Fuel emission hose: located at the bottom of the left side of the aircraft, used to drain the fuel from the tank (such as during long-term storage or when the fuel deteriorates).

Safety operation rules (including risk avoidance)
1. Environmental safety requirements
The operating position should meet the following requirements: good outdoor ventilation, away from doors, windows, ventilation openings, tents, etc. (to prevent the accumulation of carbon monoxide); The ground is flat and hard (to avoid vibration and tilting during operation, which may cause fuel/oil leakage); Maintain a distance of at least 1.8m from combustible materials such as wood, hay, paint, etc., and maintain a heat dissipation space of at least 0.5m from other equipment.
Prohibited from use in the following scenarios: confined spaces (indoor, garage, basement), damp ground (waterlogged, muddy), thunderstorm weather, and high dust concentration environments (such as construction site dust areas).
Extreme environmental response: When operating at high temperatures (>35 ℃), it is necessary to operate in a cool place and avoid direct sunlight; When the temperature is low (<0 ℃), winter specific engine oil (such as 5W-30) should be used, and the engine block can be preheated before starting (to avoid open flame heating).
2. Fuel safety operation
Preparation before refueling: Turn off the engine and wait for at least 10 minutes for it to cool down (the muffler temperature can reach over 400 ℃, which can easily ignite the fuel); Clean the oil around the fuel filler to prevent impurities from entering the fuel tank.
Refueling operation: Use a dedicated refueling pot to slowly refuel, with the oil level not exceeding the red limit ring in the fuel tank (reserve 5-10% expansion space); If fuel spills, immediately wipe it clean with a dry cloth and wait for it to evaporate before starting the engine.
Fuel storage: Backup fuel should be stored in a qualified fuel container, in a ventilated, cool, and away from sources of fire, for a period of no more than 3 months (with the addition of fuel stabilizers, it can be extended to 6 months).
Forbidden operation: Do not refuel while the engine is running; Prohibit using fuel to clean equipment; Do not place fuel containers on the generator or near heat sources.
3. Electricity safety regulations
Extension cable selection: 240V AC extension cables must comply with AS/NZS 3199:2007 standards, using 15A heavy-duty three core cables (core cross-sectional area ≥ 1.5mm ²), with a length not exceeding 25m (1.5mm ²) or 40m (2.5mm ²); The length of the 12V DC extension cable shall not exceed 3.5m, and the cross-sectional area of the wire core shall be ≥ 1.0mm ².
Load calculation method:
Pure resistance load (light bulb, heater, rice cooker): starting power=operating power, total operating power ≤ 2100W.
Inductive loads (air conditioning, water pump, motor): starting power=operating power x 1.2 (small portable equipment) or 3.5 (large fixed equipment), total starting power ≤ 2400W.
Example: 1.5kW air conditioner (operating power 1500W), starting power=1500 × 3.5=5250W>2400W, cannot be driven separately; 0.8kW water pump (operating power 800W), starting power=800 × 1.2=960W, can be driven.
Grounding requirements: The generator itself has an equipotential connection system and does not require separate grounding; If connecting fixed equipment or using in humid environments, a certified electrician must connect the grounding terminal to the grounding electrode (such as a metal grounding rod).
Emergency response: In case of equipment tripping, heating, or odor during power consumption, immediately disconnect the load, shut down the generator, and troubleshoot before use.
4. Personnel safety protection
Wear goggles (to prevent fuel splashes and debris from entering the eyes) and gloves (to prevent oil contamination and burns) during operation; Long hair should be curled up to avoid getting caught up in moving parts.
Children and pets are prohibited from entering within a 1m radius of the generator; Operators need to be familiar with the operating procedures and avoid operating under the influence of alcohol or fatigue.
Emergency situation handling: In case of fuel leakage, immediately stop operation, stay away from the scene, and clean up after the fuel evaporates; If a fire occurs, use ABE or BE type fire extinguishers to extinguish it (it is prohibited to directly extinguish electrical fires with water); If you feel dizzy or nauseous after inhaling carbon monoxide, immediately transfer to a well ventilated area and seek medical attention in severe cases.
Step by step operation guide (including key details)
1. Preparation for the first use of the new machine
Open the box inspection: Open the packaging and take out the generator and accessories (400mL SAE 15W-40 engine oil, fuel can, screwdriver, spark plug socket wrench, dust cover, instruction manual); Check that the appearance of the generator is undamaged, the components are not loose, and the sockets and switches are functioning properly.
Oil filling:
Place the generator on a level surface and open the left oil maintenance cover.
