GENERATOR START-UP PROCEDURE (MANUAL)

6.The generator’s frequency meter (Figure 42) should be displaying the 60 cycle output frequency in HERTZ.

Figure 42. Frequency Meter

7.The generator’s AC-voltmeter (Figure 43) will display the generator’s output in VOLTS. If the voltage is not within the specified tolerance, use the voltage adjustment control knob (Figure 44) to increase or decrease the desired voltage.

8.The ammeter (Figure 45) will indicate zero amps with no load applied. When a load is applied, the ammeter will indicate the amount of current that the load is drawing from the generator.

Figure 45. Ammeter (No Load)

9.The engine oil pressure gauge (Figure 46) will indicate the oil pressure of the engine. Under normal operating conditions the oil pressure is approximately 28 to 85 psi. (193~586 kPa).

Figure 46. Oil Pressure Gauge

10.The coolant temperature gauge (Figure 47) will indicate the coolant temperature. Under normal operating conditions the coolant temperature should be between 167°~203°F (75°~95°C) (Green Zone).
