3. Turn the ignition key to the start position (Figure 40).
Once the engine starts, release the ignition key and allow
it to return to the rUn position (Figure 38).
If the engine fails to start after 10 seconds, wait
approximately 30 seconds and repeat steps 3-4.

4. Let the engine run for 1-2 minutes. Listen for any
abnormal noises. If any abnormalities exist, shut down
the engine and correct the problem.
5. The generator's frequency meter (Figure 41) should
be displaying the 60 cycle output frequency in herTZ.

6. The generator's aC-voltmeter (Figure 42) will display
the generator's output in voLTS..

7. If the voltage is not within the specified tolerance use
the voltage adjustment control knob (Figure 43) to
increase or decrease the desired voltage.

8. The ammeter (Figure 44) 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.
9. The engine oil pressure gauge (Figure 45) will
indicate the oil pressure of the engine. Under normal
operating conditions the oil pressure is approximately
28 to 71 psi. (193~490 kPa).
10. The coolant temperature gauge (Figure 46) will
indicate the coolant temperature. Under normal
operating conditions the coolant temperature should
be between 165°~203°F (74°~95°C) (green Zone).
Figure 46. Coolant Temperature Gauge
11. The tachometer gauge (Figure 47) will indicate the
speed of the engine when the generator is operating.
Under normal operating conditions this speed is
approximately 1800 RPM's.
