Hydraulic Clutch Fluid Issue

Personally, I've never bothered to pre-fill an Oberon slave and wouldn't attempt it. You can fill it in situ just from the master, or if you are very particular you can connect it up to the hose and master but hold the slave up in the air to help with purging it. It really is very simple.

Any tiny bubbles will run back up the pipe overnight and can be purged just by tickling the lever without going for a full stroke. Please: no-one suggest the tie-wrap on the lever overnight because that just dissolves the air into the fluid since there is nowhere for the air to escape. It may give a firm lever action but dissolved air can come back out of solution, just like bubbles in the blood of a diver.
