Commercial Diesel Generator Set Maintenance Checklist

Sep. 24, 2021

The maintenance of diesel generator sets is an important part that cannot be ignored. If this process is ignored, the performance of diesel generator sets will be seriously affected. In order to allow users to quickly, safely and simply understand the maintenance of diesel generator sets, Jiangsu Starlight Electricity Equipments Co.,Ltd. has compiled the following maintenance list of commercial diesel generator sets for you.


1. Daily inspection of diesel engine.

Ideally, a professional maintenance technician should monitor the generator while it is running. If not, check whether the exhaust, fuel and electrical systems are abnormal. Also, listen to the crackling noise of the engine. In addition, pay attention to oil leakage and clean up on site. Note that the valves, hoses and belts are loose for tightening. Motor vibration can also cause screws, nuts, and bolts to loosen. After spotting insects and their nests, clean them up. Protect your generator, let it run smoothly and reduce damage.


2. Detect the oil level.

Be sure to turn off the generator before checking the oil. It is a basic maintenance process that only takes a few minutes. Insert a dipstick in the fuel tank, check the indicator, and determine the oil level. If the oil change is normal, you must empty the container before adding new oil. According to the maintenance manual, you must always use the oil brand recommended by the manufacturer, and not frequently change the oil brand.


3. Avoid overheating of the generator.

Overheating is one of the most common problems of depletion of generator life. This will not only damage its operation, but may also bring security risks. Therefore, check the coolant level after turning off the generator. Next, cool the engine. If your generator overheats, add enough coolant, but don't fill up the water tank. Use a soft clean cloth to clean the radiator to remove dust on the radiator. Jiangsu Starlight Company also recommends using a hot air gun to check the temperature and check the leakage of the coolant.

4. Commercial diesel generator fuel inspection.

The ventilation of the diesel generator set area is better. But too much or too little ventilation will lead to carbon deposits and insufficient fuel. There is also a danger of condensation in the engine. Therefore, the fuel filter must be cleaned frequently. It can be replaced if necessary. Diesel fuel will be consumed within a year. So, can't store fuel for a long time? If the fuel injection system does not work properly, an additional fuel filter device may be required.


5. Battery testing.

The battery of the diesel engine is used to start the engine. Most system failures are due to battery overuse or undercharge. You must check the health of the battery regularly. Specifically, you have to check the gravity and electrolyte levels, and solve this problem before damaging the generator. Other than the detection output voltage. Old batteries are extremely resistant to electric current. Therefore, in order to obtain an accurate voltage measurement, it is necessary to perform detection under load. To do this, you may need a battery load test accessory.


The battery should always be kept clean and oil-free to avoid malfunction due to corrosion.

To clean the battery, wipe it with a damp cloth. If there is corrosion around the junction box, please remove the battery cable first. Wash with a small amount of soda and water mixture.


6. Engine exhaust detection.

When the generator is running, check the entire exhaust system. Check exhaust pipes, silencers and pipelines. Signs that need to be inspected include leaks, loose welds, gaskets, and joints. In addition, make sure that the pipes entering and exiting the exhaust pipe will not overheat. When the exhaust system is not working properly, the generator will consume more oxygen. So the fuel will run out soon.
