So I bought a T230 trimmer used, really cheap. Thought it would make a good backup machine, but have found that its so light I rather use it and save the wear and tear on my FS90R, which btw weighs like 100 pounds. Anyway, I havnt used the shindy much but I can not figure out how to put the line in. It is a bump head. What is happening is that it constantly is feeding out line (doesn't have a shield). The head has arrows pointing in both directions for winding line and no divider to separate the left line from the right. Can anyone help? Is the head just no good?
