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.
