HOW TO USE:

1. Prepare the Workpiece: Ensure the pin you intend to remove is accessible and the surrounding area is clear. Place the workpiece on a stable, solid surface that can absorb impact without damage.
2. Initial Loosening (if needed): If the pin is seized or very tight, first use a solid or taper punch (not this pin punch) to break it free and initiate movement. This tool is not for loosening stuck pins.
3. Position the Pin Punch: Once the pin has some initial movement, place the 5/16″ tip of the Mayhew Hex Pin Punch squarely on the center of the loosened pin.
4. Strike with a Hammer: Using a hammer of appropriate weight, strike the head of the punch firmly and squarely. Apply consistent force to drive the pin out through the other side of the workpiece.
5. Monitor Progress: Continue striking until the pin is fully expelled from the hole. Be careful not to damage the workpiece or the punch by striking off-center.
6. Clean Up: Once the pin is removed, clear any debris and store the punch in a dry place.
