Proper, timely, and careful maintenance of diesel generator sets is the most effective way to ensure normal operation, reduce wear and tear, and prevent malfunctions. There are many types of generator maintenance, and it should always be carried out by emergency power supply equipment suppliers. Below we list the maintenance service component inspections and regular annual maintenance required for proper maintenance of the generator.

A. Parts inspection

Perform component inspections to ensure that generator components and reservoirs are prepared for power outages. For regularly maintained generators, the cost of these inspections is relatively low.

They include the following services:

1. Test the output voltage at the transfer switch to see if the generator is working properly

2. Transfer switch test to ensure normal switch function

3. Maintenance of transfer switches, if the building's power supply can be disconnected

4. Test water level, pressure, and status of generator oil

5. Check the level and condition of the generator coolant

6. Check the temperature at each position of the generator cooling circuit

7. Check the function and temperature of the heating block

8. Check basic equipment such as pumps and belts

9. Check that the lights on the generator and transfer switch of the indicator light up

10. Test the panel instruments on the generator and transfer switch

11. Test the condition of the battery, battery cables, and charger

12. Testing for liquid leakage

13. Oil level test

B. Annual maintenance

1. Oil replacement

2. Replace the old oil filter

3. Replace the old fuel filter

4. Replace the old coolant filter

5. Replace the old air filter

6. Re oil the oil bath air filter

7. Replace the conversion switch battery

8. Add fuel additives to maintain fuel quality

9. Add coolant additives to maintain the coolant circuit
