Line Installation

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

Always use Genuine Factory Parts™ 0.080 in. (2.03 mm) replacement line. Using line other than the specified may make the engine overheat or fail.

WARNING: Never use metal-reinforced line, wire, chain or rope. 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. See Figure 17. 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. See Figure 18.

3.Remove spring from the inner reel. See Figure 18.

4.Use a clean cloth to wipe the inner reel, spring, shaft, and inner surface of the outer spool.
