Pressure Relief Procedure Pressure Relief Relief Procedure Procedure Pressure Pressure Relief Procedure 2. Close the abrasive ball valve. 3. Turn the compressor off and close the inlet ball valve. Close the compressor supply air Follow the Pressure Relief Procedure valve. Engage the blast control switch to relieve whenever you see this symbol.
Operation Operation Operation Operation Checklist Before Before Starting Starting Checklist Checklist Before Starting • Make sure the water tank will remain fully supplied with clean water to avoid any possibility of the pump running dry during blasting. • Check the compressed air supply according to its operator manual.
Operation Connecting the the Blast Blast Hose Hose and and Air Connecting Connecting Blast Hose 3. Open the air supply valve (125 psi, 8.6 Bar, 0.86 Hose MPa maximum). If necessary, use a regulator in Hose Hose the supply air line to meet these specifications. 1.
Operation Setting Up Up the the Equipment Equipment Setting Setting Equipment 3. Reconnect the abrasive hose. 4. Disconnect the pump inlet hose and flush the water tank to remove any remaining debris. Reconnect the pump inlet hose. 5. Fill the water tank only with fresh water, then open the inlet ball valve.

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 the the Wash Wash Feature Feature Using Using Wash Feature 2. Turn the selector valve to WASH. 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 flushing abrasive from the blast hose.
Operation Refilling the the Pot Pot with with Abrasive Abrasive Refilling Refilling with Abrasive 4. After all of the pressure in the pot has been relieved, engage the bung pin by compressing the spring and turning the handle 90° to hold the bung in the open position.
Operation Shutting Down Down Shutting Shutting Down 5. Hold a bucket under the cam-lock coupler, then turn the selector valve to WASH. This will clean debris from the cam-lock coupler and gasket. NOTE: NOTE: NOTE: Make sure the gasket is in place after the procedure.

With the blast control activated, confirm that there is air flowing from the disconnected tube. 1. At the Air-Relay, disconnect the push-to-connect NOTE: NOTE: NOTE: The air flow should be at supply air tubing and check the trigger circuit (from the blast pressure but the air volume is reduced due to control handle).

Unscrew the diaphragm cover for access to the diaphragm and to the end of the piston shaft. NOTE: NOTE: NOTE: Repair parts are available in Kit 17C131 (EQ600) or Kit 17C129 (EQ300).
Repair Flushing the the Diaphragm Diaphragm Valve Valve Flushing Flushing Diaphragm Valve 3. Disconnect the quick coupling at the abrasive ball valve (not at the bottom of the pot). 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 flush the valve.
Repair Repairing the the Diaphragm Diaphragm Valve Valve Repairing Repairing Diaphragm Valve 3. Replace the diaphragm (natural rubber compound) and hand-tighten it as far as possible to establish the alignment with the canister. NOTE: NOTE: NOTE: There are two shims between the diaphragm and the actuator.
Repair Cleaning the the Auto Auto - - - Vent Vent Valve Valve Cleaning Cleaning Auto Vent Valve 3. Use the rinse hose to force water backwards into the valve stem. After the pop-up has been closed while filling the pot, the auto-vent valve should release air (you should be able to hear the air venting).
