5. Setup and Installation

Follow these steps to properly install and prepare your in-line oiler for use:

1. Depressurize Air Line: Before installation, ensure that the air compressor is turned off and the air line is completely depressurized.
2. Identify Inlet/Outlet: The oiler has a designated inlet and outlet. The inlet typically features a male NPT thread for connection to the air supply, and the outlet features a female NPT thread for connection to the air tool or whip hose. Refer to the diagram below for clarification.

3. Connect to Air Line:
   • Apply thread sealant (e.g., PTFE tape) to the male NPT threads of the oiler.
   • Connect the male threaded end (Inlet) of the oiler to your air supply hose or quick-connect fitting.
   • Connect your air tool or a whip hose to the female threaded end (Outlet) of the oiler.
   • Ensure all connections are tight to prevent air leaks.
4. Fill with Oil:
   • Locate the small screw on the side of the clear polycarbonate reservoir.
   • Carefully unscrew this filler screw.
   • Using a suitable dispenser, fill the reservoir with pneumatic tool oil. Do not overfill; leave a small air gap at the top.
   • Securely replace the filler screw, ensuring it is tight to prevent leaks.

6. Operating Instructions

Once installed and filled, the Beduan Automatic Mini In-Line Oiler operates automatically with the flow of air.

1. Restore Air Pressure: Turn on your air compressor and allow it to reach its operating pressure. Check all connections for leaks.
2. Tool Operation: As air flows through the oiler to your pneumatic tool, a small amount of oil will be atomized and mixed with the air stream, lubricating the internal components of the tool.
3. Monitor Oil Level: Periodically check the oil level through the clear polycarbonate reservoir. Refill as necessary to ensure continuous lubrication.

7. Maintenance

Regular maintenance ensures the longevity and effective operation of your in-line oiler.

• Refilling Oil: When the oil level in the reservoir is low, depressurize the air line, unscrew the filler screw, and refill with appropriate pneumatic tool oil. Securely replace the screw.
• Inspection: Regularly inspect the oiler for any signs of wear, cracks in the reservoir, or damage to the threads.
• Cleaning: If the reservoir becomes dirty, it can be cleaned by carefully disassembling the unit (after depressurizing) and washing the polycarbonate part with mild soap and water. Ensure it is completely dry before reassembly.
• Storage: If storing the oiler for an extended period, drain any remaining oil and store it in a clean, dry place.
