How can we determine whether the diesel generator set we've purchased is new or not? Dazai Power advises you that you can differentiate through a method of "ask, observe, and test the machine."

Inquiry includes the production date, name, and type of diesel generator sets, among other questions.

Inspect for any repaint from top to bottom on the body, ensure the body label matches the type specified in the operating instructions, check for any unburned particles inside the equipment, and look for signs of fuel combustion.

Three trial runs are conducted to carefully inspect the diesel generator set, involving operations such as cranking the crankshaft, turning the flywheel, and starting the machine. This trial run is a crucial step.
