Nh br 740 baler issues

Looking at buying a nh br 740 and i got to run it some yesterday. Made 71 rolls and i ran into some issues. For one it does not seem to cut the net good, to me the cuts are real ragged, even with some long tails dragging behind the baler. The next issue i encountered was the buzzer would go off to wrap the wrapping process would start and it was like it lost power or something cause the monitor would start over and the wrapping process continued. I would have to manully rasie the rollers and duckbill assembly, dump the bale and cut the wrap, then start over. It appears its a loose connection possibly because if i unplugged and replugged the baler back in i would be ok for awhile. It only done it 4 times out of the 71 rolls, but im curious as to what could be going on. Any ideas?
