GENERATOR START-UP PROCEDURE (MANUAL)
7. The generator’s frequency meter (Figure 43) should be
displaying the 60 cycle output frequency in HERTZ.
Figure 43. Frequency Meter
8. The generator’s AC-voltmeter (Figure 44) will display
the generator’s output in VOLTS. .
Figure 44. Voltmeter
9. If the voltage is not within the specifi ed tolerance, use
the voltage adjustment control knob (Figure 45) to
increase or decrease the desired voltage.

10. The ammeter (Figure 46) 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 46. Ammeter (No Load)
11. The engine oil pressure gauge (Figure 47) 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 47. Oil Pressure Gauge
12. The coolant temperature gauge (Figure 48) will
indicate the coolant temperature. Under normal
operating conditions the coolant temperature should
be between 167°~203°F (75°~95°C) (Green Zone).
Figure 48. Coolant Temperature Gauge
13. The tachometer gauge (Figure 49) will indicate the
speed of the engine when the generator is operating.
Under normal operating conditions this speed is
approximately 1800 RPM’s.

14. Place the main, GFCI, and aux. circuit breakers in the
ON position (Figure 50).

Circuit Breakers (ON)
15. Observe the generator’s ammeter (Figure 51) 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.

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