Every time the air compressor runs around 2000h, in order to remove dust from the heat dissipation surface, the cooler on the fan bracket is removed to sweep the hole cover open, and the cooler is swept with a dust air gun until the dust on the heat dissipation surface is swept clean. Tiering heat dissipation surface dirt is serious, difficult to sweep clean, can unload the cooler, pour out the oil in the cooler and seal four import and export to prevent dirt from entering, and then use compressed air to blow off the two sides of the dust or rinse with water, and finally blow dry the surface of the water stains.
Put it back in place. Remember! Do not use iron brushes and other hard objects to scrape and remove dirt, so as not to damage the radiator surface.
