Danny ran out of cutting line with the trimmer. This was the first time we ran out since I bought the trimmer last year. It was not obvious how to wind the double-spool of line. Having no idea where the manual was, I quickly found it on www.poulan.com. The secret is to cut two lengths of 12.5 feet line, insert them in the anchor holes, and wind them at the same time. Each is locked in opposing threader notches that temporarily hold the line in place while the spool is replaced.
