Hi, my Coleman air compressor's regulator knob shot off the manifold during use one day. I replaced the knob and the smaller internal parts of the knob. The new knob shot off again after a few minutes of holding air. Would really appreciate any help into fixing this issue. This is the only issue in years I've had with this compressor and would like to keep it going for more years to come. 

I have the exact same problem with my BL0502710, I see that nobody has replied to help. I called and got no answer so I guess we are just supposed to buy new ones, that are now three times the price I paid for mine. Happy days!!!!
