Introduction INTRODUCTION NOTE: Thank you for purchasing this model by Generac Power Systems, Inc. This model is a compact, high performance, air-cooled, engine driven generator designed to supply electrical power to operate electrical loads where no utility power is available or in place of utility due to a power outage. Notes contain additional information important to a procedure and will be found within the regular text body of this manual.
Safety Rules SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted near the unit's installation site. Safety should be stressed to all operators and potential operators of this equipment.
Safety Rules STANDARDS INDEX 1. 2. 3. 4. 5. National Fire Protection Association (NFPA) 70: The NATIONAL ELECTRIC CODE (NEC) available from www.nfpa.org National Fire Protection Association (NFPA) 5000: BUILDING CONSTRUCTION AND SAFETY CODE available from www.nfpa.org International Building Code available from www.iccsafe.org Agricultural Wiring Handbook available from www.rerc.org , Rural Electricity Resource Council P.O.

General Information 1.1 UNPACKING 1.2 • Set the palleted carton on a rigid flat surface. • Remove staples along bottom of carton that fasten carton to pallet. Open carton from top. • Remove all packaging material. ASSEMBLY The generator requires some assembly prior to using it. If problems arise when assembling the generator, please call the Generator Helpline at 1-888-436-3722. 1.2.1 • Remove separate accessory box. • Lift carton off the generator.
General Information Figure 2 - Handle Assembly 1.2.3 BATTERY CONNECTION • The battery shipped with the generator has been provided fully charged. Caution must be taken when connecting the battery. NOTE: Figure 3 - Battery Connections Negative Cable Positive Cable A battery may lose some of it’s charge when not in use for prolonged periods of time. 1. 2. 3. 4. 5. Cut the tie wrap cable holding the RED and BLACK battery cables to the stator.
Operation 2.1 KNOW THE GENERATOR Read the Owner’s Manual and Safety Rules before operating this generator. Compare the generator to Figures 4 through 7 to become familiarized with the locations of various controls and adjustments. Save this manual for future reference. 1. 12 Volt DC, 10 Amp Receptacle – This receptacle allows the capability to recharge a 12 volt DC storage battery with provided battery charge cables. 2.
Operation Figure 7 - Oil Fill Figure 8 – Hourmeter 0000.0 15 HOUR GLASS GRAPHIC RESET BUTTON (IF EQUIPPED) 2.3 CORD SETS AND CONNECTION PLUGS 2.3.1 120 VAC, 20 AMP, DUPLEX RECEPTACLE The Hourmeter tracks hours of operation for scheduled maintenance (see chart). This is a 120 Volt outlet protected against overload by a 20 Amp pushto-reset circuit breaker (Figure 9). Use each socket to power 120 Volt AC, single phase, 60 Hz electrical loads requiring up to a combined 2400 watts (2.
Operation 2.3.2 120 VAC, 20 AMP, GFCI RECEPTACLE 2.3.3 120 VAC, 30 AMP RECEPTACLE This unit is equipped with a ground fault circuit interrupter (GFCI). This device meets applicable federal, state and local codes (Figure 10). Use a NEMA L5-30 plug with this receptacle. Connect a 3-wire cord set rated for 125 Volts AC at 30 Amps (or greater) to the plug (Figure 11). A GFCI receptacle is different from conventional receptacles.
Operation Figure 13 - 12 Volt DC, 10 Amp Receptacle This exhaust system must be properly maintained. Do nothing that might render the exhaust system unsafe or in noncompliance with any local codes and/or standards. Always use a battery operated carbon monoxide alarm indoors, installed according to the manufacturers instructions. 2.3.6 120/240 VAC, 50 AMP RECEPTACLE Use a NEMA 14-50 plug with this receptacle. Connect a 4-wire cord set rated for 250 Volts AC at 50 Amps to the plug (Figure 14).
