OTHER MAINTENANCE ITEMS:
1. You should make every effort to protect your air compressor from any
damage it may receive from your abrasive blasting work. Your best option
is to keep the compressor up wind from the abrasive blasting, and the
greater the distance between them, the better. Other than that, you should
continue standard maintenance procedures for the compressor.
2. Some parts of the abrasive blaster will wear much more rapidly than
others, the parts needing close attention carry the air/abrasive mixture,
starting with the abrasive hose (25) and going through the metal fillings,
the DEADMAN valve (34) and the ceramic nozzles (28).
3. If air leaks develop in any of these parts, you should stop all work ,and find
what needs to be repaired or replaced. When it’s new, the abrasive hose
(25) has 2 cord piles and the walls are 1/4” thick. As the interior diameter is
abraded, this wall becomes thinner and thinner. One way to inspect the
hose and other parts affected by the blasting is to put on your protective
clothing. Then pressurize the system and close the nozzle shut off the
valve (19). Listen for air leaks, fix any leaks before operating. You can
also spot places in the hose where the wall is getting very thin. 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.
