LINE INSTALLATION

This section covers both SplitLine™ and standard single line
installation.

Always use original equipment manufacturer 2.41 mm
(0.095 inch) replacement line. Line other than the specified may
make the engine overheat or fail.

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 clockwise (Fig. 23). 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. 23). 

3.

Remove spring from the inner reel (Fig. 23).

4.

Use a clean cloth to clean the the inner reel, spring, shaft
and inner surface of the outer spool (Fig. 24).

5.

Check the indexing teeth on
the inner reel and outer
spool for wear (Fig. 25). If
necessary, remove burrs or
replace the reel and spool.

NOTE:  

SplitLine™ 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 26
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 prop-
erly if the line is too long.

Single Line Installation

Go To Step 8 for SplitLine™ Installation

6.

Take approximately 5 m (16 feet) 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. 27). Pull the line through
the inner reel so that the loop is as small as possible.

7.

Wind the lines in tight even layers, onto the reel (Fig. 28).
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 12.

SplitLine™ Installation

8.

Take approximately 2.5 m (8 feet) of new trimming line.
Insert one end of the line through one of the two holes in
the inner reel (Fig. 29). Pull the line through the inner reel
until only about 4 inches is left out.

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
(Fig. 29).

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.
