Fit it into the air hose connecting to the air compressor, fasten with a hose clamp. Push the coupler again and fit in the opposite side of the cone shaped end, release and the connection is secure Remove the suction head from the fixed gun assembly, fit in the air jet, re-connect the suction head and tighten. Loosen the M6 screw on the side of the gun and install the corresponding blast nozzle (orifice size should be twice the size of the air jet), tighten the screw Connect the side branch of the gun assembly with a suction hose. Connect the rear inlet of the gun to the flexible metal hose in the cabinet, screw until secure Connect the other end of the suction hose to the corresponding suction pipe Connect one end of the high pressure air hose to the air connector on the right side of the electrical control box, the other end to the air inlet on the movable gun, secure with hose clamps Connect one end of the suction hose to the side branch of the movable gun assembly, the other to the fixed suction pipe Installation of the air jet and nozzle are the same as the fixed gun assembly. 3.0 OPERATING INSTRUCTIONS 3.1 Cabinet Operation Assemble and install the blast cabinet as detailed in Section 2.0 of this manual The air jet should be approximately half the size of the nozzle Pour abrasive media approximately 18 kg (40lb) into the cabinet hopper through the side door of the cabinet Turn on the compressed air supply, when the air pressure reaches 415 Kpa (60 PSI), press the power switch to ON, the power indicator should then light up.! WARNING! NEVER EXCEED MAXIMUM OPERATING PRESSURE OF 125PSI (8.6BAR), AS THIS MAY RESULT IN SERIOUS INJURY OR DEATH The machine comes with two (2) blasting guns, but under the control of an electric/pneumatic system where only one gun is operable at any one time. When the movable gun and door closed indicators on the control panel are illuminated then the movable gun is available for operation. Step on the pedal switch and the movable gun shuts down and the fixed gun operates immediately, this will be seen on the control panel indicators There are limit switches located inside each door to sense when the doors are open or closed. If the door closed indicator on the control panel is not illuminated, the system is then in a protection mode and the fixed gun will not operate When the air pressure exceeds 60 PSI, the user can operate the machine. First insert arms into the rubber gloves, grasp the work piece to be blasted, position it under the fixed gun, step on the pedal switch and then the blasting process begins. Alternately grasp the movable gun, point the nozzle at the work piece, press the trigger and the blasting process begins, check the work piece to ensure the desired result has been obtained The abrasive media will drop into the bottom of the cabinet hopper to be recycled during the blasting process. Note: To ensure reliable blasting the compressed air should be dry, if it contains too much moisture, a moisture separator should be installed immediately before the air enters the connection to the control box. 3.2 Illumination and Electro-Pneumatic System - 2 -

5 3.2.1 The pneumatic system is controlled by an electric circuit, which is set inside the control box located on top of the cabinet. A layout of the front panel of the box is shown below in Figure Control Panel Functions and Indicators Item 1 Fuse - A safety feature for overload and short circuit protection Item 2 Power switch - To connect or disconnect the power supply Item 3 Light switch - To turn the cabinet light on or off Item 4 Power indicator Illuminates when the power supply is connected Item 5 Door closed indicator - Illuminates when the doors are closed and fixed gun is operable Item 6 Fixed gun indicator - Illuminates when the fixed gun is in operation Item 7 Movable gun indicator - Illuminates when the movable gun is operable or in operation Item 8 Air pressure gauge - Indicates blasting air pressure Item 9 Air pressure valve - Regulates the blasting air pressure, turn clock wise and pressure increases, turn counter clock wise and pressure decreases Item 10 Pedal switch - Controls operation of the fixed gun Item 11 Electro-magnetic valve - Controls the selection of the blasting mode required. 3.4 Electric Control Box Note: If the control system breaks down or malfunctions have it repaired by a qualified technician. 