A diesel generator is often very costly, which may be a headache for you. If your initial investment is low, you must buy a generator, which is already used. However, before you proceed further, you must know how to recognize the machine at the initial stage.
You must see the make as well as the model of the machine, which you want to purchase. The information will be available from the manufacturer website. You must be aware with the technical specifications of the new model in order to compare the same with the used one. This comparison is essential for knowing your expectations from a diesel generator. You can also search in the internet to know about the performance details of the machinery.
You need to gather information regarding the nature of its use from the earlier user. This includes the maximum load it can withstand and the duration in hours it can run. For an ideal generator, lesser number of operating hours and better peak load enable the performance of the machine. Lesser hours of operation reduce the wear and tear of the machine. The performance of the generator at the peak of its rated power has to be remembered if you are purchasing a used generator in order to support the blackout period. On such cases, the entire electrical load of your building is borne by the generator.
You must receive the load test certificate from the reseller, which is very important. Many a times the reseller does not agree to give the certificate, which is not a part of honesty. In such cases, you must take the help of other resellers in order to purchase used diesel generators. It is important to know the total load test, as that is the parameter, which determines the overall performance of the diesel generator. Special eye of inspection must be on the engine parts, rotor, and stator, and peak load performance, exhaust as well as fuel efficiency. Just as acid test is done to test a sample whether it is an acid or base, the same is the case with the load test. So, load test is regarded as the acid test for Used Diesel Generators. You can also ask the reseller to rebuild the engine to increase its performance. This is one of the most advisable technique you can apply to increase the performance of the machine.
