Familiarize yourself with the main components of your compressor. Refer to Figure 1 for an overview of the unit's dimensions and general layout.

Assemblée

1. Fixez les roues : Securely attach the wheels to the compressor base using the provided hardware.
2. Attachez la poignée : Mount the transport handle to the designated points on the compressor body.
3. Positionnement : Place the compressor on a firm, level surface. Ensure there is adequate space around the unit for ventilation.

Connexion électrique

Connect the compressor to a suitable grounded power outlet. Ensure the power supply matches the voltage and frequency specifications of the compressor (typically 230V, 50Hz for this model). The unit is fitted with a 3-pin plug.

Initial Run-in Procedure

Before first use, or after extended storage, perform a brief run-in:

• Open the air outlet valve completely to allow air to escape freely.
• Switch on the compressor and let it run for approximately 15-20 minutes without building pressure. This helps to lubricate internal components.
• Switch off the compressor and close the air outlet valve.

Figure 3 : The pressure cut-out switch (black box with yellow warning label) and the red pressure regulator knob, along with the quick-connect air outlet.

• Pressostat : The black box (Figure 3) automatically turns the compressor on and off to maintain tank pressure.
• Manomètre de réservoir : Displays the current pressure inside the air tank (Figure 2).
• Working Pressure Gauge: Displays the pressure of the air being supplied to your tools, adjustable via the regulator (Figure 2).
• Régulateur de pression: The red knob (Figure 3) allows you to adjust the working pressure. Turn clockwise to increase pressure, counter-clockwise to decrease.
• Quick-Connect Air Outlet: For attaching air hoses and tools (Figure 3).

Démarrage du compresseur

1. Assurez-vous que la vanne de vidange située au bas du réservoir est fermée.
2. Branchez le compresseur sur une prise de courant appropriée.
3. Turn the main power switch to the "ON" position. The compressor will start to build pressure.
4. Once the tank reaches its maximum pressure, the compressor will automatically shut off.

Connecting and Using Air Tools

1. Connect your air hose to the quick-connect air outlet.
2. Attach your air tool to the other end of the hose.
3. Adjust the working pressure using the red regulator knob to suit the requirements of your air tool. Monitor the working pressure gauge.
4. Begin using your air tool. The compressor will cycle on and off automatically to maintain pressure as needed.

Fermeture

1. Mettez l'interrupteur principal sur la position « ARRÊT ».
2. Disconnect the air hose and tools.
3. Slowly open the drain valve at the bottom of the tank to release any condensed moisture and residual air pressure. Close the valve once the tank is empty.

Entretien

Un entretien régulier garantit la longévité et le fonctionnement sûr de votre compresseur d'air.

Quotidien/Après chaque utilisation

• Évacuer les condensats : After each use, or daily if used frequently, open the drain valve at the bottom of the air tank to release accumulated moisture. This prevents rust and corrosion inside the tank.

Weekly/Monthly

• Inspecter le filtre à air : Check the air filter for dirt and debris. Clean or replace if necessary to ensure proper airflow to the pump.
• Vérifiez les fuites : Listen for any air leaks around fittings, hoses, and valves. Tighten connections as needed. A soapy water solution can help identify small leaks.
• Inspecter les tuyaux et les raccords : Examine air hoses for cracks, cuts, or wear. Replace damaged hoses immediately. Ensure all quick-connect fittings are functioning correctly.
• Inspecter le cordon d’alimentation : Check the power cord for any damage, fraying, or exposed wires.

Annuellement

• Inspection du réservoir : Visually inspect the air tank for any signs of external corrosion, dents, or damage. If any damage is found, do not use the compressor and seek professional inspection.
• Vérification de la soupape de sécurité : Briefly pull the ring on the safety relief valve to ensure it operates freely and reseats properly.

For any maintenance beyond these basic steps, it is recommended to consult a qualified service technician.
