5.The generator's AC-voltmeter (Figure 33) will display the generator’s output in VOLTS. If the voltage is not within the specified tolerance, use the voltage adjustment control knob (Figure 34) to increase or decrease the desired voltage.

8.The coolant temperature gauge (Figure 37) will indicate the coolant temperature. Under normal operating conditions the coolant temperature should be between 180~221 °F (82~105 °C), Green Zone.

Temperature Gauge

9.Thetachometergauge(Figure38) will indicate the speed of the engine when the generator is operating. Under normal operating conditions this speed is approximately 1800 RPM’s.

	ON position (Figure 39).

6.The ammeter (Figure 35) 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.

7.The engine oil pressure gauge (Figure 36) will indicate the oil pressure of the engine. Under normal operating conditions the oil pressure is approximately 35 to 65 psi. (241~448 kPa). When starting the generator.

11. Observe the generator's ammeter (Figure 40) and verify it reads the anticipated amount of current with respect to the load. The ammeter will only display a current reading if a load is in use.

12.The generator will run until manually stopped or an abnormal condition occurs.
