Scott,
I'm not sure what style of cabinet or nozzle you have. I suspect gravity
feed from below with a trigger gun? If so, hold the trigger open, and block
the nozzle outlet. his will blow the compressed air back into the hopper,
cleaning the hose and hopper intake of any "grunge". As you reuse the sand
or glass more and more, you'll find you get more plugs. Not much you can
do, except blow back (as above) more frequently or change media more
frequently.... no biggie. Be sure also that your media is dry. In the moist
summertime, condensation in the air lines is common as is just the ambient
humidity. Be sure to have a water trap in line. (you can make one with just
a T in line and a hose dropping down into a bucket with a valve at the end
of the hose. Open this valve occasionally to let the water out.) I've found
it helpful to leave the light on in the cabinet with the vacuum running to
help keep the hopper media dry.
Good luck. Have a blast.
