Safety Information

Your safety and the safety of others are very important. Always follow the safety precautions listed below to reduce the risk of fire, electric shock, and personal injury.

Carbon Monoxide Hazard

• Never operate the generator indoors or in partially enclosed areas. Exhaust contains carbon monoxide, a colorless, odorless, poisonous gas that can kill you.
• Always operate the generator outdoors in a well-ventilated area, far away from windows, doors, and vents.
• Install carbon monoxide alarms in your home.

Fire and Burn Hazard

• Gasoline is highly flammable. Store fuel in an approved container in a well-ventilated area away from ignition sources.
• Do not refuel a hot or running engine. Allow the generator to cool before adding fuel.
• Keep flammable materials away from the generator during operation.
• Engine components become very hot during operation and can cause severe burns.

Electrical Shock Hazard

• Never operate the generator in wet conditions.
• Do not connect the generator directly to your home's electrical system without a transfer switch installed by a qualified electrician. Backfeeding can electrocute utility workers.
• Ensure all electrical connections are secure and in good condition.

Setup and Assembly

Before operating your generator, some initial setup steps are required.

1. Unpacking and Inspection

• Remove the generator and all components from the packaging.
• Inspect for any shipping damage. Contact your dealer immediately if damage is found.
• Ensure all parts listed in the packing list are present. The wheel kit is included for portability.

2. Wheel Kit Assembly

The wheel kit allows for easy movement of the generator. Follow the instructions provided with the wheel kit for proper installation. Typically, this involves attaching the wheels and support legs to the generator frame.

3. Add Engine Oil

• Place the generator on a level surface.
• Remove the oil fill cap/dipstick.
• Add the recommended engine oil (refer to specifications for type and capacity) until it reaches the full mark on the dipstick. Do not overfill.
• Securely replace the oil fill cap/dipstick.

4. Add Fuel

• Ensure the generator is turned off and cool.
• Use only fresh, unleaded gasoline with an octane rating of 87 or higher.
• Slowly fill the fuel tank, being careful not to overfill. Leave space for fuel expansion.
• Securely replace the fuel cap.

Operating Instructions

Follow these steps to safely start and operate your generator.

Starting the Engine

1. Position the Generator: Place the generator outdoors on a level surface, away from windows and doors, with adequate ventilation.
2. Check Fuel and Oil Levels: Ensure there is sufficient fuel and the oil level is correct.
3. Turn Fuel Valve ON: Locate the fuel valve and turn it to the "ON" position.
4. Set Choke: Move the choke lever to the "CHOKE" position (cold engine start). For a warm engine, the choke may not be necessary.
5. Turn Engine Switch ON: Locate the engine switch on the control panel and turn it to the "ON" position.
6. Pull Starter Cord: Firmly grasp the starter handle and pull the cord slowly until resistance is felt, then pull quickly and smoothly. Repeat until the engine starts.
7. Adjust Choke: Once the engine starts, slowly move the choke lever to the "RUN" position.

Connecting Electrical Loads

• Allow the engine to run for a few minutes to warm up before connecting electrical devices.
• Plug appliances directly into the generator's outlets using appropriate extension cords.
• Do not overload the generator. The total wattage of connected devices should not exceed the generator's running wattage (3500 watts).
• Start connecting devices one at a time, from largest to smallest load.

Stopping the Engine

1. Disconnect Loads: Unplug all electrical devices from the generator outlets.
2. Turn Engine Switch OFF: Move the engine switch to the "OFF" position.
3. Turn Fuel Valve OFF: Close the fuel valve to prevent fuel flow.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your generator. Always perform maintenance with the engine off and cool.

Maintenance Schedule

Storage

For long-term storage (more than 30 days), prepare your generator as follows:

• Drain the fuel tank and carburetor, or add a fuel stabilizer.
• Change the engine oil.
• Remove the spark plug and pour a small amount of engine oil into the cylinder. Pull the starter cord a few times to distribute the oil, then reinstall the spark plug.
• Clean the exterior of the generator.
• Store in a clean, dry, well-ventilated area.

Troubleshooting

This section provides solutions to common operational issues.

Engine Will Not Start

• No Fuel: Check fuel level and add fresh gasoline if needed.
• Fuel Valve OFF: Ensure the fuel valve is in the "ON" position.
• Engine Switch OFF: Ensure the engine switch is in the "ON" position.
• Choke Position: Adjust choke for cold or warm start conditions.
• Low Oil Shutdown: Check engine oil level. If too low, the generator's low-oil sensor will prevent starting. Add oil if necessary.
• Spark Plug: Inspect spark plug for fouling or damage. Clean or replace if needed.

No Power Output

• Circuit Breaker Tripped: Check the circuit breakers on the control panel. Reset if tripped.
• Overload: Reduce the number of connected appliances.
• Faulty Cord/Appliance: Test with a different appliance or extension cord.
• GFCI Tripped: If equipped, reset any GFCI outlets.
