I was taught that is the correct method. Tighten up by hand as much as possible without extra leverage and smack the end of the thread a sharp blow and repeat the operation.
I actually thought that was frowned upon.Didn't realise we were talking about hydraulic pullers, from the original post I assumed conventional screw pullers.
