wrench,  25 - 50 mm (1 - 2 in.) cleaning brush.

Parts Required:   None.

IMPORTANT  
To maintain proper engine operating temperatures, cooling air must 
pass freely through the cylinder fi n area. This fl 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 debris 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 and cleaning of cooling fi ns is 
considered “Normal Maintenance.”  Any failure attributed to lack of 
maintenance is not warranted.

1.  Periodically blow dirt and debris off cooling fi ns with a compres-

sor and safety nozzle, or;

2.  Remove engine and muffl er covers, and brush off dirt and debris 

using the medium bristle brush.
