which part of it is the plunger?

>>>That's the part you push down on.



Does anyone know what that clear plastic ring could have been that fell out of the glass barrel?

>>>Sounds like a washer. You could probably find one at any hardware store that sells them.



Also sometimes when i press down it wont go down all the way because of the air pressure so it wont go down.

>>>That's because the bit (little round plate with four holes) on the inside is clogged. You then need to dismantle the pump clean it and start over. Clogs happen frequently unless you are using the tiniest pinks. That's why I run the pinks through once first. It still happens but less often.



Can someone give me directions on how to use it? It didnt include any when i got it.

>>>Use it like a baseball bat or some chopsticks. Sometimes I just swing it around all crazy fancy like a James Bond tool. Just kidding. Put the pinks (or mix) in and set the stopper (ring thing on the plunger) to how much you want to dose. Insert and push.
