When a diesel generator is not used for an extended period of time, there are certain actions that must be taken in order to ensure that the generator is in proper working condition when it is next needed. One of the first things to do is to make sure that the fuel system is empty. This can be done by running the generator until it runs out of fuel or by manually draining the fuel system.
Next, it is important to add a fuel stabilizer to the remaining fuel in the tank. This will help prevent the fuel from breaking down and becoming contaminated while the generator is not in use. It is also a good idea to change the oil and oil filter to ensure that any moisture or contaminants that may have accumulated in the oil are removed.
Another important step is to check and clean the air filter. A dirty air filter can cause the generator to run poorly and can also damage the engine. It is also important to check all the hoses, belts, and connections for signs of wear or damage.
It is also important to check the battery's charge level and to make sure that it is properly maintained. A weak battery can cause the generator to fail to start. It is also a good idea to disconnect the battery to prevent it from being drained while the generator is not in use.
Finally, it is important to cover the generator to protect it from the elements. A generator cover can help prevent damage from rain, snow, and sun exposure. It is also a good idea to place a desiccant packet inside the generator to absorb any moisture that may accumulate inside.
It is important to keep in mind that the generator should be serviced by a professional technician before it is put into operation after a long period of inactivity. This will ensure that the generator is in proper working condition and is safe to operate. A generator that has not been properly maintained can cause damage to equipment and can even be a safety hazard.
