Preparation before Maintenance of Air Compressors

What preparations should I do before the air compressor maintenance?

To ensure that the unit is operating and has a long service life, good maintenance is the key. Therefore, the maintenance procedure for the air compressor must be seriously performed. Before you keep maintenance, at least the following preparation:

1.1. Cut off the host power and hang on the power switch.
1.2. Closing the shut-off valve to the air supply system to prevent the air to flow back to the maintained part. Never rely on the one-way valve to isolate the gas supply system.
1.3. Open the manual amplifier valve, empty the pressure in the system, keep the empty valve in the open state.
1.4. For water-cooled machines, the water supply system must be closed to release the water pipe pressure.
1.5. Make sure the compressor has been cooled to prevent burns from burns.
1.6. Wipe the ground oil marks, the water to prevent slipping.
