LINE INSTALLATION
This section covers both SplitLine™ and standard single line installation.
Always use original equipment manufacturer 0.105 in. (2.67 mm)
replacement line. Other types of line 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. 27). 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. 27).
3. Remove the spring from the inner reel (Fig. 27).
4. Use a clean cloth to clean the inner reel, spring, shaft and inner surface
of the outer spool (Fig. 28).
5. Check the indexing teeth on the inner reel and outer spool for wear (Fig. 29).
If necessary, remove burrs or replace the reel and spool.

MAINTENANCE AND REPAIR INSTRUCTIONS
WARNING:
To prevent serious injury, never perform
maintenance or repairs with unit running. Always service and
repair a cool unit. Disconnect the spark plug wire to ensure
that the unit cannot start.
WARNING: Never use metal-reinforced line, wire, chain or
rope. These can break off and become dangerous projectiles.
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.
