Bormann Pro Sandblaster

Safety Instructions

Before opening the tank:

1. Release the air pressure on the sand tank by turning off the air supply valve (19) and opening the nozzle valve (19C).
2. Ensure the tank pressure gauge (16) reads zero before opening the tank.

Maintain correct air pressure:

• Pressure should not exceed 125 PSI. If it does, the safety valve (11) should release excess pressure. If not, stop work immediately and use the air compressor to reduce pressure. Do not investigate pressure problems until the gauge reads zero.

Assembling the Sandblaster

Follow the step-by-step diagrams for assembly:

1. Step 1: Assemble the intake manifold (15). Attach the pressure gauge (16) to the top of the manifold, ensuring it's visible. Attach the throttling valve (9A) to the bottom of the manifold. Connect the nipple connector (21) to the throttling valve and the joint pipe (14) to the manifold.
2. Step 2: Assemble the water trap filler (18). Screw two nipple connectors (17) into each side of the filler. Attach the air supply valve (19) to one nipple connector and the male/female connector (20) to the other side of the air supply valve. The air hose from the compressor will connect to the male/female connector (20).
3. Step 3: Place the tank (01) on a table with the four clips up. Screw the water trap filler (18) and its parts into the side of the intake manifold. Screw the open end of the joint pipe (14) with the intake manifold (15) and pressure gauge (16) attached into the threaded hole on the side of the filler pipe on top of the tank. Ensure the manifold and gauge are vertical.
4. Step 4: Assemble the sand outlet valve into the hole at the bottom of the tank. Attach the nipple connector (17), sand metering valve (19B), nipple connector (17), and sand outlet pipe (23) in order.
5. Step 5: Assemble the nozzle shut-off valve (19C). Select one of the four nozzles (28). Screw the adapter (26) into the nozzle shut-off valve (19C). Screw the last nipple connector (17) into the other side of the valve. Add the gasket (27) to the nipple connector, then attach a nozzle (28) and the nozzle cap nut (29).
6. Step 6: Connect the sand metering valve assembly (step 4) and the nozzle shut-off assembly (step 5). Slide hose clamps (24) over each end of the sand hose (25). Connect one end of the hose to the nipple on the sand outlet pipe (23) and the other end to the adapter (26). Ensure both hose ends are firmly seated on the nipples. Tighten the hose clamps firmly.
7. Step 7: Fasten the two handlebars (06) to the tank using four pan screws (08), four washers (10), and four hex nuts (09). Keep the handle curve ends upward.
8. Step 8: Slide the axle (05) through the holes in the handlebars (06). Place one wheel (02) at each end of the axle and fasten them with copper pills (03) and washer (30).
9. Step 9: Insert the fitted foot (04) onto the fitting on the top of the tank near the edge. Use the last copper pin (03) to hold the foot to the tank.
10. Step 10: Double-check all connections to ensure they are tight and properly seated before operating.

Abrasive Selection

The type of sand used affects cleaning time. Common abrasives include silicon carbide, alumina, silica sand, bank sand, and beach sand. Bank and beach sands may contain shells, coral, and organic materials that absorb moisture more readily, potentially clogging the sand metering valve. Reused sand wears down and becomes less effective over time.

Loading Abrasives into the Tank

1. Ensure abrasive is dry and will not clog the meter valve (19B), sand outlet pipe (23), hose (25), or other components.
2. Wear protective clothing.
3. Turn the air supply valve (19) to the off (horizontal) position.
4. Open the nozzle shut-off valve (19C) (vertical position).
5. Watch the pressure gauge (16) to ensure it reads zero.
6. Remove the filler cap (13) from the top of the tank.
7. Insert the funnel (30) and pour abrasive into the funnel. Fill the tank 3/4 full for large jobs and reload as needed.
8. If humidity is high (90-100%), reduce abrasive load and empty the water trap more often to prevent clogging.
9. Close the filler cap (13) after adding abrasive.
10. Close the nozzle shut-off valve (19C) and open the air supply valve (19).
11. Check for air leaks at the filler cap as you pressurize the tank.

Maintenance

Protect your air compressor by keeping it in a separate room with a long hose, or position it upwind from the sandblaster. Continue standard compressor maintenance procedures.

Parts that carry the air/abrasive mixture, such as the sand hose (25), fittings, shut-off valve (19C), and nozzles (28), will wear faster. Inspect for air leaks and replace worn parts immediately. Blisters in the hose indicate thinning walls and require replacement.

Air Supply Requirements

Sandblasting requires high air volume and pressure. Insufficient hose size, air pressure, or an oversized nozzle can reduce efficiency.

For best results, air pressure should be between 65-125 PSI.

Important Safety Instructions

• Keep the work area clean and well-lit.
• Do not use in damp, wet, or poorly lit locations. Keep compressors away from flammable gases or liquids.
• Keep children and unauthorized personnel away from the work area.
• Wear appropriate protective clothing, including a hood (not included), dust mask, and heavy-duty gloves.
• Periodically inspect sand-carrying components for wear.
• Secure the workpiece with clamps or a vise.
• Maintain proper footing and balance.
• Maintain tools carefully, following lubrication and component replacement instructions.
• Disconnect air compressor power when not in use, before servicing, or when changing components.
• Ensure the nozzle valve is in the off position when not in use to avoid unintentional starting.
• Stay alert and use common sense. Do not operate when tired.
• Use only identical replacement parts for servicing.
