Good media carried to dust collector. | New bags. | Continue use until bag “cake” forms (approximately eight hours of operation) . |\n|  | Systems with reclaimers:\u003Cbr>tuning band is open too far. | Adjust tuning band. |\n|  | Insufficient media in suction hopper allows secondary air to enter. | Add media to recommended media level. |\n|  | Systems without reclaimers: slide gate is open too far. | Adjust slide gate. |\n|  | Media too fine. | Use more coarse media. |\n|  | Pressure systems: Worn plunger or sealing ring leaking air into reclaimer. | Replace plunger and/or sealing ring. |\n| 2. Media escaping to the work area from dust collector. | Hole in dust bag(s)or loose bag(s) . | Replace leaking bag(s)or refasten bag(s) . |\n| 3. Poor visibility during blasting. | Reclaimer not adjusted properly. | Adjust reclaimer air inlet settings See 3.6 Equipment Adjustments |\n|  | Clogged dust bag(s) . | Shake dust bag or dust collector bags. |\n|  | “Blinded” filters (reduced air flow due to age of bag) . | Over a period of years dust may penetrate the dust bag to the extent that normal air flow is restricted even when bags are shaken regularly. When this condition is reached, replace the filters. |\n|  | Fan rotation backwards. | Reverse the fan rotation. |\n|  | Media has high dust content. | Replace media and adjust reclaimer tuning band. |\n|  | Recovery hose blocked. | Remove hose, inspect and remove obstruction. |\n|  | Cabinet air inlet plugged. | Blow filter clean with air line. |\n|  | Dust collector door leaks air. | Tighten door, replace gasket if necessary. |\n|  | Blast nozzle or air jet too large. | Replace worn nozzle with recommended size: maximum ¼”diameter pressure, maximum 7/32”air jet for suction. |\n\n\n| Trouble | Probable Cause | Remedy |\n| --- | --- | --- |\n| 3. Poor visibility during blasting (continued) . | Operating air pressure too high. | Decrease pressure to within recommended range. |\n| 4. No air or media flow from nozzle. | Compressed air line shut off. | Open all air valves from compressor. |\n|  | Cabinet Doors not tightly closed. | Close cabinet doors sealing door interlock. |\n|  | Regulator adjusted to zero. | Adjust regulator. |\n|  | Nozzle clogged. | Disassemble and clean nozzle. |\n|  | Door interlock air hose leaking. | Replace hose (if problem continues see 5.2 Troubleshooting Pneumatic Control Circuit) . |\n| 5. Poor production rate. | Low blast air pressure. | Increase pressure within the specified range. |\n|  | Nozzle too small (the smaller the nozzle, the\u003Cbr>smaller the blast pattern) . | Install a larger nozzle (and air jet on suction systems) to accommodate your production needs. |\n|  | Improper media. | See 3.1 Media Selection and Use. |\n|  | Improper media flow. | See 3.6 Equipment Adjustments. |\n|  | Low media level. | Add media to maintain recommended level. |\n|  | Parts to be blasted are oily or wet. | Parts to be processed must be absolutely dry and free of oil, grease, etc. |\n|  | Media has high dust content (Blast media breaks down and must be replaced on a regular basis) . | Remove old media from system and replace with new. Adjust reclaimer tuning band. See 3.6 Equipment Adjustments. |\n| 6. Static charge build-up and discharge annoys the operator. | Low quality blast hose (poor conductor of static charge) . | Replace blast hose with one of high quality. Static charges are created and build up by the air and media moving at high velocity through the blast hose. |\n|  | System grounded improperly. | Earth ground the system. |\n|  | Part insulated, resting on rubber mat. | Place part on metal surface, i.e. cabinet floor or turntable top. |\n|  | Low compressed air and ambient humidity. | Install Empire Anti Static Strap, part 510411. |\n| 7. Blast air flow, but intermittent or no media flow. | Blast air pressure too low. | Adjust and maintain pressure within recommended range","cbCaiec8rR7xx10K","https://ap.wps.com/l/cbCaiec8rR7xx10K","pdf",262472,"English","# 5.0 Troubleshooting\n## 5.1 Troubleshooting Chart\n## 5.2 Troubleshooting the Pneumatic Control Circuit","[{\"question\":\"What causes poor visibility during blasting, and how should it be remedied?\",\"answer\":\"Poor visibility can result from improper reclaimer adjustment, clogged dust bag(s), blinded filters, or high dust content in the media.
