Hey there! As a gas generator supplier, I often get asked about what to do when a gas generator has been stored for a long time. It's a common situation, especially if you've got a backup generator that sits idle for months or even years. In this blog, I'll share some tips on how to get your long - stored gas generator up and running again.
1. Pre - inspection
First things first, before you even think about starting the generator, you need to give it a good look - over. Check for any obvious signs of damage, like cracks in the casing, loose wires, or rust. Rust can be a real problem as it can affect the performance and longevity of the generator. If you see any rust, you'll need to clean it off carefully. You can use a wire brush to remove the loose rust and then apply a rust inhibitor to prevent further corrosion.
Take a look at the fuel system. Over time, fuel can break down and leave behind deposits that can clog the fuel lines and carburetor. If you notice any signs of fuel leakage, that's a serious issue. You'll need to fix the leak before you attempt to start the generator. Also, check the fuel filter. A clogged fuel filter can starve the engine of fuel, preventing it from starting.
2. Fuel System Maintenance
The fuel system is one of the most critical parts of a gas generator. If the generator has been stored for a long time, the fuel might have gone bad. Gasoline can start to break down after just a few months, especially if it's not treated with a fuel stabilizer.
If you think the fuel is bad, drain it completely. You can do this by opening the fuel drain valve. Once the old fuel is out, fill the tank with fresh, clean gasoline. It's also a good idea to add a fuel stabilizer to the new fuel. This will help prevent the fuel from breaking down again during future storage.
The carburetor is another important part of the fuel system. Over time, deposits can build up inside the carburetor, causing it to malfunction. You can clean the carburetor using a carburetor cleaner. Remove the carburetor from the engine and follow the instructions on the cleaner to clean all the internal passages.
3. Oil and Lubrication
The oil in your generator is like the blood in your body. It lubricates the engine parts, reduces friction, and helps keep the engine cool. If the generator has been stored for a long time, the oil might have degraded.
Check the oil level in the engine. If it's low, add the appropriate type of oil as recommended by the manufacturer. It's also a good idea to change the oil and the oil filter. Old oil can contain contaminants that can damage the engine over time.
4. Spark Plug Check
The spark plug is responsible for igniting the fuel - air mixture in the engine. If the spark plug is dirty or worn out, the engine might not start. Remove the spark plug and inspect it. If it's covered in carbon deposits, you can clean it using a wire brush. If it's severely worn, replace it with a new one. A good spark plug is essential for the proper functioning of the generator.
5. Battery (if applicable)
Many modern gas generators come with a battery to start the engine. If your generator has a battery, check its condition. Over time, a battery can lose its charge. You can use a battery charger to recharge the battery. If the battery is old and won't hold a charge, it's time to replace it. A dead battery can prevent the generator from starting, so it's important to keep it in good condition.
6. Testing the Generator
Once you've completed all the maintenance steps, it's time to test the generator. Make sure the generator is in a well - ventilated area, away from any flammable materials. Turn on the fuel valve, set the choke (if necessary), and try to start the generator. It might take a few tries, especially if it's been sitting for a long time.
If the generator starts, let it run for a few minutes to warm up. Check for any unusual noises or vibrations. If everything seems okay, you can connect a small load, like a light bulb, to test the output. Make sure the voltage and frequency are within the acceptable range.
