Section 3 — Operation
9.Allow the unit to cool.
10.Set the generator’s main circuit breaker to its OFF (or OPEN) position.
11.Set the generator's AUTO/OFF/MANUAL switch to OFF. Remove the 7.5A and 15A fuses from the generator control panel. Disconnect the battery cables as outlined in “General Hazards” (page 2).
12.Drain the oil and remove the oil filter. Replace the oil filter according to Section 3.4, “Changing the Oil Filter”. Replace the oil with synthetic oil as recommended in Section 3.3, “Changing the Engine Oil”.
13.Reconnect the battery cables as outlined in “General Hazards” (page 2) and insert the 7.5A and 15A fuses into the generator control panel. 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 auto- matic system operation. It also permits starting and exercising the engine every seven days with the set- ting of the exercise timer (see “Setting the Exercise Timer” section). 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.
15 kW Generator
With the switch set to AUTO, the engine may crank and start at any time without warning. Such automatic starting normally occurs when utility power source voltage drops below a pre- set level or during the normal exercise cycle. To prevent possible injury that might be caused by such sudden starts, always set the switch to OFF and remove both fuses before working on or around the generator or transfer switch. Then, place a “Do Not Operate” tag on the generator panel and on the transfer switch.
3.3AUTOMATIC TRANSFER
OPERATION
To select automatic operation, do the following:
1.Make sure the transfer switch main contacts are set to their UTILITY position, i.e., loads con- nected to the utility power source (Figure 3.2).
2.Be sure that normal utility power source voltage is available to transfer switch terminal lugs N1 and N2.
3.Set the generator’s AUTO/OFF/MANUAL switch to AUTO.
4.Set the generator’s main circuit breaker to its ON (or CLOSED) position.
With the preceding steps complete, the generator will start automatically when utility source voltage drops below a preset level. After the unit starts, loads are transferred to the standby power source. Refer to Section 3.4, “Sequence of 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.

3.3.1 12 VDC ACCESSORY OUTLET
The generator is equipped with a 12 VDC accessory outlet in the generator control panel (Figure 3.1). With the generator running or in standby mode, this outlet may be used to temporarily power low power accessories such as a work light, cell phone, radio or any other automotive style accessory. This outlet is capable of delivering a MAXIMUM of 7.5 amps. If the accessory to be used through this circuit demands too much power, the fuse that protects this circuit will melt open and the circuit will not be functional.
This 12 VDC outlet draws power from the gen- erator’s starting battery and extended use of this outlet may drain the battery and the engine may not start. This outlet should NOT be used for battery charging.
