The easiest way to look at the small aluminum plate at the lower right of the cab of Komatsu excavator is to look at whether the words on it are Japanese or Chinese. Of course, this small aluminum plate is sometimes fake.

Look at every screw on Komatsu excavator. The pressure on imported and domestic screws is different.

Looking at the color of the whole machine, the imported paint is very sun-resistant, and the paint sprayed by the original imported machine is sprayed directly on the machine without putty.

The display screen of the imported machine is all Japanese, and Chinese can't be adjusted.

Open the lid of the battery toolbox, which has instructions for butter and a box with an air filter. If it is Chinese, it is made in China, and Japanese is made in Japan.

Look at the glass. The original imported Komatsu excavator has a lightning icon in the lower left corner of the glass front, with several strings of English beside it. All the old and new machines are imported with this brand of glass, including cars imported from Japan.

Check the machine number on the nameplate. If there are English letters in front of the machine number, it is a domestic Komatsu excavator. If there is no letter before the machine number, the machine number is imported.

The three gear oil-filled screws on the driving wheel of imported Komatsu excavator are nuts, and the screws of domestic Komatsu excavator are hexagonal.
