Removed the bump knob, it was tight so I had to use a pair of pliers to loosen it. Then removed the trimmer line, then pulled the old spring out and then put the new one in by hand. Put the trimmer line back in and the bump knob back on. Tried the trimmer out to see if the line would advance and it did.
