wire, chain or rope. These can break off and
become dangerous projectiles.

• Wind the inner reel with new line
• Install a prewound inner reel

NOTE: Maintenance, replacement, or repair of the emis-
sion control devices and system may be per-
formed by any non-road engine repair establish-
ment, 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.
2. Remove the inner reel from the outer spool (Fig. 13).
3. Remove spring from the inner reel (Fig. 13).
4. Use a clean cloth to clean 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. 14). If necessary, remove burrs or
replace the reel and spool.
