MAINTENANCE
1. You should make every effort to protect your air compressor from any damage it may
receive from your sandblaster working. The best option is to keep the compressor in a
separate room from the sandblaster, and using a long hose to provide the PSI needed to
do work. A second choice is to keep the compressor up wind from the sandblasting and
the greater the distance between them the better.
2.
Some parts of the sandblaster will wear much more rapidly than others. The parts
needing close attention carry the air/abrasive mixture, starting with the sand hose (#25)
and going through the metal fittings, and finally the sandblasting gun.
3.
If air leaks develop in any of these parts, stop all work to find out what needs to be
repaired or replaced. When it’s new, the sand hose (#25) has 2 cord pile and the walls
are 1/4” thick. As sand is blasted through the hose, this wall will become thinner and
thinner. One way to inspect the hose and other parts affected by the blasting is to put on
the protective clothing. Then pressurize the system and close the nozzle of the
sandblasting gun. Close your hand loosely around the hose and run it up and down. You
will be able feel any leaks. You can also spot places where the wall is getting very thin,
as these show up as blisters in the hose. If you find such a blister, get a new hose
immediately. If that blister breaks, the abrasive will come out of the side of the hose at
60 PSI or more.
AIR SUPPLY REQUIREMENT
Sandblasting requires a large volume of air at high pressure. The efficiency of your
sandblaster can be adversely affected by the use of too small of an air supply hose,
insufficient air pressure or an oversized nozzle.
