How to Properly Conduct Generator Preventive Maintenance

Electric generators

Whether it’s a commercial or residential setting, finding reliable power continuity solutions is very important in keeping operations going after power outages. Many organizations and also individuals have invested in an array of solutions for power supply continuity. A generator is one of them, and it’s one of the most effective power solutions to date. However, a generator, like any other machine, experiences wear and tear. They develop mechanical problems during operation, some of which are complex and costly to repair.

Preventative maintenance for diesel and electric generators contributes significantly to reducing repair associated costs, ensuring durability and maximizing reliability. In fact, emergency repair costs are typically high than the cost incurred in proactive maintenance. The generator’s manufacturer provides some operations you can do to ensure your machine functions properly and ready to be used when needed.

Here some of the generator preventative maintenance procedures you need to know.

General Inspection
When a generator is in operating mode, the possibility of it developing mechanical issues is very high. Some of the common problematic components in a generator include the fuel system, DC electrical system, air intake system, exhaust system, and engine. These are the areas you need to look at for leaks and any other issues which could affect the generator performance.

Lubrication service
To ensure your generator is safe and running efficiently, proper generator preventative maintenance practices are essential. For diesel generators, changing the oil is critical, especially after every 100 hours of operation. This should be done with utmost care and appropriately. Be sure to check the fuel system, particularly the fuel and water filter and separators, which have to be replaced at recommended time intervals. If it’s a gas powered generator, inspect the supply piping system for any leaks.

Cooling System
To inspect the coolant level, ensure the generator is in a shutdown mode and give the engine time to cool before you remove the radiator cap. With different types of electric generators, it’s important you understand the manufacturers manual when it comes to adding a coolant. Some high-performance diesel engines will need you to put equal measures of coolant additives, water, and antifreeze.

Check the radiator for obstructions and gently clean any dirt on its surfaces. You can choose to either use a soft brush or a low-pressure jet wash.

Fuel System
Diesel engines are exposed to impurities and corrosion after a while, hence the need for regular generator preventative maintenance. The fuel filters get filled with moisture, and therefore you need to drain them at the recommended intervals. If a generator is unused for a long period, check the fuel system, polish the fuel and inspect the oil and coolant level. In addition, watch out leaks, dirt, damages on the cooler piping system.

Other generator services you may also need to include testing and cleaning batteries, checking for electrolyte gravity and level. These maintenance activities can be done on both commercial and residential generators with the help of an expert. Lastly, having a maintenance schedule will help you to keep track of the corrective measure you’ve taken and record the observations for future reference.
