Line Installation; Winding The Existing Inner Reel; Single Line Installation - Troy-Bilt TB475SS Operator's Manual

LINE INSTALLATION
This section covers both Membrane line and standard
single line installation.
Always use manufacturer's 0.095 inch (2.41 mm)
replacement line. Using line other than specified may
make the engine overheat or fail.
I,_ ARNING: Never use metal-reinforced line,
wire, chain, or rope, etc. These can break off
and become dangerous projectiles.

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. 16). 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. 17).
3. Remove spring from the inner reel (Fig. 17).
4. Use a clean cloth to clean 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. 18). 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 18 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. 20). Pull the line through the inner reel so that
the loop is as small as possible.
