7.Turn utility power to the main distribution panel back on. This can be done by switching the ser- vice main breaker to the on or closed position. Allow the generator to shut down.

Do not make any unnecessary adjustments. Factory settings are correct for most applica- tions. However, when making adjustments, be careful to avoid overspeeding the engine.

If this procedure or equipment are not available, locate the nearest Service Dealer and they can per- form the adjustments.

NOTE:

A service fee may be charged for this adjustment.

2.Completely remove the idle spring.

3.With governor arm at wide open throttle position, rotate governor shaft fully clockwise. Tighten clamp bolt to 84 inch-pounds.

4.Start unit and apply full load. Use full load speed adjust screw (Figure 3.4) to adjust frequency to 58 Hz.

5.Remove load, stop engine, loosen the idle adjust screw and reconnect the idle spring.

6.Using a hand, push the governor arm to the closed throttle position. Make sure the idle spring does not stretch at all.

7.Restart the unit.

8.Slowly turn the idle adjust screw to adjust the no- load idle frequency to 63-63.5 Hz.

9.The governor is now set.

‹3.7.1 ADDITIONAL CORROSION PROTECTION

Periodically spray all engine linkage parts and brack- ets with corrosion inhibiting spray such as WD-40®or a comparable product.

3.8VOLTAGE REGULATOR

ADJUSTMENT

With the frequency between 62-63.5 Hertz, slowly turn the slotted potentiometer (Figure 3.5) until line voltage reads 244-252 volts.

NOTE:

Remove the access panel on top of the control panel to adjust the voltage regulator.

adjust voltage.

NOTE:

The voltage regulator is housed above the generator's control panel. The regulator maintains a voltage in direct proportion to frequency. For example, at 62 Hertz, line-to-neutral voltage will be 124 volts.
