Adjust the air intake volume with the throttle knob (only used when manually pulled to start). Close (push in) when starting the cold engine, and open (pull out) when the hot engine or stable operation is achieved

After the GFCI reset button leakage protection trips, it is necessary to investigate the cause of the leakage before resetting to ensure that the equipment has no faults

When the main circuit breaker is overloaded, it will automatically trip. After cutting off the main power supply and tripping, the load needs to be reduced. Press the circuit breaker to reset

The CO alarm indicator light (red) lights up when the CO concentration exceeds the standard. At the same time, the generator needs to be stopped and moved to a ventilated area. After checking the environment, it can be restarted

Safety operation standards (including risk avoidance)

1. Environment and placement safety

Core requirements for placement:

Only use in fully open and well ventilated outdoor areas, at least 20 feet (about 6 meters) away from doors, windows, ventilation openings, tents, etc., to prevent carbon monoxide emissions from entering indoors.

Place on a hard, horizontal surface, avoiding tilting (angle ≤ 5 °), to prevent fuel leakage or uneven oil lubrication from causing engine wear.

At least 5 feet (about 1.5 meters) of heat dissipation space should be reserved around the fuselage, away from flammable materials such as hay, wood, paint, gasoline, etc. The exhaust port should face unmanned areas.

Environmental limitations and responses:

Operating temperature range: 5 ° F (-15 ° C) to 122 ° F (50 ° C). If it is below -15 ° C, it is necessary to replace the winter specific oil (5W-30) and keep the battery warm (to avoid power loss).

Prohibited scenarios: rainy, snowy, or damp ground (to prevent electric shock); Dust and corrosive gases (such as salt spray at the seaside and chemical plant areas) can easily cause component corrosion and blockage.

Extreme weather: In rainstorm days, a temporary canopy (not sealed, ensure ventilation) shall be built to avoid rain splashing the engine and control panel.

2. Fuel safety operation

Preparation before refueling:

Turn off the engine and wait for at least 2 minutes for it to cool down (the exhaust pipe temperature can reach over 400 ℃, which can easily ignite the fuel).

Clean the oil and dust around the fuel tank cap to prevent impurities from entering the fuel tank; Prepare a qualified fuel can and do not pour it directly from a bucket.

Refueling operation specifications:

Slowly add fuel, with the fuel level not exceeding the red limit ring inside the fuel tank (with 5-10% expansion space reserved), to avoid fuel spillage during high temperatures.

If fuel overflows, immediately wipe it clean with a dry cloth and wait for the fuel to completely evaporate before starting the engine (do not ignite immediately).

Fuel storage and handling:

Backup fuel should be stored in a compliant fuel container, in a well ventilated, cool, and away from sources of ignition. The storage time should not exceed 3 months (with the addition of fuel stabilizers, it can be extended to 6 months).

Degraded fuel must be handed over to professional institutions for recycling, and it is prohibited to dump it indiscriminately (which pollutes the environment and is flammable).

Forbidden operation: Do not refuel while the engine is running; Do not use fuel to clean the body or components; Do not place fuel containers on the generator or near heat sources.

3. Electricity safety regulations

Extension cable selection:

Outdoor dedicated, undamaged, and well grounded three core cables must be used, and the cable specifications must match the load:

20A load (such as small electric tools): Use a 12 gauge cable with a length ≤ 50 feet; 14 gauge cable, length ≤ 25 feet.

30A load (such as 3kW air conditioner): Use 10 gauge cable with a length ≤ 50 feet; Number 8 gauge cable, length ≤ 100 feet.

50A load (if multiple devices are powered simultaneously): Use gauge 6 cable with a length ≤ 50 feet.

It is prohibited to use two core ungrounded cables, damaged cables, or multiple cables connected in series (which are prone to heating and leakage).

Load access principle:

Before starting, all loads must be disconnected to avoid overload triggering protection during startup.

After the generator runs stably (no-load for 3-5 minutes), connect high-power devices (such as air conditioning and water pumps) first, and then connect low-power devices (such as lights and mobile phone chargers), with a total operating power of ≤ 9500W and a total starting power of ≤ 12500W.

