The NEMA 5-20R 120 Volt outlet is overload protected by the 20 Amp push button circuit protector. Figure 2-4. 120 VAC, Duplex Receptacle NEMA 5-20R 120 VAC, 30 Amp Receptacle See Figure 2-5. Use a NEMA L5-30 plug with this receptacle. Connect a suitable 3-wire cord set to the plug and to desired load. The cord set should be rated for 125 Volts AC at 30 Amps (or greater). Use this receptacle to operate 120 Volt AC, 60Hz, single phase loads requiring up to 2500 watts of continuous power at 20.83 Amps. The outlet is protected by a 22 Amp push-to-reset circuit breaker. Figure 2-5. 120 VAC, 30 Amp Receptacle NEMA L5-30R PowerDial™ See Figure 2-6. This controls the ON/OFF functions, choke and fuel valve operation.

• The OFF position (1) stops the engine and shuts off fuel flow.

• The RUN position (2) is for normal opera- tion and to gradually reduce the use of the choke.

• The CHOKE position (3) switches the fuel valve on to start the engine. NOTE: The CHOKE is not required to start a warm engine. Figure 2-6. Switch (example) USB Outlets The 5 VDC, 1 Amp and 2.1 Amp USB outlet allows charging of compatible electronic devices. Generator Status Lights See Figure 2-7.

• Low Oil Level LED (red): Illuminates when oil level is below safe operating level. Engine shuts down (1).

• Overload LED ( red): Indicates system overload (2). During motor starting it is nor- mal for the overload LED to illuminate for a few seconds. If LED stays illuminated and the ready LED turns off, the engine will con- tinue to run without output power. Remove all applied loads and determine if attached devices exceed recommended output power. Check for faulty or shorted connec- tions. To restore electrical output, turn dial OFF to reset. Start engine. If condition was corrected, the red LED will not illuminate and electrical output will be restored. Loads can be applied once the green LED illumi- nates. If the red LED returns, contact an IASD.

• Power LED (green): Indicates output from generator (3) (unless there is a low oil or overload condition). Figure 2-7. Status Indicators

Carbon Monoxide (CO) Detection and Shut-off System (if equipped) The COsense module monitors for the accu-mulation of poisonous CO gas found in engineexhaust when the generator is running. IfCOsense detects increasing levels of CO gas,it automatically shuts off the engine. COsenseonly monitors when the engine is running.Generators are intended to be used outdoors,far from occupied buildings and the exhaustpointed away from personnel and buildings.However, if mis-used and operated in a loca-tion that results in the accumulation of CO, likeindoors or in a partially enclosed area,COsense shuts off the engine, notifies theuser of what has happened and directs the user to read the instruction action label for steps to take. See Figure 2-9. COsense is nota substitute for an indoor carbon monoxidealarm. See Figure 2-8. After a shut-off, a blinking RED light in the COsense badge on the sideof the generator provides notification that thegenerator was shut off due to an accumulatingCO hazard. The RED light will blink for at least five minutes after a CO shut-off. Move the generator to an open, outdoor area and pointthe exhaust away from people and occupiedbuildings. Once relocated to a safe area, the generator can be restarted and the proper electrical connections made to supply electri- cal power. The RED light will stop blinking automatically upon engine re-start. Introducefresh air and ventilate the location where thegenerator had shut down.See Figure 2-8. If a COsense system fault hasoccurred and no longer provides protection,the portable generator is shut off automaticallyand the YELLOW light will blink for at leastfive minutes in the COsense badge to notifythe user of the fault. The COsense modulecan only be diagnosed and repaired by atrained technician at the dealer. The generatorcan be re-started, but may continue to shut- off. COsense will detect the accumulation of Car-bon Monoxide from other fuel burning sourcessuch as engine powered tools or propane heaters used in the area of operation. For example, if another generator is used and the exhaust is pointed at a COsense equipped generator, COsense may initiate a shut-offdue to rising CO levels. This is not an error.Hazardous Carbon Monoxide has beendetected. The user must take action to moveand re-direct these devices to better dissipateCarbon Monoxide far away from personneland occupied buildings.Figure 2-8. Instruction DecalFigure 2-9. Instruction Action Label

!8 Owner’s Manual for Portable Generator Circuit Protectors The AC receptacles are protected by an AC circuit protector. If the generator is overloaded or an external short circuit occurs, the circuit protector will trip. If this occurs, disconnect all electrical loads to determine the cause of the problem before using the generator again. Reduce the load if the circuit protector is tripped. NOTE: Continuous tripping of the circuit pro- tector may cause damage to generator or equipment. Push the button of the protector to reset the circuit protector. Remove Contents from Carton

• In some areas, generators are required to be registered with local utility companies.

