MAINTENANCE AND REPAIR INSTRUCTIONS

MAINTENANCE SCHEDULE

Perform these required maintenance procedures at the frequency stated in the table. These procedures should also be a part of any seasonal tune-up.

NOTE: Some maintenance procedures may require special tools or skills. If you are unsure about these procedures take your unit to any non-road engine repair establishment, individual or authorized service dealer.

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.

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 0.105 in. (2.67 mm) replacement line. Other types of line 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 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 spring from the inner reel (Fig. 27).

4.Use a clean cloth to clean the 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.
