Operating Instructions

Follow these steps to precisely adjust your spark plug gap:

1. Step 1: Screw Spark Plug into Gapping Tool.

   Screw the spark plug into the gapping tool from the bottom. Ensure it is securely threaded.

2. Step 2: Use Feeler Gauge for Measurement.

   Use your desired size feeler gauge to measure the current gap thickness. This will help you determine how much adjustment is needed.

3. Step 3: Adjust Gap Thickness.

   Tighten the knob on the gapping tool until the side electrode compresses to the desired gap thickness, as confirmed by your feeler gauge.

4. Step 4: Remove Spark Plug.

   Unscrew the knob to loosen the spark plug and carefully remove it from the gapping tool. Your spark plug gapping adjustment is now complete.

Important Note:

For more precise gapping, it is recommended to use a feeler gauge that is 0.001-inch smaller than your target gap. This accounts for any slight spring-back of the electrode after adjustment, ensuring a higher precise final gap.

Maintenance

To ensure the longevity and continued precision of your Toolwiz Spark Plug Gap Tool, follow these simple maintenance guidelines:

• Cleaning: After each use, wipe down the tools with a clean, dry cloth to remove any debris, oil, or residue.
• Storage: Store the tools in a dry environment to prevent corrosion. Keep them in their original packaging or a tool box to protect them from impacts and scratches.
• Inspection: Periodically inspect the threads and the adjustment knob for any signs of wear or damage. Ensure the screw mechanism operates smoothly.
• Lubrication: A very light application of a general-purpose lubricant to the screw mechanism can help maintain smooth operation, if needed. Avoid excessive lubrication.

Troubleshooting

While the Toolwiz Spark Plug Gap Tool is designed for straightforward operation, here are some common issues and their solutions:

• Spark Plug Not Fitting:

  Ensure you are using the correct size tool (12mm or 14mm) for your spark plug. The tool is not compatible with shorter reach spark plugs. Do not force the spark plug into the tool.
• Difficulty Adjusting Gap:

  Check if the spark plug is fully threaded into the tool. The adjustment knob should turn smoothly. If it feels stiff, ensure there's no debris in the threads. A very light lubricant might help if the mechanism is dry.

• Inaccurate Gap Measurement:

  Always use a calibrated feeler gauge for accurate measurements. Remember the tip about using a feeler gauge 0.001-inch smaller than the target gap to account for electrode spring-back.

• Damage to Spark Plug Electrode:

  This tool is designed to close the gap, not open it. Forcing the gap open with this tool or using excessive force when tightening can damage the electrode. Always use gentle, controlled pressure.
