I. Safety Practice
1. Fuel storage and use safety
Storage environment: LPG is a flammable and explosive gas, it should be stored in a special area which is well ventilated, cool and dry, and far away from fire source, high temperature (such as heater, direct sunlight) and electrical equipment. The storage containers need to meet the national standards, and the valves and pipelines should be checked regularly for gas leakage (can be tested by applying soapy water, bubbling means gas leakage).
Fuel quality: Use LPG with high purity and low impurities to avoid clogging the nozzle or damaging the engine with poor quality fuel.
Filling operation: make sure to stop the engine and close the valve when filling fuel, it is strictly prohibited to add fuel during operation; smoking, using open flame or electronic devices such as mobile phone are prohibited during filling process.
2. Installation requirements of the set
Installation location:
The unit should be installed in a well-ventilated outdoor area (such as a terrace or courtyard), and it is strictly prohibited to use it indoors, in a garage or in a closed space, in order to prevent LPG from leaking and causing an explosion or carbon monoxide poisoning.
Keep away from doors, windows and air inlets to avoid exhaust gas backflow into the room; keep a distance of at least 1 metre from the building, and no flammable materials (e.g. weeds, paper) in the vicinity.
Fixing and ventilation: the unit should be fixed on a horizontal, solid ground (such as a concrete platform) to avoid vibration and displacement; if it is installed under a sunshade, make sure that the shed is well ventilated to dissipate heat smoothly.
3. Start-up and operation safety
Check before starting:
Confirm that the fuel valve is open and there is no leakage in the pipeline; check whether the oil and coolant level is normal (add according to the instruction manual).
Clean up the debris around the unit and make sure the cooling fan is not blocked.
Start-up operation:
Open the fuel valve first, then turn on the power to start the unit, avoid idling for too long (no more than 10 seconds).
Observe whether the instrument parameters (e.g. voltage, frequency, oil pressure) are normal after starting, and listen for abnormal noise.
Supervision during operation:
Strictly prohibit touching the high temperature parts (e.g. exhaust pipe, radiator) when the unit is running to avoid burns.
Make regular inspections to check whether there is any air leakage in the fuel pipeline and interface, and stop the machine immediately for maintenance if any abnormality is found.
Shutdown operation:
Close the fuel valve first, wait for the unit to idle for 2-3 minutes to consume the residual fuel, and then cut off the power to shut down.
Close all the valves after shutdown, and take dust-proof measures (e.g. cover the protective cover).
Maintenance of equipment
1. Regular inspection and maintenance
Daily inspection:
Check the sealing of fuel pipes and valves before each use, and clean dust and debris on the surface of the unit.
Check whether the spark plug and air filter are carbon or clogged, clean or replace them in time (refer to the manual cycle).
Regular maintenance:
Oil replacement: replace the oil after the first 50 hours of operation of the new unit, and every 200-300 hours thereafter (adjusted according to the frequency of use), using lubricating oil that meets the specifications (e.g. SAE 10W-30).
Filter replacement: replace the air filter every 500 hours or annually (dusty environment needs to shorten the cycle); replace the fuel filter every 1,000 hours to prevent impurities from damaging the nozzle.
Battery maintenance: If the unit is equipped with a starter battery, check the power regularly, clean the electrode stake to avoid corrosion; when not in use for a long time, disconnect the negative electrode or take out the battery for storage.
2. Troubleshooting and maintenance
If the unit has problems such as starting difficulty, insufficient power, abnormal noise or oil and gas leakage, stop the machine immediately and contact professional technicians for overhauling, do not disassemble the high-pressure parts or gas system by yourself.
Have the gas system (e.g. pressure reducing valve, nozzle) pressure tested and sealing checked by professional personnel regularly to ensure compliance with safety standards.
III. Environment and Emergency Management
1. Environmental adaptability
Temperature range: The LPG set is suitable for operation in - 10℃~40℃ environment, and protective measures (e.g. installing heat preservation cover or cooling fan) are required in case of extreme high or low temperature.
Rainproof and moisture-proof: the unit needs to be equipped with waterproof shell or installed in a rainproof location to avoid rainwater entering the electrical parts and causing short circuit.
2. Emergency measures
Leakage: If LPG leakage is found, close the valve immediately, evacuate people in the neighbourhood, strictly prohibit switching on and off electrical appliances or using open flame, open doors and windows to ventilate the area, and check the leakage point after the gas is dispersed.
Fire response: dry powder fire extinguishers or carbon dioxide fire extinguishers should be equipped near the unit, and it is strictly prohibited to use water to extinguish the fuel fire; if the fire gets out of control, immediately call the fire alarm and stay away from the scene.
Poisoning prevention: Although LPG itself is colourless and odourless, commercial fuels are usually added with odouring agents (e.g. ethanethiol). If you smell an abnormal odour, you need to be alert to the leakage and deal with it in time, so as to avoid carbon monoxide poisoning (CO will be generated when the unit is in operation, so you need to ensure ventilation).
IV. Standardised Management and Usage Habits
1. Operation training
The operator should be familiar with the content of the manual, and master the starting, stopping, fault reporting, and the operation of the unit.
