HOW TO OPERATE

Air Outlet Compatibility

• By default, our air compressor is equipped with a 1/8” BSP outlet. If you require a 1/4” BSP or NPT thread, you will need to use appropriate adapters to connect to your desired air hose. Once properly adapted, you can attach a wide variety of hoses to suit your setup.

Ensuring an Airtight Seal

• The original air hose includes a rubber seal inside, allowing it to achieve an airtight connection by hand for optimal performance. If you're using a nonoriginal hose, a perfect seal may not be achieved. In such cases, we recommend applying Teflon tape (available at most hardware and plumbing supply stores) to the threads to help prevent air leaks.

Basic Setup and Operation

• Connect the air compressor, air hose, and airbrush (or other pneumatic tool). Once everything is securely connected, plug in the power cord and switch on the compressor. The pressure gauge will show the maximum pressure. You can adjust the working pressure to your preference using the regulator knob.

Leak Check Procedure

• Before using your air tools, perform a leak test:
• For compressors with auto-stop, wait until the pressure reaches its maximum and the unit shuts off automatically.
• For compressors without auto-stop, manually switch off the unit when max pressure is reached.

Observe the pressure gauge needle:

• If the needle remains steady, your system is airtight.
• If the needle drops rapidly, there’s a leak in the connection. Locate and fix the leak to prevent performance issues such as frequent cycling of the compressor.

Understanding Maximum vs. Working Pressure

• The maximum pressure is the highest pressure your compressor can build. When you begin airbrushing, the initial air burst is released at this maximum pressure. The working pressure, on the other hand, is the regulated level you set for continuous operation, ensuring smooth and controlled airflow through your airbrush.

Compressor Tank Advantages

• The compressor is equipped with a tank that stores compressed air before delivery to the airbrush or other air tools. This feature offers multiple benefits:
  a. It provides a reservoir of pressurized air, allowing smoother spraying
  b. Supplies regulated air from the tank rather than fluctuating piston output,
  c. Eliminates air pulsations caused by piston motion, improving spray consistency,
  d. Extends compressor life by reducing constant operation, as it only runs when the tank needs refilling, and
  e. The tank also acts as an initial moisture trap, helping reduce condensation in the air supply.

 

Proper Use and Maintenance
Guidelines for Your Air Compressor

To ensure the longevity and safe operation of your air compressor, it is important to follow a regular maintenance routine and adhere to safety precautions.

Start by regularly checking and maintaining key components. This includes draining the tank and filter to keep them dry, inspecting all connecting pipes for wear or damage, monitoring the oil level, and replacing the oil as needed. For best results, it is recommended to use the original manufacturer’s oil.

When selecting an air compressor, make sure its airflow and pressure capacity match the specific needs of your tasks. Before connecting the unit to a power source, confirm that the mains voltage is compatible with the compressor’s motor. Always follow local electrical and safety regulations, and ensure the power socket is properly grounded.

Avoid exposing the compressor to harmful environmental conditions. Never leave the unit in areas with dust, acids, vapors, explosive or flammable gases, or extreme weather such as rain, direct sunlight, fog, or snow. It must be operated in a suitable, well-ventilated environment where the ambient temperature remains between +5°C and +40°C.

For personal safety, never operate the compressor barefoot or with wet hands or feet. Keep children away from the machine while it is operating, and never insert objects into the device. Doing so can result in burns or electric shock.

Do not attempt to open or modify any part of the compressor. If service is needed, contact an authorized service center. When the compressor will not be used for an extended time, open the water drain valve located under the tank to release any collected moisture. Store the unit in a dry, well-ventilated area.

If the compressor will remain unused for a long period, turn it off but restart it occasionally for 3–5 minutes. This keeps the cylinder and piston lubricated and helps prevent rust caused by moisture in the air, ultimately extending the compressor's lifespan.

It is normal for the compressor to release built-up pressure during long periods of inactivity. This automatic pressure relief does not affect performance. However, never ignore air leaks. Ensure all connections are airtight to prevent the compressor from overheating due to pressure loss during operation.

Lastly, avoid touching the compressor while the motor is running, as the temperature can rise significantly. Also, never attempt to change the oil while the unit is still warm to avoid injury.

PREVENTIVE MAINTENANCE

1. Check Oil Level Regularly

a. Ensure that the oil level remains within the designated range marked on the oil sight tube. Do not allow the oil to fall below or exceed these markings. (See Fig. 1)

2. Add or Replace Oil Safely

a. Only add or change the oil after the compressor has been turned off and allowed to cool down. It is strongly recommended to use the original manufacturer’s oil. Be sure to watch the oil change tutorial by scanning the QR code at the bottom of the page. During the oil change, also replace the muffler and rubber plug as shown.
(See Fig. 2)

3. Release Air Pressure

a. To release the internal air pressure, press down on the needle located at the bottom of the compressor. (See Fig. 3) For further instructions, refer to the installation and operation video accessible via the QR code at the bottom of the page.

4. Drain Moisture from the Tank

a. Open the water drain valve located underneath the tank to release any accumulated moisture. (See Figs. 4–5) For additional guidance, please scan the QR code to view the installation operation video.
