Product Specifications

Outlets

120 VAC, Duplex Outlet

• The 120 volt outlet is overload protected by the 20 amp push button circuit protecto

120 VAC, 30 Amp Outlet

• Use a NEMA L5-30R plug with this outlet. 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 outlet to operate 120 volts AC, 60 Hz, singlephase loads requiring up to 3300 Watts, 27.5 amps starting power and 2500 Watts of continuous power at 20.83 amps. The outlet is protected by a 20 amp push-to-reset circuit breaker.

Start Dial (OFF/RUN/CHOKE)

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 operation and to gradually reduce the use of the choke.
• The CHOKE position 3 switches the fuel valve on to start the engine.

NOTE: CHOKE is not required to start a warm engine.

USB Outlets: The 1A/2.1A, 5 VDC USB outlets allow charging of compatible electronic devices.

Generator Status Lights

• Overload LED (red): Indicates system overload 2 . During motor starting, it is normal for the overload LED to illuminate for a few seconds. If LED stays illuminated and the ready LED turns off, the engine will continue to run without output power. Remove all applied loads and determine if attached devices exceed recommended output power. Inspect for faulty or shorted connections. To restore electrical output, rotate Start 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 illuminates. If the red LED returns, contact a Service Dealer.
• Low Oil Level LED (yellow): Illuminates when oil level is below safe operating level. Engine shuts down 1 .
• Power LED (green): Indicates output from generator 3 (unless there is a low oil or overload condition).

Circuit Breakers

• The AC receptacles are protected by an AC circuit breaker. If the generator is overloaded or an external short circuit occurs, the circuit breaker 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 breaker is tripped.
• NOTE: Continuous tripping of the circuit breaker may cause damage to generator or equipment.
• Push the button of the breaker to reset circuit breaker.

CO Detection

Carbon Monoxide (CO) Detection and Shutoff System (if equipped)

• DANGER: Asphyxiation. Running engines produce carbon monoxide, a colorless, odorless, poisonous gas. Carbon monoxide, if not avoided, will result in death or serious injury. (000103)
• WARNING: Asphyxiation. Always use a battery operated carbon monoxide alarm indoors and installed according to the manufacturer’s instructions. Failure to do so could result in death or serious injury. (000178a)
• The CO Detection module monitors for the accumulation of poisonous CO gas found in engine exhaust when the generator is running. CO Detection automatically shuts off the engine if it detects increasing levels of CO gas. CO Detection only monitors when the engine is running. Generators are intended to be used outdoors, far from occupied buildings, with the exhaust pointed away from personnel and buildings. However, if misused and operated in a location which results in the accumulation of CO—like indoors or in a partially enclosed area—CO Detection shuts off the engine, notifies the user of what has happened, and directs the user to read the instruction action label for steps to take (Fig. H). CO Detection is not a substitute for an indoor carbon monoxide alarm.
• As the user approaches the generator to investigate a shutoff, a blinking RED light in the CO Detection badge on the side of the generator notifies the user the generator was shutoff due to an accumulating CO hazard. The RED light will blink for at least five minutes after a CO shutoff. Move the generator to an open, outdoor area and point the exhaust away from people and occupied buildings. Once relocated to a safe area, the generator can be restarted and the correct electrical connections made to supply electrical power. The RED light will stop blinking automatically upon engine start. Introduce fresh air and ventilate the location where the generator had shut down.
• If a CO Detection system fault has occurred and no longer provides protection, the portable generator shuts off automatically, and the YELLOW light in the CO Detection badge will blink for at least five minutes to notify the user of the fault. The CO Detection module can only be diagnosed and repaired by a trained technician at the dealer. The generator can be started, but may continue to shutoff.
• CO Detection will detect the accumulation of CO from other fuel burning sources such 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 CO Detection equipped generator, CO Detection may initiate a shutoff due to rising CO levels. This is not an error as hazardous CO has been detected. The user must take action to move and redirect these devices to better dissipate CO far away from personnel and occupied buildings.
  • See Fig. G. IF red LED A is flashing, a CO Shutoff has occurred.
  • IF yellow LED B is flashing, a CO System Fault has occurred.

Fuel

• DANGER: Explosion and Fire. Fuel and vapors are extremely flammable and explosive. Add fuel in a well ventilated area. Keep fire and spark away. Failure to do so will result in death or serious injury. (000105)
• DANGER: Explosion and Fire. Do not fill fuel tank past full line. Allow for fuel expansion. Overfilling may cause fuel to spill onto engine causing fire or explosion, which will result in death or serious injury. (000214)
• Fuel requirements are as follows:
  • Clean, fresh, unleaded gasoline.
  • Minimum rating of 87 octane/87 AKI (91 RON).
  • Up to 10% ethanol (gasohol) is acceptable (where available; non-ethanol fuel is recommended).
  • DO NOT use E85.
  • DO NOT use a gas oil mix.
  • DO NOT modify engine to run on alternate fuels. Stabi - lize fuel prior to storage.
    1. Verify unit is OFF and cooled entirely prior to fueling
    2. Place unit on level ground in a well ventilated area.
    3. Clean area around fuel cap.
    4. Turn fuel cap slowly to remove
    5. Slowly add recommended fuel. Do not overfill.
    6. Install fuel cap.
• NOTE: Allow spilled fuel to evaporate before starting unit.
• IMPORTANT NOTE: It is important to prevent gum depos - its from forming in fuel system parts such as the carbu - retor, fuel hose or tank during storage. 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. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. See the Storage section. Never use engine or carburetor cleaner products in the fuel tank as permanent damage may occu

• WARNING: Asphyxiation. Always use a battery operated carbon monoxide alarm indoors and installed according to the manufacturer’s instructions. Failure to do so could result in death or serious injury. (000178a)
• WARNING: Risk of Fire. Hot surfaces could ignite combustibles, resulting in fire. Fire could result in death or serious injury. (000110)
• WARNING: Hot surfaces. When operating machine, do not touch hot surfaces. Keep machine away from combustibles during use. Hot surfaces could result in severe burns or fire. (000108)
• CAUTION: Equipment and property damage. Disconnect electrical loads prior to starting or stopping unit. Failure to do so could result in equipment and property damage. (000136)

Grounding Generator

• When In Use See Fig. K. The generator is equipped with an equipment ground connecting the generator frame and the ground terminals on the AC output outlets (see NEC 250.34) A . This allows the generator to be used as a portable generator without grounding the frame of the generator as specified in NEC 250.34.
  • Neutral Floating

• The generator (stator winding) is isolated from the frame and from the AC outlet ground pin. Electrical devices requiring a grounded outlet pin connection will not function if the outlet ground pin is not functional.

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 generator'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. Allow for higher starting wattage when selecting electrical devices to connect to the generator:
  1. Calculate wattage needed to start the largest motor.
  2. Add the running Watts of all other connected loads to that figure.

The Wattage Reference Guide is provided to assist in determining how many items the generator can operate at one time.

NOTE: All figures are approximate. See data label on appliance for wattage requirements.

Wattage Reference Guide
