1. or cause damage to the tool If the tool does not rotate when the dump valve is closed the operator should try closing the dump valve slowly a few times to build up pressure slowly until normal operation is achieved This also flushes debris out of the tool The drilled nozzle head will last between 20 and 60 hours Worn jets decrease the cutting rate The tool may begin to hydraulic when cleaning plugged tubes This occurs if the the jets are not effectively cutting the material into smaller pieces When using the Shrouded Banshee in plugged tubes it can be pushed against the deposit However it will advance as soon as the jets clean an opening the size of the tool itself If it is desired to completely clean the tube to the wall the feed rate of the tool must be slowed to ensure adequate cleaning Maintenance If the Banshee stops rotating check the nozzle orifices in the head for plugging if one becomes plugged the swivel will likely not rotate If this does not solve the problem the swivel should be disassembled and inspected recommends WD 40 to prevent corrosion pitting which will cause the parts to crack Warning Use correctly sized open end wrench to fit flats provided on the Inlet Nut when attaching tool to lance Do not use Pipe Wrench or pliers with teeth as this can crush and crack the hardened steel body leading to tool breakage in operation BN13 002 XX Inlet Nut BN13 001 Shaft There are four small holes ex2. Shrouded Banshee Tube Spinner BNS13 SAPATENTS COM The Shrouded Banshees are self rotating swivels designed for tube cleaning on the end of a rigid lance The shroud allows the tool to be pushed against the material being removed without stopping rotation of the head Because of the shroud surrounding the head no rearward facing pulling jets can be used in the head all the jets point forward resulting in a pushing thrust force that must be resisted by the rigid lance and machine WARNING the Shrouded Banshee is not designed to be used on a manually hand fed flex lance The only alternative to use the Shrouded Banshee manually on a flex lance is to use a pulling nozzle between the hose end and the inlet to the Banshee to balance against the thrust force However the Shrouded Banshees can be used with flex lances that are used with powered equipment not in the hands of waterblast users Nozzle Heads The standard head design BNS 043 A has five forward facing jets at 20 30 and 40 and 60 degrees Each head is capable of a range of pressure and flow as shown in the chart The pushing thrust force of the jets ranges from 15 to 40 pounds depending on operating pressure The nozzle heads are wear items that will need to be replaced after 20 to 60 hours depending on water filtration and operating pressure The wrench flats on the BN13 shaft are 13 64 in or 5 mm and the inlet nut and body have 7 16 in flats these wrenches are available from S