3.5 Control of the Blasting Action Choose a nozzle and air jet of suitable size according to the desired grade of fineness or coarseness of surface finish required. Also check the air volume required for the nozzle at the required blasting pressure against the compressed air supply available Use a suitable grade of abrasive to achieve the desired surface finish The operator should now manipulate the blast gun or work piece to move the blasting action over the surface of the component being blasted, until the desired result is achieved. Smooth, continuous strokes over the component surface are normally the most effective, with the nozzle being held approximately 75mm (3 ) to 125mm (5 ) from the component surface The air pressure should remain stable during blasting Ensure there is good lighting of the cabinet work area To stop the blasting action, the operator, in the case of the movable gun releases the gun trigger, and in the case of the fixed gun changes the mode by depressing the foot pedal Allow a few moments for the fan and dust collector to clear the airborne dust from the cabinet before opening the cabinet door and removing the blasted component(s) Close the door, shut off the compressed air supply, and switch off the cabinet light and dust collector fan assembly and power supply Connect the power cord on the rear panel to a grounded power supply Press the power switch to ON, the power indicator will immediately light up, if not, check the power supply and cord, also check the fuse has not blown. Replace with fuse of the same rating Press the light switch ON, the light will illuminate immediately The door status tester is a feature designed to protect the operator and surrounding environment from the abrasive blasting process if a door should be inadvertently opened. When the door-closed indicator is illuminated, it indicates the doors are securely closed and the fixed gun is operable under the control of the pedal switch. Note: Never operate the blast system with any of the cabinet doors open, as serious injury may occur

7 4.0 MAINTENANCE Note: Always ensure both the compressed air supply and electrical power supply has been isolated from the cabinet prior to carrying out any maintenance. Over a period of time, dust and debris will build up in the abrasive mix, which will cause a loss of blasting performance, poor visibility in the cabinet and poor surface finish. The abrasive should be drained from the cabinet and new clean abrasive loaded into the cabinet. 4.1 Suction Gun Assembly On a monthly basis, remove the blast nozzles from both the fixed and movable guns, and inspect both nozzles and air jets for wear. If an air tip is worn sufficiently to have either worn through completely, or caused damage to the air tip discharge opening, it should be replaced. 4.5 Cabinet Window Over a period of time, the cabinet viewing window cover will become frosted by the impact from rebounding abrasive. The window cover can be replaced. Peel the cover from the window, and then clean the dust from the inside surface of the window using a non-oil based cleaning solvent. Remove the protective backing tape from the new window cover, and attach it to the inside surface of the window. 4.6 Rubber Seals On a weekly basis, inspect the main cabinet door seal around the door opening for wear and damage. Also inspect the abrasive hopper seal and the dust collector inspection door seal for wear and damage. Replace all seals as required If a blast nozzle is worn by 1mm (0.040 ) or more from its original size or the internal surface is grooved or damaged, then the blast nozzle should be replaced. 4.2 Blast Hose On a monthly basis, inspect the abrasive supply hose along its length by feeling for soft spots, which will indicate areas of wear, replace as required. 4.3 Dust Collector On a weekly basis, or when the visibility within the cabinet becomes poor, with the dust collector fan turned off, operate the dust filter rapping device for approximately seconds to shake the dust build up from the dust filter. Wait a few moments for the dust to settle, then open the drain valve on the bottom of the dust collector and drain the dust into a refuse dustbin. When all the dust has completely drained out, close the drain valve After every five (5) hours of operation, or If the visibility in the cabinet continues to be inadequate after the dust collector filter has been rapped, it may be necessary to remove the filter cartridge from the dust collector, and blow it down from the inside out, with compressed air. Be careful not to damage the filter cartridge media while blowing down, and do not attempt to wash the filter cartridge with water or any other fluid If blowing the filter cartridge down with compressed air does not clean it adequately, or dust is discharged from the dust collector outlet, the filter cartridge should be replaced. 4.4 Cabinet Gloves On a weekly basis, give the cabinet gloves a visual inspection and check for holes and signs of deterioration. Replace the gloves as necessary
