5. Setup
Follow these steps to prepare your air sander for use:
- Connect Air Supply: Attach your air hose to the tool's air inlet. Ensure a secure connection. It is recommended to use an in-line air filter/lubricator to ensure clean, lubricated air.
- Attach Backing Plate: Select the desired backing plate (25mm, 50mm, or 80mm) and thread it onto the spindle of the sander. Use the provided wrench to tighten it securely.
- Attach Sanding Disc: Choose the appropriate grit sanding disc for your task. The backing plates feature a hook and loop surface. Simply align the sanding disc with the backing plate and press firmly to attach.

6. Operating Instructions
To achieve optimal results and ensure safety, follow these operating guidelines:
- Hold Firmly: Grip the sander firmly with one hand, ensuring a stable and comfortable hold.
- Start Before Contact: Activate the paddle switch to start the sander before bringing the sanding disc into contact with the workpiece.
- Apply Light, Even Pressure: Allow the tool to do the work. Apply only light, even pressure. Excessive pressure can reduce efficiency, damage the disc, and potentially harm the tool or workpiece.
- Consistent Movement: Move the sander in overlapping circular or elliptical patterns across the surface to ensure even material removal and a smooth finish.
- Stop After Lifting: Lift the sander from the workpiece before releasing the paddle switch to stop the tool.
- Grit Selection: Begin with a coarser grit for heavy material removal and progressively move to finer grits for smoothing and finishing.
- Ergonomics: The tool's lightweight and compact design allows for comfortable one-hand operation, reducing fatigue during extended use.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your air sander:
- Disconnect Air: Always disconnect the air supply before performing any maintenance.
- Clean Tool: After each use, wipe down the tool with a clean, dry cloth to remove dust and debris. Use compressed air to blow out any dust from vents and moving parts.
- Lubrication: Apply a few drops of air tool oil into the air inlet before and after each use, or after every hour of continuous operation. This lubricates internal components and prevents corrosion.
- Inspect for Wear: Regularly inspect the backing plate, sanding discs, and air hose for signs of wear or damage. Replace worn or damaged parts immediately.
- Storage: Store the tool in a clean, dry environment, away from direct sunlight and extreme temperatures.
