Before using the thread chaser, ensure the spark plug hole is accessible and clear of any major obstructions. It is recommended to clean the area around the spark plug hole to prevent debris from entering the combustion chamber.

2. Lubrication: Apply a small amount of cutting oil or grease to the threads of the chaser. This will aid in cutting, reduce friction, and help collect metal shavings.
3. Tool Orientation: The unique design of the MS003 allows it to be inserted through the damaged thread and then expanded to engage the undamaged threads deeper within the combustion chamber.
