Answer: Before starting the air compressor, you must first check the pre-startup inspection items and check if there are any abnormalities before starting:
(1) Press the "Start" button. After starting, the "Start" indicator light should be on and the unit starts to run.
(2) After about 2 seconds, the unit automatically loads, the intake valve opens, and the pointers of the lubricating oil pressure gauge and the exhaust pressure gauge rise.
(3) After starting and loading, check whether the oil level is within the normal range.
(4) Check whether there is any air leakage, oil leakage or water leakage at each connection part. The number of starts should not exceed 3 times within 1 hour.
(5) Put the air compressor into joint control.
