Proper maintenance is crucial for the longevity of generators. It must be performed by qualified technicians. It's important to keep records during maintenance, as this will aid in scheduling future maintenance procedures.

In summary, generators should be kept clean, ensuring no liquids such as fuel or lubricant accumulate on any surface inside or out. They should not be placed on, under, or around any sound-absorbing materials. Industrial water solutions should be used to clean the surfaces of the machine, and flammable solutions should never be used for cleaning purposes. If the protective material for sound-absorbing substances is torn or pierced, it must be replaced immediately to prevent the penetration or accumulation of liquids or oils.

Due to varying generator usage, maintenance requirements also differ. Daily maintenance and post-startup maintenance: (for backup generators), these steps can be performed weekly before each startup, or a visual inspection around the machine should be conducted daily. Preventive maintenance should be carried out promptly.

Every two weeks, perform operational checks on the machines (for those backup units that have never been powered on) by starting them up and running them for 5 minutes.

2. Conduct monthly inspections (powering on backup machines that have never been in operation) and operate the machines under a load of at least 50% for 1-2 hours.

Every 6 months or 250 hours of operation, inspect daily, and never allow the diesel engine to run for extended periods at low load.
