NOTE: Always use the correct line length when
installing trimming line on the unit. The line
may not release properly if it is too long.
Single Line Installation
Go To Step 8 for Membrane Line Installation.
6. Take approximately 40 feet (12.2 m) of new
trimming line and loop it into two equal lengths.
Insert each end of the line through one of the two
holes in the inner reel. Pull the line through the
inner reel so that the loop is as small as possible.
See Figure 15.

5. Check the indexing teeth on the inner reel and
outer spool for wear. See Figure 13. If necessary,
remove burrs or replace the reel and spool.

Use Figure 14 to identify the inner reel you
have.

7. Wind the lines in tight even layers, onto the reel.
See Figure 16. Wind the line in the direction
indicated on the inner reel. Place your index finger
between the two lines to stop the lines from
overlapping. Do not overlap the ends of the line.
Proceed to step 11.
