diameter trimming line, loop it into two equal lengths.
Insert each end of the line through one of the two
holes in the inner reel (Fig. 14). Pull the line through
the inner reel so that the loop is as small as possible.

trimming line on the unit. The line may not
release properly if the line is too long.
