5. The generator's AC-voltmeter (Figure 41) will display
the generator's output in volTs. If the voltage is not
within the specified tolerance,

6. Use the voltage adjustment control knob (Figure 42)
to increase or decrease the desired voltage.

7. The ammeter (Figure 43) 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 43. Ammeter (No Load)
8. The engine oil pressure gauge (Figure 44) will indicate
the oil pressure of the engine. Under normal operating
conditions the oil pressure is approximately 35 to 65
psi. (193~586 kPa).

9. The coolant temperature gauge (Figure 45) will
indicate the coolant temperature. Under normal
operating conditions the coolant temperature should
be between 180°~225°F (75°~95°C) (green zone).

10. The tachometer gauge (Figure 46) will indicate the
speed of the engine when the generator is operating.
Under normal operating conditions this speed is
approximately 1800 RPM's.

12. Observe the generator's ammeter (Figure 48) 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.
