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

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.
