My 1510N-7 of 15 yrs will have to be re timed just like this. It will work fine for a while then it stop's trimming. If I reset it just like this video it works again. It repeats this again. I can't figure out what is doing this. Very intermittent so it's hard for me to figure. Thanks for this video cause it helped me get my machine going again even thou it will repeat. Any tips?
