3. Setup and Initial Preparation
Before first use, ensure all components are present and the compressor is prepared correctly.
Unpacking and Inspection
- Carefully remove the compressor from its packaging.
- Inspect the unit for any shipping damage. If damage is found, do not operate the compressor and contact your supplier.
- Verify that all included components, such as wheels, handles, and oil, are present.
Attaching Wheels and Handle (if not pre-assembled)
- Attach the wheels to the compressor base using the provided hardware.
- Secure the handle to the designated mounting points.
Adding Compressor Oil
The compressor is supplied with oil. It is crucial to add the oil before first operation.
- Locate the oil filler cap/dipstick on the pump housing.
- Remove the cap and carefully pour the supplied compressor oil into the reservoir until the oil level reaches the mark on the dipstick or sight glass. Do not overfill.
- Replace the oil filler cap securely.
Electrical Connection
- Ensure the power switch is in the "OFF" position.
- Connect the power cord to a grounded 220-240V electrical outlet.
- Avoid using extension cords if possible. If an extension cord is necessary, ensure it is rated for the compressor's power requirements and is of adequate gauge.
4. Operating Instructions
Follow these steps for safe and effective operation of your Ingco air compressor.
Starting the Compressor
- Ensure the drain valve at the bottom of the tank is closed.
- Connect your air tool or hose to the quick-connect coupler.
- Turn the power switch to the "ON" position. The compressor will start and build pressure until it reaches its maximum pressure (8 bar), then it will shut off automatically.
- Adjust the regulated air pressure using the pressure regulator knob, if your application requires less than maximum pressure.
Using Air Tools
- Always refer to the air tool's instruction manual for its specific pressure requirements.
- Ensure the air hose and connections are secure before operating.
- When finished, turn off the compressor and bleed any remaining air pressure from the tank and hose.
Stopping the Compressor
- Turn the power switch to the "OFF" position.
- Disconnect the compressor from the power supply.
- Slowly open the drain valve at the bottom of the air tank to release all air pressure and drain any accumulated condensation. Close the valve after draining.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your compressor.
Daily Maintenance
- Drain Air Tank: After each use, drain condensation from the air tank. This prevents rust and corrosion.
- Check Oil Level: Before each use, check the oil level using the dipstick. Add oil if necessary.
Weekly/Monthly Maintenance
- Clean Air Filter: Inspect and clean the air filter. A clogged filter reduces compressor efficiency. Replace if damaged.
- Inspect for Leaks: Check all air connections and hoses for leaks. Tighten or replace as needed.
Oil Change
Change the compressor oil after the first 20 hours of operation, then every 100-200 hours or every 3 months, whichever comes first. Use only recommended compressor oil.
- Ensure the compressor is off, unplugged, and the tank is depressurized.
- Place a suitable container under the oil drain plug.
- Remove the oil drain plug and allow the old oil to drain completely.
- Replace the drain plug and refill with new compressor oil to the correct level.
- Dispose of used oil responsibly.
