BLASTING WEAR PARTS
Certain parts wear faster than others and will require regular maintenance and inspection depending on the method of
blasting you are using as well as the abrasive you are blasting with. These items should be inspected for damage or wear,
and replaced an average of 400 hours if dry-blasting, or 2000 hours if wet-blasting.
Wear items include but are not limited to:
FLUSHING BLAST POT OUT
Regularly flushing the pot avoids buildup on inside walls, which could inhibit the system. Once a month or so, you should
rinse the pot out:
1. Fully depressurize machine.
2. Remove 2 bolts and 2 air inlet body lugs from bottom of machine.
3. Remove air inlet jet and gasket.
4. Push casting and air hose out of the way.
5. Flush out inside of equipment with water.
6. Once finished, replace the gasket, inlet jet, and lugs and bolts.

TO REMOVE BRASS COUPLINGS FROM OLD HOSE:
1. Lock hose in vice and remove screw using a phillips head screwdriver or drill.
2. Unscrew the brass coupling from hose turning counter-clockwise. You may need a bar or rod to do this.
TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE:
1. Wrap the end of the hose in several layers of friction tape, slightly beyond the point the brass will cover.
2. Place coupling over friction tape and hose, screwing clockwise until hose end pushes against inside brass ridge of
coupling. You may need a bar or rod to get it tight.
3. Wrap screws with Teflon tape and screw into designated holes until tight.
PINCH HOSE MAINTENANCE GUIDE
Rotate the pinch hose every 10-15 hours of blasting. Perform a visual and physical inspection to insure integrity. Look and
feel for signs of wear, softness, or bulges. Completely replace pinch hose before it fails at about 40 hours of use, or after
being rotated 4 times.
