4.1 Pornirea compresorului
- Ensure all connections are secure and the power supply is connected.
- Open the air outlet valve slightly to allow the compressor to start without full load.
- Turn on the main power switch. The compressor will start automatically and build pressure.
- Once the desired pressure is reached, the compressor will shut off automatically due to the auto start/stop pressure switch operation.
4.2 Reglarea presiunii
The operating pressure can be adjusted using the pressure regulator, typically located near the pressure gauge. Turn clockwise to increase pressure and counter-clockwise to decrease pressure. Monitor the pressure gauge during adjustment.
4.3 Închidere
- Opriți întrerupătorul principal.
- Close the air outlet valve.
- Bleed any remaining air pressure from the tank using the manual condensate drain or an air tool connected to the outlet.
5. Întreținere
Regular maintenance is crucial for the longevity and efficient operation of your air compressor.
5.1 Întreținere zilnică
- Drain Condensate: Open the manual condensate drain valve at the bottom of the tank to release accumulated moisture. Close the valve once all water has been expelled.
- Verificați nivelul uleiului: Verify the oil level in the compressor pump.
5.2 Întreținere săptămânală
- Inspectați filtrul de aer: Check the air filter for dirt and debris. Clean or replace if necessary.
- Inspectați curelele: Examine drive belts for wear, cracks, or proper tension. Adjust belt tension as needed; easy access is provided for this adjustment.
5.3 Monthly/Quarterly Maintenance
