4. Setup Instructions
Follow these steps to set up your airbrushing system:
- Unpack Components: Carefully remove all items from the packaging and inspect for any damage.
- Position Compressor: Place the TC-320 Cool Runner II Air Compressor on a stable, level surface in a well-ventilated area. Ensure there is sufficient space around it for airflow.
- Attach Air Hose: Connect one end of the air hose to the air outlet on the compressor. Ensure a secure, airtight connection.
- Connect Airbrush: Attach the other end of the air hose to the air inlet of your chosen airbrush (G22, S68, or E91). Hand-tighten to prevent air leaks.
- Install Airbrush Holder: If using the universal clamp-on airbrush holder, secure it to your workbench or a stable surface. The compressor also has a built-in holder.
- Power Connection: Plug the compressor's power cord into a grounded electrical outlet.
- Initial Check: Before adding paint, turn on the compressor and check for any air leaks by listening for hissing sounds. Adjust connections if necessary.
5. Operating Instructions
5.1. Preparing Paint
- Always thin your paint to the consistency of milk for optimal airbrush performance.
- Use appropriate thinners recommended by the paint manufacturer.
- Strain paint through a fine mesh filter to remove any particles that could clog the airbrush.
5.2. Using the TC-320 Compressor
- Turn on the compressor using the power switch.
- Adjust the air pressure using the regulator knob. The gauge will display the current pressure.
- The compressor features an automatic on/off shutoff, activating when air is drawn and deactivating when not in use.
- The water trap filter collects moisture from the air. Regularly check and drain it as needed.
5.3. Airbrush Operation (General)
- Gravity Feed (G22): Pour prepared paint into the top-mounted fluid cup.
- Siphon Feed (S68, E91): Fill the siphon bottle with prepared paint and attach it to the airbrush.
- Dual-Action (G22, S68): Press the trigger down for air, then pull back for paint. This allows for fine control over both airflow and paint volume.
- Single-Action (E91): Press the trigger down for both air and paint. Paint volume is typically adjusted by a needle stop or by thinning.
- Practice on scrap material to get a feel for the airbrush and paint flow before working on your final project.
6. Maintenance
6.1. Airbrush Cleaning
Proper cleaning after each use is crucial for airbrush longevity and performance.
- Empty Paint: Remove any remaining paint from the fluid cup or siphon bottle.
- Flush with Cleaner: Fill the cup/bottle with appropriate airbrush cleaner or water (depending on paint type) and spray through the airbrush until clear.
- Back-Flush: For gravity feed airbrushes, cover the nozzle with a finger or cap and pull the trigger back to bubble cleaner into the cup, dislodging paint.
- Disassemble and Clean: For thorough cleaning, carefully disassemble the airbrush (needle, nozzle, air cap) and clean each part with a soft brush and cleaner. Be extremely careful with the needle and nozzle as they are delicate.
- Reassemble: Reassemble the airbrush, ensuring all parts are correctly seated and tightened.
6.2. Compressor Maintenance
- Drain Water Trap: Regularly drain accumulated moisture from the water trap filter at the bottom of the regulator.
- Keep Vents Clear: Ensure the compressor's cooling vents are free from dust and debris to maintain optimal cooling.
- Storage: Store the compressor in a clean, dry environment when not in use.
