As long as a toothbrush is used for a period of time, the bristles will be covered with dirt, which is difficult to clean thoroughly. The air compressor head is like a toothbrush that has been used for a long time. There will be oil stains, carbon deposits, sediments, and rust inside. In addition, air compressors that have used different brands of engine oil will also have black glue similar to asphalt. Therefore, it is necessary to use cleaning agents regularly to clean the machine head, paint bucket, radiator, and oil pipes to eliminate safety hazards.
① First run the air compressor for a few minutes to allow the oil to reach room temperature;
②. Turn off the air compressor, wait for the internal pressure to be released, open the refueling cap, pour in the cleaning agent, and then tighten the refueling cap;
③. Turn on the air compressor and run for 30 minutes;
④. Drain the old engine oil and then add new engine oil.
The temperature of the air compressor after cleaning will drop by at least 10 degrees.
