Familiarize yourself with the main components of your compressor. Refer to Figure 1 for an overview of the unit's dimensions and general layout.
Montaža
- Pritrdite kolesa: Securely attach the wheels to the compressor base using the provided hardware.
- Pritrdite ročaj: Mount the transport handle to the designated points on the compressor body.
- Pozicioniranje: Place the compressor on a firm, level surface. Ensure there is adequate space around the unit for ventilation.
Električna povezava
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.

Controls and Gauges

Slika 2: Od blizu view of the twin pressure gauges. One gauge displays the tank pressure, and the other displays the regulated working pressure.

Slika 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.
- Tlačno stikalo: The black box (Figure 3) automatically turns the compressor on and off to maintain tank pressure.
- Manometer za rezervoar: 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).
- Regulator tlaka: 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).
Zagon kompresorja
- Prepričajte se, da je izpustni ventil na dnu rezervoarja zaprt.
- Kompresor priključite v ustrezno električno vtičnico.
- Turn the main power switch to the "ON" position. The compressor will start to build pressure.
- Once the tank reaches its maximum pressure, the compressor will automatically shut off.
Connecting and Using Air Tools
- Connect your air hose to the quick-connect air outlet.
- Na drugi konec cevi pritrdite zračno orodje.
- Adjust the working pressure using the red regulator knob to suit the requirements of your air tool. Monitor the working pressure gauge.
- Begin using your air tool. The compressor will cycle on and off automatically to maintain pressure as needed.
Zapiranje
- Glavno stikalo za napajanje obrnite v položaj "IZKLOP".
- Odklopite zračno cev in orodje.
- Počasi odprite izpustni ventil na dnu rezervoarja, da sprostite kondenzirano vlago in preostali zračni tlak. Ko je rezervoar prazen, ventil zaprite.
Vzdrževanje
Redno vzdrževanje zagotavlja dolgo življenjsko dobo in varno delovanje vašega zračnega kompresorja.
Dnevno/po vsaki uporabi
- Odvod kondenzata: 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
- Preverite zračni filter: Check the air filter for dirt and debris. Clean or replace if necessary to ensure proper airflow to the pump.
- Preverite puščanje: Listen for any air leaks around fittings, hoses, and valves. Tighten connections as needed. A soapy water solution can help identify small leaks.
- Preverite cevi in priključke: Examine air hoses for cracks, cuts, or wear. Replace damaged hoses immediately. Ensure all quick-connect fittings are functioning correctly.
- Preglejte napajalni kabel: Check the power cord for any damage, fraying, or exposed wires.
Letno
- Pregled rezervoarja: 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.
- Preverjanje varnostnega ventila: 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.
