Hi there,
I've got an annoying problem with the pump of my HK500 and I thought maybe someone could help...
It used to work nicely since I bought it some months ago, but now the pump gets harder and harder to use until it gets "stuck" in. When finally I'm able to move it again, it does not pump anymore. I tried to open it , adjust the rubber and it works for 20-30 pushes, but then it starts again
Has anymore here experienced this problem ?
Thks
Anthony
