Safety Information
Always observe the following safety precautions to reduce the risk of electric shock, fire, or serious injury:
- Read All Instructions: Familiarize yourself with the compressor's controls and proper usage.
- Eye Protection: Always wear ANSI Z87.1 approved safety glasses with side shields when operating the compressor or air tools.
- Hearing Protection: This compressor operates at 78 decibels. Prolonged exposure to noise levels above 70 dB can cause hearing damage. Wear appropriate hearing protection.
- Electrical Safety: Connect the compressor only to a grounded 120 Volt, 60 Hz AC outlet. Do not use extension cords unless absolutely necessary, and ensure they are rated for the compressor's power requirements.
- Ventilation: Operate the compressor in a well-ventilated area. Do not block air vents.
- Moisture: Do not operate the compressor in wet or damp conditions, or expose it to rain.
- Pressure Limits: Never exceed the maximum pressure rating of any air tool or accessory.
- Disconnect Power: Always disconnect the power supply before performing any maintenance, adjustments, or when the compressor is not in use.
- Keep Clear: Keep children and bystanders away from the operating area.
- Hot Surfaces: The compressor motor and pump can become hot during operation. Avoid contact with these areas.

Figure 2: Component Diagram
- Flip-up Handle: For easy carrying and storage.
- Oil-Free Pump: Requires no oil changes, reducing maintenance.
- Tank Pressure Gauge: Displays the internal pressure of the air tank.
- Outlet Pressure Gauge: Displays the regulated air pressure being supplied to the air tool.
- Large Regulator Knob: Used to adjust the output air pressure.
- Quick Coupler: For quick and secure connection of air hoses and tools.
- Rubber Feet: Provide stability and reduce vibration during operation.
Setup
- Unpacking: Carefully remove the compressor from its packaging. Inspect for any shipping damage. Report any damage to the retailer immediately.
- Placement: Position the compressor on a firm, level surface. Ensure there is adequate space around the unit for ventilation.
- Power Connection: Verify that the power switch is in the "OFF" position. Plug the compressor's power cord into a standard grounded 120V, 60Hz electrical outlet.
- Initial Check: Before first use, ensure all connections are secure and the drain valve at the bottom of the tank is fully closed.
Operating Instructions
Basic Operation
- Power On: Flip the power switch to the "ON" position. The compressor will begin to run and fill the air tank.
- Monitor Tank Pressure: Observe the tank pressure gauge. The compressor will automatically shut off when the tank reaches its maximum pressure (110 PSI). It will restart automatically when the tank pressure drops below a preset level.
- Adjust Output Pressure: Before connecting an air tool, turn the large red regulator knob to set the desired working pressure. Turn clockwise to increase pressure, counter-clockwise to decrease. The outlet pressure gauge will display the set pressure.
- Connect Air Tool: Attach your air hose and tool to the quick coupler. Ensure a secure connection.
- Power Off: When you have finished using the compressor, turn the power switch to "OFF" and disconnect the power cord from the outlet.
Applications
This ECOMAX air compressor is suitable for a variety of tasks, including:
- Tire inflation for vehicles, bicycles, and recreational equipment.
- Operating brad nailers (18 gauge) and finishing nailers (16 gauge).

Maintenance
Regular maintenance ensures optimal performance and extends the life of your air compressor.
- Oil-Free Pump: This compressor features an oil-free pump, which means no oil changes are required. This design reduces routine maintenance.
- Drain Air Tank: Moisture accumulates in the air tank during operation. To prevent rust and corrosion, drain the tank daily or after each use. Locate the drain valve at the bottom of the tank, open it to release condensed water, and then close it securely.
- Cleaning: Keep the compressor's exterior clean. Wipe down surfaces with a dry cloth. Ensure air vents are clear of dust and debris to prevent overheating.

Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not start or stops unexpectedly. | No power, power switch off, circuit breaker tripped, thermal overload. | Check power connection. Ensure switch is ON. Reset circuit breaker. Allow compressor to cool if thermal overload engaged. |
| Low air pressure or slow recovery. | Air leaks in hose/fittings, regulator set too low, tool requires more SCFM than compressor provides. | Check all connections for leaks. Adjust regulator knob to increase pressure. Verify tool's air requirements. |
| Excessive noise during operation. | Normal operation noise (78 dB), loose components, unstable surface. | Ensure compressor is on a stable, level surface. Check for any loose parts. If noise is unusual, contact support. |
| Compressor runs continuously. | Air leak in tank or connections, faulty pressure switch. | Check for air leaks. If problem persists, professional service may be required. |
