4. Setup
4.1. Unpacking and Inspection
- Carefully remove the generator from its packaging.
- Inspect the unit for any signs of damage that may have occurred during shipping. Contact your dealer immediately if damage is found.
- Ensure all components listed in the packing list are present.
4.2. Wheel and Handle Assembly
The generator is equipped with a driving device (wheels and handles) for easy transport. Follow the instructions provided in the separate assembly guide or diagrams to attach the wheels and handles securely.
4.3. Adding Engine Oil
- Place the generator on a level surface.
- Locate the oil filler cap/dipstick.
- Remove the cap and slowly add the recommended engine oil (refer to specifications for oil type and capacity) until it reaches the upper mark on the dipstick. Do not overfill.
- Securely replace the oil filler cap.
4.4. Adding Diesel Fuel
- Ensure the generator is turned off and cool.
- Open the fuel tank cap.
- Carefully pour clean diesel fuel into the tank, using a funnel to prevent spills. Do not fill above the maximum level indicator. The tank capacity is 16 liters.
- Securely close the fuel tank cap. Wipe up any spilled fuel immediately.
5. Operating Instructions
5.1. Pre-Operation Checks
- Check engine oil level.
- Check fuel level.
- Ensure the generator is on a level, stable surface.
- Verify that all circuit breakers are in the 'OFF' position before starting.
5.2. Starting the Generator (Electric Start)
- Turn the fuel valve to the 'ON' position.
- If the engine is cold, move the choke lever to the 'CHOKE' position.
- Insert the key into the ignition switch and turn it to the 'START' position. Release the key once the engine starts.
- Once the engine has warmed up (after a few seconds), gradually move the choke lever back to the 'RUN' position.
- Allow the generator to run for a few minutes before connecting any electrical loads.
5.3. 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 ignition key to the 'OFF' position.
- Turn the fuel valve to the 'OFF' position.
5.4. Connecting Electrical Loads
- Ensure the generator is running stably before connecting devices.
- Plug your electrical devices into the appropriate 230V, 400V, or 12V sockets.
- Turn the circuit breakers on the control panel to the 'ON' position.
- Do not exceed the generator's rated output (5000 Watts). Overloading will trip the circuit breaker and can damage the generator or connected devices.
6. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your generator. Always ensure the engine is off and cool before performing any maintenance.
- Daily/Before Each Use: Check engine oil level, check fuel level, inspect for any leaks or loose connections.
- Every 20 Hours or Monthly: Clean the air filter. Replace if necessary.
- Every 50 Hours or 3 Months: Change engine oil. Inspect spark plug (if applicable, for diesel, check fuel filter).
- Every 100 Hours or 6 Months: Inspect fuel filter, clean cooling fins.
- Storage: For long-term storage, drain the fuel tank and carburetor (if applicable), change the engine oil, and store in a dry, protected area.
