- Pressure Regulator: Knob to adjust the output air pressure.
- Quick Connect Coupler: For attaching air hoses and tools.
- Roll Cage Handle: Provides protection and a convenient grip for transportation.
- Air Tank: 2-gallon capacity for compressed air storage.
- Drain Valve: Located at the bottom of the tank for moisture removal.
5. Setup
Follow these steps for initial setup:
- Unpacking: 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 there is adequate space around the unit for air circulation.
- Power Connection: Ensure the power switch is in the OFF position. Connect the power cord to a grounded electrical outlet that meets the voltage requirements (90 Volts). The compressor is designed to operate on a 16 gauge, 275 ft. extension cord if needed.
- Initial Break-in (First Use):
- Open the drain valve at the bottom of the air tank.
- Turn the pressure regulator knob counter-clockwise to the lowest setting.
- Turn the compressor ON. Allow it to run for 15-20 minutes with the drain valve open. This helps to break in the motor and pump components.
- After the break-in period, turn the compressor OFF, close the drain valve, and allow the unit to cool.
6. Operating Instructions
Operating your EXCELL SAC22HPE Air Compressor:
- Prepare for Operation:
- Ensure the drain valve is closed.
- Connect your air hose to the quick connect coupler.
- Connect your air tool to the other end of the hose.
- Start the Compressor: Turn the power switch to the ON position. The compressor will run until the tank reaches its maximum pressure (125 PSI), then it will shut off automatically. It will restart when the tank pressure drops.
- Adjust Output Pressure: Turn the pressure regulator knob clockwise to increase the output pressure to your tool, or counter-clockwise to decrease it. Monitor the tool pressure gauge to set the desired PSI for your application.
- Using Air Tools: Operate your air tool according to its specific instructions.
- Shutting Down:
- Turn the power switch to the OFF position.
- Disconnect the air hose and tool.
- Slowly open the drain valve to release any remaining air pressure from the tank.
- Once all air is released, close the drain valve.
7. Maintenance
The EXCELL SAC22HPE features an oil-free pump, significantly reducing maintenance requirements. However, regular checks are still necessary to ensure optimal performance and longevity.
Daily Maintenance:
- Drain Air Tank: After each use, or at the end of each workday, drain moisture from the air tank by opening the drain valve. This prevents rust and corrosion inside the tank.
Weekly/Monthly Maintenance:
- Clean Exterior: Wipe down the compressor's exterior with a damp cloth to remove dust and debris.
- Inspect Air Filter: Check the air intake filter for excessive dirt or blockage. Clean or replace if necessary to ensure proper airflow.
- Check for Leaks: Listen for any air leaks around fittings and connections. Tighten as needed.
- Inspect Power Cord: Examine the power cord for any cuts, fraying, or damage. Replace if damaged.
Note: This compressor is equipped with an oil-free pump and does not require oil changes or lubrication of the pump mechanism.
8. Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not start | No power supply Power switch OFF Thermal overload activated | Check power connection and outlet Turn power switch ON Allow compressor to cool down, then reset |
| Low air pressure at tool | Regulator set too low Air leaks in hose/fittings Air tool requires more CFM than compressor provides | Adjust regulator clockwise Check and tighten connections, replace damaged hose Ensure tool CFM requirements are within compressor's capacity |
| Compressor runs continuously or too frequently | Air leaks in tank or connections Heavy air demand from tool | Check for leaks with soapy water, tighten or repair Use tools with lower CFM requirements or allow compressor to catch up |
| Excessive noise or vibration | Loose components Unit not on a level surface | Check and tighten all fasteners Place on a stable, level surface |
| Moisture in air line | Tank not drained regularly | Drain tank after each use. Consider an in-line air dryer for sensitive applications. |
