MAINTENANCE & 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.
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 0.095 in. (2.41
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).
