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 a Troy-Bilt or other
qualified 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.
AIR FILTER MAINTENANCE
Cleaning the Air Filter
Clean and re-oil the air filter every 25 hours of operation. It is an important
item to maintain. Failure to maintain your air filter properly can result in
poor performance or can cause permanent damage to your engine.
Open the air filter cover. Push the locking tab on the under side of
the cover inward. Then pull the air filter cover out and up. (Fig. 22).
