5. If the voltage is not within the specified tolerance, use
the voltage adjustment control knob (Figure 54) to
increase or decrease the desired voltage.

6. The ammeter (Figure 55) 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 55. Ammeter (No Load)
7. The engine oil pressure gauge (Figure 56A) will
indicate the oil pressure of the engine. Under normal
operating conditions the oil pressure is approximately
35 to 65 psi. (193~586 kPa).

8. The coolant temperature gauge (Figure 56B) will
indicate the coolant temperature. Under normal
operating conditions the coolant temperature should
be between 185°~207°F (85°~97°C).
9. The tachometer gauge (Figure 56C) will indicate the
speed of the engine when the generator is operating.
Under normal operating conditions this speed is
approximately 1800 RPM's.
10. The generator load gauge (Figure 57) Indicates the
generator load rate. It is recommended the load be
above the red area (20%) for maintaining sufficient
exhaust temperature.

11. Place the main, GFCI, and aux. circuit breakers in the
ON position (Figure 58).
12. Observe the generator's ammeter (Figure 59) and
verify it reads the anticipated amount of current with
respect to the load. The ammeter will only display a
210
current reading if a load is in use.
