    The warranty period begins when the equipment ships from the Comco facility and applies to the original owner only. Comco is not liable for damages from any cause or use of such equipment beyond the cost of repairing any defective parts.

  • Page 6: Safety Precautions

    Working with a Device that is Pressurized The MicroBlaster uses pressurized air to perform its basic function. To minimize the risk of an accident related to air pressure, Comco recommends the following: √ The air supply system should have a shutoff valve located upstream of the blasting machine so that the supply pressure can be turned off independently of the blaster.
  • Page 7 The MicroBlaster uses several types of abrasive media that should not be inhaled or ingested in large quantities or maintained in prolonged contact with the skin. When working with the abrasive media, Comco recommends the following: √ Do not direct the abrasive blast on bare skin or face/eyes.
  • Page 8 Also, always fill the tank through the flapper valve to greatly reduce the amount of wear on the threads. Material safety data sheets (MSDS’s) for all abrasives distributed by Comco are available from the Comco factory. Every powder shipment includes an MSDS.

  • Page 36 Section 3: Using the MicroBlaster MicroBlaster MB1000 Nozzle Distance The velocity at which the abrasive particles are expelled from the nozzle produces a well-defined stream that only flares about 7 - 10 degrees. Therefore, the distance the nozzle is held from the work surface will determine the size of the blast pattern as well as the material removal rate (or cutting action).
  • Page 37 A significant increase in abrasive flow does not always increase the speed at which parts can be processed. The micro-abrasive blasting process is optimized to work with less abrasive, using air flow and particle velocity to improve efficiency.
