פֿאַרזאַמלונג
- צוטשעפּען ווהעעלס: Securely attach the wheels to the compressor base using the provided hardware.
- צוטשעפּען שעפּן: Mount the transport handle to the designated points on the compressor body.
- פּאַזישאַנינג: Place the compressor on a firm, level surface. Ensure there is adequate space around the unit for ventilation.
עלעקטריקאַל קאַנעקשאַן
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.

- שטעקט אריין דעם קאמפרעסאר אין א פאסיגע עלעקטרישע ווענטיל.
- 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.
- Attach your air tool to the other end of the hose.
- Adjust the working pressure using the red regulator knob to suit the requirements of your air tool. Monitor the working pressure gauge.
