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.

7. The engine oil pressure gauge (Figure 56) will
indicate the oil pressure of the engine. Under normal
operating conditions the oil pressure is approximately
42 to 86 psi. (290–590 kPa).

8. The coolant temperature gauge (Figure 57) will
indicate the coolant temperature. Under normal
operating conditions the coolant temperature should
be between 167°–194°F (75°–90°C).

9. The tachometer gauge (Figure 58) will indicate the
speed of the engine when the generator is operating.
Under normal operating conditions this speed is
approximately 1,800 rpm.

11. Observe the generator's ammeter (Figure 60) 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.
