COOLING INTAKE/OUTLET Air intake and outlet openings in the generator compartment must be open and unobstructed for continued proper operation. This includes such obstructions as high grass, weeds, brush, leaves and snow. Without sufficient cooling and ventilating air flow, the engine/gen- erator quickly overheats, which causes it to shut down. (See the installation diagram.)  The exhaust system parts from this product get extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system. INSPECT COOLING SYSTEM Inspect engine cooling system. See the Service Schedule. • Check hoses for damage, deterioration, leaks, etc. Correct any • discrepancies found. Check hose clamps for tightness. • 10-1 Maint030 Rev. A 10/10 Maintenance
