9.Push and hold MANUAL
10.Turn the service disconnect to the transfer switch off. After a short time delay, the transfer switch will connect to the generator.
11.Load generator to full load.
12.Connect an accurate frequency meter to the load side of the generator’s main circuit breaker. Frequency should be above 57.0 Hz.
13.If frequency is below 57.0 Hz, slowly rotate the governor adjustment nut or screw clockwise and/or counterclockwise until frequency is above 57.0 Hz.
14.Turn the service disconnect to the transfer switch on. The transfer switch will connect to the utility after five minutes.
15.After the engine has stopped running,
•If an adjustment was made in step 13, repeat steps 3 through 9.
•If an adjustment was not made in step 13, proceed to step 16.
IMPORTANT: If the no load frequency falls out of the no load parameter after full load adjustment is made, contact an authorized service center.
16.Reinstall the circuit breaker cover to the air intake guard.
17.Close the oil drain and control panel access doors.

See the Operator’s Manual for complete description of the home generator controls.
Operation
Automatic Operation Sequence
The generator’s control panel houses a logic control circuit board. This control board constantly monitors utility power source voltage. Should that voltage drop below a preset level, control board action will signal the engine to crank and start.
When utility source voltage is restored above a preset voltage level, the engine is signaled to shut down.
The actual system operation is not adjustable and is sequenced by sensors and timers on the control board, as follows:
Utility Voltage Dropout Sensor
•This sensor monitors utility source voltage.
•If utility source voltage drops below about 70 percent of the nominal supply voltage, the sensor energizes a 10 second timer. The timer is used to ‘sense’ brown- outs.
•Once the timer has expired, the engine will crank and start.
Utility Voltage Pickup Sensor
This sensor monitors utility power supply voltage. When that voltage is restored above 80 percent of the nominal source voltage, a time delay starts timing and the engine will go to engine
Engine Cool-down Timer
•When the load is transferred back to the utility power source, the engine
•The timer will run for about one minute, then the generator will stop.
•Minimum engine run time is 5 minutes.
