I have a couple more questions, perhaps being thick but...
On mine, the cylinder is internal to the inflation bladder part, so how do you get at it?? Been peering at it for a while and wondering if I am missing something obvious! Photo attached.
The only bit on the outside is the Hammar unit and the pull toggle, the cylinder seems (can't see it obviously, but going on feel) seems to screw into the inside of the Hammar unit. Does the Hammar unit come off the inflation bladder somehow, and if so how, would it be a twist off thing or what? Don't want to force anything in case it breaks...
Though the main question is about my own jackets we also have similar Marinepool jackets used for commercial purposes at work, as far as I know these get sent away to be serviced so if it is simple to do I wondered if these could be done here too as it would make life much easier.
What's the "Baltic" website?
