Make sure you have original DeWALT batteries
Color: Yellow
I thought there was something wrong with the edger but it was the batteries. Must use original DeWALT batteries. I have cheap replacement batteries that work fine for all my DeWALT tools but do not work with this edger. Will run for a few seconds and shut off. With original DeWALT batteries, this edger works great.

Descent tool.
Definitely won't go as far as the add says on a fully charged battery. But works good never the less.
