2. Safety Information
Read and understand all safety warnings and instructions before operating this air compressor. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.
General Safety Warnings
- Work Area Safety: Keep the work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Electrical Safety: This compressor operates on 115V. Ensure the power source matches the compressor's requirements. Avoid using extension cords unless absolutely necessary, and ensure they are rated for outdoor use and the correct amperage.
- Personal Safety: Always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and gloves. Do not overreach; maintain proper footing and balance at all times.
- Compressor Use and Care: Do not modify the compressor. Use the correct compressor for your application. Do not abuse the power cord. Never carry the compressor by the cord or yank it to disconnect from the receptacle.
- Pressure Safety: Never exceed the maximum operating pressure of any air tool or accessory. Always drain the air tank daily to prevent rust and maintain tank integrity.
3. Setup
Unpacking and Inspection
- Carefully remove the compressor from its packaging.
- Inspect the unit for any damage that may have occurred during shipping. If damage is found, contact your retailer immediately.
- Ensure all components listed in the packing list are present.

5. Maintenance
Regular maintenance ensures the longevity and safe operation of your air compressor.
Daily Maintenance
- Drain the Air Tank: Open the drain valve at the bottom of the tank to release any accumulated moisture. This prevents rust and corrosion inside the tank.
- Inspect for Leaks: Check all connections and hoses for air leaks. Tighten any loose fittings.
Periodic Maintenance
- Clean the Air Filter: The oil-free pump design means no oil changes are required. However, regularly inspect and clean the air filter to ensure proper airflow and prevent debris from entering the pump.
- Check Fasteners: Periodically check all nuts, bolts, and screws for tightness.
- Inspect Power Cord: Examine the power cord for any signs of damage, fraying, or cuts. Replace if necessary.
Storage
- Before storing, ensure the tank is completely drained of air and moisture.
- Store the compressor in a clean, dry location, protected from extreme temperatures.
