Battery replacement: Disconnect the battery and connect the new battery (part number 511019) to the positive and negative poles (red+, white -). Secure the battery strap and reset the battery cover. Dispose of used batteries according to local regulations.
2. Storage maintenance
(1) Short term storage (<1 month)
Clean the surface of the generator, remove the protective cover of the control panel, store in a dry, ventilated place, away from fire and heat sources.
Keep the battery charged once a month to ensure sufficient power for the next use.
(2) Mid term storage (2-6 months)
Add fresh fuel and fuel stabilizer, run the generator for 5 minutes, and allow the stabilizer to circulate throughout the entire fuel system.
Drain the fuel from the carburetor float chamber to avoid the formation of gum and carbon deposits.
Turn off the battery switch, charge once a month, and cover with a dust cover (plastic cover is prohibited to prevent moisture accumulation).
(3) Long term storage (>6 months)
Drain the fuel from the fuel tank (using a manual fuel pump for extraction, electric fuel pumps are prohibited), and clean the fuel filter.
Drain the fuel from the carburetor float chamber, remove the spark plug, inject 1 teaspoon of engine oil into the cylinder, pull the recoil lever to the piston compression stroke (valve closed), and then install the spark plug (without wiring).
Disconnect the battery, store it separately and charge it regularly. Place the generator in a dry, ventilated, and cool place.

Common troubleshooting
Possible causes and solutions for the fault phenomenon
The engine cannot start due to battery switch OFF, insufficient fuel, or fuel deterioration. Open the battery switch and add fresh fuel. If the fuel deteriorates, empty the fuel tank and clean the fuel system
The air filter is dirty and the low oil level triggers a shutdown for cleaning or replacing the air filter. Add engine oil to the standard level
Wait for 5 minutes until the spark plug is wet (flooded), faulty, or has improper clearance, and then pull the recoil handle to exhaust; Disassemble the spark plug, dry or replace it, and adjust the gap to the specified value
Start the battery with recoil when it runs out of power, or charge it for 8 hours with the included charger
Immediately stop the engine after starting, if there is insufficient fuel, abnormal oil level, or clogged air filter, add fuel, check and adjust the oil level, and clean the air filter
Fuel pollution, low fuel level switch malfunction. Drain the fuel tank and add fresh fuel. If the problem is not resolved, contact customer service
The generator lacks power, the air filter is clogged, the fuel has deteriorated or contaminated. Clean or replace the air filter, empty the old fuel and add fresh fuel
Fuel filter blockage, ignition system malfunction, contact authorized service provider for maintenance
Unstable engine operation/engine shutdown, dirty air filter, generator overload, clean air filter, disconnect partial load, ensure total load does not exceed rated power
Replace or repair faulty equipment due to tool or electrical malfunction, and restart the generator
The overload indicator light of the AC socket without output is on, and the circuit breaker trips to disconnect all loads. Press the overload reset button to reset the circuit breaker and check if the load power exceeds the standard
Output ready light not on, equipment failure. Restart the generator and check if the equipment is normal. If there is still no output, contact customer service
Product registration and after-sales support
After starting, wait for the engine speed to stabilize and the output ready indicator light (green) to light up before connecting the load.
ECO mode on: Only used when there is no heavy load. Press the ECO mode switch, and the engine will adjust its speed according to the load, reducing fuel consumption and noise; When driving large start-up loads such as air conditioning and water pumps, the ECO mode needs to be turned off.
3. Operation and load management
The total power of the load shall not exceed 3900 watts (operating power), and the total starting load shall not exceed 5000 watts (peak power).
Load connection sequence: Start the generator first, connect the maximum load after it stabilizes, and then add other loads in sequence. Connect each load and wait for the generator to stabilize.
Extension cable selection: An outdoor dedicated three core grounding extension cable should be used, and the cable diameter should be selected according to the load current (such as using a 10 gauge cable with a length not exceeding 100 feet for a 20A load).
4. Shutdown steps
Disconnect all connected loads, turn off the electrical switch, and unplug the plug.
Run the generator without load for 3-5 minutes to stabilize the internal temperature.
Press the start/stop button on the control panel for 1 second, or the OFF button on the remote control for 1 second.
Turn off the battery switch (press to OFF position) and turn off the fuel switch (turn counterclockwise to OFF position).
If not used for a long time, the fuel and battery should be disposed of according to storage requirements.
