5. Setup

Before operating the pneumatic sander, ensure proper setup for safety and optimal performance.

1. Prepare Air Supply: Connect your air compressor to an air hose. Ensure the air compressor is capable of providing 0.6-0.8 Mpa (6-8 bar or 90-120 PSI) working pressure and sufficient airflow for continuous operation.
2. Connect Air Hose: Attach the air hose to the air inlet of the pneumatic sander. Ensure a secure connection to prevent air leaks. (Refer to Figure 2 for air inlet location).
3. Select Sandpaper: Choose the appropriate grit sandpaper for your application. The sander uses a 75x100mm sanding pad.
4. Attach Sandpaper: Align the sandpaper with the sanding pad and firmly press it onto the pad. Ensure it is centered and securely attached.

6. Operation

Follow these steps for effective and safe operation of your pneumatic sander.

1. Power On Air Compressor: Turn on your air compressor and allow it to reach the desired working pressure (0.6-0.8 Mpa).
2. Grip the Sander: Hold the sander firmly with both hands, ensuring a comfortable and secure grip on the non-slip handle.
3. Start Sanding: Place the sanding pad flat against the workpiece. Gently press the sensitive speed switch to start the sander. Apply even, moderate pressure and move the sander in overlapping circular or linear patterns.
4. Adjust Speed (if applicable): The sander operates at 10000 RPM. Maintain consistent movement to avoid creating swirl marks.
5. Monitor Dust: Ensure proper dust extraction or wear appropriate respiratory protection.
6. Finish Sanding: Once the desired finish is achieved, lift the sander from the workpiece and release the speed switch.
7. Disconnect Air Supply: After use, turn off the air compressor and disconnect the air hose from the sander.
