What to do if the cutting head on my Ryobi 150r Trimmer will not advance line?

If the cutting head on your Ryobi Trimmer won't advance the line, several issues could be the cause: * The cutting head might be bound with grass. If so, stop the unit and clean the cutting attachment. * The cutting head could be out of line, requiring you to refill it with new line. * The inner reel might be bound up; try replacing it. * The cutting head might be dirty. Clean the inner reel and outer spool. * The line could be welded. Disassemble, remove the welded section, and rewind the line. * The line might be twisted from when it was refilled. Disassemble and rewind the line. * Not enough line might be exposed. Push the Bump Knob and pull out line until 4 in. (102 mm.) of line is outside of the cutting attachment.
