3. Setup and Staple Loading
3.1 Choosing the Right Staple Size
Selecting the correct staple size is crucial for optimal performance and to prevent jamming. The hammer tacker is compatible with T50 staples. Consider the material you are fastening and the base material:
- Choose staples of appropriate length according to your material. Ensure the staple is fully driven into the material.
- For harder base materials (e.g., Oak, Plywood, MDF), use shorter staples. For softer base materials (e.g., Pine, Douglas Fir, Foam), use longer staples.
- If a staple stands away from the surface after driving, the staple is too long. Choose the next shorter leg length.

Guidance on selecting the appropriate staple length for different materials.
3.2 Loading Staples
Follow these steps to load staples into your hammer tacker:
- Pinch and Press: Pinch and press down the staple magazine release mechanism, typically located at the rear of the tool.
- Pull Out Magazine: Gently pull out the staple magazine until it is fully extended.
- Insert Staples: Place a strip of T50 staples into the magazine with the staple legs facing downwards. Ensure they are seated correctly.
- Close Magazine: Push the staple magazine back into the tool until it clicks securely into place.

- Position Tool: Place the head of the tacker firmly against the material where you wish to drive a staple.
- Strike Surface: Swing the tool down and strike the surface with the head of the tacker, similar to using a hammer. The impact will drive a staple into the material.
