4. Operating Instructions
Adjusting Impact Strength:
The Tolsen 43020 features an impact strength adjustment knob, usually located at the top or rear of the handle.

Test on a scrap piece of material to find the optimal setting for your specific application and material.
Stapling Procedure:
- Select the appropriate staple size and load the magazine as described in Section 3.
- Adjust the impact strength as needed for your material.
- Place the nose of the staple gun firmly against the work surface where the staple is to be driven.
- Squeeze the handle firmly and completely to fire a staple.
- Release the handle and reposition the tool for the next staple.

- Storage: Store the staple gun in a dry environment to prevent rust.
6. Troubleshooting
Common Issues and Solutions:
