Always service and repair a cool unit. Disconnect the
spark plug wire to ensure that the unit cannot start.
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.
