First Level Maintenance Inspection of Standby Generator

Diesel generator sets can be divided into two types according to the use situation: one is based on mains power, generator set standby power supply equipment and the other is generator-based power supply equipment. To ensure that the genset is in good condition and prolong the service life of the machine, the technical maintenance system of the diesel engine must be implemented. The technical maintenance categories are divided into:

First level maintenance inspection (daily or weekly)

Secondary maintenance inspection (every 250 hours or one month)

Level 3 maintenance inspection (every 1500 hours or half a year)

The standby generator should run regularly for about 10 minutes, so as to evaporate the water in the diesel engine body and achieve moisture and corrosion protection.

First level maintenance inspection

1. Check oil level.

Use a diesel oil dipstick to check the oil level. In order to obtain accurate readings, the oil level should be checked when the oil flow back to the oil pan after 15 minutes of shutdown. The oil level should be matched with the original oil pan, and the oil level should be kept as close as possible to the high "H" mark.

Warning: Never operate a diesel engine when the oil mark is lower than the low mark “L” or higher than the high mark “H” (if necessary, add the same quality and grade of engine oil).

2. Check cooling system

Keep the coolant filled to the working level, check the coolant level every day or every time before turning on, analyze the cause of the coolant consumption, and check the coolant level, only after the cooling system is cooled.

3. Check the connections of the intake pipe

Check the joints of the air intake pipe, whether the clamp is loose, whether the hose is cracked, perforated or worn, whether the hose is broken or other damage, tighten the clamp or replace parts as needed to ensure that the air intake system is well sealed and all air passes through the air filter.

4. Appearance inspection

Check for leaks of external air, coolant or oil. Tighten screw connections, joints, etc. or replace gaskets as needed. Check the oil pipe cover of the oil dipstick to see if it is tight.

5. Check for damage

Check the fuel system, including the incorrect adjustment or injury of the fuel pump, and check for leaks or damage at all connections.

6. Check drive belt

inspect whether the fan, water pump, and charger belt is damaged or slack, and replace the damaged buckle with a new one. And adjust the tightness, if necessary, ask a professional technician to adjust.
