SECTION 7: MAINTENANCE AND REPAIR INSTRUCTIONS
5. Check the indexing teeth on the inner reel and outer
spool for wear. If necessary, remove burrs or replace
the reel and spool. See Figure 29.
NOTE: SplitLine™ can only be used with the inner reel
containing slotted holes. Single line can be used
on either type of inner reel. Use Figure 30 to
identify the inner reel you have.
Indexing Teeth
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.

6. Cut approximately 25 feet (7.6 m) of new trimming
line, then 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 31.

7. Wind the lines in tight even layers onto the reel. See
Figure 32. 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.
SplitLine™ Installation
8. Cut approximately 12 feet (3.65 m) of new trimming
line. Insert one end of the line through one of the two
holes in the inner reel. Pull the line through the inner
reel until only about 4 inches is left out. See Figure 33.
9. Insert the end of the line into the open hole in the
inner reel and pull the line tight to make the loop as
small as possible. See Figure 33.

10. Before winding, split the line back about 6 inches.
11. Wind the line in tight even layers in the direction
indicated on the inner reel.
NOTE: Failure to wind the line in the direction indicated will
cause the cutting attachment to operate
incorrectly.
12. Insert the ends of the line into the two holding slots.
See Figure 34.
13. Insert the ends of the line through the eyelets in the
outer spool and place inner reel with spring inside
the outer spool. See Figure 35. Push the inner reel
and outer spool together. While holding the inner reel
and outer spool, grasp the ends and pull firmly to
release the line from the holding slots in the reel.
