หัวพ่นทรายขนาดเล็ก MINI SANDBLASTER

Operation:
For general erasing, clean dry air at pressures of 30 to 45 PSI may be used. To be sure of satisfactory performance a Moisture Trap or Regulator with Moisture Trap should be used to remove, within their rated capacity, water oil and other impurities from your source of air supply. Air compressors with a air supply tank are recommended. Expect a slight trickle of abrasive to flow out after the button has released. This is caused by air pressure in the cup being relieved.
1. Attach air hose coupling to Valve Casing
2. Unscrew Cover
3. Fill cup 3/4 full with clean dry sand, tighten cover securely.
4. To prevent leaks, do not get any abrasive on the cup threads
5. Regulate air pressure for erasing on paper surfaces to approximately 30 PSI. Use a
1. higher air pressure of 45 to 65 PSI for metal, gold castings, plastic or glass work.
6. Hold the Model G78 the way you would a pencil. Move the Model G78 with the Tip
1. about 1/8” to 1/2” above the work surface. Adjust to achieve results desired.
7. Adjust Control Screw to the lowest point to avoid excessive use of abrasive.
8. For work requiring fast, heavy abrasive cutting, use Fast Cutting Abrasive and high
1. air pressure. Hold tip of the Model G78 very close to the working surface to cut
1. faster. Hold at a distance for blending and broad coverage.
WARNING: Maximum Air Pressure 65 PSI แก้ไขข้อมูลเมื่อ 16 Oct 17 01:52
