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. 

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.

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. 15). 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. 16). 

3.

Remove spring from the inner reel (Fig. 16).

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. 17). If necessary, remove burrs or replace the
reel and spool.
