LINE INSTALLATION
Always use genuine Ryobi 0.080 inch (2.03 mm.)
replacement line. Larger line may make the engine
overheat or fail.

There are two methods to replace the trimming line.

reel, Part # 153577 can be purchased from your

Winding the Existing Inner Reel

6. Take approximately 25 feet (7.6 m) of new 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. 25). Pull the line through the inner reel so that
the loop is as small as possible.
NOTE: Always use the correct line length when installing
trimming line on the unit. The line may not
release properly if the line is too long.
4. Use a clean cloth to clean the the inner reel, spring,
shaft, and inner surface of the outer spool (Fig. 23).
