First Run-up For 3 1/2 Years

Ladies and gents, any suggestions please?
I'm about to try and fire up the TT600. I've refreshed the oil and filter but is there an easy access way of getting some oil pressure up before letting the engine run (assuming it will)?
Cheers.

 

Thanks grandad. I had the thought that the chances of the thing starting straight up were very unlikely so gave it a whirl and it actually took a seven or eight spins to get a small backfire. Any way, I've had it running, oil light went out after one or two seconds.