• If the generator is used at a construction site, there may be additional regulations which must be observed. Know Generator Limits Overloading a generator can result in damage to the generator and connected electrical devices. Observe the following to prevent overload:

• Add the total wattage of all electrical devices to be connected at one time. This total should NOT be greater than the gener- ator's wattage capacity.

• The rated wattage of lights can be taken from light bulbs. The rated wattage of tools, appliances, and motors can be found on a data label or decal affixed to the device.

• If the appliance, tool, or motor does not give wattage, multiply volts times ampere rating to determine watts (volts x amps = watts).

• Some electric motors, such as induction types, require approximately three times more watts of power for starting than for running. This surge of power lasts only a few seconds when starting such motors. Make sure to allow for high starting wattage when selecting electrical devices to con- nect to the generator:

1. Calculate the watts needed to start the

Section 4 Maintenance and Troubleshooting

Maintenance Regular maintenance will improve perfor- mance and extend engine/equipment life. Generac Power Systems, Inc. recommends that all maintenance work be performed by an Independent Authorized Service Dealer (IASD). Regular maintenance, replacement, or repair of the emissions control devices and systems may be performed by any repair shop or person of the owner’s choosing. To obtain emissions control warranty service free of charge, the work must be performed by an IASD. See the emissions warranty. NOTE: Call 1-888-GENERAC (1-888-436- 3722) with questions about component replacement. Maintenance Schedule Follow maintenance schedule intervals, whichever occurs first according to use. NOTE: Adverse conditions will require more frequent service. NOTE: All required service and adjustments should be completed as detailed in the follow- ing chart. Preventive Maintenance Dirt or debris can cause improper operation and equipment damage. Clean generator daily or before each use. Keep area around and behind muffler free from combustible debris. Inspect all cooling air openings on generator.

• Use a damp cloth to wipe exterior surfaces clean.

• Use a soft bristle brush to loosen caked on dirt, oil, etc.

• Use a vacuum to pick up loose dirt and debris.

• Low pressure air (not to exceed 25 psi) may be used to blow away dirt. Inspect cooling air slots and openings on generator. These openings must be kept clean and unobstructed. NOTE: DO NOT use a garden hose to clean generator. Water can enter engine fuel system and cause problems. If water enters generator through cooling air slots, some water will be retained in voids and crevices of rotor and sta- tor winding insulation. Water and dirt buildup on generator internal windings will decrease insulation resistance of windings.

Proper valve clearance is essential for prolonging the life of the engine. Check valve clearance after the first fifty-hours of operation. Adjust as necessary.

• Intake — 0.125 ± 0.025mm (cold), (0.005" ± 0.001" inches)

• Exhaust — 0.150 ± 0.050 mm (cold), (0.006 ± 0.002 inches) Storage General It is recommended to start and run the genera- tor for 30 minutes, every 30 days. If this is not possible, refer to the following list to prepare unit for storage.

• DO NOT place a storage cover on a hot generator. Allow unit to cool to room tem- perature before storage.

• DO NOT store fuel from one season to another unless properly treated.

• Replace fuel container if rust is present. Rust in fuel will cause fuel system prob- lems.

• Cover unit with a suitable protective, mois- ture resistant cover.

• Store unit in a clean, dry area.

• Always store generator and fuel away from heat and ignition sources. Prepare Fuel System/Engine for Storage Fuel stored over 30 days can go bad and damage fuel system components. Keep fuel fresh, use fuel stabilizer. If fuel stabilizer is added to fuel system, pre- pare and run engine for long term storage. Run engine for 10-15 minutes to circulate sta- bilizer throughout fuel system. Adequately prepared fuel can be stored up to 24 months. NOTE: If fuel has not been treated with fuel stabilizer, it must be drained into an approved container. Run engine until it stops from lack of fuel. Use of fuel stabilizer in fuel storage container is recommended to keep fuel fresh.
