Propane generators have become a popular choice for household emergency power supplies, camping and outdoor operations due to their advantages such as stable fuel, clean emissions and simple maintenance. However, if not used for a long time, incorrect storage methods may lead to equipment aging, component damage, and even affect performance when restarted. Therefore, proper storage and maintenance are of vital importance.
Preparations before storage
Thoroughly clean the generator
Before long-term storage, the generator must be thoroughly cleaned to prevent dust, oil stains or residual fuel from affecting the internal parts.
External cleaning: Wipe the body with a soft cloth to remove dust and oil stains. Avoid using a high-pressure water gun to prevent water from seeping into the circuit.
Internal inspection: Check key components such as the air filter and spark plugs, and replace or clean them if necessary.
Empty the fuel system
Although propane is more stable than gasoline, it is still necessary to ensure that there is no residue in the fuel system during long-term storage. Close the valve of the propane tank, disconnect the connecting pipe and let the generator naturally consume the remaining fuel. Inspect the fuel pipeline to ensure there are no signs of leakage or aging. Replace the sealing ring if necessary.
Change the engine oil
Change the engine oil before long-term storage to prevent the acidic substances in the old oil from corroding the engine interior. Run the generator for 5 minutes to thin the engine oil, making it easier to drain. After draining the old engine oil, add new engine oil to the recommended level.
Check the battery (for electric starter models)
If the generator is equipped with an electric start function, the negative terminal of the battery should be disconnected to prevent the power from running out. Check the battery power every three months. Charge it or use a battery maintainer if necessary.
Lubricate key components
Apply anti-rust lubricants to moving parts such as bearings and piston connecting rods to prevent oxidation. Check if the belt is aged and replace it if necessary.
Correct Steps for Long-term Storage
Choose an appropriate storage environment
Dry and well-ventilated: Avoid damp environments to prevent circuits from getting damp or metal parts from rusting.
Suitable temperature: The optimal storage temperature is 5°C to 30°C, avoiding extreme high or low temperatures.
Keep away from flammable materials: Even if the fuel has been drained, still stay away from fire sources or chemicals.
Correct coverage protection
Cover the generator with a dust cover or breathable fabric to prevent dust accumulation. Do not use plastic sheeting to prevent the internal moisture from not being able to evaporate, which may cause condensation water to corrode the parts.
Regular inspection
Check the storage status every 2 to 3 months to ensure there are no problems such as pests, moisture or aging of components. If stored for more than 6 months, it is recommended to start it once (run for 10 to 15 minutes) to keep the interior lubricated.
Reactivation after long-term storage
Check the fuel system
Reconnect the propane tank and check if the pipeline is aged or leaking (you can test it with soapy water). Make sure that the valve opens and closes normally and is not blocked.
Change the engine oil (as needed)
If it is stored for more than one year, it is recommended to change the engine oil again to ensure the lubrication effect.
Test startup
Manual start model: Pull the start rope and observe if it runs smoothly.
Electric start model: Check the battery power and charge it if necessary.
After startup, observe the operating status to ensure there is no abnormal noise or vibration.
Frequently Asked Questions and Answers
Q1: How long can a propane generator be stored?
Ideal storage period: Within 6 months, no special maintenance required.
For more than 6 months: It is recommended to start it once every 3 months to maintain internal lubrication.
Q2: Is it necessary to empty the propane tank when storing?
No need. Tank C has high stability, but it is necessary to ensure that the valve is closed to prevent leakage.
Q3: What should I do if it won’t start after long-term storage?
Check if the spark plugs are carbon deposits and if the fuel lines are unobstructed. Replace the parts if necessary.
Conclusion
The key to long-term storage of propane generators lies in cleaning, draining the fuel, changing the engine oil, and preventing moisture and dust. Following the maintenance steps in this article can significantly extend the service life of the equipment and ensure its immediate availability in emergency situations
