Section 1 — General Information 15 kW Generator 1.10.2 TRANSFER SWITCH 1.10.2.1 15 kW Units Transfer switches for use with this generator are sold separately and can be purchased from dealers. • Install any transfer switch in accordance with the instructions supplied with the transfer switch. • Failure to utilize a the manufacturer’s transfer switch with this generator will void the warranty. 1.
Section 2 — Post Installation Start-up and Adjustments 15 kW Generator The following procedures are to be observed: • Wear full eye protection and protective clothing; • Where electrolyte contacts the skin, wash it off immediately with water; • Where electrolyte contacts the eyes, immediately flush thoroughly with water and seek medical attention; and • Spilled electrolyte is to be washed down with an acid neutralizing agent.
Section 2 — Post Installation Start-up and Adjustments 15 kW Generator DANGER with caution! Generator power voltage Proceed is now supplied to the transfer switch. Contact with live transfer switch parts will result in dangerous and possibly fatal electrical shock. 11. Connect an accurate AC voltmeter and a frequency meter across transfer switch terminal lugs E1 and E2. Voltage should be 242-252 volts; frequency should read about 61-63 Hertz. 12.
Section 2 — Post Installation Start-up and Adjustments 15 kW Generator With the generator running and loads powered by generator AC output, turn ON the utility power supply to the transfer switch. The following should occur: • After about six seconds, the switch should transfer loads back to the utility power source. • About one minute after retransfer, the engine should shut down. 2.
Section 3 — Operation 15 kW Generator 2.7 ENGINE GOVERNOR ADJUSTMENT If both AC frequency and voltage are correspondingly high or low, adjust the engine governor as follows: 2.7.1 15 KW UNITS 1. Loosen governor clamp bolt (See Figure 2.3). Figure 2.3 — V-twin Engine Governor Adjustment 2.8 VOLTAGE REGULATOR ADJUSTMENT With the frequency between 62-63.5 Hertz, slowly turn the slotted potentiometer (Figure 2.5) until line voltage reads 244-252 volts.
Section 3 — Operation 15 kW Generator 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”.
Section 3 — Operation 15 kW Generator 3.3.2 120 VAC GFCI OUTLET The generator is equipped with an external 15 amp, 120 volt, GFCI convenience outlet that is located in the right rear of the generator enclosure. When the generator is running, in the absence of utility power, this outlet may be used to power items outside a home such as lights or power tools. This outlet may also be used when utility power is present by running the generator in manual mode.
Section 3 — Operation 15 kW Generator 5. To crank and start the engine, set the AUTO/OFF/ MANUAL switch to MANUAL. 6. Let the engine stabilize and warm up for a few minutes. 7. Set the generator’s main circuit breaker to its ON (or CLOSED) position. The standby power source now powers the loads. 3.5.2 TRANSFER BACK TO UTILITY POWER SOURCE When utility power has been restored, transfer back to that source and shut down the generator. This can be accomplished as follows: 1.
Section 4 — Maintenance 15 kW Generator 3.7.3 4.2 OVERCRANK This feature prevents the generator from damaging itself when it continually attempts to start and another problem, such as no fuel supply, prevents it from starting. The unit will crank and rest for a preset time limit. Then, it will stop cranking, and the LED will light indicating an overcrank failure. The AUTO/OFF/ MANUAL switch will need to be set to OFF and then back to AUTO to reset the generator control board.
Section 4 — Maintenance 15 kW Generator 4.5 attempt to crank or start the engine before Any it has been properly serviced with the recommended oil may result in an engine failure. 4.3.2 OIL CHANGE PROCEDURE To change the oil, proceed as follows: 1. Run the engine until it is thoroughly warmed up then shut OFF the engine. 2. Immediately after the engine shuts OFF, pull the oil drain hose (Figure 4.3) free of its retaining clip. Remove the cap from the hose and drain the oil into a suitable container.
Section 4 — Maintenance 15 kW Generator Figure 4.5 – Setting the Spark Plug Gap SET PLUG GAP AT 0.050 mm/0.020 inch 4.7 BATTERY MAINTENANCE • Wear full eye protection and protective clothing; • Where electrolyte contacts the skin, wash it off immediately with water; • Where electrolyte contacts the eyes, immediately flush thoroughly with water and seek medical attention; and • Spilled electrolyte is to be washed down with an acid neutralizing agent.
Section 4 — Maintenance 15 kW Generator • Make sure the piston is at Top Dead Center (TDC) of its compression stroke (both valves closed). To get the piston at TDC, remove the intake screen at the front of the engine to gain access to the flywheel nut. Use a large socket and socket wrench to rotate the nut and hence the engine. While watching the piston through the spark plug hole. The piston should move up and down. The piston is at TDC when it is up as high as it can go. • Loosen the rocker jam nut.
Section 4 — Maintenance 15 kW Generator 4.12 OUT OF SERVICE PROCEDURE 4.12.2 RETURN TO SERVICE 4.12.1 REMOVAL FROM SERVICE To return the unit to service after storage, proceed as follows: If the generator cannot be exercised every seven days, and will be out of service longer than 90 days, prepare the generator for storage as follows: 1. Start the engine and let it warm up. 2. Close the fuel shutoff valve in the fuel supply line and allow the unit to shut down. 3.
