Don’t use any petroleum-oil based products in the tank or it will vaporize and detonate (dieseling)
If you need to lube use only silicon based divers products that are compatible with HPA.
There is not kidding here. You are going to damage the tank and get hurt
if you have a cent or a dime and the pump fill adapter, put the coin flat in the adapter then put the adapter on the tank. The coin should be flat on the tophat inside the adapter.
slowly tighten the adapter until you hear air coming out. Slow is better. Leave it there for a while.
When it is empty, remove the adapter. If you can depress the tophat manually you are good to go.
