Do this by setting the generator’s main circuit breakers to their “OFF” (or open) position. 2. Refer to Part I, Section 2.5, “Starting the Generator” (Page 8), for cranking and starting instructions. The engine may require more cranking for initial starting since the fuel lines have to be primed (use of the primer switch will shorten this time). 3. Let the engine warm up for about five minutes to allow internal temperatures to stabilize. 4. Carefully inspect the engine/generator for fuel, oil and exhaust system leaks. Before proceeding to the next step, correct any leakage immediately. 5. When all tests and adjustments at no-load are completed, apply electrical loads and check for proper operation under load. See Section 3.4. Run the unit at least 30 minutes with loads applied. 6. Turn off all electrical loads by setting the generator’s main circuit breakers to their “OFF” (or open) position. 7. Let the unit run at no-load for a few minutes to stabilize internal engine/-generator temperatures. Then, shut down the engine. NOTE: The generator set was thoroughly tested and adjusted at the factory before shipping. No additional adjustment should be necessary. Only qualified service technicians who have been trained should perform adjustments outlined in this manual. 3.4 TESTING UNDER LOAD Apply electrical loads equal to about 75 to 100 percent of the unit's rated wattage/amperage capacity. Let the unit run at least 30 minutes with load applied. During this part of the test, check that the unit is not running excessively hot and that adequate cooling airflow is available. You must not allow the unit to overheat during prolonged operation. NOTE: The generator engine is equipped with a high temperature switch. The switch has normally closed (N.C.) contacts. When the engine temperature is too high, switch contacts close, and the engine shuts down automatically. GENERAC RECOMMENDS THAT YOU TEST THE GENERATOR FOR ADEQUATE COOLING. 36 Generac® Power Systems, Inc.
