The minimum pipe diameter of the oil return pipe must be ensured, and the oil pipe is not twisted, bent, and the oil is smooth. Check the oil seal and the size of the cabinet. Replace it if it does not meet the standard. 2. Move the spindle to check whether the neck clearance is too large.

Check the oil leakage of the air compressor and re-adjust the tightness of the belt. It is advisable to press the thumb 10 mm. 5.
