Pump faster, but not too fast or your seal may get hot go pop like mine did
Once your at 100 bar, it will get harder but you just have to keep going and put as much weight on the down stroke as you can. I'm lucky (or not as the case may be) to find putting 190 bar is almost as easy as putting 10 bar in due to my build quantity; Not quality :laugh:
Another thing, check that the pressure guage and the pressure release screw on the pump are not leaking.
My guage is and if I leave it to stand, I do loose pressure *note to self, get a new guage tight
