Connection Plugs
AC Socket
The AC outlet is overload protected by the invertor. Each socket will power single phase, Volt AC, See Figure 2-3.

OFF / ON / CHOKE Switch
This controls the ON/OFF functions, choke and fuel valve operation. See Figure 2-4.

• The OFF position (1) stops the engine and shuts off fuel flow.
• The ON 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: The CHOKE is not required to start a warm engine.

Economy Switch
The economy switch has 2 modes of operation:

• 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 (nonmotor starting loads), especially when these loads are turning on and off (example: RV, air conditioner, hairdryer).
  Generator Status Lights
  See Figure 2-5.

• Overload LED (orange): 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. Check for faulty or shorted connections. To restore electrical output, turn dial OFF to reset. Start engine. If condition was corrected, the orange LED will not illuminate and electrical output will be restored.
  Loads can be applied once the green LED illuminates. If the orange LED returns, con- tact an IASD (Independent Authorized Service Dealer).

• Low Oil Level LED (red): 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).

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.

7. Remove dipstick and verify oil level is within safe operating range.
   NOTE: Verify oil level often during filling process to ensure overfilling does not occur.

8. Install oil fill cap/dipstick and hand-tighten.

9. Replace side cover and screws.

Fuel

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.

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 pre- vent 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.

Section 3 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

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.

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.

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.

• Neutral Floating

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 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 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 selecting electrical devices to connect to the generator:

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.
Wattage Reference Guide

• Allow 3 times the listed watts for starting these devices.

Transporting/Tipping of the Unit
Do not store or transport the unit at an angle greater than 15 degrees.

2. Firmly grasp recoil handle and pull slowly until increased resistance is felt. Pull rapidly up and away.

Low Oil Level Shutdown System
The engine is equipped with a low oil level sensor that shuts down the engine automatically when the oil level drops below a specified level to prevent engine damage. See Figure 3-3 (B). The engine will not run until the oil has been filled to the proper level.
If the engine shuts down and there is sufficient fuel, check engine oil level.
Parallel Operation
For output power up to 3420W, two inverters can operate in parallel using Parallel Kit (optional). See the Parallel Kit Operator’s Manual.
NOTE: All connections to the parallel kit should be made while both inverters are turned off and all loads disconnected.

1. Make sure the Engine Economy Switch is in the same position on both generators.

2. Make appropriate parallel connections to the outlets on each inverter as outlined in the owner’s manual supplied with the kit.
   NOTE: Do not disconnect any parallel kit connections once the units are running.

3. Start both units per starting instructions. Once the green output indicator illuminates, devices can be connected and turned on using the parallel kit outlet.

4. Follow Generator Shut Down instructions.
   NOTE: For inverters, load applied to the parallel kit is not to exceed 3420 watts due to a 5% power loss when paralleling.
   See manual.