The starting power of inductive loads (motors) is 3-5 times the operating power and needs to be calculated separately to avoid multiple inductive loads starting simultaneously (such as a 3kW air conditioner and a 2kW water pump, the starting power may exceed 12500W).

Grounding and grid connection requirements:

The neutral wire of the generator is connected to the metal casing of the machine body and does not require additional grounding; If it is necessary to connect to the household fixed power distribution system, a certified electrician must install an automatic transfer switch (direct grid connection is prohibited to avoid reverse power transmission to the grid).

When connecting metal shell equipment (such as power tools, water pumps), ensure that the equipment is well grounded to avoid electric leakage and shock.

Emergency handling of faults: If equipment trips, heats up, or emits odors during power consumption, immediately disconnect the load, shut down the generator, and troubleshoot (such as overload or short circuit) before use; If there is electric leakage or shock, immediately cut off the power supply and seek medical attention in severe cases.

4. Personnel safety protection

Operation protection: goggles must be worn (to prevent fuel splashing and debris from entering the eyes), gloves must be worn (to prevent oil contamination and burns); Long hair should be curled up to avoid getting caught up in moving parts.

Personnel management: Children and pets should stay away from the running generator (at least 5 feet away); Do not operate the generator when fatigued, under the influence of alcohol, or after taking medication (which affects judgment).

Emergency response:

If you experience symptoms such as dizziness, nausea, and fatigue after inhaling carbon monoxide, immediately move to fresh air and seek medical attention in severe cases (carbon monoxide is colorless and odorless, so be alert).

If burns occur (due to contact with high-temperature components such as exhaust pipes), immediately rinse the burned area with cold water, and seek medical attention in severe cases.

If a fire occurs, use ABE or BE type fire extinguishers to extinguish it (it is prohibited to directly extinguish electrical or fuel fires with water).

Complete operation process (assembly → start → run → stop)

1. First use assembly and preparation

Open box inspection:

Remove the generator and its accessories (tripod, roller, tool kit, engine oil, battery, remote control, manual).

Check that the appearance of the generator is undamaged, the components are not loose, the sockets and switches are functioning properly, and the battery is fully charged.

Install the tripod and roller:

Tilt the generator (ensuring that the fuel valve is closed to avoid fuel leakage), and use the accompanying bolts and wrenches to secure the tripod on both sides of the bottom of the body.

Install the roller into the slot below the tripod, tighten the fixing bolts to ensure that the roller rotates flexibly and is securely installed (which can drive the generator to test stability).

Add engine oil:

Place the generator on a level surface, open the oil filler cap on the left side of the body, and remove the dipstick.

Slowly add the recommended model of engine oil (SAE 10W-30) and check the dipstick while adding until the oil level is between the "L" (lowest) and "H" (highest) marks (not exceeding the "H" mark to avoid excessive oil accumulation and oil leakage).

Tighten the oil filler cap and dipstick, and wipe off any remaining oil with a dry cloth.

Add fuel:

Unscrew the fuel tank cap (counterclockwise) and clean the impurities around the fuel inlet.

Add unleaded gasoline with a fuel level not exceeding the red limit ring inside the fuel tank, and tighten the fuel tank cap (clockwise).

Check for leaks at the connection between the fuel tank and oil pipe. If there is any overflow, wipe it clean immediately.

Battery connection:

Find the battery quick connector on the side of the body (red positive pole, black negative pole), align the battery connector with the body connector and insert it. When you hear a "click" sound, it will lock (the connector is pre installed at the factory and does not require additional wiring).

Turn on the battery switch (to the "ON" position) and check if the control panel data center is lit up (confirm that the battery power supply is normal).

2. Startup process (detailed explanation of three startup methods)

(1) Remote start (recommended, convenient and efficient)

Preprocessing: Confirm that the fuel valve is "ON", the battery switch is "ON", all loads are disconnected, and the generator is placed for horizontal ventilation.

Start operation: Press the "START" button on the remote control for 1 second, and release it immediately after the generator starts (do not long press to avoid damaging the starter motor).

