Safety operation standards (core focus)

1. High risk warning and contraindications

Risk of carbon monoxide poisoning: It is strictly prohibited to use it in enclosed/semi enclosed spaces such as indoors, garages, and basements. It can only be operated in outdoor ventilated areas and kept away from doors, windows, ventilation openings, and air conditioning inlets. It is recommended to install carbon monoxide detectors.

Fire and explosion risks: The vehicle must be shut down and cooled down for at least 2 minutes before refueling; Do not overfill (the oil level should not exceed the red filling ring in the fuel tank); Keep away from sources of fire, sparks (cigarettes, static electricity); When there is a fuel leak, it is necessary to wipe it clean immediately and wait for the area to dry before starting.

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.

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.

2. General safety requirements

Maintain a clearance of at least 5 feet (1.5 meters) around the device during operation, including above; 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.

Cool down for 30 minutes before transportation, keep it level, and if necessary, empty the fuel to prevent leakage; Keep away from sources of fire and heat (such as water heaters, stoves, etc.) during storage.

Battery maintenance: The battery contains sulfuric acid electrolyte (corrosive) and lead compounds, and protective equipment should be worn during operation; No smoking or proximity to fire sources; Prohibit wires and tools from crossing the two poles of the battery; If the acidic solution comes into contact with the skin, immediately rinse with water and apply baking soda to neutralize it.

Assembly and start-up process

1. Open box inspection and assembly

(1) List of unboxing items

Core components: generator host, wheel assembly (2 pieces), lifting hook, battery (36AH), battery charger.

Tools and consumables: spark plug socket wrench, assembly wrench, funnel, M8 flange bolts (4 pieces), split pins (4 pieces), washers (4 pieces), SAE 10W-30 engine oil (1 bottle).

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

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

Wheel installation: Place the generator on a horizontal surface, insert the axle pin through the washer and wheel, insert it into the frame axle bracket, fix it with an open pin, and repeat the operation on the other side (the wheel is only used for manual handling and dragging is prohibited).

Installation of lifting hook: Align the top fuel tank bracket with the lifting hook and tighten it with 4 M8 flange bolts (only used for lifting or fixing the binding strap, do not grip other components for handling).

Battery installation: First, connect the red positive cable to the positive pole of the battery and cover it with a protective sleeve, then connect the black negative cable; Use insulated tools to avoid short circuits between the positive and negative poles.

2. Preparation before startup

Location selection: Outdoor ventilated area, at least 5 feet away from buildings and combustibles, on a horizontal dry surface, avoiding loose materials (such as sand and 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 (copper wire ≥ 10 AWG) is required.

3. Startup and shutdown operations

(1) Start the process

Turn the fuel valve to the "ON" position.

Cold machine: fully pull out the air damper; Heat engine: Set the choke to the middle or "RUN" position.

Press the start switch to "START" and hold for up to 5 seconds (to avoid overheating of the starter motor); After successful startup, release and warm up for 3-5 minutes.

After the engine runs steadily, slowly push back the choke to the "RUN" position.

(2) Shutdown process

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

Emergency stop: Simply turn the switch to "OFF" (only for use in case of malfunction or danger).

Key maintenance operation details

(1) Oil change

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

Remove the oil drain hose, open the valve to drain the oil, close the valve and secure the hose.

Disassemble the old oil filter counterclockwise and clean the installation surface; Apply a small amount of engine oil to the rubber sealing ring of the new filter, manually tighten it until it fits snugly, and then tighten it 3/4 turn (do not overtighten).

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

(2) Battery maintenance

Charging: The generator can recharge the battery after running for 30-60 minutes; Long term use of the included trickle charger (connected to the control panel charging port), red light charging in progress, green light fully charged.

Replacement: First disconnect the negative cable, then disconnect the positive cable; The installation sequence of new batteries is reversed (connect the positive electrode first), part number 511075 (36AH), and used batteries need to be disposed of according to local regulations.

(3) Storage maintenance

Key points for storage duration operation

No special treatment is required within one month to maintain normal oil and fuel levels

Add fresh fuel and fuel stabilizer every 2-6 months, and empty the carburetor float

Drain the fuel tank and carburetor fuel after more than 6 months; 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); After cleaning the equipment, store it in a dry and ventilated place, and do not cover it with plastic sheeting (which is prone to moisture and rust)

Common troubleshooting

Possible causes and solutions for the fault phenomenon

The engine cannot start. 1. The battery switch is turned off or running low; 2. Insufficient/deteriorated fuel; 3. Air filter blockage; 4. Low oil level (low oil protection); 5. Spark plugs are damp/faulty/have improper clearances; 6. Fuel filter blockage 1. Turn on the battery switch or charge; 2. Add fresh fuel; 3. Clean/replace the filter; 4. Add engine oil; 5.
