• Always wear personal protective gear.
• Fire or Explosion Hazard! DO NOT USE a media blaster around combustible or
  flammable liquids, dusts, gases, oily rags, or other materials that can explode or burn quickly. Some abrasives create sparks when they hit metal. Abrasives similar to aluminium oxide may generate static electricity sparks which may cause fires or explosions in an unsafe environment.

ASSEMBLY, OPERATION & PREVENTATIVE MAINTENANCE

1. FEATURES
   The Red Label mobile sandblasting unit is supplied with 2.4m rubber hose, four ceramic nozzles and in-line water trap for moisture-free grit blasting. Also includes bayonet air-line coupling and air flow regulator. Accepts a variety of grits up to 80microns and is suitable for stripping rust and paint from wheels, chassis, panels and other corroded/painted surfaces.

2. ASSEMBLY

3. Step 1, assembling the intake manifold (15). First attach the pressure gauge (17) to the top of the intake manifold, turning the gauge so that it can be seen across the top of the tank. Next, attach the throttling valve (19A) to the bottom of the manifold. Attach the nipple connector (21), to the throttling valve. Attach the joint pipe (14) to the manifold.

4. Step 2, to assemble the water trap filter (18). Two nipple connectors (17) are screwed into each side of the filter. On one side, attach the air supply valve (18) to the nipple connector (17). Attach the male/female connector (20) to the other side of the air supply valve. When ready to operate the sandblaster, the air hose from the compressor will fasten to the male/female connector (20).

5. Step 3, place the tank (01) on a table with the four clips up. Screw the water trap filter (18) and its parts into the opening at the side of the intake manifold. Then screw the open end of the joint pipe (14) with intake manifold (15) and pressure gauge (17) attached into the threaded opening on the side of the filler pipe on top of the tank. Be sure that the manifold and gauge are vertical.

6. Step 4, assembly of the sand outlet valve into the opening at the bottom of the tank. Attach in order; nipple connector (17), sand metering valve (19B), nipple connector (17), and sand outlet pipe (25).

7. Step 5, fasten the handlebar (06) to the tank using four pan screws (08) four washers (50) and four hex nuts (09). Note: keep the handle curve ends upward.

8. Step 6, locate the axle (05) and slide it through the openings in the sides of the handlebar (06). Place one wheel (02) at each end of the axle and fasten them into place with cotter pins (03) and washer (51).

9. Step 7, insert the fixed foot onto the fitting on the bottom of the tank near the edge. Use the last cotter pin (03) to hold the foot to the tank.

10. Step 8, before operation go back over each connection, double checking to ensure that all are tight and properly sealed.

11. BEFORE USE
    Conduct a thorough visual inspection checking for leaks and any abnormal conditions, such as cracked welds, leaks, and damaged, loose, or missing parts.
    To protect your air compressor from damage it may receive from sandblasting
    • Keep the air compressor in a separate area, or
    • Always position the air compressor up-wind of the sandblasting area.

