Core functions and operation guide

1. Core functional features

Dual fuel switching: The control panel is equipped with a fuel selection switch, which supports switching during operation (propane cylinders need to be connected in advance). During switching, the engine may briefly become unstable, which is a normal phenomenon.

Startup method:

Remote start: Use the matching keychain remote control with an effective distance of 30 meters and a 2-cell CR2016 battery model.

Electric start: First, turn on the battery switch and press the start button on the control panel.

Hand pulled start: Suitable for when the battery is low, slowly pull the rope until there is resistance and then quickly pull it.

ECO mode: After being turned on, the engine speed automatically adjusts with the load, reducing fuel consumption and noise, suitable for low-power continuous loads (such as lamps and computers); It is recommended to turn off ECO mode for high-power devices such as air conditioning and water pumps.

safeguard:

CO sensor: monitors the concentration of carbon monoxide in the surrounding area, automatically shuts down when it exceeds the standard, and the red indicator light flashes to give an alarm.

Low oil protection: When the oil level is below the safe value, it will automatically shut down and light up the low oil indicator light.

Overload protection: When the load exceeds the rated power, the circuit breaker trips, the overload indicator light lights up, and a power-off reset is required.

Output configuration: The control panel includes a 20A dual socket (NEMA 5-20R), a 30A RV dedicated socket (NEMA TT-30R), two 5V/2.1A USB interfaces, and supports parallel operation interfaces (requiring dedicated parallel wires).

2. Key operational steps

(1) First use preparation

Add engine oil: The new machine has no engine oil and needs to be filled with the recommended 10W-30 engine oil to the L-H mark on the dipstick. Overfilling is prohibited.

Connecting fuel:

Gasoline: Open the fuel tank cap and add 87-93 gasoline to the red filling ring in the tank. Do not overfill and tighten the fuel tank cap.

Propane: Connect one end of the matching hose to the propane interface of the generator (manually tighten, no need for raw material tape), and the other end to a gas cylinder. Use soapy water to check if the interface leaks (if it bubbles, it is a leak and needs to be re tightened).

Connect the battery: Open the battery compartment cover, connect the quick connector, and ensure that the battery is securely fixed.

(2) Start operation

Gasoline mode: Turn the fuel selection switch to gasoline mode → open the fuel tank valve → press the start button (or remote start, manual start) → wait for the output ready indicator light (green) to light up, then connect the load.

Propane mode: Turn the fuel selection switch to propane mode → fully open the cylinder valve → press the start button → connect the load after the output is ready.

(3) Shutdown and fuel switching

Normal shutdown: First disconnect all loads → let the generator run without load for a few minutes → press the stop button (or turn off the battery switch) → in propane mode, the gas cylinder valve needs to be closed.

Fuel switching (in operation):

Gasoline propane cutting: Open the cylinder valve → switch the fuel switch to propane mode → close the fuel tank valve.

Propane to gasoline: Open the fuel tank valve → switch the fuel switch to gasoline mode → close the cylinder valve.

Installation and usage specifications

1. Installation and placement requirements

It must be used outdoors with good ventilation, at least 5 feet (about 1.5 meters) away from doors, windows, and ventilation openings. It is prohibited to use it indoors, in garages, basements, and other enclosed spaces to prevent carbon monoxide poisoning.

Place on a dry, flat, hard surface to avoid sand, grass debris, and other debris blocking the heat dissipation outlet. Leave a ventilation space of 5 feet (about 1.5 meters) around it.

Grounding requirements: If connecting to the building power supply system, a professional electrician must install a conversion switch and ground it; When only using a socket for power supply, there is no need for additional grounding (neutral line floating design).

2. Extension cords and load usage

Extension cables should use outdoor dedicated and grounded 3-core wires, with wire diameter specifications that match the load and length (recommended wire diameter ≥ 12AWG and length ≤ 50 feet for 20A loads).

Load management: All loads need to be disconnected during startup, and connected sequentially after startup. First, connect high-power devices (such as refrigerators and air conditioners), and then connect low-power devices to avoid overloading caused by starting multiple high-power devices at the same time.

Power adaptation: The total operating power should be ≤ rated power, and the starting power should be ≤ peak power (for example, if the starting power of a 1/3 horsepower water pump is about 2000W, sufficient margin should be reserved).

3. Parallel operation (parallel wires need to be purchased separately)

Only compatible Westinghouse variable frequency generators can be connected in parallel, with a total rated power of up to 7400W (dual engine gasoline mode).

Operation steps: Turn off two generators → Connect parallel wires (black to black interface, red to red interface, green grounding wire) → Start two generators in sequence → Connect the load after the output is ready, and prohibit parallel connection in ECO mode.

Maintenance and upkeep

Clean the Mars extinguisher every 100 hours or 6 months. Remove the muffler cover, clean the carbon buildup on the filter screen, and replace it if it is damaged

When the battery is not used for a long time, it should be charged for 8 hours per month using the matching charger (no more than 8 hours to avoid overcharging)

2. Storage specifications

Short term storage (within 1 month): No special handling is required. Close the fuel valve and place it in a dry and ventilated place, covered with a dust cover (plastic cover is prohibited to avoid moisture).

Mid term storage (2-6 months): Add fresh fuel and fuel stabilizer, empty the carburetor float chamber of fuel, and disconnect the battery connector.

Long term storage (more than 6 months): Drain the fuel tank and carburetor, inject a small amount of engine oil into the cylinder, pull the pull rope to put the piston in the compression stroke (close the valve), disconnect the battery, and store in a dry and ventilated place.

Safety precautions

1. Core security warning

Risk of carbon monoxide poisoning: Only for outdoor use, keep away from doors, windows, and ventilation openings. Install a carbon monoxide alarm at home. If symptoms such as dizziness and nausea occur, immediately move to fresh air and seek medical attention.

Fire and explosion risks: Smoking and staying away from open flames are prohibited when refueling. Contact with mufflers (high temperature) is prohibited when heating up. Propane cylinders should be placed upright on the ground, away from heat sources and direct sunlight.

Electric shock risk: Do not use in damp environments or rainy days. Do not touch the socket when your hands are wet. The equipment should be placed in a dry place to avoid water accumulation.

2. Fuel safety

Gasoline storage: Use approved gasoline containers, store in a well ventilated area, away from sources of ignition, and prohibit long-term storage in the generator fuel tank.

Propane use: Check that the hose is not damaged or bent, close the cylinder valve after use, disconnect the hose during transportation, and fix the cylinder upright.

Troubleshooting

Unable to start without engine oil, fuel not turned on, spark plug wet/carbon deposits. Add engine oil, open fuel valve, dry or replace spark plug

Immediately stop the machine after starting, low oil, CO sensor alarm, overload and replenish oil, move to a ventilated area, and disconnect the overload load

No output power circuit breaker tripping, excessive load, socket fault resetting circuit breaker, reducing load, checking socket connection

Unstable operation, fuel impurities, clogged air filter, insufficient propane pressure. Replace with fresh fuel, clean air filter, and check propane cylinder pressure
