Use the tool both vertically and horizontally with the stem. Handle with care, as this is a precision tool sensitive to impact. Keycap Calibration: Can only be used when the keycap is leveled. Avoid using the tool vertically. If the switch is rotated 90 degrees, use the tool vertically. Trim the stem to remove any burrs. Always use the tool vertically with the stem.
