Recommendations for the Use and Maintenance of Electric Generators

When we do not have access to the public electricity network, having an autonomous source of energy is essential.

Electric generators are an excellent element for emergencies or power shortages. Here we offer you a guide so you can choose the best option for you.

How to use an electric generator?

Fill with oil to the level recommended by the manufacturer. If you have a lower level, it may be the case that it does not work correctly or does not work at all. You must use the type of oil indicated in the instructions.

Open the fuel tap and fill with the necessary amount. If the gasoline has an oil mixture (in 2-stroke engines), make the appropriate proportion.

If the generators start automatically, check that you have the battery connected. If it is a manual start, pull the rope several times, in a short movement until the engine starts.

Where to use electric generators?

Regardless of how the generator is going to be used, you need to define where it’s going to be installed; indoor, outdoor, or you plan to install a generator on roof, since its correct operation and that it does not suffer deterioration will depend on that.

It must be in a fully ventilated place, preferably in a covered place but always outside. Engine fumes are toxic if they accumulate in a room.

It is also important that you always place it on a stable floor. If it is going to be fixed in one place, on a terrace or patio, for example, you can make a small floor to avoid unnecessary vibrations. It must also be protected from direct sunlight.

Both gasoline and diesel generators have a variety of uses:

  • In agribusiness they are used in pumping and support stations to dry seeds;
  • They are used commercially as an alternative energy source in case of blackouts;
  • In a house they are necessary in the face of any lack of electricity supply, because they supply the basic needs of lighting, ventilation, cooling, etc.;
  • In construction, it facilitates the work of extracting air, supporting motor pumps and automating certain processes.

Generator use tips

  • Be sure to turn off the power before setting up the generator, and unplug any connected appliances;
  • Run the generator outside and as far away from structures as possible. Never turn it on indoors;
  • Do not expose the generators to moisture, rain or snow, because electric shocks or short circuits may occur during use;
  • Do not overload the generator, since an extra load will damage the appliances and can cause a fire;
  • Turn off the generator and let it cool down before refueling it. Do not spill fuel on a hot generator, as this will cause a large explosion;
  • To reduce the high noise produced by the diesel generator, it incorporates a soundproof hood with noise levels of 68 to 72 DB(A) at 7 meters;
  • The generator must be grounded to prevent electrical equipment powered from causing electric shock.

Generator maintenance tips

Due to its construction characteristics, there are generators that operate at speeds of 3,000 rpm and others at 1,500 rpm (revolutions per minute). The former should not be operated in continuous cycles of more than five hours, as they require rest intervals of at least 45 minutes. 

On the other hand, equipment that operates at 1,500 rpm allows longer periods of continuous use.

The maintenance of the generators of 3,000 rpm must be carried out every 150 – 200 hours. Meanwhile, for those that work at 1,500 rpm, they can operate up to 1,300 – 2,000 hours before requiring maintenance.

After 20 hours of operation, it is necessary to renew the oil. If you are going to store the generator for a long time, you should remove any remaining gasoline, as it loses quality over time. Store it in a dry place, protect it from the sun and cover it, especially in dusty environments.
