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
9.The governor is now set.

NOTE:
1.Set the generator’s AUTO/OFF/MANUAL switch to AUTO.
2.Turn OFF the utility power supply to the transfer switch using the means provided (such as a utility main line circuit breaker).
3.The unit will start, and the transfer switch will transfer to standby.
4.Run the unit for one hour at 25 percent load.
5.Run the unit for one hour at 50 percent load.
6.Run the unit for one hour at 75 percent load.
7.Run the unit for one hour at 100 percent load.
8.Turn ON the utility power supply to the transfer switch, which will allow the transfer switch to transfer back to utility power. The unit will con- tinue to run for one minute and then shut down.
9.Allow the unit to cool.
10.Drain the oil and remove the oil filter. Replace the oil filter according to Section 4.4, “Changing the Oil Filter”. Replace the oil with synthetic oil as recommended in Section 4.3, “Changing the Engine Oil”.
11.The generator is now ready for service.
3.2USING THE AUTO/OFF/MANUAL SWITCH (FIGURE 3.1)
3.2.1 “AUTO” POSITION
Selecting this switch position activates fully automatic system operation. It also permits starting and exercising the engine every seven days with the setting of the exer- cise timer (see Section 3.6). This position also is used for remote starting, when it is set up.
3.2.2 “OFF” POSITION
This switch position shuts down the engine. This position also prevents automatic operation.
3.2.3 “MANUAL” POSITION
Set the switch to MANUAL to crank and start the engine. Transfer to standby power will not occur unless there is a utility failure.
Figure 3.1 – Generator Control Panel
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,
