4. Setup
4.1 Unpacking and Inspection
- Carefully remove the generator from its packaging.
- Inspect for any shipping damage. Contact your dealer immediately if damage is found.
- Ensure all included accessories are present: DC cable, screwdriver, spark plug wrench, 30 amp RV adapter, fuel funnel.
4.2 Adding Engine Oil
The generator is shipped without engine oil. You must add the correct amount before first use.
- Place the generator on a level surface.
- Locate the oil fill cap/dipstick.
- Add the recommended engine oil (refer to specifications for type and quantity) using the provided funnel until it reaches the upper mark on the dipstick. Do not overfill.
- Securely replace the oil fill cap.
4.3 Adding Fuel
Use only fresh, unleaded gasoline with an octane rating of 87 or higher.
- Ensure the generator is turned off and cooled down.
- Open the fuel tank cap.
- Carefully pour unleaded gasoline into the fuel tank using the provided funnel. Do not fill above the red indicator line.
- Securely close the fuel tank cap.
5. Operating Instructions
5.1 Starting the Generator
- Ensure the generator is on a level, outdoor surface, away from any obstructions.
- Check oil and fuel levels.
- Turn the fuel valve to the "ON" position.
- If starting cold, move the choke lever to the "CHOKE" position.
- Press the electric start button or pull the recoil starter handle firmly until the engine starts.
- Once the engine starts, slowly move the choke lever to the "RUN" position.
- Allow the generator to warm up for a few minutes before connecting electrical loads.
5.2 Connecting Electrical Loads
- Ensure the generator is running stably.
- Plug your appliances or power cords into the appropriate outlets (120VAC or 12VDC).
- Do not exceed the generator's rated running wattage (3500W). Overloading will trigger the overload protection.
- For RV connections, use the included 30 amp RV adapter.
5.3 ECO Throttle Operation
- When the ECO throttle switch is in the "ON" position, the engine speed automatically adjusts to the electrical load, reducing fuel consumption and noise.
- For maximum power output or when starting high-load appliances, switch the ECO throttle to the "OFF" position.
5.4 Stopping the Generator
- Disconnect all electrical loads from the generator.
- Allow the generator to run for a few minutes without load to cool down.
- Turn the engine switch to the "OFF" position.
- Turn the fuel valve to the "OFF" position for storage.
6. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your generator. Always ensure the generator is off and cooled before performing any maintenance.
6.1 Engine Oil Change
- Change engine oil after the first 20 hours of operation, then every 100 hours or annually.
- Drain old oil when the engine is warm.
- Refill with recommended oil type and quantity.
6.2 Air Filter Cleaning
- Inspect and clean the air filter every 50 hours or more frequently in dusty conditions.
- Wash the foam element in warm, soapy water, rinse, and allow to dry completely. Lightly oil before reinstallation.
6.3 Spark Plug Inspection
- Inspect the spark plug every 100 hours or annually.
- Clean carbon deposits and adjust the gap if necessary. Replace if worn or damaged.
6.4 Fuel System
- If storing the generator for an extended period (over 30 days), drain the fuel tank and carburetor to prevent fuel degradation.
- Alternatively, use a fuel stabilizer.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine will not start | No fuel Low oil level Choke not set correctly Spark plug issue | Add fuel Add oil Adjust choke Inspect/clean/replace spark plug |
| No power output | Overload protection tripped Circuit breaker tripped ECO throttle engaged with high load | Reduce load, press RESET button Reset circuit breaker Disengage ECO throttle for high loads |
| Engine runs rough | Stale fuel Dirty air filter Spark plug issue | Drain and refill with fresh fuel Clean/replace air filter Inspect/clean/replace spark plug |
| Low oil indicator on | Low engine oil level | Check oil level and add oil as needed. The generator will shut down if oil is too low. |
If problems persist after attempting these solutions, please contact customer support.
