 IMPORTANT 
 To maintain proper engine operating temperatures, cooling air must
pass freely through the cylinder n area. This ow of air carries
combustion heat away from the engine.
Overheating and engine seizure can occur when:
•  Air intakes are blocked, preventing cooling air from reaching the 
cylinder.
•  Dust and grass build up on the outside of the cylinder. This build up 
insulates the engine and prevents the heat from leaving.
Removal of cooling passage blockages or cleaning of cooling ns is 
considered “Normal Maintenance”. Any failure attributed to lack of 
maintenance is not warranted.
