How do I pop out the insert without damaging the cartridge, fitting, etc.? I've read elsewhere that this can be disassembled, but I have arthritic hands that have no dexterity and shake a lot, so it's all too easy for me to break things. Because of this, and being on an extremely low budget (disability), the last thing I want to do is break the few pieces I currently have.![]()
I'm assuming this is a 510 cart.
Round carts- use a fingernail to catch the edge of the insert with the hole in it. You can also use a small paperclip in the hole and wiggle it. It comes out easily once you apply pressure. There's another insert down in the cart with a hole in it, too. Remove the inner insert and save it. I toss the inner inserts in a ziplock with other parts in case I ever need them for some reason.
Whistle tips- you can squeeze with fingers and rotate back and forth to loosen it or use a paper clip inserted into the hole as above. Remove the inner insert and store.
Liquid accumulates in the cart until you take a puff and it works through the baffles to your lips (yuck). It builds up a tiny drop at a time until it gets to the end of the mouthpiece. Once this happens you get juice on the lips frequently. Periodic cleaning will minimize the problem. I clean mine routinely, once a week or so, sometimes more often. Once you've done it once you will realize how easy it is.
