Installation steps:
1. First, you must ensure that your air tank is zero, and then exhaust all the air (if there is still air, it will be more troublesome to extract the old air).
2. Take out the brake cleaner and clean the surrounding environment.
3. Use snap ring pliers to remove the snap ring, and then pull out the exhaust valve.
4. Apply the silicone grease we provided to your fingers, put it on the top of the drain valve, and then apply it on the drain valve.
5. Rotate and push up.
6. Put in the snap ring.
7. Test.
