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-

authorized service dealer.
NOTE:
Maintenance, replacement, or repair of the emis-

In order to assure peak performance of your engine, inspec-
tion of the engine exhaust port may be necessary after 50

to any non-road engine repair establishment, individual or

form this process yourself as engine damage may result from
contaminants involved in the cleaning process for the port.
