I bought a new Echo PAS 260 Power Source with the Echo Pro Trim Trimmer attachment and several other attachments to go with it. My local dealer recommended this trimmer. It was working great until the orange trimmer line that came with it ran out. I bought some Titanium replacement trimmer line. I don't know if it's the Titanium Line, the trimmer it self or if it is me. But I rap it around the head like the directions say and the way the dealer showed me to do it. Sometimes it will work but it seems to run for a short time then the string breaks off inside the head. The trimmer has a dual feed. Two strings. Sometimes just one breaks off in the head but usually its both. Then I have to stop trimming and rewrap the string. It's really a time killer. Is it me or is this a common problem or could it just be the titanium string?
