2. Important Safety Information
WARNING: Failure to read and follow the operator's manual, all warnings, and operating instructions could result in death or serious injury.
2.1 Risk of Bursting
- Ensure the compressor outlet pressure is set lower than the maximum pressure rating of the spray gun or tool being used. Do not exceed 125 PSI.
- Do not weld or drill into the air tank. Any modification to the tank can compromise its structural integrity.
- Drain water from the tank after each use to prevent corrosion and maintain tank integrity.
2.2 Risk of Fire or Explosion
- Do not spray flammable or combustible liquids or paints near sparks, flames, pilot lights, or other ignition sources.
- Operate the compressor in a well-ventilated area. Keep the compressor at least 20 feet away from the spray area.
- Do not smoke while operating the compressor or using air tools.
2.3 Risk of Electric Shock
- Always connect the compressor to a properly grounded outlet.
- Do not operate the compressor in wet conditions or with wet hands.
2.4 Risk of Moving Parts
- Keep hands, feet, and clothing away from moving parts.
- Ensure the compressor is turned off and unplugged before performing any maintenance.

4. Setup
Follow these steps to set up your air compressor for first use:
- Unpacking: Carefully remove the compressor from its packaging. Inspect for any shipping damage.
- Placement: Place the compressor on a firm, level surface in a clean, well-ventilated area. Ensure the rubber feet are making full contact with the surface to minimize vibration.
- Power Connection: Connect the 6-foot power cord to a grounded 120-volt AC outlet. The compressor is designed for an easy cold start, requiring only 2.8 amps.
- Attach Air Hose: Connect your air hose to the quick connect coupler on the compressor. Ensure a secure connection.
- Attach Air Tool: Connect your desired air tool (e.g., nailer, drill, inflator) to the other end of the air hose.

5. Operating Instructions
Operating your STEALTH SAUQ-1105 Air Compressor is straightforward:
- Power On: Turn on the compressor using the power switch. The motor will start and begin to fill the tank. The tank gauge will show the increasing pressure.
- Set Pressure: Once the tank is full (up to 125 PSI), use the air pressure regulator knob to set the desired working pressure for your tool. Observe the tool gauge to ensure the correct pressure is set.
- Begin Work: You can now operate your air tool. The compressor will automatically cycle on and off to maintain the set pressure in the tank as you use air.
- Applications: This compressor is suitable for various tasks including:
- Drilling: Powering air drills for various materials.
- Nailing/Brad Nailing: Ideal for finishing nailers and brad nailers for trim work and small projects.
- Grinding: For light grinding tasks with appropriate air grinders.
- Inflation: Inflating tires, sports equipment, and other inflatables.
- Power Off: When finished, turn off the compressor and disconnect the air hose and tools.

6. Maintenance
The STEALTH SAUQ-1105 features an oil-free pump, significantly reducing maintenance requirements. However, regular care is still essential for optimal performance and longevity:
- Drain Tank Daily: After each use, or at least daily, open the drain valve at the bottom of the tank to release any accumulated moisture. This prevents rust and extends the life of the tank.
Figure 6.1: The drain valve is used to remove moisture from the air tank after the compressor is shut off.
- Clean Air Filter: Periodically check and clean the air filter to ensure proper airflow and prevent dust from entering the motor.
- Inspect Hoses and Connections: Regularly check air hoses for cracks or leaks and ensure all connections are tight.
- Store Properly: Store the compressor in a clean, dry environment when not in use.
7. Troubleshooting
If you encounter issues with your STEALTH SAUQ-1105 Air Compressor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not start. | No power; Thermal overload activated; Faulty switch. | Check power connection and outlet; Allow compressor to cool down and press reset button; Contact support. |
| Compressor runs continuously or cycles too frequently. | Air leak in hose or connections; Drain valve open; Pressure switch malfunction. | Check all connections for leaks and tighten; Ensure drain valve is closed; Contact support. |
| Low air pressure at tool. | Regulator set too low; Air leak; Tool requires more CFM than compressor provides. | Adjust regulator to higher pressure; Check for leaks; Ensure tool is compatible with compressor's CFM output. |
| Excessive noise or vibration. | Loose components; Uneven surface; Damaged motor/pump. | Check and tighten any loose parts; Place on a firm, level surface; Contact support if noise persists. |
