Could someone shed some light for me???

In days gone by I do the usual (old jam jar/bit of clear hose) and was always able to bleed system through without too much hassle, although I always think I could get them alot better!!
So I decided to buy the Motrax pneumatic pump which looks the business!! however I'm hitting a brick wall with it

There's instructions as to how to use, and one of the comments was look at Diagram 1 (no diagram anywhere?)

Anyway I plugged it on and released the bleed nipple, on squeezing the handle alot of air bubbles come through (great!!) but this goes on way too long and I've topped it up several times with air still coming through?? I believe that the air may be coming through the bleed nipples screw threads as it's alot stronger on pulling the fluid through. Do you reckon I need some grease around the threads to stop air coming through??

I thought this pump would aid me but im struggling at the moment
If anyone could point me in the right direction with this I'd be grateful.

cheers
Steve
