Cooling System

Level 2.
Parts Required:
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. Brush accumulated debris from intake grill between backpack frame

Cleaning Cylinder Fins
1. Disconnect spark plug lead from

entering the engine.
