5. Setup

Follow these steps to prepare your air die grinder for use:

5.1 Parts Identification

5.2 Connecting to Air Supply

1. Ensure your air compressor meets the suggested 1.5 HP requirement and provides clean, dry air at the recommended pressure (typically 90 PSI).
2. Apply thread sealant tape to the threads of the 1/4-inch air inlet connector.
3. Screw the air inlet connector firmly into the tool's air inlet port.
4. Connect your air hose to the air inlet connector.

5.3 Installing/Changing Collets and Accessories

1. Disconnect the air supply before proceeding.
2. Use the two provided wrenches to loosen the collet nut. One wrench holds the spindle, and the other turns the collet nut.
3. Insert the desired collet (1/4-inch or 1/8-inch) into the collet nut.
4. Insert the grinding accessory (e.g., grinding stone, burr) into the collet, ensuring it is seated securely. Do not insert the accessory too far or too shallow.
5. Tighten the collet nut firmly with the two wrenches. Do not overtighten.

5.4 Initial Lubrication

Before first use and daily thereafter, add a few drops of pneumatic tool oil (provided) into the air inlet. This lubricates the internal components and extends tool life. Some users have noted that the oil hole may not be effective; if so, disassemble the end cap to directly lubricate the gears before initial use.

6. Operating Instructions

The AEROPRO AP17315 is designed for high-speed grinding, port smoothing, general polishing, and deburring in tight areas.

1. Connect Air Supply: Ensure the tool is properly connected to a regulated air supply.
2. Grip the Tool: Hold the pistol grip handle firmly. The insulated ergonomic handle helps prevent cold hands during extended use.
3. Engage Safety Lever: The tool features an integral safety-lock throttle lever. To operate, depress the safety lever and then squeeze the trigger. Release the trigger to stop the tool.
4. Start Grinding: Bring the rotating accessory into contact with the workpiece. Apply steady, even pressure. Avoid excessive force, which can damage the accessory or the tool.
5. Control Speed: Use the speed adjuster to control the rotational speed of the tool for different applications.
6. Rear Exhaust: The rear exhaust system directs air away from the work surface, improving visibility and reducing debris in your immediate work area.
7. Work in Tight Areas: The angled head design allows for easy access to confined spaces.
8. Finish Work: Once finished, release the trigger and disconnect the air supply.

7. Maintenance

Regular maintenance ensures the longevity and efficient operation of your air die grinder.

• Daily Lubrication: Add 3-5 drops of pneumatic tool oil into the air inlet before each use. If the oil port seems ineffective, consider disassembling the end cap for direct lubrication of internal gears as needed.
• Cleanliness: Keep the tool clean and free of debris. Wipe down the exterior after each use.
• Inspect Collet and Nut: Regularly check the collet and collet nut for wear or damage. Replace if necessary to ensure secure accessory retention.
• Air Filter: Ensure your air compressor's air filter is clean and functioning to prevent moisture and contaminants from entering the tool.
• Check for Loose Parts: Periodically check all fasteners and connections. If any part, such as the neck, loosens, tighten it securely.
• Storage: Store the tool in a dry, clean environment when not in use.
