Final answer:
To make it easier to remove the obturator pad, apply lubricant around the spindle shaft.
Step-by-step explanation:
If the obturator pad is difficult to remove, you can apply lubricant around the spindle shaft to ease its removal. Lubricants such as silicone or oil can help reduce friction and make the pad easier to remove. This is because lubricants create a thin film between two surfaces, reducing the forces that hold them together.
