  • Page 5: Safety Instructions

    SAFETY INSTRUCTIONS IMPORTANT SAFETY INFORMATION Honda generators are designed for use with electrical equipment that has suitable power requirements. Other uses can result in injury to the operator or damage to the generator and other property. Most injuries or property damage can be prevented if you follow all instructions in this manual and on the generator.
  • Page 6 Carbon Monoxide Hazards Exhaust contains poisonous carbon monoxide, a colorless, odorless gas. Breathing exhaust can cause loss of consciousness and may lead to death. If you run the generator in an area that is confined, or even partially enclosed area, the air you breathe could contain dangerous amount of exhaust gas.
  • Page 7 Fire and Burn Hazards Do not use the generator in areas with a high risk of fire. When installed in ventilated rooms, additional requirements for fire and explosion protection shall be observed. The exhaust system gets hot enough to ignite some materials. Keep the generator at least 1 meter (3 feet) away from buildings and other equipment during operation.
  • Page 8 Disposal To protect the environment, do not dispose of the used generator, battery, engine oil, etc. carelessly by leaving them in the waste. Observe the local laws or regulations or consult your authorized Honda generator dealer to dispose of these parts. Please dispose of used motor oil in a manner that is compatible with the environment.

  • Page 9: Safety Label Locations

    SAFETY LABEL LOCATIONS These labels warn you of potential hazards that can cause serious injury. Read the labels and safety notes and precautions described in this manual carefully. If a label comes off or becomes hard to read, contact your Honda dealer for a replacement.
  • Page 10 Honda generator is designed to give safe and dependable service if operated according to instructions. Read and understand the Owner’s Manual before operating the generator. Failure to do so could result in personal injury or equipment damage. Exhaust contains poisonous carbon monoxide, a colorless, odorless gas.
  • Page 11 Stop the engine before refueling. Gasoline is extremely flammable and explosive under certain conditions. Refuel in a well ventilated area with the engine stopped. Keep away from cigarette, smoke and sparks when refueling the generator. Always refuel in a well ventilated location. Wipe up spilled gasoline at once.

  • Page 17 Eco Throttle ECO: Engine speed is kept at idle automatically when the electrical appliance is disconnected and it returns to the proper speed by the electrical load when electrical appliance is connected. This position is recommended to minimize the fuel consumption while in operation. Eco Throttle system does not operate sufficiently if the electrical appliance requires the momentary electric power.

  • Page 18: Pre-Operation Check

    PRE-OPERATION CHECK Be sure to check the generator on a level surface with the engine stopped. Check the engine oil level. Using non detergent oil or 2-stroke engine oil could shorten the engine’s service life. Recommended oil Use high-detergent, premium quality 4-stroke engine oil, certified to meet or exceed U.S.
  • Page 19 Loosen the cover screw and remove the left side maintenance cover. Remove the oil filler cap, and wipe the dipstick with a clean rag. Check the oil level by inserting the dipstick in the filler hole without screwing it in. If the oil level is below the end of the dipstick, refill with recommended oil up to the top of the oil filler neck.
  • Page 20 Check the fuel level. If the fuel level is low, refuel the fuel tank until the level as specified. After refueling, tighten the fuel filler cap securely. Use automotive unleaded gasoline with a Research Octane Number of 91 or higher (a Pump Octane Number of 86 or higher). Never use stale or contaminated gasoline or an oil/gasoline mixture.
  • Page 21 Gasoline spoils very quickly depending on factors such as light exposure, temperature and time. In worst cases, gasoline can be contaminated within 30 days. Using contaminated gasoline can seriously damage the engine (carburetor clogged, valve stuck). Such damage due to spoiled fuel is disallowed from coverage by the warranty.
  • Page 22 Check the air cleaner. Check the air cleaner element to be sure it is clean and in good condition. Loosen the cover screw and remove the left side maintenance cover. Press the latch tab on the top of the air cleaner body, remove the air cleaner cover, check the element.

  • Page 23: Starting The Engine

    STARTING THE ENGINE Before starting the engine disconnect any load from the AC receptacle. Turn the fuel cap lever fully clockwise to the ON position. Turn the fuel cap vent lever to the OFF position when transporting the generator. FUEL CAP VENT LEVER Turn the engine switch to the ON position.
  • Page 24 Move the choke lever to the CLOSED position. Do not use the choke when the engine is warm or the air temperature is high. CHOKE LEVER CLOSED CLOSED Pull the starter grip lightly until you feel resistance, then pull the starter grip briskly toward in the direction of the arrow as shown below.
  • Page 25 Move the choke lever to the OPEN position as the engine warms up. CHOKE LEVER OPEN If the engine stops and will not restart, check the engine oil level (see page ) before troubleshooting in other areas.

  • Page 26: Carburetor Modification For High Altitude Operation

    Carburetor Modification for High Altitude Operation At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting. Operation at an altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions.

  • Page 27: Generator Use

    GENERATOR USE Be sure to ground the generator when the connected equipment is grounded. Do not connect to a building’s electrical system unless an isolation switch has been installed by a qualified electrician. Connections for standby power to a building’s electrical system must be made by a qualified electrician and must comply with all applicable laws and electrical codes.

  • Page 32 Please read the item ‘‘GENERATOR USE’’ before connecting any equipment to be used. Use only a Honda approved receptacle box for parallel operation (optional) when connecting two EU20i generators for parallel operation. Make sure that the electrical rating of the tool or appliance does not exceed that of the generator.
  • Page 33 Never connect the different generator models and types. Never connect a cable other than the receptacle box for parallel operation. Connect and remove the receptacle box for parallel operation with the engine stopped. For single operation, the receptacle box for parallel operation must be removed.
  • Page 34 Connect the cable connectors and ground terminals of the receptacle box for parallel operation to the generators and secure the cord clamp to handle. Place two generators at least 1 meter (3 feet) away from each other during parallel operation. Route the wire through the handle and clamp it to the handle using the band.
