NOTE: Maintenance, replacement, or repair of the emission control devices and system may be performed by any non-road engine repair establishment, individual or authorized service dealer.

In order to assure peak performance of your engine, inspection of the engine exhaust port may be necessary after 50 hours of operation. If you notice lost RPM, poor performance or general lack of acceleration, this service may be required. If you feel your engine is in need of this inspection, refer service to any non-road engine repair establishment, individual or authorized service dealer for repair. DO NOT attempt to perform this process yourself as engine damage may result from contaminants involved in the cleaning process for the port.

LINE INSTALLATION

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

Always use original equipment manufacturer 0.080 in. (2.03

mm)replacement line. 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 (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 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: 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 19 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.