12. OPERATION
    Prior to each use always conduct a visual inspection checking for leaks and any abnormal conditions, such as cracked welds, leaks, and damaged, loose, or missing parts.
    Abrasive Selection:
    The type of media you choose will greatly influence the amount of time needed to clean a given surface area. Sandblasting materials include silicon carbide, alumina, bank sand and beach sand. However, bank and beach sand is not ideal, even if washed it will still contain shell, coral and organic materials. These absorb moisture much more readily than the other materials. As a result, the moisture in bank and beach sand frequently cause clogging of the sand metering valve.
    If you decide to re-use sand or media, remember it does wear out. The sharp edges become rounder, and are less effective. It’s at the point you should replace the batch of abrasive you are using.
    Loading Abrasive:
    • Check the abrasive is dry and won’t clog the meter valve (19B), sand outlet pipe (25), hose (24) or other components.
    • Always wear personal protective gear.
    • Turn the air supply valve (18) to the off (horizontal) position.
    • Open the blast gun nozzle (42) (vertical) position.
    • Ensure the pressure gauge (17) reads zero (“0 psi”) pressure.
    • Remove the filler cap (13) from the tip of the tank.
    • Insert the funnel (27) and pour the abrasive into the funnel. Be sure to load enough into the tank to do the job at hand. If it is a big job, fill the tank only ¾ full and reload as needed to finish the work.
    • Note: if the humidity is 90-100% the water trap (18) won’t be able to trap all of the moisture in a ¾ full tank. Reduce the amount of abrasive, load more frequently and empty the water trap frequently. This will reduce the possibility of clogging the bottom of the tank or line.
    • With the correct amount of abrasive in the tank close the filler cap (13).
    • Close the nozzle shut-off valve (42) and open the air supply valve (18).
    • Check for air leaks at the filler cap as you begin to pressurise the tank from the compressor.
    Correct Air Pressure:
    Pressure should not exceed 125psi. If pressure exceeds 125psi the safety relief valve (11) is designed to release the excess pressure. It this does not happen stop all work immediately and use the air compressor to reduce the excess pressure. Do not investigate the sandblaster’s pressure until the pressure gauge (16) reads zero.
    To Setup for Abrasive Blasting
    Note: Start with all valves in closed position.
    a Point the sandblasting gun to a safe direction away from people, pets or anything around you that may be damaged by abrasive spray.
    b Press and hold sandblasting gun until air starts flowing through the trigger
    c While pressing and holding the sandblasting gun, slowly open the abrasive control valve until abrasive material begins to flow out of the sandblasting gun
    d Adjust the abrasive valve to an appropriate position (about 45º) when desired amount of abrasive material is flowing through the trigger nozzle
    To Begin Blasting
    a Choose a larger nozzle for a broader spray pattern. Choose a smaller nozzle for more focussed abrasive blasting
    b Adjust abrasive flow with the abrasive control valve
    c Be aware of abrasive clogging the system. Depressurise if necessary and replace the abrasive media with drier or cleaner abrasive media
    To Stop Blasting
    a Whilst continuing to press and hold the sandblasting gun, turn the abrasive control valve to the closed position
    b When noticing only air is coming through the gun, stop the air flow by releasing the gun
    To Release Pressure from Tank
    a When finished blasting, point the sandblasting gun in a safe direction away from people, pets or anything around you that may be damaged by direct or indirect spray
    b Switch off power to the compressor
    c Turn the abrasive control valve to the closed position whilst pressing and holding the sandblasting gun to expel remaining abrasive material from abrasive hose
    d Release air pressure via the safety relief valve. Ensure gauge reads “0 psi”
    e Disconnect the air supply hose from the sandblasting unit
    Nozzle and Rubber Nozzle Replacement
    a Ensure air supply is disconnected from sandblaster
    b Whilst holding the sandblasting gun against spring pressure in the open position, unthread the knurled nozzle retaining collar of the sandblasting gun and remove the retaining collar, nozzle and seal
    c Insert the replacement nozzle into the retaining collar followed by the rubber seal, then thread the knurled nozzle retaining collar onto the sandblasting gun and tighten securely
    d Choose a larger nozzle for a broader spray pattern. Choose a smaller nozzle for a smaller more focussed abrasive blasting
    Health Considerations:
    • Protect yourself and those around you from ‘overspray’. Remember that your mobile sand blaster is shooting powerful spray of abrasive material
    • Do not point it at yourself or anyone around you
    • Always wear personal protective equipment
    • Wear a filter or mask over your mouth when operating this unit. You will create a cloud of abrasive material and debris which is dangerous to inhale
    • Remove, cover, and/or protect anything around you that might be damaged from direct or indirect contact with the abrasive spray or particles.

13. STORAGE
    This mobile sandblasting unit should always be stored in a dry indoor location on a level surface.

14. MAINTENANCE
    Before opening the tank release the air pressure on the sand tank;
    • Turn off the air supply valve (19);
    • Open the nozzle valve to release pressure in the line;
    • Ensure the tank pressure gauge (16) reads zero;
    • Open and empty the tank
    • Check for worn abrasive hose and fittings. The abrasive control valve, manifold and all parts after the abrasive is ejected from the tank are subject to rapid wear due to the flow of abrasive media. Check for leaks, blistering, bulging or thinness of the hose. Replace all parts which appear worn immediately.

15. SERVICE & REPAIR
