1. ATD 8402 90LB PRESSURE BLASTER INSTRUCTION MANUAL SAVE THESE INSTRUCTIONS SAFETY INSTRUCTIONS FOR SANDBLASTER 1 5 6 Before opening the tank release the air pressure on the sand tank To do this turn off the air supply valve 14 to release pressure in the line Be sure that the tank pressure gauge 05 reads zero then open the tank Maintain correct air pressure Pressure should not exceed 125PSI If it does the safety valve 06 is supposed to release the excess pressure If it doesn t release excess pressure stop all work immediately and use the air compressor to reduce the excess pressure Do not investigate the sandblaster s pressure problem until the pressure gauge 05 reads zero When using pneumatic equipment basic safety precautions should always be followed to reduce the risk of personal injury and hazards due to over pressurization Do not operate the unit when tired or under the influence of alcohol or drugs When servicing only use parts and accessories intended for use with this unit Do not allow sand blaster to be pressurized while unattended or not in use WARNING The warnings and cautions discussed in this instruction manual cannot cover all possible conditions and situations that may occur It must be understood by the operator that common sense and caution are factors that cannot be built into this product but must be supplied by the operator ASSEMBLY USE PTFE tape for all threade2.

9. 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 affe
