The tool features a powerful shuttle blade mechanism that pre-compresses the material before and during stapling, ensuring a strong, tight closure without damaging the corrugated surface. Its 6-inch by 1-inch high throat provides ample space for flexible staple placement and minimizes interference from box flanges or other obstacles.

4. Setup
- Air Supply Connection:
- Ensure your air compressor is capable of providing the required air pressure (refer to specifications).
- Connect an air hose to the tool's air inlet. Use a quick-connect fitting for convenience.
- Set the air pressure regulator on your compressor to the recommended operating pressure.
- Loading Staples:
- Disconnect the tool from the air supply before loading staples.
- Locate the staple magazine release mechanism, typically a latch or button.
- Open the magazine and insert a stick of compatible staples (e.g., SB103020 series) into the channel, ensuring they are oriented correctly.
- Close the magazine securely until it latches.
- Initial Test:
- Reconnect the air supply.
- Test the tool on a scrap piece of material to ensure staples are feeding and fastening correctly.
5. Operating Instructions
The Bostitch P51-10B is designed for single-shot stapling. Follow these steps for effective operation:
- Prepare Workpiece: Position the materials to be fastened securely. Ensure the area where the staple will be driven is clear of hands or other obstructions.
- Position Tool: Place the stapling pliers over the material where the staple is to be driven. The high throat allows for flexible placement, even over box flanges.
- Engage and Staple: Firmly press the tool down onto the material. The powerful shuttle blade will pre-compress the material. Once properly seated, squeeze the trigger to drive the staple.
- Inspect Fastening: After each staple, inspect the closure to ensure it is tight and secure. The tool is capable of penetrating and securely fastening up to 2x AB flute or 4x C flute boards.
- Reposition: Release the trigger and reposition the tool for the next staple.
