INTRODUCTION 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. READ THIS MANUAL THOROUGHLY We also strongly recommend instructing other users to properly start and operate the unit. This prepares them if they need to operate the equipment in an emergency.
IMPORTANT SAFETY INSTRUCTIONS THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted near the unit's SAVE installation site. Safety should be stressed to all operators and potential operators of this equipment. • Never start or stop the unit with electrical loads connected to receptacles AND with connected devices turned ON. Start the engine and let it stabilize before connecting electrical loads.
IMPORTANT SAFETY INSTRUCTIONS ELECTRICAL HAZARDS EXPLOSION HAZARDS • All generators covered by this manual produce dangerous electrical voltages and can cause fatal electrical shock. Utility power delivers extremely high and dangerous voltages as does the generator when it is in operation. Avoid contact with bare wires, terminals, connections, etc., while the unit is running. Ensure all appropriate covers, guards and barriers are in place before operating the generator.
Section 1 – General Information 1.1 UNPACKING 1.2 ASSEMBLY • 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. • Remove separate accessory box. • Lift carton off the generator. • Remove generator from shipping pallet by removing bolts through the shipping brackets (Figure 1). The generator requires some assembly prior to using it.
Section 1 - 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. • Cut the tie wrap cable holding the RED and BLACK battery cables to the stator.
Section 2 – Operation Figure 5 - Generator Controls 2.1 KNOW THE GENERATOR Read the Owner’s Manual and Safety Rules before operating this generator. Compare the generator to Figures 4 through 6 to become familiarized with the locations of various controls and adjustments. Save this manual for future reference. 11 7 Figure 4 - Control Panel 12 15 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.
Section 2 – Operation 2.2 CORD SETS AND CONNECTION PLUGS Figure 8 - 120 VAC, 20 Amp GFCI Receptacle 2.2.1 120 VAC, 20 AMP, DUPLEX RECEPTACLE This is a 120 Volt outlet protected against overload by a 20 Amp push-to-reset circuit breaker (Figure 7). Use each socket to power 120 Volt AC, single phase, 60 Hz electrical loads requiring up to a combined 2400 watts (2.4 kW) or 20 Amps of current. Use only high quality, well-insulated, 3-wire grounded cord sets rated for 125 Volts at 20 Amps (or greater).
Section 2 – Operation Use this receptacle to operate 120 Volt AC, 60 Hz, single phase loads requiring up to 3600 watts (3.6 kW) of power at 30 Amps. The outlet is protected by a 30 Amp push-to-reset circuit breaker. Figure 12 - 120/240 VAC, 50 Amp Receptacle 2.2.4 120/240 VAC, 30 AMP RECEPTACLE Use a NEMA L14-30 plug with this receptacle. Connect a suitable 4wire grounded cord set to the plug and to the desired load. The cord set should be rated for 250 Volts AC at 30 Amps (or greater) (Figure 10).
Section 2 – Operation Proper grounding of the generator will help prevent electrical shock in the event of a ground fault condition in the generator or in connected electrical devices. Proper grounding also helps dissipate static electricity, which often builds up in ungrounded devices. 2.3.2 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.
Section 2 – Operation 2.6 BEFORE STARTING THE GENERATOR 2.6.2 ADDING GASOLINE Prior to operating the generator, engine oil and gasoline will need to be added, as follows: fill fuel tank indoors. Never fill fuel tank Never when engine is running or hot. DO NOT light a 2.6.1 ADDING ENGINE OIL cigarette or smoke when filling the fuel tank. NOTE: When adding oil to the engine crankcase in the future, use only high quality detergent oil rated with API service classification SG, SH or SL.
Section 2 – Operation 2.7 TO START THE ENGINE • Move engine CHOKE knob outward to “Full Choke” position (Figure 17). Figure 17 - Full Choke Position Never start or stop engine with electrical devices plugged into the receptacles AND devices turned on. • Unplug all electrical loads from the unit's receptacles before starting the engine. • Make sure the unit is in a level position. • Open the fuel shut-off valve (Figure 15).
Section 2 – Operation 2.9 AUTOMATIC IDLE CONTROL This feature is designed to greatly improve fuel economy. When this switch is turned “On,” the engine will only run at its normal fast governed engine speed when electrical load is connected. When the load is removed, the engine will run at a reduced speed of 2100 RPM. With the switch “Off,” the engine runs at the normal fast engine speed all the time. Always have the switch OFF when starting and stopping the engine. 2.
Section 3 — Maintenance 3.2.2 ENGINE SPECIFICATIONS 3.1 MAINTENANCE SCHEDULE Follow the calendar intervals. More frequent service is required when operating in adverse conditions noted below. Maintenance Daily Check Oil Level Every Season Rated Horsepower @ 3600 RPM 30 Displacement 992cc Spark Plug Type Champion RC14YC or Equivalent Spark Plug Gap 0.040 inch or (1.01 mm) Service Air Pre-Cleaner ** Gasoline Capacity 16 U.S.
Section 3 — Maintenance NOTE: DO NOT use a garden hose to clean generator. Water can enter the engine fuel system and cause problems. In addition, if water enters the generator through cooling air slots, some water will be retained in voids and crevices of the rotor and stator winding insulation. Water and dirt buildup on the generator internal windings will eventually decrease the insulation resistance of these windings. 3.3.
Section 3 — Maintenance To clean or replace foam pre-cleaner: 3.6 ADJUSTING VALVE CLEARANCE • Remove air cleaner cover, then foam pre-filter. • Wash pre-cleaner in soapy water. Squeeze pre-filter dry in clean cloth (DO NOT TWIST). • Clean air cleaner cover before re-installing it. To clean or replace paper air filter: After the first 50 hours of operation, check the valve clearance in the engine and adjust if necessary.
Section 3 — Maintenance When valve clearance is correct, hold the pivot ball stud in place with the allen wrench and tighten the rocker arm jam nut. Tighten the jam nut to 174 in/lbs. torque. After tightening the jam nut, recheck valve clearance to make sure it did not change. • Install new valve cover gasket. • Re-attach the valve cover. NOTE: Start all four screws before tightening or it will not be possible to get all the screws in place. Make sure the valve cover gasket is in place.
Section 4 — Troubleshooting 4.1 TROUBLESHOOTING GUIDE PROBLEM CAUSE CORRECTION Engine is running, but no AC output is available. 1. 2. 3. 4. Circuit breaker is open. Poor connection or defective cord set. Connected device is bad. Fault in generator. 1. 2. 3. 4. Reset circuit breaker. Check and repair. Connect another device that is in good condition. Contact Authorized Service Facility. Engine runs good but bogs down when loads are connected. 1. 2. 3. 4. Short circuit in a connected load.
