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.

Thanks John
AS I have a stihl its has a screw in grease entry point where I screw in grease tube and put a measured amount every 4 months.
The Jonseed cutter ( 20+years old) has a grease nipple I use that to grease the same

In my case (Chinese Qualcast), it was a bevel gearing system which failed, where the motor shaft end drives the bevel gear. The bevel gear wasn't making full contact - I managed to botch it by packing the gear a bit higher to mesh better, but I don't expect it to continue to work for long.
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

So I take it there is not a grease nipple to fit straight into the blanking plug.

I'm not sure what this thread is.
It's a bit of an oddball, that one.....the nearest I can get to is 11mm metric fine.

Have you tried an Imperial nipple? 3/8" bsf or maybe a UNF thread?
Not that one particularly....I have a large box of metric and similarly imperial nipples and the 10 is too slack (there isn't a 12mm) and nothing else comes too near.
As it's a European machine (Austrian) I thought that metric was almost for certain.....they do use metric fine elsewhere.
