taking breaks to let the pump cool down to avoid damage to seals etc.
those seals need replaced about roughly ever 3-6 months. also make sure to check any filters on the pump that traps moisture/particulates. The pumps are a great idea but the time it takes, plus the fatigue, makes it not very efficient to fill our 4500psi bottles. It does work to get them up to 3000psi though, just takes some time and strength
