How to use

Use steady, controlled force to avoid cross-threading and ensure the plug seats properly. After use, wipe the tool clean and store in a dry place.

Recommendations

For safe operation, confirm the spark plug size before use and follow vehicle manufacturer torque specifications when tightening. Avoid excessive force; if a plug is seized, apply penetrating lubricant and allow time to work or consult a professional.
