When we use a stamped pump head, sometimes the pump head may get stuck or encounter other problems, which can prevent it from stamping smoothly. At this point, it is necessary to press the pump head back in order to continue using it.
Firstly, we need to determine if the pump head is really stuck. Sometimes, we may misunderstand that it is stuck, but in reality, it only requires a little bit of force. Therefore, we need to observe carefully and press down as hard as possible.
If it really gets stuck, then we can try pushing it back. At this point, some force is required, but we should not use too much force as it may cause damage or rupture of the pump head. We can also try using tools such as pliers or wrenches to gently push the pump head.
If none of the above methods are successful, then we need to disassemble the pump head, readjust or replace the parts. This requires some skills and experience, and if you are unsure how to operate, it is best to seek professional help to handle it.
In short, when encountering the problem of the pump head getting stuck during pressing, we should calmly face it and try different methods to re press.
