used very recently Make sure caps are tight on M/C and on unit. Set to around 1bar does not take too many pumps to get up to pressure - if it does tighten the caps Make sure the cap supplied fits your M/C Enabled me to bleed all the brakes out after fitting new M/C callipers and rear cylinders on my own. Best to put plenty in the reservoir tank to ensure continuous operation whilst bleeding the system out. worth the money and well made in my opinion for single workshop bleeding - also the recetical for the fluid at the nipple is also good.
