Connecting Electrical Devices
After the generator is running stably, you can connect your electrical devices. The generator features:
- 1 x 120V 30 amp RV outlet
- 2 x 120V 20 amp outlets
- 2 x 5V DC USB outlets
Ensure the total wattage of connected devices does not exceed the running wattage of 3000W. For sensitive electronics, the inverter technology provides clean pure sine wave power, protecting your devices.
Eco Mode Operation
The generator features an Eco mode switch. When activated, the engine speed automatically adjusts to the load, improving fuel efficiency and reducing noise levels. This extends run time up to 8.3 hours at 25% load (750W) or 4.5 hours at 50% load (1500W).
Stopping the Generator
- Disconnect all electrical devices from the generator.
- Turn the engine switch to the 'OFF' position.
- Turn the fuel valve to the 'OFF' position (if applicable).
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.
Engine Oil Change
Change the engine oil after the first 20 hours of operation, and then every 100 hours or every 6 months, whichever comes first. Refer to the owner's manual for detailed steps on draining and refilling the oil.
Spark Plug Inspection and Replacement
Inspect the spark plug every 100 hours or annually. Clean or replace if necessary. Use the provided spark plug socket wrench for removal and installation.
Air Filter Cleaning
Clean the air filter every 50 hours or every 3 months, or more frequently in dusty conditions. A dirty air filter can reduce engine performance and increase fuel consumption.
Storage
For long-term storage, drain the fuel from the tank and carburetor, or add a fuel stabilizer. Change the engine oil. Store the generator in a clean, dry place, covered with the provided dust cover.
