GENERAL OPERATION After completing start-up steps 1-12, the MistBlaster blasting system is ready for operation. When the 3-way blast mode selector valve (front of control panel), is set to the dry blasting position. Depressing the corresponding dead-man control will actuate the auto air valve and abrasive metering valve simultaneously, allowing air to pass down through the choke valve, through the ‘pusher’...
The pot is still under pressure. IMPORTANT: When switching from dry or mist blast to wash down, there will still be abrasive in the blast line for a brief period. Always adhere to all safety protocol when operating the MistBlaster™. PROPER SHUT DOWN PROCEDURE It is recommended that when blasting has finished, the blast hose should be flushed free of all abrasive and water.
When operating in dry blast mode, ensure that the transfer pump is off. In addition, ensure that the transfer pump is off when the Mist Blaster™ is not in use. Consult a BlastOne sales representative about suitable water supply options.
