods which may or may not have roller bearings present. If they have rollers, they aren't captive

It's a bit of an oddball, that one.....the nearest I can get to is 11mm metric fine.
