Key Features
- Dual Fuel Capability: Operates on both gasoline and LPG (Liquefied Petroleum Gas). LPG operation offers increased fuel economy without compromising power output. Includes two pressure regulators and a gas hose for LPG connection.
- Eco-Friendly Operation: Features a 15-liter gasoline tank, compatible with unleaded gasoline or propane/butane. Provides up to 15 hours of runtime at 50% load. LPG operation is more environmentally friendly and quieter, reduces vibrations, and extends engine life.
- High-Quality Construction: Equipped with a copper winding alternator, ensuring reliable and durable operation even under maximum load. This distinguishes the KS3000G from models with aluminum windings.
- Safety Features: Includes an integrated Automatic Voltage Regulator (AVR), fuel indicator, and a user-friendly control panel with an LED display showing operating hours, frequency, and voltage. Features oil level protection and an overload protection switch.
- Reliable Performance: Powered by a four-stroke engine with a maximum output of 3000 W and a rated output of 2600 W. Features one 12V DC outlet and two 16A 230V AC outlets. Built with a reinforced steel frame, an improved anti-vibration system, and galvanic surface protection.

Operating Instructions
1. Pre-Operation Checklist
- Ensure the generator is placed on a level, stable surface outdoors, away from flammable materials.
- Check engine oil level.
- Verify fuel level (gasoline) or LPG connection.
- Ensure all electrical devices are disconnected from the generator outlets.
2. Starting the Generator
For Gasoline Operation:
- Turn the fuel valve to the "ON" position.
- Set the engine switch to "ON".
- Pull the choke lever to the "CHOKE" position (if engine is cold).
- Pull the recoil starter handle firmly until the engine starts.
- Once the engine starts, gradually push the choke lever back to the "RUN" position.
For LPG Operation:
- Ensure the gasoline fuel valve is "OFF".
- Open the valve on the LPG cylinder.
- Set the engine switch to "ON".
- Pull the choke lever to the "CHOKE" position (if engine is cold).
- Pull the recoil starter handle firmly until the engine starts.
- Once the engine starts, gradually push the choke lever back to the "RUN" position.
3. Connecting Electrical Devices
Once the generator is running smoothly, you can connect your electrical devices to the appropriate outlets (230V AC or 12V DC). Do not exceed the generator's rated output.

4. Shutting Down the Generator
- Disconnect all electrical devices.
- If operating on gasoline, turn the fuel valve to the "OFF" position and allow the engine to run until it stops from fuel starvation. This helps prevent carburetor issues.
- If operating on LPG, close the valve on the LPG cylinder and allow the engine to run until it stops.
- Set the engine switch to "OFF".
Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your generator. Always ensure the generator is turned off and cooled down before performing any maintenance.
1. Engine Oil Change
Change the engine oil after the first 20 hours of operation, and then every 50-100 hours or annually, whichever comes first. Refer to the user manual for the exact procedure and recommended oil type.
2. Air Filter Cleaning/Replacement
Inspect the air filter every 50 hours of operation or more frequently in dusty conditions. Clean or replace the filter as necessary to ensure proper engine breathing.
3. Spark Plug Inspection/Replacement
Check the spark plug every 100 hours or annually. Clean any carbon deposits and adjust the gap if needed. Replace if the electrode is worn or damaged. Use the provided spark plug wrench.
4. Fuel System Maintenance (for Gasoline)
If storing the generator for an extended period, drain the gasoline from the fuel tank and carburetor to prevent fuel degradation and clogging. Alternatively, use a fuel stabilizer.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine does not start. | No fuel (gasoline/LPG), low oil level, engine switch OFF, choke incorrect, fouled spark plug. | Add fuel, fill oil to correct level, turn engine switch ON, adjust choke, clean/replace spark plug. |
| No power output. | Overload protection tripped, circuit breaker tripped, faulty connection. | Reduce load, reset circuit breaker, check connections. |
| Engine runs rough or stalls. | Stale fuel, clogged fuel filter, dirty air filter, incorrect choke setting. | Drain/replace fuel, clean/replace fuel filter, clean/replace air filter, adjust choke. |
| Excessive vibration. | Generator not on level surface, loose anti-vibration supports. | Place on level surface, tighten anti-vibration supports. |
If the problem persists after attempting these solutions, please contact customer support.
