Maintenance
MaintenanceSchedule
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.
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 TM and standard single
line installation.
Always use Genuine Factory Parts TM 0.105 in. (2.67 mm)
replacement line. Using line other than the specified may
make the engine overheat or fail.
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
