Loop
There are two methods to replace the trimming line.
• Wind the inner reel with new line
• Install a prewound inner reel
Winding the Existing Inner Reel
1. Hold the outer spool with one hand and unscrew
the bump knob counterclockwise (Fig. 6-1).
Inspect the bolt inside the bump knob to make sure
it moves freely. Replace the bump knob if
damaged.
2. Remove the inner reel from the outer spool (Fig. 6-2).
3. Remove spring from the inner reel (Fig. 6-2).
4. Use a clean cloth to clean the the inner reel, spring,
shaft, and inner surface of the outer spool.
5. Check the indexing teeth on the inner reel and
outer spool for wear (Fig. 6-3). If necessary, remove
burrs or replace the reel and spool.
NOTE: Membrane line can only be used with the
inner reel with the slotted holes. Single line can be
used on either type of inner reel. Use Figure 6-4 to
identify the inner reel you have.
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. Take approximately 20 feet (6.1 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. 6-5). Pull the line through the inner reel so
that the loop is as small as possible.
