Safety operation standards (core focus)

1. High risk warning and contraindications

Risk of carbon monoxide poisoning: It is strictly prohibited to use in enclosed/semi enclosed spaces such as indoors, garages, and basements. It can only be operated in outdoor ventilated areas and kept at least 15 feet (4.5 meters) away from doors, windows, ventilation openings, and air conditioning air intakes; Suggest installing a carbon monoxide detector.

Fire and explosion risks: The machine must be stopped and cooled down before refueling; Do not overfill (the oil level should not exceed the neck of the fuel tank filling port); Keep away from sources of fire, sparks (cigarettes, static electricity); When there is a fuel leak, wipe it clean immediately and wait for the area to dry before starting; Do not store fuel indoors during storage.

Electric shock risk: Do not use in damp environments, rainy or snowy weather; Do not touch live terminals and exposed wires during equipment operation; Use grounded three core extension cables and prohibit the use of damaged or aged cables; The connection to the building power grid must be installed by a certified electrician to ensure isolation from the mains power supply.

Other taboos: Not suitable for powering medical equipment; Prohibition of modifying equipment; Overloading operation is prohibited; Do not move or tilt the device while it is running; Prohibit starting with load.

2. General safety requirements

Ensure that there are no obstacles around the equipment during operation and avoid touching high-temperature components such as mufflers and engines (after cooling); Wear protective equipment (gloves, goggles) to avoid direct skin contact with engine oil and gasoline; Wash hands promptly after operation.

Before starting, all loads must be disconnected to avoid damaging the equipment during loaded startup; Grounding must comply with local regulations. If connecting to building systems, an electrician must confirm whether a grounding rod (copper wire ≥ 10 AWG) is required.

Before transportation, the equipment needs to be cooled down and kept level. If necessary, the fuel should be drained; When storing, keep away from sources of fire and heat (such as water heaters, stoves, etc.), and do not use wires or tools to cross the two poles of the battery (if it is an electric starting model).

Assembly and start-up process

1. Open box inspection and assembly

(1) List of unboxing items

Core components: Generator host, wheel assembly (2 pieces), axle pin (2 pieces), washer (2 pieces), M8 × 16mm flange bolt (4 pieces), split pin (2 pieces).

Tools and consumables: spark plug socket wrench, funnel, 1.1L SAE 10W30 engine oil.

Documents: User Manual, Quick Launch Guide, Product Registration Card.

(2) Assembly steps (requiring collaboration between two people to avoid single person handling)

Foot installation: Place the generator on a flat surface and fix the feet on both sides of the frame with M8 flange bolts to ensure a secure installation.

Wheel installation: Insert the axle pin through the washer and wheel into the frame axle bracket, ensuring that the bolt hole faces inward towards the generator; Lock the axle pin hole with an open-ended pin, and repeat the operation on the other side (the wheel is only used for manual movement, dragging or road driving is prohibited).

2. Preparation before startup

Location selection: Outdoor ventilated area, at least 15 feet (4.5 meters) away from buildings and combustibles, on a horizontal and dry surface, avoiding loose materials (sand, grass debris) to prevent blockage of air vents.

Oil inspection:

Engine oil: The new machine has no engine oil and needs to be added to the "MAX" mark on the dipstick (place the cold machine horizontally, wipe the dipstick dry, fully screw it in, and then remove it for inspection).

Fuel: Add unleaded 87-93 gasoline with ethanol content ≤ 10%; Clean the fuel tank after refueling and check for leaks.

Load and grounding: Disconnect all electrical equipment connections; Grounding must comply with local regulations. If connecting to building systems, an electrician must confirm whether a grounding rod is required.

3. Startup and shutdown operations

(1) Start the process

Turn the fuel valve to the "ON" position.

Cold machine: Turn the air damper to "ON"; Heat engine: Set the choke to "OFF".

Push the engine control switch to 'RUN'.

Slowly pull the recoil start rope until the resistance increases, and quickly pull upwards to start (the longest single pull should not exceed 5 seconds, failure should be attempted again with a 10 second interval).

After the engine starts, wait for the RPM to stabilize and gradually retract the choke to "OFF".

Connect electrical equipment (following the principle of "high power first, low power later" to avoid overloading).

(2) Shutdown process

Normal shutdown: Disconnect all loads → Run without load for 3-5 minutes → Turn the engine control switch to "STOP" → Close the fuel valve; Long term non use requires closing the fuel valve and allowing the engine to run until it shuts down on its own (depleting the fuel in the carburetor).

Emergency stop: Simply turn the engine control switch to "STOP" (only used in case of malfunction or danger).

Key maintenance operation details

(1) Oil change

Place the refrigeration unit horizontally, clean the area around the oil discharge port, and place the oil pan.

Remove the oil drain plug, drain the old oil, close the drain plug and tighten it.

Add recommended engine oil to the "MAX" mark on the dipstick through the oil filler port, install the dipstick and filler cap, start the engine and check for leaks.

Waste engine oil should be disposed of according to environmental protection requirements and should not be dumped into sewers, ground or water sources at will.

(2) Evacuation of carburetor float (before long-term storage)

Stop the generator for cooling, keep away from sources of fire, and place a container under the carburetor.

Loosen the bottom screw of the carburetor float, drain the remaining fuel, and tighten the screw.

(3) Storage maintenance

Key points for storage duration operation

No special treatment is required within one month, keep the oil and fuel normal, and regularly check the fluid level

Clean the equipment after more than one month → Drain the fuel tank and carburetor float → Change the engine oil → Inject 1 tablespoon of engine oil into the spark plug hole, pull the starting rope to make the piston run (protect the cylinder wall) → Clean the spark arrester → Store in a dry and ventilated place, away from fire sources

Common troubleshooting

Possible causes and solutions for the fault phenomenon

The engine is running but there is no power output. 1. The circuit breaker has tripped; 2. The power cord is not securely plugged in; 3. Power cord/electrical equipment malfunction; 4. GFCI socket tripped; 5. Internal equipment malfunction: 1. Reset the circuit breaker and check for overload; 2. Re plug the plug (the 240V socket needs to be turned clockwise by 1/4 turn); 3. Replace the power cord or test the normal equipment; 4. Press the GFCI reset button; 5. Send to authorized service points

The engine cannot start/stalls after starting. 1. The fuel valve is closed; 2. Lack of fuel/deterioration of fuel; 3. Blockage of oil circuit; 4. The air filter is dirty; 5. Low oil level (low oil protection); 6. Spark plug malfunction/improper clearance; 7. Spark eliminator blockage 1. Open the fuel valve; 2. Add fresh fuel; 3. Clean the oil circuit; 4. Clean/replace the filter; 5. Add engine oil; 6. Adjust/replace spark plugs; 7. Clean the spark eliminator; If it is invalid, send it for repair

Sudden shutdown of generator: 1. Lack of oil; 2. Low oil level (low oil protection); 3. Excessive load 1. Oil replenishment; 2. Add engine oil; 3. Reduce load after restart; If it is invalid, send it for repair

Unstable engine operation/speed fluctuation 1. Air filter blockage; 2. Frequent load switching; 3. Equipment malfunction: 1. Clean the filter; 2. Load fluctuations are a normal phenomenon and do not require any handling; 3. Send to authorized service points

GFCI socket has no power. 1. The socket trips; 2. Socket malfunction: Press the reset button; 2. Send for repair and replacement of sockets
