Many generators sit for long without being used. This can cause many problems that can result in costly repairs. This article discusses some maintenance practices that can help you to prevent your backup generator from malfunctioning.

Run It Dry

Fuel has a finite duration after which it starts breaking down. That decomposition process can cause the formation of a gel-like substance that can clog the fuel system of your generator. Once that happens, the carburetor and other engine components can fail. You can prevent this problem from happening by turning off the fuel valve when your generator is still operating. This will make the generator to stall after using up all the fuel that was within the fuel delivery system. Consequently, you will store your generator when there is no fuel inside the engine or carburetor. This will save it from the damage of degraded fuel.

Use a Stabiliser

Buy a fuel stabiliser from a fuel station and add it into the fuel in your backup generator's tank. That additive will extend the shelf life of that fuel for the duration that is stated by the manufacturer of that stabiliser. Take note of the added shelf life of that fuel so that you drain it from the generator once it reaches that expected duration.

Regular Running

Another danger of generators that sit for long without being used is that internal parts can start corroding. This is because the lubricant inside the engine eventually becomes stuck around the bearings. The best way to prevent this problem is to run the generator regularly (every three months, for example). This enables the lubricant to circulate within the engine parts so that they are protected from corrosion. It is also a good idea to let the generator run until its engine reaches the temperature at which it normally operates with a full load. This step is necessary because some water is formed as the generator burns fuel. That water can remain inside the combustion chamber if you turn off the generator before it is warm. A warm generator will cause that condensed moisture to evaporate and exit the generator through the exhaust vent.

Use the steps above to keep your generator free from defects when it is not being used. You can also ask a generator repair technician for more tips after he or she has performed a routine inspection of your generator. This will keep the generator in an excellent condition for a long time.
