Safety operation standards (top priority)
1. Environment and scene security
Only operate in well ventilated outdoor areas, away from closed or semi closed spaces such as doors, windows, ventilation openings, garages, basements, etc., to prevent carbon monoxide poisoning.
Maintain a ventilation gap of at least 5 feet (1.5 meters) around the generator, avoid flammable and combustible materials, and cool for at least 30 minutes after operation before storage or transportation.
Do not use in damp environments (rainy, snowy, or waterlogged), avoid skin contact with engine oil and gasoline, and wear protective equipment during operation.
2. Fuel safety operation
Before refueling, the engine must be turned off and cooled for at least 5 minutes. Smoking or being close to sources of ignition is prohibited to avoid fuel spillage.
Fuel should be stored in approved containers, in a well ventilated area, away from heat and ignition sources, and gasoline should not be used as a cleaning agent.
If there is a fuel leak, it should be wiped clean immediately, and the generator should be started only after the leak area is completely dry. Burning the leaked fuel is prohibited.
3. Electrical safety
It is prohibited to directly connect to the building's power grid unless the conversion switch is installed by a qualified electrician and complies with local electrical regulations.
Only use grounded three core extension cords, tools, and appliances, or double insulated equipment to avoid using worn or damaged wires.
When starting and shutting down the generator, it is necessary to disconnect all load connections and gradually add loads to avoid instantaneous overload.
4. Operation taboos
Not suitable for driving medical support equipment, operation is prohibited when fatigued, under the influence of alcohol, or under the influence of drugs.
During transportation or maintenance, it is necessary to disconnect the spark plug wire and battery connection to prevent accidental starting.
Avoid tilting or flipping the generator to prevent fuel or oil leakage.

Complete operational process
1. Preparation before startup
Check that the generator is placed in a horizontal, dry, and ventilated outdoor area, away from doors, windows, and flammable materials.
Confirm that the oil level is between the L (low) and H (high) marks on the dipstick. If it is insufficient, add the recommended model of oil (new engines do not have oil and need to be refilled for the first time).
Check that the fuel is sufficient, the fuel switch is in the off position, all loads have been disconnected, and the battery switch is in the off state.
Connect battery: Open the battery access cover, ensure the battery is securely fixed, connect the quick connector, and reset the battery cover.
2. Startup steps
Turn on the fuel switch (clockwise to the ON position).
Turn on the battery switch (press to the ON position).
Choose the startup method:
Backlash start: Slowly pull the recoil handle until resistance is felt, then quickly pull it.
Electric start: Long press the start/stop button on the control panel for 2 seconds.
Remote start: Long press the ON button on the remote control for 1 second (distance not exceeding 99 feet).
Maintenance Plan and Operation
1. Battery maintenance
After running for 30-60 minutes, the generator will automatically charge the battery. If not in use for a long time, the accompanying charger should be used to charge for 8 hours per month (no more than 8 hours to avoid overcharging).
