Important Note: This wrench is not intended for use with automotive spark plugs, which typically require higher torque for removal and installation. Attempting to use this tool on automotive spark plugs may result in bending the leverage bar or damage to the tool due to excessive force.
3. Operating Instructions
Follow these steps for safe and effective use of your Briggs & Stratton Spark Plug Wrench:
- Preparation: Ensure the engine is cool before attempting to remove or install spark plugs. Disconnect the spark plug wire to prevent accidental starting.
- Identify Spark Plug Size: Determine if your spark plug requires a 13/16 inch or 5/8 inch socket. The wrench has both sizes available.
- Position the Wrench: Carefully slide the appropriate end of the wrench over the spark plug until it is fully seated.
- Insert Leverage Bar: Insert the provided metal bar through the hole in the wrench. For initial loosening or final tightening, insert the bar fully to maximize leverage. For turning in tight spaces, the bar can be inserted halfway and swiveled.
- Remove Spark Plug: Turn the wrench counter-clockwise to loosen the spark plug. Once loose, you can often remove it by hand.
- Install Spark Plug: Hand-thread the new spark plug into the engine to avoid cross-threading. Once finger-tight, use the wrench to gently tighten the spark plug.
- Tightening: Tighten the spark plug only until it is snug. Over-tightening can damage the spark plug or the engine cylinder head. Refer to your engine's service manual for specific torque specifications if available.
- Final Step: Reconnect the spark plug wire securely.

4. Care and Maintenance
The Briggs & Stratton Spark Plug Wrench 5402K is a durable tool designed for longevity. To ensure its continued performance:
- Cleaning: After each use, wipe the wrench clean with a dry cloth to remove any dirt, oil, or debris.
- Storage: Store the wrench in a dry place to prevent rust. Keep it away from excessive moisture and corrosive materials.
- Inspection: Periodically inspect the wrench for any signs of damage, such as bending or cracking. If the tool is damaged, replace it to ensure safe and effective operation.
5. Troubleshooting
If you encounter issues while using the spark plug wrench, consider the following:
- Wrench Bends During Use: This typically occurs when excessive force is applied, often when attempting to remove spark plugs from applications with higher torque requirements, such as automobiles. This wrench is designed for lawn and garden equipment. Ensure you are using the correct tool for the job.
- Difficulty Reaching Spark Plug: The slim design of this wrench is intended for hard-to-reach spark plugs in small engines. If you still cannot reach the plug, ensure the engine shroud or other obstructions are removed as per your equipment's service manual.
- Spark Plug Not Loosening/Tightening: Ensure the wrench is fully seated on the spark plug. If the plug is seized, apply penetrating oil and allow it to soak before attempting removal again. Avoid excessive force to prevent damage to the engine or tool.
