HOW TO USE:
- Identify the Pin: Locate the pin or key you intend to remove. Ensure it is a 4mm pin for proper tool compatibility.
- Loosen the Pin: If the pin is seized or tight, first use a solid punch of appropriate size to initiate movement and loosen it. The Mayhew 21510 is designed for already loosened pins, not for initial breaking free of seized components.
- Position the Punch: Place the 4mm pin end of the Mayhew 21510 directly onto the center of the loosened pin. Ensure the punch is perpendicular to the surface to avoid glancing blows.
- Strike the Punch: Using a hammer (preferably a ball-peen or soft-face hammer), strike the striking end of the Mayhew 21510 firmly and squarely. Apply controlled force to drive the pin out.
- Monitor Progress: Continue striking as needed, monitoring the pin's movement until it is fully driven out of its bore.
- Retrieve Pin: Collect the removed pin. Clean the workpiece if necessary.
- Store Punch: After use, wipe the punch clean and store it in a dry place to maintain its black oxide finish and prevent damage.
