INSTALLING AIR QUICK COUPLER
Prepare a standard 1/4 in. NPT male air quick coupler (sold separately) for use with your tool.
1. Wrap the external threads of the male quick coupler with sealant tape.
a. Wrap the tape in a clockwise direction so it will not unravel.
b. Do not tape all the threads. Leave several leading threads unwrapped for
easier alignment.
2. Screw the quick coupler into the tool’s air inlet and tighten with a wrench until snug.
3. Run compressor at a low volume and check the connection for air leaks. Do not use the tool
until all air leaks are repaired or the faulty component is replaced.
OPERATION
1. Connect the air source to the air quick coupler on the abrasive blasting gun (13).
2. Pour the selected abrasive media through the screen (1) into the plastic hopper bucket (2).
3. Firmly grasp the abrasive blasting gun (13) and depress the trigger. This should begin the
abrasive flow. If no flow is seen, you may need to clear the siphon funnel. Simply shake the
bucket slightly to dislodge any blockage. If this does not work, try dislodging the media with
a drill bit held in your hand. You need to discard any moist media.
4. Now you may begin finishing your part. You should move the blast stream continuously over
the part in an even and circular motion. To avoid undesirable peening, the flow should not be

the media over a larger area, reducing the tool’s efficiency. The compressor will also need to
