When I stop my B3030 on any slope at all, it will roll forward or backwards unless I set the brake. My BX23, that this 3030 replaced, did not move even on a pretty good slope when just left in gear. I had gotten so used to not needing to set the brake that I worry I will forget to set the brake on my 3030 and it will roll off. Is this normal or is there something wrong with the 3030?
