4. Configuració
4.1 Air Compressor Setup:
- Desembalatge: Traieu amb cura el compressor del seu embalatge. Inspeccioneu-lo per si hi ha hagut danys durant l'enviament.
- Instal·lació del silenciador: Attach the included air filter/muffler assemblies to the intake ports on the pump head.
- Col·locació: Position the compressor on a firm, level surface in a well-ventilated area. Ensure adequate clearance around the unit for air circulation.
- Vàlvula de desguàs: Ensure the drain valve at the bottom of the tank is closed before operation.
- Connexió d'alimentació: Connecteu el cable d'alimentació a una presa de corrent de 12 volts amb connexió a terra.
4.2 Coupler & Plug Kit Setup:
- Identificar els components: Familiarize yourself with the male plugs, female plugs, male couplers, and female couplers.
- Thread Sealant: Apply thread sealant tape (not included) to the male threads of all plugs and couplers before installation to ensure an airtight seal.
- Attach Plugs to Tools: Thread the appropriate male or female plug onto the air inlet of your pneumatic tools. Tighten securely.
- Attach Couplers to Hoses: Thread the appropriate male or female coupler onto the ends of your air hoses. Tighten securely.
- Codificació de colors: Utilize the red color to designate specific air lines (e.g., for lubricated vs. non-lubricated air, or high vs. low pressure) to prevent cross-contamination.
5. Instruccions de funcionament
5.1 Initial Break-in Procedure (Compressor Only):
Before first use, perform a 20-minute break-in to ensure optimal performance and longevity.
- With the power cord plugged in, turn the compressor's power switch to the "ON" position.
- Open the tank drain valve completely (located at the bottom of the tank). This will prevent pressure from building up.
- Allow the compressor to run for 20 minutes with the drain valve open. This helps seat the piston rings.
- After 20 minutes, turn the power switch to "OFF" and close the drain valve.
5.2 Standard Operation:
- Encès: Ensure the drain valve is closed. Turn the power switch to "ON". The compressor will begin to fill the tank.
- Acumulació de pressió: The compressor will run until the tank pressure reaches its maximum (150 PSI), then it will shut off automatically.
- Adjust Output Pressure: Turn the regulator knob clockwise to increase output pressure and counter-clockwise to decrease it. Monitor the "TOOL" gauge for the desired pressure.
- Connecteu l'eina d'aire: Pull back the collar on the quick coupler, insert the air tool's plug, and release the collar to secure the connection.
- Utilitza l'eina: Operate your pneumatic tool as per its own instruction manual. The compressor will cycle on and off automatically to maintain tank pressure as air is consumed.
- Disconnect Tool: Before disconnecting, ensure the air tool is not under pressure. Pull back the quick coupler collar to release the plug.
- Apagar: When finished, turn the power switch to "OFF".
- Dipòsit de drenatge: Slowly open the drain valve to release all air pressure from the tank. Once pressure is at zero, leave the valve open to drain any accumulated moisture. Close the valve before next use.

6. Manteniment
Regular maintenance ensures the longevity and safe operation of your air compressor.
Manteniment diari:
- Dipòsit de drenatge: Always drain condensation from the air tank after each use. This prevents rust and extends tank life.
- Inspeccionar si hi ha fuites: Check all connections and hoses for air leaks. A soapy water solution can be used to detect leaks.
Manteniment setmanal/mensual:
- Filtre d'aire net: The compressor is oil-free, but the air filter should be inspected and cleaned or replaced if dirty to ensure proper airflow to the pump.
- Inspeccioneu el cable d'alimentació: Check the power cord for any signs of damage, fraying, or exposed wires.
- Comprovació dels elements de fixació: Assegureu-vos que totes les femelles, els cargols i les rosques estiguin ben ajustades.
Coupler & Plug Kit Maintenance:
- Neteja: Keep couplers and plugs free from dirt and debris.
- Lubricate (Optional): A small amount of pneumatic tool oil can be applied to the moving parts of couplers to ensure smooth operation, but avoid over-lubrication, especially if using with non-lubricated air tools.
- Inspeccionar el desgast: Replace any worn or damaged couplers or plugs to maintain an airtight seal and prevent air leaks.
