As above advice please?

How do you check the oil level, what level should it be and what kind of oil?

There's a level/filler plug on the side of the 'box.
It doesn't hold much.
I got mine from Quaiffe themselves, you can order off their website - I think it's Silkolene, the website will tell you what grade.
