Introduction

This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your 20 Lb. Pressurized Abrasive Blaster. Please read this manual thoroughly before use and retain it for future reference.

Safety Information

General Safety Warnings

• Always wear appropriate personal protective equipment (PPE), including eye protection, respiratory protection, and gloves, when operating the abrasive blaster.
• Ensure the work area is well-ventilated to prevent accumulation of dust and abrasive particles.
• Never point the nozzle at yourself or others.
• Disconnect the air supply before performing any maintenance or adjustments.
• Do not exceed the maximum recommended working pressure.
• Use only dry, clean abrasive media. Moisture can cause clogging and reduce performance.
• Keep children and bystanders away from the operating area.
• Read and understand all instructions before operating the unit.

Setup

1. Unpacking: Carefully remove all components from the packaging. Inspect for any shipping damage.
2. Assembly:
   • Attach the hose to the blaster unit and the nozzle assembly. Use PTFE tape on all threaded connections to ensure an airtight seal.
   • Ensure all connections are tight before pressurizing the unit.
3. Abrasive Media Loading:
   • Ensure the unit is depressurized before loading media.
   • Use the provided funnel to carefully pour up to 20 lbs. of dry, clean abrasive media (e.g., silica, silicon carbide, aluminum oxide) into the tank.
   • Do not overfill.
4. Air Supply Connection:
   • Connect a 1/4 inch-18 NPT air hose from your air compressor to the blaster's air inlet.
   • Ensure your air compressor can provide the required air consumption: 6 CFM @ 60 PSI, 25 CFM @ 125 PSI.
   • A moisture separator is included and should be used to prevent moisture from entering the tank.

Operating Instructions

1. Preparation:
   • Wear all necessary PPE.
   • Prepare the surface to be blasted, ensuring it is clean and free of loose debris.
   • Ensure the work area is clear of obstructions and well-ventilated.
2. Pressurizing the Unit:
   • Close all valves on the blaster unit.
   • Slowly open the air supply valve from your compressor.
   • Monitor the pressure gauge (if equipped) and ensure the working pressure is between 60-125 PSI. The safety valve will activate if pressure exceeds safe limits.
3. Blasting Operation:
   • Point the nozzle at the target surface.
   • Gradually open the abrasive media shut-off valve. There are four different shut-off valve locations for adjusting media flow.
   • Begin blasting. Adjust air pressure and media flow as needed for optimal performance.
   • Maintain a consistent distance and angle for even abrasive removal.
4. Shutting Down:
   • Close the abrasive media shut-off valve.
   • Close the air supply valve from your compressor.
   • Slowly open the pressure relief valve to depressurize the tank.
   • Once depressurized, disconnect the air supply.

Maintenance

• After Each Use:
  • Depressurize the unit completely.
  • Empty any remaining abrasive media from the tank to prevent moisture absorption and clogging.
  • Clean the nozzle and hose to remove any abrasive residue.
• Regular Maintenance:
  • Inspect the hose for cracks, kinks, or wear. Replace if damaged.
  • Check all connections for leaks. Tighten or re-tape as necessary.
  • Periodically inspect the safety valve to ensure it is free from obstructions and functions correctly.
  • Drain moisture from your air compressor's tank regularly.
• Storage:
  • Store the abrasive blaster in a dry, clean environment, away from extreme temperatures.
  • Ensure the tank is empty and depressurized before storage.
