AC VOLT METER (3) has increased to its approximate rated value, and engine has reached stable operating speed.
3. Release MASTER SWITCH (1) to PRIME AND RUN position. If operating with an auxiliary fuel source, rotate
MASTER SWITCH to PRIME AND RUN AUX FUEL position.
4. Check COOLANT TEMP (4) [170-200F (77-93C)] and OIL PRESSURE GAUGE (2) [25-60 psi (172-414kPa]
indicator readings.
5. Adjust VOLTAGE potentiometer (5) until AC voltmeter (3) indicates 208VAC.
6. Loosen frequency control locknut (6) and adjust the frequency adjust control knob (7) until frequency gauge (8) indicates
60HZ. Tighten locknut (6).
7. Place AC CIRCUIT INTERRUPT switch (9) to CLOSED position.
