I dont know anything about the HF sand blaster, but had an experience with one from TSC that gave me fits untill I read the instructions carefully.
My TSC sand blaster is a vacuum type, which sucks sand from the bottom of the sand tank, through a hose to the blaster gun.
When I first tried the thing I pushed the sand suction hose fully on the nipple on the bottom of the sand tank. The thing was pathetic, would hardly suck any sand and plugged the hose / nozzle constantly. I set the thing aside, deciding it was a sad piece of unusable junk.
About 2 years later i needed to do some sand blasting, so drug the blaster back out to see if I could make the pathetic thing work well enough to get the job done.
I read the instruction sheet and found an adjustment that I had originally missed. It seems my blaaster was designed to spray either liquid cleaner or dry sand. The part I missed was that the hose nipple in the bottom of the tank has about a 1/4 inch air bleed hole in it's side, about 1/3 from the tank end of the nipple. To spray a liquid, you push the suction hose fully on the nipple so the air bleed hole is blocked. When using dry sand, you only push the suction hose on part way, so the air bleed hole is exposed to the air. This puts the sand on a stream of air to carry it to the blast nozzle. I checked and yep, I had the hose pushed fully on, blocking the air bleed hole. I pulled the hose off the nipple far enough to expose that air bleed hole. and gave it another try. My formerly useless piece of junk was now a metal eating tiger, I think I could cut 1/8 plate with it. :-) I tried all of the several different bags of blasting sand I bought when trying to get the thing to work. It now ate all of them like a hungry bear.
Might some simple little adjustment like that be the problem with your HF sand blaster ???
