CoolIng
 
sysTem
Level 2.
Parts Required:   None, if you are careful.
IMPORTANT  
To maintain proper engine operating temperatures, cooling air 
must pass freely through the cylinder fin area. This flow 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 fins is 
considered “Normal Maintenance.”  Any failure attributed to lack of 
maintenance is not warranted.
Cleaning Grill
  1.  Remove accumulated debris from intake grill between backpack 
frame and blower housing.
