ESSENTIAL SAFETY MEASURES FOR YOUR SUMEC FIRMAN GENERATOR

Your generator is an electrical device that converts mechanical energy to electrical power for use in an external circuit. It is necessary to take appropriate safety steps to ensure your generator serves you for a long time.


It is essential to protect your generator  from damage to keep it running smoothly for longer, increase efficiency and save you more money by avoiding unnecessary repairs. We'll discuss nine(9) safety preventive measures when caring for your generator.

Safety Measures

  • Avoid moisture coming in contact with your generator.

Do not expose your generator to wet conditions like rain or wash your generator with water, and do not operate your device with wet hands as this can cause electric shock .

  • Always refuel or change the oil in your generator only after the generator has cooled down.

Please turn off your generator and allow it to cool down completely before you refuel or change the oil.

  • Don't overload your generator.

Avoid plugging too many electrical appliances that carry much more power than your generator can provide. Also, ensure you know your generator's kilovolt-Ampere(kVA) knowing how much energy it can provide. You can learn more about loading your generator properly by reviewing our other blog posts.

  • Don't position your generator very close to a wall.

Keeping your generator too close to a wall can cause overheating, decreasing its life span. It can prevent the smoke from leaving your generator, trapping it inside the machine and causing the engine oil to turn black and release soot which will, in turn, affect the carburettor.

  • Ensure you use good quality petrol or diesel for your generator.

Do not use old or contaminated petrol or diesel for your generator; ensure you get quality fuel for your generator. Purchasing fuel treatment is advisable; this will help prevent unrefined petrol/diesel from damaging your generator.

  • Ensure you use recommended engine oil for your generator.

Seek professional help from your generator engineer for recommendations. However, the most recommended engine oil for any generator is Firman engine oil, and if you cannot find one, the next best choice is Mobil 1 engine oil. Ensure you change your oil every two weeks; this will help your engine be cool and prevent overheating.

  • Employ only good quality technicians for your generator.

Once you have a sound technician for your generator, stick to that one technician so that they can monitor the progress and regress of your generator; and avoid constant changing of your technician. A wrong technician can be the main difference between having a good experience with your generator and a horrible experience with the same generator.