Check after startup: After the generator is started, the remote control indicator light will flash, and the data center will display voltage and frequency. Observe that the engine runs smoothly without any abnormal noise.

Cold machine regulation: If the cold machine is started, the generator may run at high speed and wait for 3-5 minutes for the speed to stabilize (automatic regulation).

(2) Electric start (used when there is no remote control or when the remote control fails)

Preprocessing: Same as remote control startup, ensure that all switch positions are correct and the load is disconnected.

Start operation: Press the "START/STOP" button on the control panel for 2 seconds, and release it after the engine starts; If it fails to start once, try again after a 30 second interval (to avoid overheating of the starting motor).

Fault handling: If the startup fails 3 times, check the battery level (possibly low), whether the fuel is sufficient, and whether the spark plug is normal.

(3) Hand pulled start (emergency backup, used when the battery is low)

Preprocessing: Close the air door (push in the air door knob), turn on the fuel valve, turn off the battery switch (no power supply required), and disconnect the load.

Start operation:

Press and hold the generator body with one hand (to prevent vibration displacement), and hold the starting rope handle with the other hand. Slowly pull until you feel an increase in resistance (piston compression stroke), then quickly and forcefully pull the handle.

After starting the engine, slowly return the handle (to avoid rebounding and hitting the body) and gradually open the air door (pull out).

Hot engine start: If the engine has been preheated, there is no need to close the air door, simply pull the start rope.

(4) Stable process after startup

Run without load for 3-5 minutes, allow the engine and generator to fully warm up, observe the data center: voltage 230-250V, frequency 58-62Hz, no fault indicator light on (CO alarm light, low fuel alarm light, etc. are all off).

Check engine sound: The sound is uniform during normal operation and there is no abnormal noise (such as knocking or whistling); If there is any abnormal noise, stop the machine immediately for inspection.

Load connection: According to the principle of "high power first, low power later", connect the devices one by one, ensuring that the plug is fully inserted during connection to avoid loosening and heating.

3. Monitoring and regulation during operation

Real time monitoring points:

Data center: Regularly check voltage, frequency (fluctuation range should not be too large), and cumulative operating time (remind maintenance cycle).

Indicator lights: CO alarm light, low oil alarm light, overheating alarm light, overload alarm light should all be turned off. If they are turned on, follow the fault handling process.

Fuel gauge: Observe the remaining fuel level and replenish it in a timely manner (to avoid shutting down due to running out of fuel).

Adjustment operation:

If the overload alarm (circuit breaker tripping) is caused by excessive load, immediately disconnect part of the load, press the circuit breaker reset button, and then reconnect.

If the engine speed fluctuates during operation, it may be due to insufficient fuel supply or clogged air filter. Check if the fuel valve is fully open and if the air filter is clean.

Long term operation (exceeding 2 hours) requires regular checks of engine temperature (with no abnormal overheating on the side of the body) to ensure good heat dissipation.

4. Shutdown process (operating in different scenarios)

(1) Normal shutdown

Disconnect all loads (unplug or turn off the device switch).

Run the generator without load for 3-5 minutes to cool down the engine and generator (to avoid direct shutdown due to high temperatures causing carbon buildup).

Press the "START/STOP" button on the control panel for 1 second or the "STOP" button on the remote control to shut down the engine.

Turn off the battery switch (OFF) and fuel valve (OFF).

Close all waterproof covers of sockets and cover with dust covers (if not used for a short period of time).

(2) Emergency shutdown (fire, leakage, abnormal noise, etc.)

Press and hold the "START/STOP" button on the control panel for 3 seconds to force a shutdown (without disconnecting the load).

Follow up processing: Investigate the cause of the malfunction (such as fuel leakage, engine noise), eliminate the fault before use, and prohibit restarting without troubleshooting.

(3) Long term shutdown (exceeding 1 month)

Disconnect the load according to the normal shutdown process and run it without load for 1 minute.

Close the fuel valve and allow the engine to continue running until the fuel runs out and automatically shuts down (to avoid fuel deterioration and blockage in the carburetor).

Disconnect the battery connection (unplug the quick connector), fully charge the battery and store it separately (to avoid damage due to low battery).

