Operation Operation Operation Operation Checklist Checklist Checklist Before Before Before Starting Starting Starting • Check the compressed air supply according to its operator manual. Make sure the air being supplied is clean and relatively free of moisture and oil to prevent water contamination of the air control components.
Operation Connecting Connecting Connecting the the the Blast Blast Blast Hose Hose Hose and and and Air Air Air Hose Hose Hose 1. Always purge the air supply hose 15–20 seconds before connecting the air supply hose from the compressor (or on-site compressed air source) to the panel.
Operation Setting Setting Setting Up Up Up the the the Equipment Equipment Equipment 1. Disconnect the abrasive hose at the cam and groove with the abrasive ball valve closed.
Operation 8. Turn the selector valve to RINSE. 9. Disengage the Emergency Stop. NOTE: NOTE: NOTE: The water pump will not work unless the Emergency Stop is disengaged. 10. Align the bung handle with the pin slot, and then rmly push and turn the handle 90° after the pin is below the bracket slot.
Operation 13. When the water level reaches the bung seal, rotate the handle to release the bung pin (this will cause the bung to pop up against the seal and close the bung). 14. Turn the selector valve to FILL. NOTE: NOTE: NOTE: The water pump should begin cycling.
Operation 20. Open the abrasive ball valve. NOTE: NOTE: NOTE: Make sure the pot pressure returns to the initial setting (it will not return to the initial setting if the metering valve is closed). 21. Engage the blast control switch and begin blasting.
Operation Blasting Blasting Blasting Tips Tips Tips When rst learning the effects of the blaster, get a better understanding of the results by starting at a shallow angle (closer to 0° than to 90°) and keep the nozzle approximately 16 in. (40 cm) from the application.
Operation Metering Metering Metering Valve Valve Valve Settings Settings Settings There is no xed formula for what works best in each application. The information below works best for the majority of the time. From this initial setting, adjustments can be made up or down to get the fastest removal rates without damage to the surface.
Operation Using Using Using the the the Wash Wash Wash Feature Feature Feature The wash feature causes air-driven water (without abrasive) to blast and rinse areas that have already been blasted with abrasive. It is also a convenient feature for ushing abrasive from the blast hose.
Operation Relling Relling Relling the the the Pot Pot Pot with with with Abrasive Abrasive Abrasive 1. Close the abrasive ball valve. 2. Turn the selector valve to RINSE. 3. Open the dump valve slowly to relieve the water pressure in the pot.
Operation Shutting Shutting Shutting Down Down Down 1. When you have nished blasting, perform wash until all of the abrasive is ushed from the blast hose. See Using the Wash Feature, page 17 . 2. Turn the selector valve to RINSE, and with the abrasive ball valve closed, continue to blast until water is cleared from the hose.
Operation 8. Engage the bung pin to hold the bung open and allow air to enter. 9. Open the abrasive ball valve and ush the pot of any remaining abrasive material. 10. Close the pot bung and connect the abrasive hose. Relieve pressure to complete system shutdown (see Pressure Relief Procedure, page 8 ).
Operation Winterizing Winterizing Winterizing the the the Equipment Equipment Equipment Vapor-Abrasive Blasters must be winterized whenever there is a possibility of freezing temperatures during storage.
Troubleshooting Troubleshooting Troubleshooting Troubleshooting Problem Problem Problem Cause Cause Cause Solution Solution Solution The air supply is inadequate. Make sure the air inlet pressure gauge reads 100-125 psi. If the gauge does not read 100–125 psi, check the air compressor for proper setup.
Troubleshooting Problem Problem Problem Cause Cause Cause Solution Solution Solution The pot does not have a sufcient amount of abrasive. See Relling the Pot with Abrasive, page 18 . The system is not properly set up. See Setting Up the Equipment, page 11 .
Troubleshooting Problem Problem Problem Cause Cause Cause Solution Solution Solution The pneumatic blast control circuit is malfunctioning. See Pneumatic Blast Control Circuit, page 27 . The main air regulator is stuck open. See Repairing the Main Air Regulator, page 28 (EQ600 – Kit 17C131, EQ300 – Kit 17C129).
Troubleshooting Problem Problem Problem Cause Cause Cause Solution Solution Solution The unit is not on a level surface. Place the unit on a level surface. If this is impossible, the Auto-Vent must be on the higher side of the unit. The initial pot pressure is not set correctly.
Troubleshooting Troubleshooting Troubleshooting Troubleshooting Examples Examples Examples Checking Checking Checking for for for Leaks Leaks Leaks 1. Open the dump valve. Check pot pressure gauge, then close the dump valve. Look at the pressure gauge to conrm that all pressure has been relieved from the pot.
Troubleshooting Pneumatic Pneumatic Pneumatic Blast Blast Blast Control Control Control Circuit Circuit Circuit 1. At the Air-Relay, disconnect the push-to-connect tubing and check the trigger circuit (from the blast control handle). 2. With the blast control activated, conrm that there is air owing from the disconnected tube.

Repair Flushing Flushing Flushing the the the Diaphragm Diaphragm Diaphragm Valve Valve Valve This procedure can be performed with the component still mounted in the panel. If large-grit abrasive or other foreign matter become lodged in the diaphragm valve, it will become necessary to ush the valve.
Repair Repairing Repairing Repairing the the the Diaphragm Diaphragm Diaphragm Valve Valve Valve NOTE: NOTE: NOTE: The diaphragm (17C127 – EQ300, 17C128 – EQ600) can be replaced without removing the assembly from the panel. You will need an 8 mm Allen wrench for the EQ600S and a 6 mm for the EQ300S.
Repair Cleaning Cleaning Cleaning the the the Auto Auto Auto - - - Vent Vent Vent Valve Valve Valve After the pop-up has been closed while lling the pot, the auto-vent valve should release air (you should be able to hear the air venting). The pot pressure gauge will not show pressure until the auto-vent valve has bled all of the air and sealed.
