Operating Instructions
Operating your Master Airbrush TC-20 compressor is straightforward:
- Power Connection: Plug the power cord into a standard 120V AC electrical outlet.
- Power On: Flip the power switch to the 'ON' position. The compressor will begin to build pressure.
- Automatic Shut-off: The compressor features an automatic on/off shut-off. It will stop running once the maximum pressure is reached and restart automatically when the pressure drops due to airbrush use.
- Pressure Adjustment: The regulator allows you to adjust the output air pressure. Turn the knob on top of the regulator clockwise to increase pressure and counter-clockwise to decrease it. Monitor the pressure gauge for the desired setting.
- Connect Airbrush: Connect your airbrush to the free end of the air hose. Ensure the connection is secure.
- Begin Airbrushing: Once the desired pressure is set and your airbrush is connected, you can begin your airbrushing task.
- Power Off: When finished, turn the power switch to the 'OFF' position and unplug the unit.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your compressor:
- Drain Water Trap: The water trap filter collects moisture from the air. Regularly drain any accumulated water by pressing the release valve at the bottom of the filter bowl. This should be done after each extended use or when water is visible.
- Clean Exterior: Wipe down the exterior of the compressor with a damp cloth to remove dust and paint residue. Do not use harsh chemicals or abrasive cleaners.
- Air Filter: The compressor is equipped with an air filter. Check it periodically for dust and debris. Clean or replace the filter as needed to maintain airflow.
- Storage: Store the compressor in a clean, dry environment when not in use. Disconnect the air hose and power cord.