Operation Figure 15 - Grounding the Generator Generator Ground Lug 2.4.3 CONNECTING ELECTRICAL LOADS DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT connect 3-phase loads to the generator. DO NOT connect 50 Hz loads to the generator. • Let engine stabilize and warm up for a few minutes after starting. • Plug in and turn on the desired 120 or 240 Volt AC, single phase, 60 Hz electrical loads. • Add up the rated watts (or amps) of all loads to be connected at one time.
Operation 2.7 BEFORE STARTING THE GENERATOR . Prior to operating the generator, engine oil and gasoline will need to be added, as follows: 2.7.1 2. 3. ADDING ENGINE OIL All oil should meet minimum American Petroleum Institute (API) Service Class SJ, SL or better. Use no special additives. Select the oil's viscosity grade according to the expected operating temperature (also see chart). 4. To reduce lead and carbon deposits use high quality UNLEADED gasoline with the generator engine.
Operation Figure 17 - Fuel Shut-off Valve 4. Figure 19 - Full Choke Position Locate the Idle Control ON/OFF switch on the control panel and set it to the “OFF” position (Figure 18). Figure 18 - Idle Control Switch 2.9 1. 2. 3. 4. 5. STOPPING THE ENGINE Shut off all loads, then unplug the electrical loads from generator panel receptacles. Never start or stop the engine with electrical devices plugged in and turned on. Turn “Off” the Idle Control switch (if on).
Maintenance 2.12.2 SENSING LOW OIL PRESSURE If the system senses low oil pressure during operation, the engine shuts down. 2.12.3 RESTARTING If trying to restart the engine within 10 seconds after it shuts down, the engine may NOT start. The system needs five (5) to 10 seconds to reset. If the engine is restarted after such a shutdown and the low oil pressure has not been corrected, the engine will run for about 10 seconds as described above and then stop. 2.13 CHARGING A BATTERY while recharging.
Maintenance 3.3.2 ENGINE SPECIFICATIONS Rated Horsepower @ 3600 RPM 30 Displacement 992cc Spark Plug Type Champion RC14YC or Equivalent Spark Plug Part No. 0E7585A Spark Plug Gap 0.040 inch or (1.01 mm) Gasoline Capacity 16 U.S. gallons Oil Type Summer – SAE 30, Winter – 5W-30 Synthetic or 10W-30 Oil Capacity w/ Filter Change = 1.7 Qts., w/o Filter Change = 1.4 Qts. Oil Filter Part No. 070185E NOTE: Once a year, replace the spark plug and replace the air filter.
Maintenance 3.4.5 CHANGING THE OIL AND OIL FILTER Change the oil and filter after the first 30 hours of operation. Change the oil every 100 hours thereafter. If running this unit under dirty or dusty conditions, or in extremely hot weather, change the oil more often. Use the following instructions to change the oil after the engine cools down: 1. 2. 3. 4. 5. 6. 7. 8. Clean area around oil drain hose and plug.
Maintenance Figure 22 - Spark Arrestor 3.7 ADJUSTING VALVE CLEARANCE After the first 50 hours of operation, check the valve clearance in the engine and adjust if necessary. Important: If feeling uncomfortable about doing this procedure or the proper tools are not available, please take the generator to the nearest service center to have the valve clearance adjusted. This is a very important step to insure longest life for the engine.
Maintenance 3.9 LONG TERM STORAGE It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel hose or tank during storage. Also, experience indicates that alcohol-blended fuels (called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.
Troubleshooting 4.1 TROUBLESHOOTING GUIDE PROBLEM CAUSE CORRECTION Engine is running, but no AC output is available. 1. Circuit breaker is open. 2. Poor connection or defective cord set. 3. Connected device is bad. 4. Fault in generator. 5. 120V GFCI tripped (no light). 1. Reset circuit breaker. 2. Check and repair. 3. Connect another device that is in good condition. 4. Contact Authorized Service Facility. 5. Reset 120V GFCI push button (light is on).