Clean the dust and oil stains on the surface of the generator, check the condition of the air filter and spark plug, and clean them if necessary.

Inject 1 teaspoon of new engine oil into the cylinder and pull the starting rope 3-5 times (without ignition) to evenly distribute the oil on the cylinder wall (rust prevention).

Cover with a dust cover and store in a dry, ventilated, and cool room (do not store in flammable areas).

Complete maintenance process (including cycle and details)

1. Preparation before maintenance

Safety measures: Turn off the generator, disconnect the battery connection, and allow the engine to cool to room temperature (to avoid high-temperature burns); Operate in a well ventilated area and prepare tools (wrench, oil pan, funnel, wire brush, etc.).

Tool list: Phillips/Phillips screwdriver, spark plug socket wrench, oil pan, funnel, cleaning cloth, compressed air (optional), new oil, fuel stabilizer, spark plug (spare), air filter cleaning fluid.

2. Routine maintenance items (executed on a periodic basis)

Before/after each use

Cleaning: Use a dry cloth to wipe the dust and oil stains on the surface of the machine body, clean the debris on the heat sink and ventilation openings (to avoid blockage that affects heat dissipation); Check if the waterproof cover of the socket is intact.

Check:

Appearance: The components are not loose or damaged, and the oil pipes and oil pipe joints are not leaking.

Oil level: The engine oil level is between "L" and "H", the fuel gauge shows sufficient, and there is no leakage.

Battery: The connection is firm, without bulging or leakage (lead-acid batteries need to check the electrolyte level, and if it is insufficient, add distilled water).

Cable and plug: No damage or aging, and the plug has good contact.

Run every 8 hours (or after each use)

Oil level check: Add oil to the standard level (not exceeding the "H" mark).

Fuel filter inspection: Observe whether there is moisture or impurities in the sedimentation cup. If there are, unscrew the drain screw to drain it, and then tighten it again.

3. Long term storage and maintenance (over 3 months)

Preparation before storage:

Cleaning: Thoroughly wipe off dust and oil stains on the surface of the body, clean up debris from the heat sink and ventilation vents.

Fuel treatment:

Method 1 (Adding Stabilizer): Fill up with fresh fuel, add fuel stabilizer (according to the instructions), start the engine and run for 5 minutes, let the stabilizer circulate to the fuel system, and close the fuel valve and battery switch.

Method 2 (Drain Fuel): Close the fuel valve, unscrew the carburetor float drain screw, and drain the fuel; Unscrew the fuel tank drain screw, drain the fuel from the tank, and then tighten all screws.

Oil change: Change the engine oil according to the procedure (to avoid impurities in the old oil corroding the engine).

Cylinder rust prevention: Remove the spark plug, inject 1 teaspoon of new engine oil into the cylinder, pull the starting rope 3-5 times (without ignition) to evenly distribute the engine oil on the cylinder wall, then reinstall the spark plug and pull the starting rope until the piston is in compression stroke (valve closed to prevent moisture from entering).

Battery handling: Disconnect the battery, store it separately after fully charging, and recharge it every 1-2 months (to avoid battery depletion).

After storage, remove and use:

Remove the dust cover and check the appearance of the generator for any damage or debris.

Connect the battery and check the oil level (replenish if insufficient).

Add fresh fuel (do not use fuel that has been stored for too long).

According to the normal start-up process, the engine may emit smoke for a short period of time (residual oil in the cylinder), which is a normal phenomenon and will disappear after running for 1 minute.

4. Maintain taboos and precautions

Do not use flammable solvents such as fuel or banana oil to clean components (such as air filters and machine bodies) to avoid causing fires.

It is prohibited to mix different brands and models of engine oil, and it is forbidden to use two-stroke engine oil or inferior engine oil (which can damage the engine).

When replacing spark plugs, the recommended model must be used and the tightening torque should not be too high (to avoid damaging the cylinder head threads).

When cleaning the air filter, do not twist or tear the foam filter element, and do not wash the paper primary filter with water (only air blowing).

After all maintenance operations, it is necessary to ensure that the components are securely installed and the screws are tightened to avoid detachment during operation.
