3. Setup and Loading Staples
The BOSTITCH T6-8 features a convenient bottom-loading mechanism for quick and easy staple reloading.

4. Operating Instructions
Operating the BOSTITCH T6-8 is straightforward due to its ergonomic design and easy-squeeze mechanism.
- Position the Tacker: Place the nose of the tacker firmly against the material you intend to staple. Ensure the tacker is held perpendicular to the surface for optimal staple penetration.
- Engage the Mechanism: Squeeze the handle firmly and smoothly. The patented easy-squeeze mechanism reduces the force required for operation, making it comfortable for extended use.
- Release and Reposition: After the staple is driven, release the handle and reposition the tacker for the next staple.
- Check Staple Depth: Periodically check the depth of staple penetration. If staples are not fully seated, ensure you are applying sufficient pressure to the tacker and squeezing the handle completely.
The tacker is designed to use BOSTITCH STCR5019 Series staples, available in lengths from 1/4 inch to 9/16 inch. Always select the appropriate staple length for your material to ensure secure fastening without over-penetration.

- Jam Clearance: The tacker features tool-free jam clearance. If a staple jam occurs, ensure the tacker is unloaded, then follow the instructions for clearing jams (refer to Troubleshooting section).
