Thread: Haskel Mini Sport Booster adjustment

    Haskel Mini Sport Booster adjustment

    I used my Haskel MSB-9000 for the first time last night to boost my LP27 from 1700psi (117 bar) to 3000psi (207 bar). The booster was cycling about once every 4 - 5 seconds. I was filling from AL40 that had 2000 psi (138 bar). I read in the instruction that you can adjust the muffler to bring the cycle up to 50 - 60 a min, which is the speed recommended by the manufacture. My question is how do you adjust the muffler? I'm not a fan of just messing with things blindly, and the owners manual doesn't specifically instruct how to adjust it. Any help will be appreciated.

    OK, now that I have realized that I'm only partially mental. I see that the exhaust if very easy to adjust when you have a working (adjustable) muffler. The one that came with my Haskel was 100% open and stuck that way. I had to use a pair of vice grip pliers to get it to adjust because it was so frozen, and using a screwdriver just broke the brass slot apart. The company sent me a new muffler and all is good.
