Safety operation standards

1. Environment and placement safety

Placement requirements: Use only in outdoor ventilated areas, at least 5 feet (1.5 meters) away from doors, windows, and ventilation openings; Place on a hard horizontal surface to avoid tilting and causing fuel/oil leakage.

Environmental restrictions: It is prohibited to operate in enclosed spaces (garages, basements, etc.) (exhaust containing carbon monoxide); Do not use in damp, rainy or snowy weather or near water sources (to prevent electric shock); The operating range of ambient temperature is 5 ° F (-15 ° C) -122 ° F (50 ° C). After storage, it needs to be restored to this range before restarting.

2. Fuel and Electricity Safety

Fuel operation:

Turn off the engine and cool it down for 2 minutes before refueling. Do not smoke or approach open flames; The fuel tank cannot be filled to its full capacity, leaving room for expansion. Any spilled fuel must be wiped dry and allowed to evaporate before starting.

The propane tank should be placed upright on the ground, away from heat sources and generator exhaust ports; After connecting, use soapy water to check if the interface is leaking (if there is bubbling, it is a leak). Do not start until the leak is eliminated.

Electricity operation:

It is prohibited to directly connect to the household power distribution system, and it must be connected through a qualified electrician installed conversion switch (to avoid reverse power transmission to the grid).

Only use grounded three core extension cables, with wire diameter matching the load and length (12 cable for 20A load ≤ 50 feet, 10 cable for ≤ 100 feet); Do not use damaged or aged cables.

Disconnect all loads before starting, and connect them in sequence after stable operation (first high-power equipment, then low-power equipment), with the total load not exceeding the rated power.

3. Personnel safety

Wear goggles and gloves during operation, curl up long hair, and avoid contact with high-temperature components such as exhaust pipes (which are prone to burns).

Do not operate after fatigue, drinking alcohol, or taking medication. Children and pets should stay away from running generators (at least 3 meters away).

If symptoms such as dizziness and nausea occur after inhaling carbon monoxide, immediately transfer to fresh air and seek medical attention if severe.

Operation process (assembly+start+stop)

1. Assembly and preparation

Installing wheels and handles: Fix the wheels to the frame with axle pins and split pins, and install and lock the handles with buckles.

Add engine oil: Place the generator horizontally, unscrew the oil filler cap, add the recommended model of engine oil to between the "L" and "H" marks on the dipstick, and tighten the dipstick.

Fuel preparation:

Gasoline: Open the fuel tank cap, add qualified gasoline, tighten the fuel tank cap, and clean any spilled fuel.

Propane: Connect one end of the matching hose to the propane inlet of the generator (manually tighten, no sealing tape required), and the other end to the propane tank valve. After opening the tank valve, check for leaks with soapy water.

Battery connection: Connect the battery quick connector to ensure a secure connection (both electric and remote start rely on the battery).

2. Start the process

Preprocessing: Turn the battery switch to "ON", the fuel selection switch to the corresponding fuel position (gasoline/propane), turn off all loads, and remote start requires pairing to be completed first (long press the pairing button on the control panel, then press the start stop button on the remote control).

Start operation:

Electric start: Press and hold the "START" button on the control panel for 2 seconds, then release it after the engine starts.

Remote control start: Press the "START" button on the remote control for 1 second, effective up to 30 meters away.

Hand pulled start: The refrigerator needs to close the air door, hold the starting rope and slowly pull it until there is resistance, then quickly pull it; After starting, gradually open the air door to the "RUN" position.

Stable operation: Run without load for 3-5 minutes to preheat, observe that the display screen parameters are normal (voltage and frequency are stable), and connect to the load after there is no abnormal noise.

3. Shutdown process

Normal shutdown: Disconnect all loads, let the generator run without load for 3-5 minutes, press the "STOP" button on the control panel or remote control, close the fuel valve (gasoline: close the tank valve; propane: close the tank valve), and finally close the battery switch.

Emergency shutdown: In case of leakage, abnormal noise, overload, etc., press the "STOP" button directly or turn off the engine switch to forcibly shut down.

Cleaning and tidying up: Disconnect fuel and power connections, clean equipment surfaces, and store hoses and cables.

Maintenance and Storage
