Connection Plugs

120 VAC, 20 Amp, Duplex Receptacle
The 120 Volt outlet is overload protected by a 20 Amp push-to-reset circuit breaker. See Figure 2-3. Each receptacle will power 120 Volt AC, single phase, 60 Hz electrical loads requiring up to 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).

120 VAC, 30 Amp Receptacle
Use a NEMA L5-30 plug with this receptacle (rotate to lock/unlock). 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). See Figure 2-4. Use this receptacle to operate 120 Volt AC, 60Hz, single phase loads requiring up to 3000 watts (3.0kW) of power at 25 Amps. The outlet is protected by a 25 Amp circuit breaker.

ON/O FF/CHOKE Switch
This controls the ON/OFF functions, choke and fuel valve operation. See Figure 2-5.

• The OFF position (1) stops the engine and shuts off fuel flow.
• The ON position (2) is for normal opera-tion and to gradually reduce the use of the choke.

Economy Switch
The economy switch has 2 modes of opera-tion:

• ON: The quietest mode and best when running appliances or equipment that are resistive loads (non-motor starting), (example: TV, video game, light, radio).
• OFF : Best when running a both inductive (motor-starting loads) and resistive (non-motor starting loads), especially when these loads are turning on and off (example: RV, air conditioner, hairdryer).

AC Reset
The AC receptacle is protected by inverter module.
If the generator is overloaded or an external short circuit occurs, the inverter module will stop working and there will be no voltage output from the generator.

If this occurs, disconnect all electrical loads to determine the cause of the problem before using the generator again.
Afterwards, press the AC RESET button, the inverter reverts to normal working condition, and the output voltage of the generator returns to normal.

DC Reset
The DC Receptacle is protected by DC reset(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 protector may cause damage to generator or equipment.
Push DC rest button to reset the circuit protector.

10. Replace side cover and screws.

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.
• Explosion and Fire. Do not overfill fuel tank. Fill to 1/2 inch from top of tank to allow for fuel expansion.
  Overfilling may cause fuel to spill onto engine causing fire or explosion, which will result in death or serious injury.

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.

• DO NOT use E85.

• DO NOT use a gas oil mix.

• DO NOT modify engine to run on alternate fuels. Stabilize 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.
     WARNING
     Explosion and Fire. Verify fuel cap vent is set to ON for operation, and OFF for transportation and storage. Failure to do so could result in poor unit performance, death, or serious injury.

  3. Clean area around fuel cap and turn vent on fuel cap to ON. See Figure 2-9.

  4. Turn cap slowly to remove.

  5. Slowly add recommended fuel. Do not overfill.

  6. Install fuel cap.

  7. Turn vent on fuel cap to OFF for transportation and storage to avoid fuel spills.

NOTE: Allow spilled fuel to evaporate before starting unit.

IMPORTANT NOTE: It is important to prevent gum deposits from forming in fuel system parts such as the carburetor, fuel hose or tank during storage. Alcoholblended 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 occur.

OPERATION

Before Starting Engine

1. Verify engine oil level is correct.
2. Verify fuel level is correct.
3. Verify unit is secure on level ground, with proper clearance and is in a well ventilated area.

Prepare Generator for Use

DANGER

• Asphyxiation. Running engines produce carbon monoxide, a colorless, odorless, poisonous gas. Carbon monoxide, if not avoided, will result in death or serious injury.
• Asphyxiation. The exhaust system must be properly maintained. Do not alter or modify the exhaust system as to render it unsafe or make it noncompliant with local codes and/or standards. Failure to do so will result in death or serious injury.

WARNING

• Risk of fire. Do not use generator without spark arrestor installed. Failure to do so could result in death or serious injury.
• 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.
• Risk of Fire. Hot surfaces could ignite combustibles, resulting in fire. Fire could result in death or serious injury.
• 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.

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.

Grounding the Generator When In Use
The generator is equipped with an equipment ground connecting the generator frame and the ground terminals on the AC output recep- tacles. This allows the generator to be used as a portable without grounding the frame of the generator. See Figure 3-1.

The generator (stator winding) is isolated from the frame and from the AC receptacle ground pin. Electrical devices that require a grounded receptacle pin connection will not function if the receptacle 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 up 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 about 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 select-ing electrical devices to connect to the gen-erator:

  1. Figure the watts needed to start the largest motor.
  2. Add to that figure the running watts of all other connected loads.

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.

Storage

General

DANGER
Explosion and Fire. Fuel and vapors are extremely flammable and explosive. Store fuel in a well ventilated area. Keep fire and spark away. Failure to do so will result in death or serious injury.

WARNING
Risk of Fire. Verify machine has properly cooled before installing cover and storing machine. Hot surfaces could result in fire.

It is recommended to start and run the generator 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 problems.
• Cover unit with a suitable protective, moisture-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, prepare and run engine for long- term storage. Run engine for 10-15 minutes to circulate stabilizer 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.
